Hydrogen is ideal as a fuel for internal combustion engines. Compared to fuel cells, a combustion engine is more robust and cheaper than a fuel cell, and there are other clear advantages, especially for heavy vehicles. H2 engines have been a strategic research focus at FVT for almost 20 years.

The electrification of conventional drives offers great potential for CO2 reduction. Electrification can mean a lot, from a simple heating catalytic converter to a fully hybrid powertrain. While the latter is particularly useful and widespread in gasoline engines, the diesel engine mainly can make use from the aforementioned micro-hybridization which promises great potential, but also requires research.

The engine process is the thermodynamic process around the actual energy conversion in the internal combustion engine. This includes the high-pressure process, the gas exchange, but also the supercharging. The process is therefore the core of every engine, and even after 150 years of development, there is sufficient need for research.

Still, most internal combustion engines are powered by gasoline or diesel. Even within these two groups, there is a wide range of fuel properties that can sometimes be used to improve combustion. Fuels have been and are being intensively studied at FVT.

In addition to gasoline and diesel, other energy sources are also ideal for combustion in an engine. These include, for example, natural gas, hydrogen and mixtures thereof. The application of such fuels offers potential, but also presents significant challenges. FVT focuses on combustion process development for alternative fuels.
