What are the applications of gasoline engines?

Under the same power conditions, the size and quality of gasoline engines are smaller than those of diesel engines; the torque characteristics are better, the starting and acceleration performance is better, the running noise is lower, and the manufacturing cost is lower, so gasoline engines are widely used in aircraft, automobiles , speedboats, racing cars, small agricultural machinery, garden machinery and even aircraft models are widely used.

More information about gasoline engines is as follows:

1. Working principle: By burning the fuel in the cylinder, kinetic energy is generated to drive the reciprocating motion of the piston in the engine cylinder, thereby driving the connecting rod connected to the piston and the crank connected to the connecting rod to make a reciprocating circle around the center of the crankshaft movement, and output power. A gasoline engine is a spark ignition internal combustion engine that uses gasoline as fuel.

2. Composition: The gasoline engine is mainly composed of crank connecting rod mechanism, valve mechanism, driving mechanism, fuel supply system, cooling system, lubrication system, starting and ignition system. Taking the valve mechanism as an example, its function is to ensure that when the piston is in a certain position, the valve is opened and closed, so that the combustible mixture enters the cylinder and the exhaust gas is discharged from the cylinder.
