The master thesis deals with the problem of vintage carburettor-equipped cars. The thesis focuses on Weber carburettors, DCOE type, mounted on a BMW 2002 vintage car. To enable a faster and more precise carburettor setup, the thesis presents how to develop, make and use an affordable tool that optimises the carburettor setup. While the engine is running, the measuring system picks up data of the manifold absolute pressure, the spinning frequency of the engine and the oxygen ratio in the exhaust gases. The analysis and visualisation of the data, collected during the measurements, enable a suitable jetting setup, so that the air-fuel ratio gets closer to the stoichiometric ratio in the widest work range of the engine. That enables more linear power curve, as well as decreases the pollution and the fuel consumption. The system can be used on other vintage cars without any major modifications.
