Frequently Asked Questions

How does the hydrogen engine work?

We have developed 2 types of hydrogen combustion engines:

  •  The first type is the dual-fuel version. This engine can run on diesel as well as on a mixture of hydrogen and diesel. In hydrogen mode, diesel is used to ignite the hydrogen. 
  • The second type of engine can only run on hydrogen and has a spark igniter (or spark plug) to start the combustion of the hydrogen.

When the air is aspirated into the engine, hydrogen is injected under low pressure at the air inlet of the cylinders. A mixture of hydrogen and air is injected into the cylinder. In this way, hydrogen can never accumulate in the engine. By injecting (pilot) diesel, a flame is created that automatically burns all the hydrogen in the cylinder with it. Burning hydrogen generates heat and pressure which is the driving force for the engine to run.
