Technical Background
Picture Of Ford Duratorq TDCi CarsThe British-built Ford Duratorq TDCi family features new second-generation common-rail technology from Delphi Automotive Systems, the Multec (TM) DCR1400.
This common-rail system provides extremely precise injection control using a technique called "pilot accelerometer technology". A vibration sensor mounted on the engine cylinder block detects the onset of combustion and minutely corrects the initial amount of so called "pilot" fuel down to quantities below one cubic millimetre. The result is a controlled, ultra smooth, and efficient combustion process.
The system features slim, six-hole, pressure-balanced, solenoid-actuated fuel injectors produced according to strict manufacturing tolerances far smaller than the width of a human hair. The tiny moving masses of the light and balanced control valve allow the use of an ultra-compact solenoid, located in the middle of the injector body closer to the nozzle needle than other common-rail systems.
The injector's package-efficient design has a maximum diameter of 17 mm, making it ideal design for installation in Duratorq TDCi's contemporary four-valve head.
