It is dynamic.Bent axle each rotation, respectively operation is primary above and below for piston, and the volume of cylinder is constantly changing from small to big, then from large to small, such as
This cycle is endlessly.It is closed with cylinder cover on the top of cylinder.Inlet valve and exhaust valve are housed on cylinder cover.Pass through inlet and outlet door
Opening and closing, which is realized, to be inflated into cylinder and is vented to outside cylinder.The opening and closing of inlet and outlet door is by camshaft actuated.Camshaft is led to by bent axle
Cross toothed belt or gear driving.
In working stroke, the gas pressure that toggle will generate after fuel combustion turns by piston, connecting rod
Become the torque of bent axle rotation；Then, 3 air inlet, compression, exhaust auxiliary strokes are completed using the inertia of flywheel.Crank connecting link
Mechanism is made of cylinder block crankshaft case group, piston connecting rod unit and 3 part of crankshaft-flywheel group.
The piston of engine will produce friction with cylinder barrel in existing technology, under the action of frictional force, make piston
Shirttail damaged, the skirt section of the piston in existing and the friction area of cylinder inner wall are big, improve energy consumption, once the skirt section of piston
It is worn, needs all to change entire piston, cause maintenance cost height.
