A Review On Propanol As An Alternative Fuel In SI Engine

ABSTRACT INTRODUCTION The idea of adding low contents of ethanol or methanol or propylene to gasoline is not new, extending back at least to the 1970s, when oil supplies were reduced and a search for alternative energy carriers began in order to replace gasoline and diesel fuel. Originally, methanol was considered the most suitable alcohol to be supplementary to gasoline. Since methanol can be produced from natural gas at no great cost, and is quite easy to blend with gasoline, this alcohol was seen as an attractive additive. On the other hand, the used methanol in practice it is very is destructive to some materials like plastic components and metals in the fuel system. This very important and have great value of experience when ethanol came to be more commonly used as an alternative to the commercial fuels, since even ethanol can be characterized as an aggressive fluid. This research aims to study the different literature based on ethanol and propanol blends with gasoline. LITERATURE REVIEW Aman Hira et.al. [1] carried out the performance & emission characteristics on the CI engine using blends of ethanol and biodiesel with diesel. The experimental study is carried out with used of ethanol as blend in CI egine.The results of study concludes that the used of ethanol blend in CI engine consumes minimum amount of fuel. Yanju Wei et.al. [4]carried out the work for finding out effects of Methanol/Gasoline Blends on a SI Engine performance and emissions. The experimental results of study show that the engine power,torque ratio under the wide open throttle condition mainly depends on the amount of heat delivered to the engine. The addition of methanol considerably improves the brake thermal efficiency, while the methanol/gasoline ratio has a slight effect on it. Engine out CO and NOx emissions decrease with the boost of the methanol/gasoline ratio
