Research on alternative fuels for fossil fuels become prominent due to the gradual depletion of fossil fuel and global warming. Lemon Peel Oil (LPO) is an alternative biofuel produced from lemon rinds. LPO has its properties lower heating value, octane number and air/fuel ratio are similar to that of gasoline. In this study, LPO is used in SI Engine as an alternative fuel. In this study, the experimental investigation of LPO-gasoline blends for combustion, performance, and emission characteristics in an SI engine. For this work, gasoline and two different LPO-gasoline blends, 20% and 40% by volume concentration of LPO, has been prepared. The present work is investigated in the Port Fuel Injection (PFI), a four-stroke single cylinder engine. The engine is operated under various loading conditions at an equivalence ratio of one and constant speed (1500 RPM). The results of different LPO-blends are compared with the baseline gasoline under various loads for the analysis of combustion, performance and emission. For the statistical analysis, ANOVA with two-factor interaction is performed. The results of shows that LPO-gasoline blends have similar brake specific fuel consumption and brake thermal efficiency to that of gasoline. The combustion characteristics heat release rate and in-cylinder pressure mean gas pressure, of LPO-gasoline blends, have similar trends that of gasoline. The decrease in emissions of HC and CO are observed with an increase of LPO content in blends. However, with the increase of LPO content in blends, an increase in NOx emissions is observed. The results indicate that LPO is a suitable alternative fuel for gasoline SI engine.
