Abstract
The results of investigations of SI engine fuelled by means of injection of liquid propane-butane and equipped with storing catalytic converter have been presented in article. Application of the storing catalytic converter and an adequate sequence of values of air excess number provided the advantageous ecological properties of the investigated engine. The engine was fed with the lean mixture of propane-butane and air with periodical enrichment of the mixture in order to regeneration of catalytic converter. This enabled to increase the overall engine efficiency of about 4÷6% as well as to achieve the good efficiency of the exhaust gas toxic components conversion.
