Hydrogen Injection
Currently we are investigating the effect of hydrogen injection into the engines we apply. With increased performance, we achieved lower emission values.


Dual Fuel System
The Dual Fuel Controller is a system to control the pilot injection which has been developed in our company. It is used for the electronic control of the gas filling in diesel/ gas engines with continuous rotational speed. By the application of this system, the dynamic of the unit remains steady, especially in the event of load steps.
