Unit
Injector (UI) is an integrated direct fuel injection system, combining
the injector nozzle and the injection pump in a single component. The plunger
pump used is usually driven by a shared camshaft.
This injection system
is mainly fitted on heavy duty trucks (Iveco, Scania, Volvo, Renault, etc..) and
passenger cars such as VW, Audi, Seat and Skoda 1.9 TDI and 2.0 TDI and Ford
Galaxy 1.9 TDI.
The start of injection and the injected fuel quantity are
electronically controlled by the vehicles ECU (electronic control unit).
The Unit Pump system is a modular high-pressure diesel injection system, which
is similar to the Unit Injector system. The systems use an individual injection
pump mounted on the engine block for each cylinder. The fuel pumps are driven by
an extra camshaft lobe where each unit pump is connected to the injector via a
short precise length high-pressure fuel line. This type of injection system is
common for heavy duty trucks, and other industrial vehicles: Mercedes, Daf,
Scania and Deutz engines. Total Diesel Service ownes modern equipment which
guarantees precise testing and repairing for Bosch, Siemens and Delphi unit
pumps and injectors.
Total Diesel Service provides remanufactured unit
injectors and pumps, from stock, at competitive rates for a wide range of
vehicles. >> see Unit Injectors section
