Abstract: This paper is focused on the systems of fuel maps and pre-ignition maps as well as on the possibilities how to reduce emissions by tuning of these maps. The experimental research was realised using a single-cylinder small-volume piston combustion engine installed in the experimental vehicle, which was specified for the international competition Shell Eco-marathon. The main purpose of the performed research and development activities was a minimisation of the fuel consumption and reduction of the gaseous emissions. There were achieved significant positive results in this way, namely an improvement of the whole combustion process and increasing of the applied fuel efficiency by tuning of the fuel maps and pre-ignition maps. Very good results obtained by us at the international competition Shell Eco-marathon 2017 in London confirmed the above-mentioned achievements.
