The fuel rail supplies the injectors with fuel with minimal pressure fluctuations between individual injections.
The natural-gas injection valve injects natural gas (compressed natural gas – CNG) at system pressure into the intake manifold.
The electronically controlled unit injector is a single-cylinder injection pump with integrated injection nozzle and solenoid valve.
The unit pump injection system (UPS) injects the fuel into the engine cylinder.
With high pressure, the unit pump ensures excellent mixture preparation and combustion of fuel with specific high performance.
It is expected that the number of vehicles with compressed natural gas (CNG) powertrain systems will continue to rise in the years to come.
Diesel injection system for a maximum pressure up to 2000 bar
Suitable diesel common rail systems for all vehicle types due to modular design
The robust CRIN-LE common-rail injector injects exactly the right amount of fuel required for efficient combustion into the cylinder.
The primary advantage of the diesel common-rail system is the enormous flexibility of the injection pressure and the injection timing.
