Abstract

Fossil fuels are the most commonly used fuels in the world, causing various types of environmental pollution due to the increase in energy consumption; the demand for renewable energy such as biofuels has increased. The aim of this study was to evaluate the performance and pollution of a four-cylinder gasoline engine with biofuels of ethanol, propanol butanol and pentanol at three different speeds of 1000, 1500 and 2000 rpm.  The results of the tests showed that adding alcoholic fuels to gasoline increases engine power. Improves engine torque. Brake specific fuel consumption of the engine with proposed fuels increases compared to pure gasoline, but this trend decreases with increasing the speed from 1000 to 2000 rpm. In terms of pollutant emissions, the amount of NOX pollutant increased with increasing engine speed in fuel combinations, but this pollutant had a lower amount compared to pure gasoline fuel. The emission of HC pollutant decreases by increasing the percentage of pentanol in fuel compounds. In addition, the amount of CO pollutant decreases greatly with the increase of engine speed from 1000 to 1500rpm and the engine speed increases from 1500 to 2000rpm. In addition, with the increase in the volume percentage of pentanol in the fuel compounds, the amount of CO increased.
