The operating principle of the Common Rail system

The fuel pump, situated in the fuel tank, pumps diesel into the high pressure pump which is cleaned by the fuel filter.

It generates high pressure while still pumping diesel into the Common Rail. It distributes the diesel to the injectors which receives the fuel at a very high pressure.

The computerised control unit, with which it is directly connected, manages the duration and moment at which the injectors open.

What does the remanufacturing process look like?

The disassembly of the injector and the cleaning of the all its components in high temperature ultrasonic washers

Spraying test

After each completed test, we provide a report containing accurate results.

Why it’s worth remanufacturing?

Increased engine power

Restoring factory values ensures that the vehicle engine regains its original power

Reduced consumption

Damaged components in a given vehicle can have a real impact, leading to significantly higher fuel consumption.

Bigger savings

Purchasing new parts can cost up to 2-5 times more!

Free delivery

Delivery in Poland is always free.
