Studie vlivu výkonnostních úprav na změně účinnosti, měrné spotřeby a emisí u dvoutaktního spalovacího motoru

Abstract

This diploma thesis deals with the study of the effect of modifications of a two-stroke internal combustion engine, specifically the Babetta 210 moped. The aim of the thesis is to measure and evaluate the performance, consumption, emissions and efficiency of the engine before and after the engine modifications. In the beginning of the work, research is written in the area of two-stroke internal combustion engines and increasing their performance. The parameters of the original, unmodified engine are also listed. Next, a description of the performance modifications of the mentioned engine is made. This is followed by the measurement itself and its evaluation. One of the points of the work is also the design and implementation of a stationary frame on which the moped will be placed during some measurements. At the end, there is an evaluation of the set goals of the work and other possible suggestions for improving the engine.
