How Does an Internal Combustion Engine Work


We aren’t all mechanically minded, and for many, what goes on inside an engine is a bit of a mystery. If you want to understand your car better, then start with reviewing the principles of an internal combustion engine. A typical engine would have 4 cylinders, either in-line, or in a V-shape, and these would be pushed up and down by a series of compression, ignition and release. If this is done in harmony, the result is a crankshaft that is spinning very fast, and this forms the basis of the engines power.

The Drivetrain

How does the power generated by the engine, get to the wheels? The answer is, via a gearbox and a differential, and if your gearbox needs looking at, there is affordable reconditioned Transmission in Romford, which will restore the power delivery to how it should be. Automatic gearboxes are very popular now, as they reduce the number of tasks the driver has to complete, and such is the development of the mesh gearbox, the result is a very smooth gear change, both up and down.

Mixture of Fuel and Air

In order for the engine to run at peak performance, it must burn a mixture of fuel and air, and the system that controls this is called carburation. All engines have a carburation system fitted, which finely controls the mixture of fuel and oxygen that enters the cylinders.

Putting your foot on the accelerator allows more fuel and air into the system, which produces more power, and should the mixture be incorrect, the engine will either stutter or lose power.
