--This research is aimed to investigate experimentally the performance and exhaust emission characteristics of a direct injection (DI) diesel engine when fuelled with blends of conventional diesel fuel and ethanol, blends of rice bran methyl ester with ethanol, blends of diesel and rice bran methyl ester over the entire range of load on the engine. The experimental results showed that the highe...

Compression Ignition (CI) engines are widely used for transportation, agriculture, power generation and industrial applications. The conventional fuel for CI engine is petro diesel. Among the countries in the world, India is one of the largest consumers of petro diesel fuel. Indian economy is very much dependant on the consumption of petro diesel. Brake thermal efficiency, brake specific fuel c...

Use of an Engine Cycle Simulation to Study a Biodiesel Fueled Engine. (August 2009) Junnian Zheng, B.A., Shanghai Jiaotong University Chair of Advisory Committee: Dr. Jerald A. Caton Based on the GT-Power software, an engine cycle simulation for a biodiesel fueled direct injection compression ignition engine was developed and used to study its performance and emission characteristics. The major...

Experimental test are carried out on a semi-heavy duty Motorsazan MT4.244 agricultural engine at various loads in order to evaluate performance and emissions of DI diesel engine using the blends of diesel fuel with 5%, 10%,15%,20% , 30%(by volume) Castor oil and pure diesel fuel separately. The result show that maximum decreasing of PM emission is 73.2% and is observed in B15 at 50%load and the...

this research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and nox in di diesel engines. since the most important engine design parameters, includi...

There are concerns that biodiesel feedstock may compete with food supply in the long term, if the raw materials are vegetable virgin oils only. Therefore, throughout the world, large amounts of non-edible oil plants are available in nature. In this paper, experimental study has been carried out to analyze engine performance and emission characteristics for direct injection diesel engine using b...

In this study, mustard biodiesel (B100) was produced from low quality crude mustard oil and tested in a four-cylinder, direct-injection, diesel engine to investigate the combustion, performance and emission characteristics of the engine at different engine speeds and full load conditions. Biodiesel and its blends showed increased peak cylinder pressure and reduced ignition delay when compared t...

Alternative fuels have received much attention due to the depletion of world petroleum reserves and increased environmental concerns. Thus processed form of vegetable oil (Biodiesel) offers attractive alternative fuels to compression ignition engines. The present work investigates the engine performance parameters and emissions characteristics for direct injection diesel engine using coconut bi...

Within the depleting resources of fossil fuels and the increase in their price, in the recent past a lot of interest has been given to the use of plant oil specially the non-edible oil and its ester (biodiesel). Although the use of biodiesel in place of diesel has resulted in much lesser tail pipe emission, a substantial increase of NOx is reported by several researchers. It may be due to low c...
