How a car diesel engine works

The diesel engine of a car differs from that of gasoline, basically, in the way of generating the process that gives rise to the movement. In this article we will explain in detail all the conditions that are necessary for the system to start. We recommend that you visit this link if you want to know how to extend the useful life of a diesel engine.

To satisfy your curiosity and have more data when choosing diesel or opt for a gasoline engine, in .com we explain how a car diesel engine works .

The ignition

For a diesel engine to ignite, the spark that is needed in gasoline engines does not occur. The key is in the ignition: the ignition of the fuel is produced because it is injected into the chamber at a very high pressure through very small holes, which causes it to spray on contact with the air in the chamber, which is also very high temperature. The result is that auto-ignition is generated, without the need for a spark.

The movement

The movement of the diesel engine begins because, due to this autoignition, the gas expansion of the fuel chamber occurs, which, in turn, causes the piston to descend. This, in turn, gives rise to the movement of the connecting rod, which transmits the dynamism to the crankshaft.

Plugs?

In the diesel engines there are spark plugs, but they do not have the same function as in the gasoline engine, but they are spark plugs. In the older diesel engines, the spark plugs are responsible for heating the combustion chambers of each cylinder before starting and also keeping them warm during startup.

However, in the newer diesel engines this preheating is not necessary, so that the spark plugs only perform a subsequent heating job, contributing to the reduction of environmental pollution by helping to avoid generating black smoke.
