The optimization of the combustion engine is one of the core competences of the Argomotive GmbH Institute for Efficient and Environmentally Compatible Drive Technologies. The pollutant emission must be reduced while the efficiency is increased at the same time. In-cylinder as well as post-engine measures are tested for this purpose. Additional current investigations are related to the subjects of: combustion research, exhaust aftertreatment, alternative drive concepts as well as simulation and computation. There are the following service modules:
