The manufacturer of Block Cg150 Four Stroke Cylinder will show you what is the working cycle principle of a four-cylinder four-stroke engine

Author:

The manufacturer of Block Cg150 Four Stroke Cylinder tells you that most of the internal combustion engines used in modern automobiles and industrial uses (cars, trucks, generators) are four-stroke cycles. On most four-stroke engines, the valves simply close with the return of the spring. As the engine speed increases, the time for the spring to push the valve to open and close will change, and this time change is not conducive to the performance of the engine.

One of the solutions to this problem is the Desmodromicvalve speed control system. The manufacturer of Block Cg150 Four Stroke Cylinder tells you that this system uses a mechanical device to adjust the opening and closing of the valve. This results in a higher revving engine. Some designs use additional camshafts and rockers.
The manufacturer of Block Cg150 Four Stroke Cylinder tells you that the disadvantages of this system are high complexity and high cost. Some manufacturers use it for motorcycle engine systems.
Working cycle principle:
(1) Intake stroke: the intake valve opens, the exhaust valve closes, the piston moves downward, and the mixture of gasoline and air enters the cylinder;
(2) Compression stroke: both the intake and exhaust valves are closed, the piston moves upward, and the fuel mixture is compressed;
(3) Power stroke: At the end of the compression stroke, the spark plug generates electric sparks, which burns the fuel violently and produces high-temperature and high-pressure gas. The high-temperature and high-pressure gas pushes the piston to move downward, drives the crankshaft to rotate, and works externally;
(4) Exhaust stroke: The manufacturer of Block Cg150 Four Stroke Cylinder tells you that the intake valve is closed, the exhaust valve is opened, the piston moves upward, and the exhaust gas is discharged out of the cylinder.
