170PS (125KW) ACE. TO ISO 8665

Solenoid controlled common rail injection system delivers 170ps and 36kg-m torque from the 2.2 liter i4 CRDI engine.

The common rail multiple injection features improve i4 D-series on environmental aspects by minimizing the emissions of particulates and NOx.

Designs for optimizing fuel injection and intake port, and combustion performance improved lowtemperature combustion stability through lean air-fuel rationing. This satisfies the world’s strictest exhaust emission standards.
