THE CYLINDER PRESSURE EXPERTS – COST-EFFECTIVE AND WITHOUT MECHANICAL INTERVENTION

AVL DITEST DPM 800

The visualization of pressure characteristics in the combustion chamber of an engine is a key process for fine tuning an engine or analyzing engine wear, especially at auto tuning shops, at workshops and in motorsports. By combining the AVL group’s know-how, AVL DITEST and Piezocryst have created an innovative new product. Reliable pressure checks can be performed in the engine’s combustion chamber without cooling, even at the highest engine temperatures such as occur in rallye sports. DPM 800 stands for “Dynamic Pressure Measurement” and allows you to measure the change in internal cylinder pressure over time without any modification to the engine, using a spark plug equipped with a pressure sensor. In diesel vehicles, the glow plug is replaced by a pressure sensor. The full package also includes the pressure spark plug, an amplifier, the AVL DITEST SCOPE and the AVL DSS software. Given its moderate price and ease of use, the measuring system is also used in schools and training centers for demonstrating the combustion processes in gasoline and diesel engines.
