Performance Characteristics of Spark Ignition Engine Using Ethanol as Fuel at Different Operating Conditions

The present study converses the usability of ethanol as a clean and green renewable alternative fuel for spark ignition engine. The study emphasizes not only on the inherent properties of ethanol as a fuel but also elaborately reviews about the performance characteristics of the engine considering the effects of different important parameters like cyclic variability, ignition timing, internal cylinder pressure. The study reveals the physical understanding of the engine performance characteristics under different operating conditions. In this paper, the performance analysis carried out by different researchers from their experimental and theoretical results has been presented in brief. The review of the investigation reports found in the literature reveals that the cyclic variability, ignition timing, internal cylinder pressure have a great role on engine performance with ethanol as a blended fuel with gasoline.
