Turbo diesel problems

In order to produce mechanical power, an internal combustion engine (ICE) needs fuel and air (oxygen). The amount of fuel injected into the engine depends on the amount of air drawn into the cylinders.

There is no point injecting too much fuel, if there is not enough air, since it will not burn (because it will lack oxygen).

Depending on the method of getting air into the cylinders, there are two main types of internal combustion engines:

• naturally aspirated (also called atmospheric engines): in which the air is drawn (sucked) into the cylinders due to the piston movement, which creates volume while moving towards the bottom dead center (BDC)
• forced induction (also called supercharged): in which the air is forced (pushed) into the cylinders by a compressor

For naturally aspirated engines, the intake air pressure (absolute) is always less than the atmospheric pressure (1.0 bar).

At idle speed, the intake air pressure is around 0.5 bar and gets close to 1.0 bar during full load (Wide Open Throttle – WOT).

For supercharged engines, the intake
