【 摘 要 】
In the last years the interest on reducing harmful pollutant emissions of a passenger car engine has been greatly increased either because the number of cars increased or because the cities growth rate became very fast. The interest in improving driveability and the comfort of the passengers also increased. This can be achieved by reducing engine vibrations and improving smooth engine functioning. A viable solution for the diesel engine is fuelling with alternative fuels and in special with Liquefied Petroleum Gas. The advantage of LPG is that this fuel is an economical solution to protect the environment because its components are light hydrocarbons, without sulphur and with a number of carbon atoms less than the diesel fuel. The paper presents experimental investigations results of a car diesel engine fuelled with diesel fuel and liquefied petroleum gas. Also experimental investigations results on cyclic variability are presented. The engine used for investigations is a turbocharged 1.5 l diesel engine which and the investigated regimen was 2000 rpm and 70% engine load. The LPG fuelling led to a decrease in pollutant emissions level and to an increase in the smooth engine running, evaluated by the variability coefficient.
