The subject of the work presented here is to establish a setup for a 1-cylinder 4-stroke engine test bench based on an experimental setup. Two power generators, each equipped with an Otto and a diesel engine, will be used for this implementation. These are intended for the investigation of oil emissions in the exhaust gas. Oil emissions are a component of the pollutants in the exhaust. In light of increasingly stringent exhaust emission regulations, a reduction of emission particles from the oil components is to be pursued. Furthermore, a targeted reduction of these emissions can demonstrably extend the lifespan of exhaust after-treatment systems. A quadrupole mass spectrometer will be used to measure unburned lubricating oil in the exhaust gas. Initial insights for further measurements are to be drawn from these. Additionally, an indexing was conducted on the diesel generator. The focus of this work lies in the area of exhaust gas analysis as well as the feasibility and implementation of the investigation with the mass spectrometer.
