Diesel fuel injection device [Toyota Carina T170]

Cleanliness is a prerequisite for all work on a diesel engine. It is imperative to clean the union nuts of the pressure pipe before unscrewing them. The high-pressure fuel pump cannot be disassembled or repaired. and is replaced if it fails. Special tools and devices are required to adjust the high-pressure fuel pump and the adjustment should be done in a workshop. Diesel engines operate with either direct or indirect injection, that is, when the fuel is injected into the pre-chamber in the cylinder head, which is connected to the combustion chamber itself. The combustion process begins in the pre-chamber and, under the resulting pressure, fuel particles are drawn into the combustion chamber, where they are completely burned.
