E.U.I. (Electronic Unit Injectors)
EUI stands for Electronic Unit Injector, and was designed primarily for trucks and it was adopted by Land Rover and VW for passenger cars. Because an EUI can only be electronically controlled when the fuel cavity is pressurised from the camshaft lobe. As Co2 emissions are being further restricted common rail had to be adopted, to continually improve emissions.
The use of Electronic Unit Injectors has diminished over time as common rail has become the system of choice for most vehicle manufacturers particularly as emissions have been under so much scrutiny in the automotive world. However, some manufacturers such as Scania and Volvo still use EUI for their trucks and heavy commercial vehicle.
Darwen Diesels stock parts for EUI, as well as exchange units and we test and report for EUI engines.
If we don’t have stock, we are happy to repair customer units in house. We will also try for a next day service, but this is not always possible depending on the volume of work and access to spare parts.
