Kistler introduces new cylinder pressure sensor for R&D in the field of high-performance combustion engines


Winterthur, February 2025 - Research and development in the field of high-performance combustion engines relies on cylinder pressure sensors that can withstand high peak pressures while providing the best possible accuracy and signal quality. Pre-ignition or heavy knocking are typical characteristics during the development of motorsport or hydrogen combustion engines. These conditions are highly demanding for the robustness of the cylinder pressure sensors. With the piezoelectric cylinder pressure sensor 6054CU20, Kistler offers a model for engine development that outperforms the previous variants of highly robust pressure sensors in terms of measurement accuracy and has an overload resistance of up to 500 bar.

When developing the new cylinder pressure sensor 6054CU20, the focus was on maximum accuracy with significantly increased overload resistance. The sensor Type 6054C, which is already established on the market and is considered to be the most precise in the M5x0.5 design, was used as the base for this development. With the piezoelectric cylinder pressure sensor 6054CU20, Kistler successfully combined outstanding measurement accuracy with a level of robustness, that was up to today only available in less precise models. 

The cylinder pressure sensor offers maximum precision when measuring high-performance combustion engines in extreme conditions.

The cylinder pressure sensor 6054CU20 for combustion analysis in high-performance engines, such as those used in motorsports, combines high-precision measurements with the greatest possible robustness. It complements the family of M5x0.5 cylinder pressure sensors from Kistler.

High-performance combustion engines require high-performance sensor technology

For combustion analysis, the accuracy and reproducibility of thermodynamic metrics are essential to increase engine performance, reduce emissions or extend service life. The new cylinder pressure sensor 6054CU20 from Kistler, which is also suitable for use in hydrogen combustion engines, covers the challenges in the development of high-performance combustion engines with impressive accuracy and overload resistance:

  • Large measuring range up to 400 bar; increased overload pressure limit up to 500 bar 
  • High sensitivity with 15.5 pC/bar 
  • Excellent linearity of 0.3% 
  • Low thermal sensitivity change of max. 1% between 23°C and 350°C

Cylinder pressure sensors from Kistler – a large family of sensors for almost every application

With the new cylinder pressure sensor 6054CU20 Kistler expands its range with a model that is specifically designed to meet the requirements of high-performance combustion engines. This piezoelectric pressure sensor extends the family of the 6054C series and offers  the advantage, that  the measurement results follow the known pattern thanks to identical basic properties and the same mounting tools can be used. 

Kistler Group customers can rely on the proven quality and precision. You enjoy the advantages of a family-run company that focuses on its core competencies, responds flexibly and quickly to customer needs, and embodies continuity.
