The included angle between one side of the conical bottom section of the combustion working cylinder 4 and the horizontal plane is beta, and the beta is 45-60 degrees.
The working mode and principle are as follows:
the first step is as follows: the electric starter 1 rotates to drive the crankshaft 6 to move, the first crankshaft connecting rod 7 rises, air is sucked into the first air cylinder 2 and then compressed, and the compressed air is discharged into the second air cylinder 3 to circulate in a reciprocating mode.
The second step is that: when the first cylinder 2 starts to compress, the second cylinder 3 starts to intake air, the one-way valve enables the air in the second cylinder 3 not to flow back, when the second cylinder 3 starts to intake air, the piston of the second crankshaft connecting rod 8 rises, when the second cylinder starts to compress, the piston of the second crankshaft connecting rod 8 descends, the stop valve on the air outlet pipeline of the second cylinder 3 is opened, the compressed air is sent into the combustion acting cylinder 4, the piston type oil transfer pump sprays oil into the combustion acting cylinder 4 through an oil nozzle, and compression ignition and spark plug ignition are carried out simultaneously;
when the piston in the combustion working cylinder 4 starts to ascend to work, the stop valve on the gas outlet pipeline of the second cylinder 3 is closed when the piston rod of the second crankshaft connecting rod 8 ascends, the second cylinder 3 starts to absorb gas to reciprocate circularly, when the third crankshaft connecting rod 9 ascends to the highest position, the stop valve on the gas outlet pipeline of the combustion working cylinder 4 is opened, the third crankshaft connecting rod 9 descends to press tail gas out of the combustion working cylinder 4, and when the third crankshaft connecting rod 9 moves to the lowest position, the stop valve on the gas outlet pipeline of the combustion working cylinder 4 is closed, and oil is sprayed again to ignite. When the quality of gasoline or diesel oil is poor, the spark plug plays a role of auxiliary ignition.
The high-pressure gas of the second cylinder 3 enters the combustion working cylinder 4, and is ignited to combust and work while the gas is admitted,
due to the angle difference and the time difference, when the piston in the second cylinder 3 is pressed down, the piston in the combustion working cylinder 4 starts to move upwards to have a certain space, and simultaneously air is compressed to the combustion working cylinder 4 to perform combustion working,
the bottom of the combustion working cylinder 4 is conical. The three directions work simultaneously, the heat work conversion rate is high, and the temperature of the cylinder is reduced, so that a cooling system is omitted.
