The main development targets for future motorcycle and small vehicle propulsion units are the reduction of dimensions, weight, fuel consumption and pollutant emission for a considered power output. The paper presents a concept for the improvement of the thermodynamic process stages consisting on scavenging, mixture formation and combustion - as a main support for achieving the mentioned targets. The concept is exemplified by results in terms of compared indicator diagrams, specific fuel consumption and exhaust gas emissions - in base of numerical simulation and experimental analysis at the engine - respectively at the vehicle test bench.
