Automotive sector is one of the major contributors to air pollution and global warming due to the carbon residue and smoke opacity emission. Today, the trend of decreasing sources of petroleum fuel has led to innovation of other resources such as alternative fuel. Alternative fuel can be produced from biomass such as alcohol in which it is produced by fermentation of sugar, cane and corn. This experiment was conducted to investigate the effects of ethanol on gasoline engine performance and exhaust emissions. A four-stroke, single cylinder engine was tested by different range of ethanol volume percentages i.e. 10% (E10), 20% (E20) and 30% (E30) blended with fossil gasoline. The experiment was carried out at variations of engine speed and constant load. The engine speeds used for a constant load at 2 Nm were 2000rpm, 2500rpm and 3000rpm. From the results obtained, it shows that the brake specific fuel consumption for the blended fuel is better than gasoline fuel. Combustion efficiency of gasoline engine has improved with the use of ethanol-gasoline blends. Exhaust emissions such as CO and smoke opacity are decreased due to the presence of oxygenated properties of ethanol in blended fuel. However, emissions of CO2 are increased due to the high combustion temperature. In overall, the E20 shows the best results for all measured parameters at all engine test conditions.

Air pollution, especially in large cities around the world, is associated with serious problems both with people’s health and the environment. Over the past few years, there has been a particularly intensive demand for alternatives to fossil fuels, because when they are burned, substances that pollute the environment are released. In addition to the smoke from fuels burned for heating and harmful emissions that industrial installations release, the exhaust emissions of vehicles create a large share of the fossil fuel pollution. Alternative fuels, known as non-conventional and advanced fuels, are derived from resources other than fossil fuels. Because alcoholic fuels have several physical and propellant properties similar to those of gasoline, they can be considered as one of the alternative fuels. Alcoholic fuels or alcohol-blended fuels may be used in gasoline engines to reduce exhaust emissions. This study aimed to develop a gasoline engine model to predict the influence of different types of alcohol-blended fuels on performance and emissions. For the purpose of this study, the AVL Boost software was used to analyse characteristics of the gasoline engine when operating with different mixtures of ethanol, methanol, butanol, and gasoline (by volume). Results obtained from different fuel blends showed that when alcohol blends were used, brake power decreased and the brake specific fuel consumption increased compared to when using gasoline, and CO and HC concentrations decreased as the fuel blends percentage increased.

In-cylinder flows such as tumble and swirl have an important role on the engine combustion efficiencies and emission formations. In particular, the tumble flow, which is dominant in-cylinder flow in current high performance gasoline engines, has an important effect on the fuel consumptions and exhaust emissions under part load conditions. Therefore, it is important to know the effect of the tumble ratio on the part load performance and optimize the tumble ratio of a gasoline engine for better fuel economy and exhaust emissions. First step in optimizing a tumble flow is to measure a tumble ratio accurately. In this research the tumble flow was measured, compared and correlated using three different measurement methods: steady flow rig, 2-Dimensional PIV, and 3-Dimensional PTV. Engine dynamometer test was performed to find out the effect of the tumble ratio on the part load performance. Dynamometer test results of high tumble ratio engine showed faster combustion speed, retarded MBT timing, higher exhaust emissions, and a better lean burn combustion stability. Lean limit of the baseline engine was expanded from A/F=18:1 to A/F=21:1 by increasing a tumble ratio using MTV.
