[0033] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1

[0035] like Figures 1 to 5 As shown, the present invention provides a low-pressure engine direct drive control system, including a temperature control mechanism 1, the center position of the upper right end of the temperature control mechanism 1 is connected to a main flow conduit 2, the front and rear sides of the main flow conduit 2 are both provided with the same branch pipe 21, and the other side of the main flow conduit 2 is connected to an engine fuel supply tank 3, the other side of the branch pipe 21 is connected to an engine housing 4, and the left and right sides of the upper end of the engine fuel supply tank 3 are provided with an inlet and outlet air system 5;

[0036] An engine housing 4 is provided with a crankshaft connecting rod mechanism 41 at the upper end of the engine housing 4, and a starting system 6 is provided inside the engine housing 4. An output shaft 61 is provided at the center position of the front end on the right side of the starting system 6, and a stabilizing connecting pipe 7 is wrapped around the outer side of the output shaft 61. The right side of the stabilizing connecting pipe 7 is connected to a control system box 8.

[0037] Further, the temperature control mechanism 1 includes a heating wire layer 11, the outer side of the heating wire layer 11 is wrapped with a protective shell, a temperature control water layer 12 is arranged on the right side of the protective shell, the temperature control water layer 12 is a trapezoidal structure, and the center position of the upper end of the temperature control water layer 12 is connected to the main flow conduit 2 and the branch pipe 21, a heat preservation layer 13 is arranged on the right side of the temperature control water layer 12, a connecting frame 14 is arranged at the center position of the right side of the heat preservation layer 13, and protective metal sheets 15 are arranged at the front and rear ends of the temperature control mechanism 1. Overheating of the engine will lead to a decrease in the charging efficiency, thereby reducing the power of the engine. Overheating will increase the possibility of pre-ignition and deflagration, which will cause the parts to bear additional impact loads and may cause early damage. Overheating will destroy the normal clearance of moving parts, causing movement blockage, aggravated wear, and may even cause damage. Overheating will worsen lubrication and aggravate friction and wear of parts. Overheating will also cause the mechanical properties of parts to decrease, which may cause deformation or damage. Therefore, cooling water is placed in the temperature control water layer 12. Then, when the weather is hot and the engine overheats, the heating wire layer 11 does not work, and the cooling water in the temperature control water layer 12 enters the interlayer of the engine fuel supply tank 3 through the mainstream duct 2 to cool and protect the engine fuel supply tank 3. Then the cooling water in the branch pipe 21 enters the interlayer of the engine casing 4 to cool and control the temperature of the starting system 6 inside the entire engine.

[0038] Furthermore, the engine fuel supply tank 3 includes a main tank body 31, the main tank body 31 is a sandwich structure, and a feeding port is provided at the center of the main tank body 31, the main tank body 31 is evenly connected to the split oil and gas tank body 32 at the front and rear, and the main tank body 31 sandwich outer layer is connected to the mainstream conduit 2, the split oil and gas tank body 32 is connected to the crankshaft connecting rod mechanism 41, the crankshaft connecting rod mechanism 41 is provided with a crankshaft, the upper end of the crankshaft is connected to a connecting rod, the upper end of the connecting rod is connected to a piston, and three metal rings are provided on the piston, two of which are compression rings, and the lower end is provided with an oil ring, the compression ring at the upper end can prevent the smoke from falling, and the compression ring at the lower end can prevent the smoke from falling. The shrink ring can prevent the engine oil from flowing into the combustion chamber, and the oil ring plays the role of continuously supplying oil to the inner wall of the cylinder. The crankshaft converts the linear motion of the piston into rotational motion. The connecting rod connects the piston and the crankshaft. When the intake valve set in the crankshaft connecting rod mechanism 41 is opened, the piston moves downward to draw in the oil and gas mixture, and then the intake valve is closed, the piston rises, and the oil and gas mixture is compressed at high temperature. The combustion of the compressed mixture causes an explosion. The force generated by the explosion causes the piston to move downward, and then an exhaust valve is set in the crankshaft connection mechanism 41. The exhaust valve is opened, and the piston moves upward to push out the exhaust gas. The exhaust gas enters the intake and exhaust system 5 and is discharged, and the entire engine can operate normally.

[0039] Furthermore, the air inlet and outlet system 5 includes an air inlet 51, an air inlet channel tube 52 is connected to the left side of the air inlet 51, an air outlet channel tube 53 is connected to the upper left end of the air inlet channel tube 52, the diameter of the air outlet channel tube 53 is smaller than that of the air inlet channel tube 52, and the other side of the air outlet channel tube 53 is arranged at the lower end of the temperature control mechanism 1, the air inlet and outlet system 5 is connected to the crankshaft connecting mechanism 41, the air inlet 51 is connected to the left side of the air inlet channel tube 52, an air circuit is formed by utilizing the elliptical shape of the air inlet channel tube 52, and an air outlet channel tube 53 is arranged at the upper end of the air inlet channel tube, so that the entire air inlet and outlet system 5 will not cause unnecessary safety hazards due to the increase in internal pressure during the air inlet and outlet process, and then the filter cover 54 arranged can also perform the first filtration of the air to reduce the entry of dust, and the elliptical circuit can also reduce the entry of dust into the piston, causing unnecessary explosions, extending the time for inspection and maintenance, and reducing costs.

[0040] Furthermore, the engine casing 4 is a sandwich structure, and the outer layer of the engine casing 4 is a cooling and heat-insulating layer, the cooling and heat-insulating layer is connected to the branch pipe 21, and the front and rear ends of the cooling and heat-insulating layer are provided with through-thin tubes 43 on the left and right sides, and the upper ends of the through-thin tubes 43 are connected to the air inlet and outlet system 5. Water vapor will be generated in the through-thin tubes 43, and then enter the air intake channel pipe 52 to ensure the intake temperature. If the intake temperature is too low, it may cause difficulty in ignition of the mixture and slow combustion, thereby reducing engine power and increasing fuel consumption. In addition, in a low temperature environment, the engine oil may become too viscous, increasing the machine's movement resistance, and may cause fuel condensation to enter the crankcase, diluting the engine oil, affecting the lubrication effect, and aggravating parts wear.

[0041] Furthermore, the starting system 6 includes a starting motor, which is connected to a flywheel, and the center of the flywheel is connected to a rotating shaft, the rotating shaft is evenly connected to a crankshaft, and the front end of the right side of the rotating shaft is fixedly connected to an output shaft 61. The starting motor drives the flywheel to work, and the flywheel drives the rotating shaft to work. The crankshaft on the rotating shaft starts to work as the crankshaft connecting rod mechanism 41 works, thereby enabling the output shaft 61 to rotate quickly and efficiently.

[0042] Furthermore, the stable connecting tube 7 is a double-layer structure, and a thermal insulation cotton layer is provided in the outer layer of the stable connecting tube 7, the bearing is connected to the rotating shaft at the center position of the inner layer of the stable connecting tube 7, and the front and rear ends of the outer lower ends of the stable connecting tube 7 are fixedly connected to shock-absorbing feet 71, and a rubber gasket is provided at the lower end of the shock-absorbing feet 71, and the lower end of the shock-absorbing feet 71 is connected to a rectangular placement frame 72. The stable connecting tube 7 is to ensure that the direct-drive rotation of the output shaft 61 is more stable, and the thermal insulation cotton layer is used to ensure that the rotation of the output shaft 61 will not be affected by excessively cold weather.

[0043] Furthermore, a filter cover 54 is provided at the right end of the air inlet 51, an air filter is provided inside the filter cover 54, and the left side of the filter cover 54 is limitedly connected to the air intake channel tube 52, and the air intake channel tube 52 is an elliptical loop structure, which ensures that the air intake channel of the air inlet 51 is long and the structure is reasonably placed, thereby reducing the dust from entering the combustion chamber at the upper end of the piston. The setting of the filter cover 54 can greatly reduce the presence of dust in the air.

[0044] Working process: When the weather is too cold, the heating wire layer 11 starts to work so that the cooling water cup of the temperature control water layer 12 is heated and insulated through the interlayer of the engine fuel supply tank 3 to prevent the fuel from becoming sticky and increase the movement resistance of the machine. Then the water in the branch pipe 21 enters the interlayer of the engine housing 4 to prevent over-cold start. Over-cooling during the thermal cycle will cause a decrease in output power and efficiency. After long-term operation, the engine will overheat and the heating wire layer 11 will stop working. Then water vapor will be generated in the penetrating capillary 43, which will enter the intake channel pipe 52. In the cylinder, because the intake air is still undercooled, overcooling will cause the temperature of the mixed gas (or air) entering the cylinder to be too low, thereby deteriorating the quality of the combustible mixed gas, making ignition difficult or combustion slow, resulting in a decrease in engine power and increased fuel consumption. The water vapor in the combustion product is easy to condense into water and form acids with the acidic gas, which aggravates the corrosion of the engine body and parts. Therefore, water vapor is used to keep the intake channel pipe 52 warm to ensure that the incoming gas will not increase the viscosity of the lubricating oil due to being too cold, resulting in poor fluidity, causing poor lubrication, aggravating the wear of the engine parts, and increasing power consumption.

[0045] When the weather is too hot, the heating wire layer 11 does not work, and the engine is cooled normally. In addition, the air outlet channel pipe 53 is provided to facilitate heat dissipation while reducing the increase in the internal pressure of the air inlet and outlet system 5, thereby causing unnecessary safety hazards.
