4.5.9. Common Rail high Pressure Pump (MPROP)ΒΆ

Description

The Common Rail high Pressure Pump is a 2-cylinder radial plunger high pressure pump. It creates the system pressures required by the Common Rail Injection System for all the operating conditions of the engine. The governing of the system pressure is in the integrated fuel Metering Unit.
