Delphi

In 2008, Delphi will bring a breakthrough diesel injection technology concept into the years that will revolutionize the competition for years: Direct Acting Piezo technology for diesel engines. The 2000 Bar Delphi Direct Acting Common Rail System uses a piezoceramic actuator to move the nozzle needle directly instead of being moved by an electro-hydraulic circuit. The extremely fast opening and closing of the needle independently of the injection pressure results in improved emissions and lower fuel consumption, while at the same time the power density and the motor torque are redefined. The maximum controllability of small pilot injections with exceptional multi-injection stability over the entire service life guarantees a first-class injection performance.
