In my study book diesel and petrol engines are divided into 4 assemblies and auxiliary equipment (see pictures). I find this somewhat confusing with the diesel engine. For example, in contrast to the ottomotor the assemblies are not marked fat. The 4th assembly with the diesel engine is called “fuel system with injection equipment” with the components: – fuel pump – fuel filter – high-pressure injection system (e.g. common rail system or pump nozzle-Sy The first 3 modules in the diesel engine are “motor housing”, “wheel drive” and “motor control”. The components were not named, but they are the same as in the petrol engine. Do I understand that correctly?
