Low temperature combustion (LTC) engines offer the possibility to reduce CO2 emissions compared to conventional engines while achieving low levels of pollution emissions. The LTC engines are characterized by a homogenous charge of fuel and air which is selfignited. A challenge for technial realization of these engines is actually the process control.The combustion has to be controlled in such a way that characteristic values as the load and the time point of combustion are maintained.

The process is characterized by a multiple-input multiple-output, nonlinear process behavior. At the same time the process is highly sensitive to ambient conditions, e.g. intake air temperature. For this reason recent research focusses on modelbased predictive control to solve the arising problems. The talk will cover the state-of-art LTC control and will give an outlook on future multiscale control.
