CombiFuel® covers both diesel and petrol engines. The functionality of CombiFuel® differs according to the respective engine concept.
The operation of CombiFuel ® in a diesel engine is based on a trivalent approach. This means that the engine uses three fuels for the combustion. Specifically, these are hydrogen (about 10%), liquified petroleum gas (about 60%) and diesel (about 30%). A residual amount of diesel is necessary because of the self-ignition concept of the base engine.
For the petrol engine, CombiFuel® is based on a bivalent approach, where hydrogen (about 10%) and LPG (about 90%) are used.
The groundbreaking results in terms of emission reduction and fuel cost savings are realized due to the application of an optimal fuel mix and the perfect interaction between engine components and electronics. CombiFuel® forms a perfect symbiosis with the base vehicle. For the driver, there are no restrictions or compromises in daily use.
It just has to be regarded that a second tank for the liquefied gas is installed in the vehicle. The user does not need to fuel hydrogen, it is directly gained by an integrated fuel cell.
The use of liquefied petroleum gas and hydrogen, compared to diesel / petrol will lead to an elimination of the majority of emissions due to the ecologically significant better attributes. In addition, the new fuel mix allows optimal combustion and thus increased engine efficiency.
The significant reduction in fuel costs results from optimized fuel consumption and enourmously lower fuel costs.
