Hydrogen cars represent a viable alternative to electric cars provided that there is the necessary infrastructure for users to refuel, and above all that the hydrogen is green. For racing cars, infrastructure isn’t much of an issue, but hydrogen engines generally lack power. The Austrian manufacturer AVL Racetech has just developed a prototype hydrogen engine which might enable motorsport to go zero carbon.
This prototype is a 2-liter engine which managed to develop a power of 410 horsepower (302 kW), or therefore 205 horsepower per liter, at 6,500 revolutions per minute. AVL Racetech indicates a torque of 500 Nm between 3,000 and 4,000 rpm.
Stoichiometric combustion
The engine uses an intelligent water injection system to boost power. Water is added to the air inlet, which prevents premature combustion. The mixture ratio (air/fuel) is 1, meaning that the engine does not operate in a lean mixture but in stoichiometric combustion.
In creating this engine, AVL aimed to achieve a torque of 500 Nm and a power of 300 kW so that it might be competitive in a racing car. “ AVL Racetech’s goal is to lead motorsport towards a sustainable future. With the development of the first racing engine developed under our own name, we have taken another step towards realizing this vision “, said Ellen Lohr, motorsport director at AVL. The next step will be to test the engine in a car on a race track.
