Abstract. The main concern of the automotive industry at this moment is to<br />

reduce pollutant emissions, fuel consumption, and also increasing the engine<br />

performance. Due to its excellent combustion properties hydrogen can be used as<br />

addition for the improving combustion in the gasoline-fuelled spark ignition (SI)<br />

engines. Beside experimental research thermo-gas-dynamic simulation models<br />

of spark ignition (SI) engines are one of the most effective tools for the analysis<br />

of engine performance, parametric examinations and assistance to new<br />

developments.<br />

The paper presents results of modelling thermo-gas-dynamic processes of<br />

the spark ignition engine fuelled with hydrogen in addition. The research has<br />

focused on emissions (NOx, CO, CO2), fuel consumption, and engine<br />

performance.<br />

Key words: internal combustion engine, hydrogen addition, simulation,<br />

fuel properties, performance<br />

1. Introduction<br />

During the last years SI-engines have been further improved. Engine<br />

development has focused on the reduction of tailpipe emissions, better fuel<br />

economy and higher engine performance as well as reduction of system costs.<br />

The legislation for Particulate Matter is particularly challenging, both in<br />

terms of measurements and in ensuring conformity to legislation. The restriction<br />
