Engine version developing 150 kW (efficiency version)

In addition to the performance versions, the new generation of engines includes an efficiency version developing 150 kW and 400 Nm (engine code CLAB).

Differences between the efficiency and performance versions are:

• An exhaust turbocharger GT2056 optimised for lower power output
• Common rail injection system with a maximum rail pressure of 2000 bar
• Reduced hydraulic flow through the eight-hole nozzles in the piezoelectric injector

A further measure designed to increase the efficiency of the 150 kW unit is a performance-based reduction in the exhaust timing duration from 202 deg. to 176 deg., thus allowing more efficient use to be made of expansion in the cylinder. Thus, fuel consumption has been reduced still further.
