Abstract
ABSTRACT This study involves the evaluation of the thermal characteristics of gasoline engines fuelled with LPG instead of gasoline fuel using the simulation software Diesel-RK. The feasibility of using LPG is investigated via parameters (combustion, performance, and emissions) at different engine speeds and compression ratios. A two-zone combustion model is used. The results revealed that the maximum pressure obtained was 82 bar for gasoline compared to 78 bar for LPG at 5000 rpm. There is a noticeable reduction in BSFC with the use of LPG relative to gasoline for all ranges of compression ratio and engine speed used. The NOx emissions were significantly reduced by 8.60% using LPG rather than gasoline. Studies conducted by different researchers validate the obtained results.
