One part enters a fuel tank heating pipe, and the other part enters a cab heating pipe.

Description

Technical fields:

[0001] This invention relates to a fuel supply system and control method for a biomass fuel external combustion engine vehicle. Background technology:

[0002] According to a report on the Yeeyan website titled "New Alloy Can Directly Convert Heat into Electricity," a new type of non-magnetic alloy material, when placed on a copper plate underneath, suddenly becomes strongly magnetic when slightly heated. Researchers at the University of Minnesota have discovered that a new alloy with unique properties can directly convert heat into electricity. This alloy, composed of iron, nickel, cobalt, manganese, and tin, can exhibit either non-magnetic or strongly magnetic properties depending on the temperature. According to a press release from the University of Minnesota, under certain conditions, the new alloy—Ni45Co5Mn40Sn10—undergoes a reversible phase transition: that is, a solid transforms into another type of solid when the temperature changes. Specifically, the new alloy changes from non-magnetic to strongly magnetic; in this process, only a slight increase in temperature is needed. When the heated alloy is placed near a permanent magnet—such as a rare-earth magnet—the magnetic force of the alloy suddenly and dramatically increases. Current is generated in the surrounding coils. Researchers say that a process called hysteresis causes heat loss, but this new alloy exhibits low hysteresis characteristics. Because of this, it can convert a large amount of waste heat into electrical energy. Obviously, this material can be used in automobile exhaust pipes. Some car manufacturers have begun to develop heat exchange equipment that can convert automobile exhaust into usable electrical energy. One car company is using an alloy called cobaltite, which is a mixture of rare earth-doped cobalt and arsenic materials. The new alloy belongs to a thermomagnetic material.

[0003] A steam engine used in a locomotive: steam from the boiler drives a reciprocating piston to rotate the wheels. A Lissling engine is an external combustion engine that uses hot gases from fuel combustion to drive a reciprocating piston. It can use heavy oil or biomass fuel. The structural principle of an external combustion engine is as follows: A permanent magnet synchronous motor drives two rotary piston compressors. A fuel pump draws fuel from the fuel tank, which is then injected through an electric fuel regulator valve into the combustion chamber and ignited by an air plasma flame igniter. Compressed air from the two rotary piston compressors alternately passes through their respective pressure check valves into the front end of a brass carbon fiber turbine, or compressed air from a fan compressor, supporting complete combustion of the fuel on the brass carbon fiber turbine. The high-temperature, high-pressure gas from the brass carbon fiber turbine enters the cylindrical cylinder of the rotary piston engine, driving the cylinder through a fixed piston. The two rotary piston engines together drive the input shaft via a thermomagnetic generator and a thermomagnetic motor; then the permanent magnet synchronous motor becomes a permanent magnet generator to supply power to the external combustion engine powertrain. The input shaft drives the load via an electromagnetic continuously variable transmission.

[0004] The continuous steam explosion process, as described in Chapter 2, Section 3, "Stake Process," of the book "Principles and Applications of Steam Explosion Technology" edited by Chen Hongzhang and Liu Liying, includes five parts: biomass storage and processing equipment, the StakeTech system, water extraction equipment, alkali extraction equipment, and waste treatment equipment.

[0005] Biomass storage and processing unit: Wood chips or chopped straw are piled up and conveyed by pneumatic airflow to a hydrocyclone at the top of the storage tank. The hydrocyclone separates the material from the conveying airflow. The material falls directly from the hydrocyclone into the storage tank, and is then conveyed by a screw conveyor to a covered scale to measure the material flow rate. Water is then added to the material to bring the moisture content to 50%, and it is then conveyed by a screw conveyor to an inclined plate feed chute, where the material is poured into the StakeTech system.

[0006] The StakeTech system consists of a coaxial feeder (Co-Ax feeder) and a digester. The feeder has a large hopper located at the bottom of the inclined plate feed chute. Biomass sliding down from the inclined plate feed chute is conveyed to the large hopper of the Co-Ax feeder by a reversible bidirectional screw conveyor. Within the Co-Ax feeder, the material is compressed into plug-like hard masses, thereby sealing the high-pressure digester.

[0007] Once the compressed material enters the digester, it is broken up by an adjustable valve and quickly exposed to the digester's operating temperature and pressure. A variable-speed screw conveyor in the vertical section of the digester transports the material to the digester's outlet. The processing time of the material in the reactor can be adjusted by regulating the conveying speed of this screw conveyor.

[0008] Saturated steam is introduced through an inlet pipe located at the end of the vertical section of the digester, near the inlet. The operating temperature and pressure are generally 200℃ / 1.55MPa to 238℃ / 3.2MPa, and the holding time is 1 to 5 minutes.

[0009] The end of the digester is the discharge port. The material is conveyed and squeezed to the ball valve through left and right threads. The ball valve can release and explode the material at regular intervals, quickly converting the high pressure inside the tank to the external atmospheric pressure. Usually, the ball valve is set to open once every 5 to 10 seconds, with a duration of 0.5 to 1 second.

[0010] Chapter 3, Section 3, "Steam Explosion Equipment," page 112, subsection 3.3.2.2, "Continuous Steam Explosion Reactors": Because a steam explosion reactor is a high-pressure vessel using steam as the reaction medium, continuous operation is difficult to achieve. Currently, only Stake Technology possesses continuous steam explosion reactors. This company has long conducted in-depth research and development on key equipment related to steam explosion technology and holds numerous patents. A continuous steam explosion reactor includes a feeding system, anti-backflow device, a horizontal tube continuous cooker, and a discharge system. Summary of the Invention:

[0011] The fuel supply system of a biomass fuel external combustion engine vehicle mainly consists of a fuel tank, fuel lines, a fuel pump, an electric fuel regulator valve, and fuel injectors. A stainless steel wire tube is fitted over a rubber hose to form the fuel line. One section of the fuel line connects to the bottom of the fuel tank to the fuel pump inlet, and another section connects to the electric fuel regulator valve inlet. A copper tube from the electric fuel regulator valve connects to the fuel injector inlet. The fuel tank consists of an inner tank and an outer tank. The inner tank is welded from corrugated steel and wrapped with ceramic fiber, which is then covered by the outer tank. A stainless steel expansion tube is vertically installed inside the inner tank. The lower end of the expansion tube connects to the fuel line at the bottom of the inner tank. The expansion tube has many small holes, and its upper end extends beyond the biomass fuel level. A temperature sensor probe is installed near the bottom of the inner tank, close to the lower end of the expansion tube. The fuel lines, fuel pump, electric fuel regulator valve, and copper tube are all wrapped with insulating material. The exhaust pipe of the external combustion engine connects to the inlet of the first Y-shaped tee, which is equipped with a fuel tank heater valve. The electric regulating valve has one outlet of the first Y-shaped tee connected to the fuel tank heater pipe inlet, which in turn connects to the bottom of the outer casing. The top of the outer casing has an air vent. The other outlet of the first Y-shaped tee connects to the inlet of the intermediate pipe. The outlet of the intermediate pipe connects to the inlet of the second Y-shaped tee, which houses the cab heater electric regulating valve. One outlet of the second Y-shaped tee connects to the cab heater pipe inlet, and the other outlet connects to the exhaust pipe inlet. A low-voltage DC current is connected between the output copper pipe of the electric fuel regulating valve and the upper end of the stainless steel expansion tube. The exhaust pipe, the first Y-shaped tee, the fuel tank heater pipe, the intermediate pipe, the second Y-shaped tee, the cab fuel / gas pipe, and the exhaust pipe have rectangular cross-sections. The valve plates of the fuel tank heater electric regulating valve and the cab heater electric regulating valve are rectangular steel plates.

[0012] Control method of fuel supply system for biomass fuel external combustion engine vehicles. Straw processed by a screw extrusion continuous steam detonator is soaked in water. 30% of the straw processed by the screw extrusion continuous steam detonator is soluble in water, 30% is partially dissolved in water forming an emulsion, and the remaining material is plant fiber that is insoluble in water. The straw processed by the screw extrusion continuous steam detonator is spun dry using a centrifuge with a filter screen. The straw processed by the screw extrusion continuous steam detonator is then soaked in water to obtain a golden-yellow emulsion containing moisture. A small amount of heavy oil and solvent are then added to produce biomass blended fuel. When the air temperature is below 0℃ and the external combustion engine is not running, if the temperature sensor probe inside the inner tank detects that the biomass blended fuel inside the inner tank is below 0℃, the computer controller increases the voltage of the adjustable DC power supply between the output copper steel of the fuel electric regulating valve and the upper end of the stainless steel expansion tube. If the temperature sensor probe inside the inner tank detects that the biomass blended fuel inside the inner tank is above 1℃, the computer controller decreases the voltage of the low-voltage DC power supply between the output copper steel of the fuel electric regulating valve and the upper end of the stainless steel expansion tube to ensure that the temperature of the biomass blended fuel near the lower end of the stainless steel expansion tube is above 0℃.The biomass blended fuel inside the inner tank expands as it freezes from the surface downwards, forcing the liquid biomass blended fuel below through the stainless steel expansion tube to the ice surface, where it freezes. The heat generated by the low-voltage DC current between the output copper steel of the fuel electric regulating valve and the upper end of the stainless steel expansion tube keeps the biomass blended fuel in a liquid state above 0°C. Starting the fuel pump allows fuel to be supplied to the biomass blended fuel external combustion engine vehicle. When starting the biomass blended fuel external combustion engine vehicle, the permanent magnet synchronous motor drives the biomass blended fuel external combustion engine to rotate, and then the fuel pump starts. The fuel pump draws fuel from near the stainless steel expansion tube, which is then sprayed from the fuel nozzle through the fuel electric regulating valve and ignited by the air plasma flame. With the help of compressed air, the biomass blended fuel is fully combusted on the copper alloy carbon fiber plate. The resulting high-temperature, high-pressure gas, when the cam pushes the driven roller to open the intake valve, enters the rotary piston engine cylinder to drive... The rotary piston rotates, and the hot gas from the rotary piston engine enters the thermomagnetic motor, amplifying the AC power of the thermomagnetic motor to drive its rotor. Then, the power supply to the permanent magnet synchronous motor stops. After the biomass blended fuel external combustion engine vehicle starts, the waste heat gas from the thermomagnetic motor enters the exhaust pipe, passes through the first Y-shaped three-way valve, the fuel tank heater electric regulating valve, the fuel tank heater pipe, and then enters the gap between the outer and inner tanks of the fuel tank, heating the frozen biomass blended fuel inside the inner tank, causing it to melt. If there is a circuit fault, the output copper steel of the fuel electric regulating valve cannot connect to the upper end of the stainless steel expansion tube, causing all the biomass blended fuel inside the inner tank to freeze. Since the inner tank is made of corrugated steel, the volume of the biomass blended fuel increases after freezing and expansion. The deformation of the corrugated steel in the inner tank 1 can withstand the increased volume of the biomass blended fuel after freezing and expansion. When the stainless steel expansion pipe, fuel pipe, fuel pump, electric fuel regulating valve, and copper pipe freeze, a heat gun is used to sequentially heat the copper pipe, the electric fuel regulating valve, the fuel pipe between the electric fuel regulating valve and the fuel pump, the fuel pump, the fuel pipe between the fuel pump and the stainless steel expansion pipe, and the bottom of the fuel tank near the fuel pipe, melting the biomass fuel inside. After starting the biomass blended fuel external combustion engine vehicle, when the temperature of the biomass blended fuel in the inner tank exceeds 15℃, the computer controller reduces the electric regulating fuel tank heating valve, allowing some hot exhaust gas to enter the intermediate pipe, and then through the electric regulating cab heating valve into the cab heating pipe. When the temperature inside the cab exceeds 15℃, the computer controller reduces the electric regulating cab heating valve, allowing some hot exhaust gas entering the intermediate pipe to enter the external exhaust pipe. In summer, when the temperature exceeds 20℃, the cab temperature is set between 20℃ and 26℃. The computer controller closes the electric regulating fuel tank heating valve, allowing all hot exhaust gas to enter the intermediate pipe, and then closes the electric regulating cab heating valve, allowing all hot exhaust gas entering the intermediate pipe to enter the external exhaust pipe.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] Figure 1 This is a schematic diagram of the fuel supply system of the biomass fuel external combustion engine vehicle of the present invention. Detailed implementation method:

[0015] Figure 1 As shown, this is the fuel supply system of a biomass fuel external combustion engine vehicle. The vehicle's fuel supply system mainly consists of a fuel tank, fuel lines, a fuel pump 4, an electric fuel regulating valve 5, and fuel injectors 6. A stainless steel wire tube is sleeved on a rubber tube to form the fuel line. One section of the fuel line connects from the bottom of the fuel tank to the inlet of the fuel pump 4, and another section of the fuel line from the fuel pump connects to the inlet of the electric fuel regulating valve 5. A copper tube from the electric fuel regulating valve 5 connects to the inlet of the fuel injector 6. The fuel tank consists of an inner tank 1 and an outer shell 2. The inner tank 1 is welded from corrugated steel and wrapped with ceramic fiber, which is then covered by the outer shell 2. A stainless steel expansion tube 3 is vertically installed inside the inner tank 1. The lower end of the stainless steel expansion tube 3 is connected to the fuel line at the bottom of the inner tank 1. The stainless steel expansion tube 3 has many small holes, and its upper end extends beyond the biomass fuel liquid surface. A temperature sensor probe is installed at the bottom of the inner tank 1 near the lower end of the stainless steel expansion tube 3. The fuel line, fuel pump 4, fuel electric regulating valve 5, and copper pipe are all wrapped with heat-insulating material. The exhaust pipe 7 of the external combustion engine is connected to the inlet of the first Y-shaped tee. The first Y-shaped tee is equipped with the fuel tank heater electric regulating valve 8. One outlet of the first Y-shaped tee is connected to the inlet of the fuel tank heater pipe 9. The outlet of the fuel tank heater pipe 9 is connected to the bottom of the outer casing 2. The top of the outer casing 2 has an air vent. The other outlet of the first Y-shaped tee is connected to the inlet of the intermediate pipe 10. The outlet of the intermediate pipe 10 is connected to the inlet of the second Y-shaped tee. The second Y-shaped tee is equipped with the cab heater electric regulating valve 11. One outlet of the second Y-shaped tee is connected to the inlet of the cab heater pipe 12. The other outlet of the second Y-shaped tee is connected to the inlet of the external exhaust pipe 13. A low-voltage DC power supply is connected between the output copper pipe of the fuel tank electric regulating valve 5 and the upper end of the stainless steel expansion tube 3. The exhaust pipe 7, the first Y-shaped tee, the fuel tank heater pipe 9, the intermediate pipe 10, the second Y-shaped tee, the cab oil and gas pipe 12, and the external exhaust pipe 13 have rectangular cross sections. The valve plates of the fuel tank heater electric regulating valve 8 and the cab heater electric regulating valve 11 are rectangular steel plates.

[0016] Figure 1The diagram illustrates the control method for the fuel supply system of a biomass fuel-powered external combustion engine vehicle. Straw treated by a screw extrusion continuous steam detonator is soaked in water. Of the straw treated by this process, 30% is soluble in water, 30% is partially dissolved forming an emulsion, and the remaining material, consisting of plant fibers, is insoluble. The straw is then centrifuged using a filter screen. After further soaking in water, a golden-yellow emulsion containing moisture is obtained. A small amount of heavy oil and solvent are added to create biomass blended fuel. This fuel is used when the temperature is below 0°C and the external combustion engine is not operating. When the temperature sensor probe inside the inner tank 1 detects that the biomass blended fuel inside the inner tank 1 is below 0°C, the computer controller increases the voltage of the adjustable DC power supply between the output copper plate of the fuel electric regulating valve 5 and the upper end of the stainless steel expansion tube 3. When the temperature sensor probe inside the inner tank 1 detects that the biomass blended fuel inside the inner tank 1 is above 1°C, the computer controller decreases the voltage of the low-voltage DC power supply between the output copper plate of the fuel electric regulating valve 5 and the upper end of the stainless steel expansion tube 3, ensuring that the temperature of the biomass blended fuel near the lower end of the stainless steel expansion tube 3 is above 0°C. The biomass blended fuel inside the inner tank 1 expands as it freezes from the surface downwards, increasing its volume and causing the liquid biomass blended fuel below to be pushed through the stainless steel expansion tube. Pipe 3 is pressed onto the ice surface and freezes. The heat generated by the low-voltage DC current between the output copper steel of the fuel electric regulating valve 5 and the upper end of the stainless steel expansion tube 3 keeps the biomass blended fuel in a liquid state above 0°C. Starting the fuel pump 4 can supply fuel to the biomass blended fuel external combustion engine vehicle. When the biomass blended fuel external combustion engine vehicle needs to be started, the permanent magnet synchronous motor drives the biomass blended fuel external combustion engine to rotate, and then the fuel pump 4 is started. The fuel pump 4 draws fuel from near the stainless steel expansion tube 3, which is sprayed out from the fuel nozzle 6 through the fuel electric regulating valve 5 and ignited by the air plasma flame. With the help of compressed air, the biomass blended fuel is fully heated on the copper alloy carbon fiber plate. Combustion produces high-temperature, high-pressure gases that, when pushed by the cam to open the intake valve, enter the cylinder of the rotary piston engine, driving the rotary piston to rotate. The hot gases exiting the rotary piston engine enter the thermomagnetic motor, amplifying the AC power and driving the rotor of the thermomagnetic motor to rotate, and then stopping the power supply to the permanent magnet synchronous motor. After the biomass blended fuel external combustion engine vehicle starts, the waste heat gases from the thermomagnetic motor enter the exhaust pipe 7, pass through the first Y-shaped tee, the fuel tank heater electric regulating valve 8, the fuel tank heater pipe 9, and then enter the gap between the outer shell 2 and the inner tank 1 of the fuel tank, heating the frozen biomass blended fuel in the inner tank 1 and melting it.If there is a circuit fault, the output copper steel of the fuel electric regulating valve 5 cannot be connected to the upper end of the stainless steel expansion tube 3, causing all the biomass blended fuel in the inner tank 1 to freeze. Since the inner tank 1 is made of corrugated steel, the volume of the biomass blended fuel inside the inner tank 1 increases after freezing and expansion. The deformation of the corrugated steel in the inner tank 1 can withstand the increased volume of the biomass blended fuel inside the inner tank 1 after freezing and expansion. The stainless steel expansion tube 3, fuel pipe, fuel pump 4, fuel electric regulating valve 5, and copper pipe freeze. It is necessary to use a power heater to heat the copper pipe, fuel electric regulating valve 5, the fuel pipe between fuel electric regulating valve 5 and fuel pump 4, fuel pump 4, the fuel pipe between fuel pump 4 and stainless steel expansion tube 3, and the bottom of the fuel tank shell 2 near the fuel pipe in sequence, so that the biomass inside freezes. When a biomass-blended fuel oil engine is started, and the temperature of the biomass-blended fuel oil in the inner tank 1 exceeds 15℃, the computer controller reduces the pressure of the electrically adjustable fuel tank heater valve 8, allowing some hot exhaust gas to enter the intermediate pipe 10, and then through the electrically adjustable cab heater valve 11 into the cab heater pipe 12. When the temperature inside the cab exceeds 15℃, the computer controller reduces the pressure of the electrically adjustable cab heater valve 11, allowing some of the hot exhaust gas entering the intermediate pipe 10 to enter the exhaust pipe 13. In summer, when the temperature exceeds 20℃, the cab temperature is set between 20℃ and 26℃. The computer controller closes the electrically adjustable fuel tank heater valve 8, allowing all the hot exhaust gas to enter the intermediate pipe 10, and then closes the electrically adjustable cab heater valve 11, allowing all the hot exhaust gas entering the intermediate pipe 10 to enter the exhaust pipe 13.

When the cam pushes the driven roller to open the intake valve, the high-pressure gas enters the cylinder of the rotary piston engine and drives the rotary piston to rotate.
