Experimental Investigation of Methanol Blend Fuel in SI Engine
Automobile have become a very important part of our modern life style. And it runs on fossil fuel. But the excessive use of fossil fuels will very soon lead to the energy crises so the future of automobile based on fossil fuels has been badly affected by two major problems. That is less availability of fuel and environmental degradation. So it is very important to found some new renewable non-polluting alternative fuels to ensure the proper and safe survival of internal combustion engines. In present study we evaluate the performance of four stroke single cylinder spark ignition engine with ratio of 10%, 20%, 30%, 40% and 60% of methanol and gasoline by volume. Performance parameters (brake thermal efficiency, brake mean effective pressure, TFC and SFC) were determined at various loads on engine with methanol blended gasoline. The comparison was made on performance of conventional SI engine with pure gasoline operation. As a result, brake thermal efficiency and brake mean effective pressure showed improved performance when compared with pure gasoline performances.
Fossil fuel is the major source for the production of energy used today. Due to the continuous rise in the cost of fossil fuel and demand of pollution free environment and clean energy has also been increasing Alternative fuel has become very noticeable and has a relevant role to play for both CI & SI engines, so it is important to reduce down dependency of gasoline as a fuel. Many research and investigation have been done focusing on using alternative fuel and minimizing the effect on fuel consumption and increasing engine performance. The aim of this review is to analyze the engine performance parameter and future hope of introducing blend of petrolmethanol, petrol with all other alcohol derivatives in varying ratios in SI engine and analyze brake torque, brake power, equivalence air fuel ratio, indicated and brake thermal efficiencies, fuel consumption, volumetric and mechanical efficiency.
Impact of Methanol-Gasoline Fuel Blend on The Fuel Consumption and Exhaust Emission of A SI Engine
The 3rd International Conference on Advanced Materials Science and Technology (ICAMST 2015) , 2016
In this study, the effect of methanol-gasoline fuel blend (M15, M30 and M50) on the fuel consumption and exhaust emission of a spark ignition engine (SI) were investigated. In the experiment, an engine four-cylinder, four stroke injection system (engine of Toyota Kijang Innova 1TR-FE) was used. Test were did to know the relation of fuel consumption and exhaust emission (CO, CO2, HC) were analyzed under the idle throttle operating condition and variable engine speed ranging from 1000 to 4000 rpm. The experimental result showed that the fuel consumption decrease with the use of methanol. It was also shown that the CO and HC emission were reduced with the increase methanol content while CO2 were increased.
Two stroke engines are extensively used in coastal regions by transportation ships and pleasure boats. Twenty to thirty percent of fuel and lubricating oil remain unburnt. This is even worse when the engine is operating at low speeds, about 40 percent of the unburnt fuel emitted directly in to the water. Lubricants plays major role in defining the percentage of exhaust pollutants because in conventional 2-stroke internal combustion engines oil is burned with gasoline or diesel. With the increase in motorization of world the need for switching to alternative fuel has increased because petroleum is a nonrenewable resource. Methanol is a great alternative fuel with low carbon content in its emission. This paper focuses on the use of methanol instead of using gasoline and diesel in 2-stroke internal combustion engine, with the use of different types of lubricants with a perception to reduce air pollution as well as reducing the consumption of gasoline by analyzing their performance.

Considering the importance of alternative fuels in IC engines for environment safety, compressed natural gas has been extensively employed in SI engines. However, scarce efforts have been made to investigate the effect of compressed natural gas on engine lubricant oil for a long duration. In this regard, a comprehensive analysis has been made on the engine performance, emissions, and lubricant oil conditions using gasoline ( G)92 and compressed natural gas at different operating conditions using reliable sampling methods. The key parameters of the engine performance like brake power and brake-specific energy consumption were investigated at 80% throttle opening within 1500–4500 range of r/min. For the sake of emission tests, speed was varied uniformly by varying the load at a constant throttle. Furthermore, the engine was run at high and low loads for lubricant oil comparison. Although compressed natural gas showed a decrease in brake-specific energy consumption (7.94%) and emission...
Investigation on Performance Characteristics of Petrol Engine Using Alternate Fuel
In the present scenario the S.I. engines being used in automotives by various manufactures are not properly suitable to out climatic condition. As our country is among tropical countries where the variation in the temperature is having very vast range i. e. from 0ºC to 48ºC in various regions of the country. Looking in to this vast varying temperature range it is very difficult to say that which temperature is most suited to operating condition of engines and gives us best performance level as for as SFC and brake power is concerned. In my work I have tried to investigate the best option to run the S.I. engine and simultaneously to maintain the emission norms. Petrol reserves are getting exhausted and it is recommended to find the alternate solution to it. In the present work the potential of methanol is being explored to serve as alternate fuel. This work is carried out with the use of petrol and methanol on a three cylinder, four stroke, petrol Maruti 800 engine connected to eddy current type dynamometer for loading was adopted to study engine power, fuel economy, engine exhaust emissions of hydrocarbon, oxides of nitrogen in the exhaust. The performance results that are reported include brake power and specific fuel consumption (SFC) as a function of engine coolant temperature; i.e. 50ºC, 60ºC, 70ºC and 80ºC with varying engine speed of 1500, 2000, 2500, rpm. Today research and development in the field of gasoline engines have to face a double challenge: on the one hand, fuel consumption has to be reduced, while on the other hand, ever more stringent emission standards have to be fulfilled. The development of engines with its complexity of in-cylinder processes requires modern development tools to exploit the full potential in order to reduce fuel consumption. There are many strategies for improving fuel economy and reducing exhaust emission. Hydrocarbon emission (HC) and carbon monoxide (CO). And finally it is concluded that no remarkable difference is recorded. With use of methanol instead of petrol the variation is marginal and can be attributed to the cycle temp and combustion efficiency. Thus methano l is recommended for use as an alternative fuel for petrol engine in coming future.
Numerical and Experimental Studies on Combustion Engines and Vehicles
The aim of this study is to develop the one-dimensional model of a four-cylinder, four-stroke, multi-point injection system SI engine and a direct injection system SI engine for predicting the effect of various fuel types on engine performances, specific fuel consumption, and emissions. Commercial software AVL BOOST was used to examine the engine characteristics for different blends of methanol and gasoline (by volume: 5% methanol [M5], 10% methanol [M10], 20% methanol [M20], 30% methanol [M30], and 50% methanol [M50]). The methanol-gasoline fuel blend results were compared to those of net gasoline fuel. The obtained results show that when methanol-gasoline fuel blends were used, engine performance such as power and torque increases and the brake-specific fuel consumption increases with increasing methanol percentage in the blended fuel.

In the present day scenario emissions associated with the exhaust of automobiles resulting in global warming is a major menace to the entire world and also detrimental to health. Here an experimental attempt has been made to know the level of variation of exhaust emissions (Carbon monoxide, Hydrocarbons, Nitrusoxides) in S.I. four cylinder engine by adding methanol in various percentages in gasoline and also by doing slight modifications with the various subsystems of the engine under different load conditions. For various percentages of methanol blends (0-15%) pertaining to performance of engine it is observed that there is an increase of octane rating of gasoline along with increase in brake thermal efficiency, indicated thermal efficiency and reduction in knocking. On the other hand exhaust emissions CO and HC are considerably decreased but CO 2 and No x simultaneously slightly increasing. It is notable that for these methanol blends combustion temperature is found to be high and exhaust gas temperature decreasing gradually.
