Diesel principle
Clean air is sucked into the cylinders of a diesel engine and subjected to strong compression. As a result, it heats up to approximately bOOo. At this time, shortly before the piston is at top dead center, diesel fuel is injected, which ignites due to the high temperature. In this case, spark plugs are not needed.
When the engine is cold, it may happen that the temperature of the compressed air is not sufficient to ignite the diesel fuel. Then the fuel is additionally heated. For this purpose, each vortex chamber has a heating plug. In addition, the diesel engine has a hydraulic cold start accelerator, which shifts the operation of the fuel advance clutch plungers in the injection pump to the early injection position. This makes it easier to start a cold engine. As soon as the engine warms up, the accelerator is automatically turned off. Fuel is taken by a distribution injection pump directly from the fuel tank.
