How the explosion engine works

The internal combustion engine is an internal combustion engine, because the fuel burns or explodes inside the engine parts: the cylinder closed by a piston or movable piston. Which had a decisive importance in the transports, because it allowed the invention of the real automobile and the airplane. Below we explain how the explosion engine works step by step.

one

In the first time of the explosion engine is the intake or aspiration . The piston is at the top dead center and is set in motion by the action of the crankshaft. At that moment the intake valve is opened, which puts the cylinder in communication with the carburetor. As the piston descends, the pressure inside the cylinder decreases and thus a mixture of fuel and air is drawn through the intake valve, which closes when the cylinder is full.

Second time, compression of the explosion engine . Both valves, the intake and compression valves, are closed. The piston rises, and in its ascent it compresses the air and the fuel, which reaches 14th of its volume, also increases the temperature: in this way it approaches the amount of heat necessary to blow up the mixture of fuel and air .

Third time, explosion and expansion of the explosion motorcycle. The spark plug in the upper part has received an electric current and between its two points a spark ignites the compressed gases. This propagates very rapidly to the entire gaseous mass and gives rise to an explosion, which pushes the piston downwards. The connecting rod is responsible for transforming the movement from top to bottom, performed by the piston, in a rotation movement thanks to the crankshaft.

Fourth time, the exhaust of the explosion engine . The exhaust valve opens and then the piston rises again, forcing the gases out of the cylinder. This is ready to receive air and fuel again and restart the cycle. In the engine of explosion, as in the steam engine, there is an irremediable loss of calories through the exhaust; therefore, the explosion engine can not have a hundred percent performance.
