Diesel Products

There are few components in a common rail diesel system but they are sophisticated and complex.

Injectors

We offer a full range of injectors from the conventional pintle types to the nozzle types. This component is a vital part of the fuel delivery system, poor injection will cause a loss of economy and power.

Electronic unit injectors(EUI)

Modern innovations include EUI systems such as the UIS(Unit injector system) from BOSCH and the EUP(electric unit pumps) from DELPHI

In line fuel pumps

There is a wide variety of fuel pumps from early pneumatic pumps(Bosch,CAV and Simms) through the mechanical units and on to the EDC systems such as those in the Bosch H type categories

Rotary Fuel Pumps

The long established rotary diesel fuel injector pumps require specific build and test procedures. Some of the best known units in this family derive from the CVA,DPA pump. As with in-line pumps technology has evolved from mechanical and hydraulic controls(DPC, DPCN, DPS, DO200, DP210) through to electronic systems such as the DELPHI EPIC system

Common Rail

This is now the norm in modern passenger car diesel engines. This high pressure system can operate at up to 200 bar(29000 psi). Such high pressure means that any fault must be diagnosed and rectified immediately otherwise fuel system and engine damage can occur rapidly.

The common rail system uses a pump to produce the high pressure. This fuel is led by high pressure metal pipes to the accumulator or rail. The rail is pressure controlled and sensors in the system signal a computer module(DCU). The module calculates timing and flow, it then triggers the electronic injectors to deliver the fuel in to the cylinder. There can be up to 7 injections per power stroke!

All of these are available from Waterloo
