W artykule przedstawiono wyniki badań stężenia składników toksycznych spalin zarejestrowane podczas pracy silnika Wankla. Pomiary wykonano dla różnych prędkości obrotowych silnika przy zasilaniu benzyną a następnie zasilania wodorem. Porównano stężenie niespalonych węglowodorów, tlenku węgla, dwutlenku węgla oraz tlenków azotu. Wykazano wielokrotne zmniejszenie zawartości tych związków podczas zasilania wodorem.

The paper presents the research results on the concentration of toxic exhaust gas components measured upon the Wankel engine operation. The measurements were made at various engine velocities for supplying with petrol and hydrogen. The concentration of unburned hydrocarbons, carbon monoxide, carbon dioxide and nitrogen oxides was compared. For hydrogen supply the amount of these compounds has been proven to be reduced significantly.

The results of the investigations of the post and exploitation emissions of the harmful components of the fumes of engines from ZS were introduced in the work. Obtained results were subjected to a statistical study according to new computer procedures. Qualitative and quantitative reports were established for the level and kind of emission in reference to the changes of the state of studied engines.

The results of the investigations of the post and exploitation emissions of the harmful components of the fumes of engines from CI were introduced In the work. Obtained results were subjected to a statistical study according to new computer procedures. Qualitative and quantitative reports were established for the level and kind of emission in reference to the changes of the state of studied engines. The need for detailed analysis ofphenomena changes of state destruction of the examined engines, with a vast number of measuring data, requires the use of specialized methods of statistical concluding. The presented results were submitted to statistical analysis, where the methods OPTIMUM and AVD were used, as well as correlation and regression methods. It gave the possibility of quality and quantity comparison of results of fumes contents from stationary tests and exploitation researches. The results of this research allow a model (mathematical relations) determination of relations between smoking and the quantity of toxic fume components of a high-pressure engine. The performed tests and analyses in his work's researches indicate tothe conclusions: in the engine of self-acting ignition (CI) the emission of carbon oxide (CO), hydrocarbons (HC) and smoking are considerable, especially during start-up and engine warming; along with the decrease of environment temperature, the emission of CO, HC and smoking increase, whilst the quantity of NOx goes down, providing premises confirming the specified regulations of forming dangers on the side of engine fumes emission; the phases of start-up and warming up of the CI engine are characterized by increased fuel usage and increased emission of carbon oxide - CO, giving information and sensitising vehicle users to these harmful for the engine working conditions, the influence of environment temperature on the emission and smoking of fumes during hot start-ups is weaker than during cold start-ups.
