How Gasoline Engine Work

                                                            

This Animation picture shows how the gasoline motor works

1.  Piston at the top, Suction Stroke.

   Intake valve is open,piston moves down while sucking a mixture of fuel and air    into the cylinder cylinder filled with a mixture of fuel (in this case gasoline) and air.when the piston has reached the lowest position, the cylinder completely filled with a mixture of fuel and air.Suction step has been completed.

2. Compression Stroke

     Intake valve is closed, the piston moves upward by pressing the filling in the cylinder.

3. Ignition
  moment before the piston reached the highest point(top dead point), the contents of the cylinder is ignited by the fire from the spark plug.

4. Work steps, explosions that push the piston down with great force. Shortly before the piston reached the lowest point (bottom dead point) exhaust valveopens. Then discard step, the piston moves upward and pressing the gas that was burned out through the exhaust valve. The whole process then repeats, starting with a suction step. Because with four piston step occurs one time step of work, then the motor is called a four-stroke motor or a motor four steps

On top of each cylinder, we see two valves, one of thevalves is called the intake valve, which again calledan exhaust valve.

Piston moves up and down in cylinders.

One end of the piston rod is connected to the piston, while the other one ends connected to the crankshaft.Installation is set such that the ascending and descending motion of the piston is converted torotary motion of the crankshaft.
