Kistler successfully tests cylinder pressure sensors in hydrogen combustion engines

Winterthur, March 2024 - Kistler's existing range of cylinder pressure sensors has been successfully tested for resilience when used in hydrogen internal combustion engines. As of now, customers undertaking research and development work in this field of technology can put their trust in the proven precision and reliability of sensor technology from Kistler.

The quality and precision of Kistler's sensors have earned an industry-wide reputation for research and development in the combustion analysis segment. Cylinder pressure sensors used in hydrogen-powered combustion engines must withstand the exceptional conditions to which they are exposed in the hydrogen-air mix. Hydrogen can cause materials to become brittle, with potentially negative effects on measurement results and sensor durability. Kistler has conducted numerous series of tests to verify that its product portfolio is suitable for hydrogen applications. The results proved to be positive – so as of now, Kistler's cylinder pressure sensors are appropriate and optimal for use in hydrogen internal combustion engine research and development.

H2 engines – the low-emission combustion technology

The technology of the hydrogen internal combustion engine is not new, but it has taken a long time for research in this area to reach its current state. For future vehicle powertrains, different technical approaches will coexist or are combined – and the hydrogen internal combustion engine will find its place in this context. To undertake their work, engine development engineers rely on trustworthy measurement results – which Kistler's renowned piezoelectric cylinder pressure sensors are proven to deliver.

A proven and tested hydrogen-resistant portfolio

Engineers and scientists engaged in research and development work on hydrogen internal combustion engines can now take advantage of this familiar and extensive range of sensors for cylinder pressure measurements. As always with Kistler, the focus here too is on precision, reliability, efficiency and durability. By helping to ensure the success of this technology, Kistler is also playing a key part in achieving climate neutrality.
