Electronically Controlled Fuel Injection Systems for Medium Speed Diesel Engines

In response to 2000-2005 emissions legislation requirements for improved fuel economy at an acceptable cost, new electronically controlled fuel injection systems for medium speed engine category have been developed and released for locomotive, marine and gen-set application.

The engine classification is as follows:

• max. cylinder output 350 kW
• max. engine speed 1100 rpm
• diesel fuel quality

The solenoid valve controlled cam driven pump-line-nozzle system has the following main features:

• max. injection pressure 1800 bar
• flexible control of injection timing
• variable injection rate

The newly developed common rail system additionally includes:

• variable injection pressure
