Summary

Degradation of the environment, followed by laws and public opinion set requirements for the automotive industry that manufacturers judge to be unrealistic. CO₂ emissions standards that have been in force since 2020 are a measure of these requirements. However, meeting them may be feasible by using the latest research achievements related to the application of active thermal layers in combustion chambers and limiting their external cooling. The paper presents the results of preliminary theoretical work carried out at the Department of Automotive Engineering of the Wroclaw University of Science and Technology in Poland together with the Engineering Office of Munich (IBS in Germany).
The assumptions of the strategy of functioning of active thermal chambers, the applied calculation model and the obtained structure of energy flows were presented. The theoretical analysis concerned the engine BMW 2.0 twin-turbo diesel engine. Improvements of nearly 40% CO₂ reduction could be simulated in theoretical investigations. Experimentally validation on series engine has to be done in next time.
