Energy demand increases with growth of population and industrialization in the world. Most of the energy is consumed for transportation of goods and passengers. Most of the vehicles are currently running with conventional fossil fuels and this leads to depletion of these fuels within a few years as well as the increase in environmental pollution levels. It is required to develop alternatives which save fuel for future generation and reduce environmental pollution and global warming. One of the alternatives is to produce biodiesel from renewable source to meet the energy demand. In the present work, Mahua oil methyl ester (MOME) is developed by transesterification and blends are prepared (B0, B25, B50, & B100) with diesel to investigate optimal injection pressure in four stroke C.I engine. The optimal injection pressure and blend are found to be B25 and 240 bar respectively from the experimental results.
: The population explosion in India is causing heavy consumption of energy resources. Most of the transportation sector is based on diesel as fuel. In this regard, it is high time for the search of renewable alternative fuels to reduce the dependency of oil imports. The usage of fossil fuels is also causing environment pollution. To minimize the pollution, an alternative to diesel is found to be non edible Mahua oil. In the present work, experiments were carried out on Mahua oil methyl ester (MOME) fuel and evaluated its performance at different injection pressures ranging from 190 to 220bar with the increment of 10 bar. The effect of blending of MOME with diesel at different injection pressures were studied experimentally to evaluate the brake thermal efficiency, brake specific energy consumption (BSEC), carbon monoxide (CO), and unburnt hydrocarbon (HC) emissions. It was observed from experimental results that 20% MOME (B20) have higher thermal efficiency at 190 bar compared with pure diesel and also HC and CO emissions were reduced.
There is rapid depletion of diesel resources due to increased demand of diesel in the fields of agriculture, power production and transportation. Use of biodiesel can help reduce the dependability on diesel. In this study, biodiesel is prepared through the process of transesterification of mahua oil. Experiments are conducted on single cylinder internal combustion (IC) engine at different loads, compression ratios and blends of biodiesel. Experimental results viz., brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), volumetric efficiency (VE) and mechanical efficiency (ME) are calculated. Experimental results are analyzed using response surface methodology to identify significant parameters for each response and mathematical models are developed. A multi response optimization technique is used to optimize the parameters for minimum BSFC and maximum BTE, VE and ME. Optimum process parameters are found as 3.0142 KW of load, 19.79 of compression ratio and 20% of blends.
