• Common-rail diesel technology uses a high-pressure pump which constantly maintains the fuel at ialection pressure in a single ('common') fuel rail above the cylinder head. A central processing unit controls the fuel injectors.
'Second-generation' systems inject the fuel at even higher pressure. Raising the injection pressure, says Ford, results in higher engine output, improved torque, better fuel efficiency, reduced emissions and lower noise levels.
The Duratorq TDCi incorporates second-generation common-rail technology from Delphi Automotive Systems—the MuHee DCR1400. This generates 1,400bar of injection pressure and features slim, six-hole pressure-balanced, solenoid-actu ated fuel injectors. A combustion feedback system allows the engine management system to analyse the quality Of combustion and constantly adjust the amount of fuel being injected to suit changing driving conditions and ensure the system is correctly calibrated. All of which is claimed to result in a precisely controlled, smooth and efficient combustion process.
