Company Dieselland – Open System specializes in producing diesel diagnostic equipment (diesel pump test benches and simulators for Electronically Controlled Diesel Injection Systems) for various automobile systems. Great attention is given to the development of test equipment for the Common Rail System (CDI, HDI etc.) and unit injection (UIS, UPS) system, including manufacturers such as Bosch, Delphi, Denso and Siemens. We have also experience with diesel fuel system manufacturers from the United States (Cummins, Detroit, Caterpillar). Our equipment has been tested in many diesel centers and aids the professional technicians to diagnose all aspects of fault finding on all CR systems for over ten years. Our small diagnostic center in Tartu tends to take in vehicles that have serious problems in fuel systems and equipment that could not been repaired by other diesel centers. Such challenges help us constantly upgrade and improve diagnostic equipment produced by us. Dieselland provides consulting services in the diagnosis of diesel and gasoline engines and can give useful advice not only on issues that we are specialized in, but also on other systems such as ABS, Airbag, Automatic gearbox failure etc.
