Description

Technical Field

[0001] The present invention relates to the technical field of engines, in particular to a methanol-heating type methanol engine. Background Art

[0002] A methanol engine refers to an internal combustion engine that uses methanol as fuel. Methanol is a clean, renewable energy source that has been widely studied and used to replace traditional petroleum fuels such as gasoline and diesel. As a liquid fuel, methanol has a simple production process and high combustion efficiency, while also reducing air pollution and greenhouse gas emissions.

[0003] For example, announcement number: CN2525264Y discloses a "heated methanol engine", which uses the engine's circulating hot water channel to surround the intake branch pipe to form two independent channels. The waste heat of the circulating water temperature during engine operation is used to heat the low-temperature methanol atomized gas to increase the atomization degree of the methanol fuel, make it burn more completely, and improve the effective utilization rate of the fuel.

[0004] However, in the prior art, during the continuous operation of the engine, the water temperature in the circulating water channel will gradually increase. In order to avoid the internal temperature of the engine from being too high, a heat dissipation structure is required to cool the water. In the prior art, when cooling the high-temperature water inside the water channel, all the water inside the water channel is cooled. The calorific value of the cooled water is reduced, and when the freshly replenished fuel is heated again, the heating effect will become poor, which can easily cause insufficient atomization of the methanol fuel, and part of the methanol is not fully vaporized and burned, resulting in fuel waste, and at the same time causing pollution to the environment. If the cooling water is not cooled, the engine temperature will be too high, causing engine damage. Summary of the invention

[0005] The purpose of the present invention is to provide a methanol heating type methanol engine to solve the problem proposed in the above background technology that when the cooled water is used to heat the freshly replenished methanol fuel due to the reduced calorific value, the heating effect will become poor, which may easily cause insufficient atomization of the methanol fuel and insufficient gasification and combustion of part of the methanol, resulting in fuel waste and environmental pollution.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, when the No. 1 temperature sensor detects that the internal temperature of the methanol heating box reaches the set value, the thermostat will open the No. 3 return pipe to allow the cooling water in the engine body to enter the radiator box, and the cooling water is dissipated by the radiator box. Then, a large cycle is formed by the No. 2 water inlet pipe, the water pump, the water outlet pipe, the No. 2 return pipe and the engine body to avoid excessive water temperature causing excessive engine temperature. At the same time, part of the hot water for heat dissipation is passed into the U-shaped radiator pipe through the thermostat, and the methanol is fully heated through the heat conduction plate, while avoiding excessive temperature inside the engine.

[0020] 2. In the present invention, when the engine body is initially started, the overall temperature is low, and the temperature of the cooling water is low. Through the connection between the No. 1 water inlet pipe, the water pump, the water outlet pipe, the thermostat, the No. 2 return pipe and the engine body, the cooling water forms a small circulation inside the engine body, which can quickly increase the water temperature and avoid a large amount of water entering the radiator box to cause a large amount of heat loss. As the water temperature rises, the heat conduction plate quickly heats the methanol heating box and heats the methanol fuel inside it, which can improve the stability of the engine body at the initial start-up.

[0021] 3. In the present invention, when the heat sink is cooling water, the No. 2 temperature sensor inside it detects that the water temperature is too high. At this time, the control system controls the No. 1 electromagnet and the No. 2 electromagnet to generate attraction for each other. Under the action of attraction, the No. 2 electromagnet drives the No. 3 connecting shaft to pull the connecting sleeve to slide along the No. 2 connecting shaft and the surface of the card plate. At this time, the No. 3 bevel gear is meshed with the No. 2 bevel gear, and the No. 4 pulley drives the fan blades to ventilate and cool the heat sink to avoid excessive water temperature. When the water temperature drops to the set range, the No. 1 electromagnet and the No. 2 electromagnet generate a repulsive force, and the spring restores the deformation at the same time, and the No. 3 bevel gear is reset to avoid the fan blades from being in continuous ventilation operation, resulting in too low water temperature inside the U-shaped heat sink, and insufficient heating of the methanol heating box.

[0022] 4. In the present invention, the ventilation mechanism is driven by the power output shaft to reduce the use of power source and the number of driving cycles of the engine body, thereby reducing the overall failure rate. The ventilation mechanism is started and stopped according to the water temperature to prevent the power output shaft from always doing work on the external output, so that the power of the engine body can be distributed more optimally.

[0036] In this embodiment, methanol fuel is delivered to the interior of the methanol heating tank 12 through an external supply pump, and then supplied to the interior of the engine body 11 for combustion through the fuel delivery pump 13. When the engine body 11 is initially started, the overall temperature is low and the temperature of the cooling water is low. At this time, the power output shaft 14 drives the water pump 21 to operate, and the water pump 21 flows the water inside the engine body 11 through the No. 1 water inlet pipe 23 into the thermostat 37 through the water outlet pipe 25. At this time, the temperature inside the methanol heating tank 12 detected by the No. 1 temperature sensor inside the methanol heating tank 12 is low and needs to be heated.

[0045] In this embodiment, the ventilation mechanism 7 is driven to operate by the power output shaft 14, which can reduce the use of power sources, reduce the number of driving forces used by the engine body 11 during operation, and reduce the overall failure rate. The ventilation mechanism 7 performs start-stop control according to the water temperature to prevent the power output shaft 14 from always doing work on the external output, so that the power of the engine body 11 can be more optimally distributed. The slider 519 slides along the inside of the slide rail 518 to limit the movement of the No. 2 fixed plate 520, thereby improving the stability of the No. 3 bevel gear 515 on the upper part of the No. 2 fixed plate 520 during horizontal movement and rotation. By clamping the clamping groove with the clamping plate 512, the No. 2 connecting shaft 56 can drive the connecting sleeve 511 to rotate while sliding along the inside of the connecting sleeve 511.

[0046] The use method and working principle of this device are as follows: methanol fuel is delivered to the interior of the methanol heating tank 12 through an external supply pump, and then supplied to the interior of the engine body 11 for combustion through the fuel delivery pump 13. When the engine body 11 is initially started, the overall temperature is low, and the temperature of the cooling water is low. At this time, the power output shaft 14 drives the water pump 21 to operate, and the water pump 21 flows the water inside the engine body 11 through the No. 1 water inlet pipe 23 and into the thermostat 37 through the water outlet pipe 25. At this time, the temperature inside the methanol heating tank 12 detected by the No. 1 temperature sensor inside the methanol heating tank 12 is low, and it needs to be heated. The No. 3 reflux pipe 39 is closed through the thermostat 37, so that the water inside the engine body 11 is introduced into the interior of the engine body 11 through the No. 2 reflux pipe 38. The water is continuously heated by the operation of the engine body 11, and at the same time, part of the water is passed through the thermostat 37. The cooling water enters the U-shaped heat dissipation pipe 32 through the No. 3 water inlet pipe 33, heats the heat conducting plate 31 through the U-shaped heat dissipation pipe 32, flows back to the No. 3 return pipe 39 through the No. 1 return pipe 35, and completes the circulation through the heat dissipation box 22, the No. 2 water inlet pipe 24 and the water pump 21, so as to prevent the cooling water from entering the engine body 11 again through the heat dissipation of the heat dissipation box 22 when the engine body 11 is started, causing the water temperature to rise slowly. Through the No. 1 water inlet pipe 23, the water pump 21, the water outlet pipe 25, the thermostat 37, the No. 2 return pipe 38 and the engine body 11, the cooling water forms a small circulation inside the engine body 11, so that the water temperature can be quickly increased, and a large amount of water can be prevented from entering the heat dissipation box 22 to cause a large amount of heat loss. As the water temperature rises, the heat conducting plate 31 quickly heats the methanol heating box 12 to heat the methanol fuel inside it.

[0047] When the No. 1 temperature sensor detects that the internal temperature of the methanol heating box 12 reaches the set value, the thermostat 37 will open the No. 3 return pipe 39, so that the cooling water in the engine body 11 enters the radiator box 22, and the cooling water is dissipated by the radiator box 22, and then the No. 2 water inlet pipe 24, the water pump 21, the water outlet pipe 25, the No. 2 return pipe 38 and the engine body 11 form a large circulation;

[0048] When the heat sink 22 is cooling the water, the No. 2 temperature sensor inside it detects that the water temperature is too high. At this time, the control system 8 controls the No. 1 electromagnet 517 and the No. 2 electromagnet 521 to generate attraction between each other. Under the action of the attraction, the No. 2 electromagnet 521 drives the No. 3 connecting shaft 514 to pull the connecting sleeve 511 to slide along the surface of the No. 2 connecting shaft 56 and the clamping plate 512. At this time, the No. 3 bevel gear 515 is meshed with the No. 2 bevel gear 510. Under the rotation of the power output shaft 14, the No. 1 pulley 41, the No. 1 connecting belt 42 and the No. 2 pulley 54 are driven to rotate, and then the No. 2 pulley 54 drives the No. 1 connecting shaft 53, the No. 1 bevel gear 58, the No. 2 bevel gear 59 and the No. 3 bevel gear 515 to rotate. Bevel gear No. 510, bevel gear No. 3 515 and connecting shaft No. 3 514 rotate, and the connecting sleeve No. 511, clamping plate 512, connecting shaft No. 2 56 and pulley No. 3 57 are driven to rotate by the rotation of connecting shaft No. 3 514, and finally the connecting belt No. 2 62 and pulley No. 4 61 are driven to rotate, and the fan blades 72 are driven by the pulley No. 4 61, and the heat sink 22 is ventilated and cooled by the fan blades 72 to avoid excessive water temperature. When the water temperature drops to the set range, the repulsive force is generated by the electromagnet No. 1 517 and the electromagnet No. 2 521, and the deformation is restored by the spring 513 to reset the bevel gear No. 3 515 to avoid the fan blades 72 from being in ventilation operation all the time.
