Regeneration of turbochargers, injectors, injection pumps, PLD for Kirovets – Kirowiec

Regeneracja turbosprężarek, wtryskiwaczy, pomp wtryskowych, PLD do Kirovets – Kirowiec

Hoffman Company specializes in fuel injection apparatus and engine supercharging. Weregenerate pumps for machines and tractors of Russian, Belarusian and Ukrainian production.

A rare vehicle, although found in heavy agriculture and forestry, sometimes a constructionvehicle is the Kirowiec (Kiroviec or Kirovets) vehicle. It is a company founded at the very beginning of the 19th century. Agricultural machinery is asmall part of the entire production of this tycoon.

Our company deals with professional regeneration of turbochargers in these vehicles. Each turbocharger is individually repaired using a low and high speed balancer. After balancing the entire turbocharger assembly goes to the test bench and there is a full performance test carried out there, as well as dynamic valve and geometry settings (in the latest systems).

In the case of injection pumps and injectors, we regenerate old injection solutions used, for example, in Kirovets T150 where there was a Russian in-line injection pump, or a distributor pump with two pressing sections that separate „three injectors per section”.

We also repair systems for the latest Kirovets models with Bosch PLD single pump systems, as well as with traditional pumps and CommonRail systems (e.g. KirowiecKirovets XTZ-243K.20). It is worth mentioning here that Mercedes and less often Volvo engines are used in new Kirovts. One such Mercedes engine model is

The repair of commonrail injectors is carried out in accordance with the highest manufacturers’ standards, using Bosch, Hartridge and Magneti Marelli devices. We work with the latest technologies, using electronic, programmable torque wrenches to mount injectors. The wrench measures not only the tightening force, but also the steering angle and tightening speed. These are very important repair points, because correct installation sets the atomizer with the right stresses and has a huge impact on the life of the injector.

We test commonrail pumps at the EPS 708 stand. We can repair various CR pump systems, e.g. Bosch CP4, CP3, Delphi, Simens-Continental and Denso systems.
