A fuel engine according to claim 6, further comprising a first link and a first curved bar, one end of the first link is connected to the first piston, and the other end is hingedly connected to the first curved bar, a curved rod drive is connected to the first transmission member; further comprising a second connecting rod and a second curved rod, one end of the second connecting rod is connected to the second piston, and the other end is hingedly connected to the second curved rod, and the second curved rod is connected to the second curved rod Two transmission parts.
A driving device for a fuel engine according to claim 6, wherein the first transmission member and the second transmission member are respectively located on the left and right sides of the main shaft, and the rotation of the first transmission member and the second transmission member The same direction.
A fuel engine according to claim 5, wherein said 5N driving means, N is a natural number, and may be 1, 2, 3.
A method of operating a fuel engine according to claim 5, characterized in that said master cylinder and said master cylinder have five strokes respectively: intake, compression, work, pause and exhaust;

Step 10: When the master cylinder is in the intake stroke, the two-way valve is closed, and the first piston moves from the top dead center of the master cylinder to the bottom dead center to drive the first transmission member to move the spindle, and the air enters through the first air inlet. In the main cylinder, fuel enters the main cylinder through the injector, and a mixed fuel of fuel and air is formed in the main cylinder. At the same time, the auxiliary cylinder is in the exhaust stroke, and the second piston is from the bottom dead center of the secondary cylinder. Moving to the top dead center and discharging the gas in the auxiliary cylinder through the second exhaust port, and the second piston drives the second transmission member to move to rotate the main shaft;

Step 20, the master cylinder enters the compression stroke from the intake stroke, the two-way valve is closed, the first piston moves from the bottom dead center of the master cylinder to the top dead center to compress the mixed gas, and the first piston drives the first transmission member to move The spindle rotates, at the same time, the secondary cylinder enters the intake stroke from the exhaust stroke, the second piston moves from the top dead center of the secondary cylinder to the bottom dead center, the air enters the secondary cylinder through the second intake port, and the second The piston drives the second transmission member to move to rotate the main shaft;

Step 30, the master cylinder enters the power stroke from the compression stroke, the two-way valve opens, and the mixed gas is ignited by the spark plug, and the first piston moves from the top dead center of the master cylinder to the bottom dead center to make the master cylinder work, and drives the first transmission member to move. In order to rotate the main shaft, at the same time, the auxiliary cylinder enters the compression stroke from the intake stroke, the second piston moves from the bottom dead center of the secondary cylinder to the top dead center, and the air in the secondary cylinder is pressurized to the main cylinder through the two-way valve. And the second piston drives the second transmission member to move to rotate the main shaft;

In step 40, the master cylinder enters the pause stroke from the power stroke, the two-way valve opens, the first piston stops at the bottom dead center of the master cylinder, and the first transmission member also stops moving. At the same time, the secondary cylinder enters the power stroke from the compression stroke. The remaining gas after the combustion of the mixed gas enters the auxiliary cylinder through the two-way valve to drive the second piston to move from the top dead center of the secondary cylinder to the bottom dead center to make the secondary cylinder work, and the second piston drives the second transmission member to move Spindle rotation;

Step 50, the master cylinder enters the exhaust stroke from the pause stroke, the two-way valve is closed, and the first piston moves from the bottom dead center of the master cylinder to the top dead center to discharge the remaining gas in the master cylinder through the first exhaust port, and the first a piston drives the first transmission member to move to rotate the main shaft. At the same time, the auxiliary cylinder enters the suspension stroke from the power stroke, the second piston stops at the bottom dead center of the auxiliary cylinder, and the second transmission member also stops moving;

In step 60, the master cylinder enters the intake stroke from the exhaust stroke, and the above steps are repeated.
