Vehicle engineering consultant Ricardo is to work with DaimlerChrysler and Swiss sensor maker Kistler to develop innovative engine management systems.

The two-year project will aim to improve internal combustion engines, reduce emissions and fuel consumption, and improve performance and driveability.

The project is supported by e1m (£650,000) from the EU and additional funding from the Swiss government.

Existing engine management systems do not directly measure the key performance characteristic: peak cylinder pressure. They generally measure inlet air temperature, inlet manifold pressure, camshaft position, and air mass to calculate cylinder pressure. Kistler has developed a low-cost sensor that can fit in the combustion chamber to measure the pressure directly.

Ricardo project manager Marc Vigar said the model describing engine behaviour is being developed.

A production system will be ready by 2001.
