Winterthur, November 2019 – Kistler, the Swiss measurement technology expert, is adding a new product to its portfolio: the innovative HIS high-speed camera system with optical probes for visualization of combustion processes in engines. The system comprises a control unit, a high-speed camera and a borescope with integrated LED illumination. HIS helps engine developers to optimize combustion processes, with the focus on emissions and consumption.

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 optimizing their emission and consumption values. Demand for increasingly accurate measuring instruments is therefore growing – and Kistler has responded by expanding its range of products for the optical analysis of combustion processes.

High-resolution images of combustion processes

The new HIS system comprises a control unit, a 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 high-speed camera captures up to 40,000 high-resolution images per second and is equipped with an LED system for illumination. Thanks to these features, users can carry out precise investigations of gasoline direct injection and flame propagation. The high-speed camera images are captured synchronously with the combustion analysis pressure values in one control unit. All data is matched to ensure precise fine-tuning of the combustion process, resulting in optimal consumption values.

User-friendly integration of pressure sensor and light conductor

Another Kistler highlight: 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 engine applications aimed at developing high-performance compact engines with complex cylinder head geometries.

These new products from Kistler play a key part in the cost-effective development of engines with optimized consumption values and emission levels.
