HIS high-speed camera system from Kistler

Electrified propulsion is set to gain ground in the coming years. Nevertheless, a large percentage of vehicles delivered by manufacturers will still be equipped with combustion engines, so developers are continuing to focus on optimising their emission and consumption values.

High-resolution images of combustion processes

The new HIS system comprises a control unit, high-speed camera and a borescope with integrated LED illumination. This innovative system allows detailed investigations of processes in engine cylinders, so users can examine phenomena such as the injection process, soot formation and flame propagation.

The camera captures up to 40,000 images per second and is equipped with an LED system for illumination allowing users to carry out precise investigations of gasoline direct injection and flame propagation.

Integration of pressure sensor and light conductor

The cylinder pressure sensor and the optical waveguide are integrated in one spark plug. The plug is screwed directly into the engine with no need for an additional mounting bore. The system is both user-friendly and rugged, making it ideal for modern applications aimed at developing high-performance compact engines with complex cylinder head geometries.
