The assessment of external and operating indexes of LPG fueled engines

This paper presents the issues related to combustion engine fueling systems using gasoline and LPG. The results of measurements carried out at the test stand enabled the analysis of the impact of alternative - LPG fueling on the external indexes of the engine, i.e. maximum values of the torque and power. Knowing the values of such parameters, with the maximum throttle opening (full-power characteristics), conclusions on engine dynamics have been drawn and compared to the traditional fueling.
