Direct acting diesel common rail Delphi Power Train
An advanced light duty diesel fuel injection system that features a "breakthrough" injection technology. Delphi's Direct Acting Diesel Common Rail System's patented direct acting fuel injection concept uses a piezo-ceramic actuator to operate the injector needle valve directly to eliminate the need for a servo-hydraulic circuit. The technology enables the injector to spray fuel into the combustion chamber faster, with greater accuracy and at both higher pressures (up to 2000 bar) and with greater pressure efficiencies.
The system also eliminates the need for a return flow, thus all the fuel is injected and no fuel is wasted. This unique design distinguishes the system from competitive designs.
The system will help manufacturers of passenger cars and light duty trucks meet more stringent emissions standards for CO2, including Euro 6 and U.S. Tier II, Bin 5. And, it provides more sophisticated combustion control and includes greater use of electronics to balance emissions control, improved fuel economy and better performance.
