The Styrian technology group AVL achieved a stage victory in the construction of its hydrogen combustion engine, which was specially tailored for use in racing: the two-liter engine achieved 410 hp on the test bench!
The AVL Racetech department has thus succeeded in proving the values calculated in the simulation of its first self-built hydrogen-powered 2-liter turbo engine on the test bench. A demonstration model of the H2-ICE racing engine was seen publicly for the first time at the “Aachen Colloquium Sustainable Mobility”. Higher liter output than usual. Unlike other hydrogen combustion engines, which are usually operated with a high excess of air (so-called lean operation, note) and therefore comparatively little power The new racing engine can generate a power level of around 150 kW per liter with only slightly lean operation. The turbo engine is therefore in a range in which production-based customer racing classes would operate today. To achieve this result, additional water is injected into the engine’s intake air via an injector. This increases the boost pressure. The evaporating liquid also has a strong cooling effect in the combustion chamber. The hoped-for values have now been confirmed on the test bench, AVL Racetech said on Tuesday: The unit achieves a specific power density in the range of 205 hp per liter (150 kW per liter). highly competitive level for motorsport. This meant that a total of 410 hp (301.7 kW) could be achieved at a speed of 6500 revolutions per minute. The torque of the unit, which was developed in cooperation with the Hungarian Humda Lab, is 500 Newton meters at 3,000 to 4,000 revolutions per minute. Looking at the values achieved, project manager Paul Kapus was proud to have “fully” confirmed them.First AVL racing engineAVL Motorsport Director Ellen Lohr said: “The goal of AVL Racetech is to lead motorsport into a sustainable future . With the development of our first racing engine developed under our own name, we have come a little closer to implementing this vision.” In addition to the Humda Lab, the Styrian M&H based in Ilz, Ventrex and Weissgerber Engineering GmbH were also involved in the project. When asked, Lohr said that the next stage in further development would be testing the new engine concept in a vehicle on the race track. AVL Racetech – formerly known as AVL Racing – has been active in all technical areas of motorsport for more than 20 years. The department works with customers in around 20 racing series worldwide in the areas of engineering, testing, simulation and production. Motorsport is used as a “platform for innovations” and the acquired know-how is to be transferred to the development of road vehicles for future generations of mobility. AVL List GmbH, with more than 10,700 employees worldwide, is, according to its own information, the largest independent company in the world Company for the development, simulation and testing of drive systems in the automotive and other industries. In 2022, the company generated sales of 1.86 billion euros.
