In today’s world, energy security emerged as a decisive challenge among developing economies of the world, India is one such country. Importing the colossal amount of oil to fulfill daily oil demand, uncertainty in the fuel prices, and continuous degradation of air quality thwarts the nation’s economy. To make it less severe, biofuels are observed to be promising alternatives that can overcome the issues of oil import and emission drawbacks. Biofuels seem to be an alternative to conventional fuels due to the advantage of having reduced emissions and better air quality. This paper presents an experimental investigation of biofuels Ethanol and n-Butanol in a Multipoint Fuel Injection (MPFI) Gasoline Engine. It involves the testing of different biofuel blends in a four-cylinder petrol engine to obtain the best biofuel proportion in terms of performance and emission. The analysis of the results shows that the use of biofuel blend in gasoline significantly improves the performance of an engine for ethanol blend of E5 and E10 and the n-butanol blend of B10. Further, there is a considerable decrease in emission parameters for the E5 and B10 blend of biofuel compared with all other tested blends.

在当今世界，能源安全已成为世界上发展中经济体的决定性挑战，印度就是一个这样的国家。进口大量石油以满足日常的石油需求，燃料价格的不确定性以及空气质量的持续下降阻碍了该国的经济发展。为了减轻它的严重性，人们观察到生物燃料是可以克服石油进口和排放问题的有前途的替代品。由于减少排放和改善空气质量的优势，生物燃料似乎是传统燃料的替代品。本文介绍了多点燃油喷射（MPFI）汽油发动机中生物燃料乙醇和正丁醇的实验研究。它涉及在四缸汽油发动机中测试不同的生物燃料混合物，以获得性能和排放方面最佳的生物燃料比例。结果分析表明，在汽油中使用生物燃料混合物可以显着改善E5和E10的乙醇混合物和B10的正丁醇混合物的发动机性能。此外，与所有其他测试混合物相比，E5和B10生物燃料混合物的排放参数显着降低。
