Modern diesel engine fuel system components, especially those in common rail fuel systems, have piezoelectric injectors. These injectors are highly precise and capable of handling extremely high pressures.
Exhaust system
The exhaust system can also be considered as one of the components of a diesel engine fuel system. All the gases produced after combustion are removed from the engine through this system. Modern diesel engines feature more advanced emission control technologies such as:
- Diesel particulate filters (DPF)
- Selective catalytic reduction (SCR) systems
The function of these technologies is to minimize harmful emissions.
Engine control unit (ECU)
Some modern diesel engines also feature electronic engine control units or ECUs. The function of ECUs is to monitor different parameters such as:
- Fuel injection timing
- Fuel pressure
- Fuel amount
The ECU is responsible for ensuring the optimal output of engine performance, fuel efficiency, and engine emissions.
