The operating cycle of an internal combustion engine

[zihadhosenjm40]

A car can be defined as a mechanical device that releases the latent energy of gasoline and, by controlling the released energy, uses it to turn the wheels. Gasoline fuel is injected into each of the engine's cylinders in turn (pictured above), where it burns. The energy released during combustion moves the piston of the cylinder. The paytm data moves down the cylinder like a fist when we put our hand through a sleeve, and through the crankshaft, with the help of a clutch mechanism, transmits energy to the gearbox.

After the gearbox, the energy of rotational motion is transferred to the drive shaft. It rotates together with the differential mechanism. And the differential not only transmits energy to the drive axles installed perpendicular to the drive shaft, but also allows the left and right wheels to rotate at different speeds if necessary. For example, when the car is moving on a turn.

During fuel intake, the piston moves down and a mixture of gasoline vapor and air is drawn into the cylinder. Then the piston rises - the mixture is compressed. A spark appears on the spark plug - the fuel mixture ignites, burns - and the energy released during combustion makes the piston move down. In the last, fourth stroke of the movement, the piston rises again and pushes out the exhaust gases through the exhaust valve.

The accelerator helps the carburetor prepare the required amount of fuel mixture at the given moment, which consists of gasoline vapors and air. This mixture is then drawn into the cylinders and ignited there by spark plugs.

Mechanism for controlling two unequal movements

In order for a car to turn smoothly, its wheels on the outside of the track must move faster and travel a greater distance than the wheels on the inside of the track. This is possible because the car has a mechanism called a differential. It is a clever set of mechanical gears with cogwheels and pinions that connect the drive shaft to the rear wheel axles so that each wheel can turn at the speed it needs.
