Working principle of diesel engine
In diesel engines, clean air is sucked into the cylinders and highly compressed there. As a result, the temperature in the cylinders rises above the temperature of the...

Measures to improve the composition of exhaust gases
To reduce the content of nitrogen oxides (NOx) in the exhaust gases, the diesel engine fuel system is equipped with an exhaust gas recirculation system (EGR system). The...

Exhaust turbocharger
The Ford Mondeo diesel engine is equipped with a turbocharger. Two separate turbocharger housings house two turbine wheels which are driven by the exhaust gases. These...

Driving in winter with a diesel engine
