HOW GASOLINE ENGINE WORKS

Gasoline engine is a type of machine the most widely used primarily on light vehicles: motorcycles, and the car. Gasoline engine was created by a German engineers, Nicholas Otto.

On a gasoline engine, gasoline is burned to acquire thermal energy. This energy is further used to perform mechanical movement. The working principle of a gasoline engine, simply be described as follows: a mixture of air and gasoline from carburetor sucked up went into the cylinder, compressed by the motion of the ride the shaft, burned by a spark from the spark plugs to obtain heat energy, Which, with the burning of gases will raise the temperature and pressure in the siliinder space, so that the shaft is moving down up in the cylinder due to high pressure combustion, motion up and down the piston rod is then converted into the shaft of rotary motion of crankshaft. Through the mechanism of the valve is connected to the crankshaft setting opening valve enters the fuel valve and dumping the remains of the burning is done on a periodic basis.

On petrol engines, the combustion process occurs with the help of Sparks sparks delivered through the spark plug.

HOW GASOLINE ENGINE 2 STROKE WORKS

1. Suction and Compression Stroke

• At the top of the piston compression action occurs

• Simultaneously suction action occurs in the crank chamber or in part

bottom of the piston.

• piston moves from BDC (bottom dead point) to tma (top dead point).

• At the time of the flushing channel closed begun to do the compression stroke

in the cylinder chamber.

• At the time of opening the suction channels, air and fuel mixture will be

into the crank chamber.

2. Works and Waste Stroke

• Before the piston reaches TDC (top dead point), plugs would spark electric fire so that the mixture of air and fuel to be burned and cause thrust against the piston, so that the piston will moving from TDC (top dead point) to BDC (bottom dead point).

• Shortly after the closed suction drain and rinse well as the exhaust duct open, a mixture of air and fuel in the crank chamber will push the residual gas combustion to exhaust manifold through channel rinse.
