More Fuel Efficient and Cleaner Diesels With Higher Injection Pressures

Denso HP Pump, injector and common rail. A diesel common rail system is the mainstream fuel injection system for diesel engines. The fuel is highly compressed by the fuel pump and stored in an accumulator called a common rail. It is then sprayed through a piezo-electric injector into the combustion chamber. Storing highly compressed fuel in the common rail, not only increases the pressure of the fuel, but also controls fuel injection pressure and timing without being affected by the engine?s rotation speed.
