System Description And Functional Operation: General Description

The 2.7L direct injection diesel engine system is equipped with the latest technical advances. The on-board diagnostics incorporated in the engine control module and SKREEM are intended to assist the field technician in repairing vehicle problems by the quickest means.

The engine system incorporates a common rail fuel delivery design with exhaust emission feedback. This design utilizes electronically controlled solenoid valve type fuel injectors. Each injector is controlled individually by the ECM. Injector timing and fuel quantity are controlled by the ECM based on inputs from various sensors. The precision control of the injectors by the ECM helps to reduce the engine noise, odor and smoke.
