Selection Of

The automobile sector which is growing day to day consumes the fossil fuel more than its growth. So there is a demand for exploring new sources of fuels for existing engines. This led to the growth in bio diesels which is an alternate fuel. An alternative fuel must be technically feasible, economically competitive, environmentally acceptable, and readily available. In this project esterified Nerium oil is used as an alternate fuel. A single cylinder stationary kirloskar engine is used to compare the performance and emission characteristics between pure diesel and Nerium blends. In this project selection of suitable nerium blend and selection of optimized injection timing for the blend is done. The Nerium oil blends are in percentage of 20%, 40%, 60%, 80%, and 100% of Nerium oil to 80%, 60%, 40%, 20% & 0% of diesel. From this project it is concluded that among all nerium and diesel blends 20% of nerium and 80% of diesel blend at 30º BTDC gives better performance nearing the diesel. When comparing the emission characteristics HC, CO is reduced when compared to diesel, however NOx emission is slightly increased when compared to diesel. Hence Nerium blend can be used in existing diesel engines with minimum modification in the engine. It also describes the usage of non-edible oil to a greater extent.

This paper presents the properties and application of cashew nut shell oil as blend component for diesel in compression ignition engine. Experimental tests were carried out in a single cylinder, four stroke, direct injection, compression ignition engine fueled with cashew nut shell oil blends. During the experiments, the performance and emission characteristics of the diesel engine was analyzed and compared with the neat diesel fuel performance.

Increasing Demand

Increasing demand and rapid depletion of fossil fuels have together prompted the researchers of many countries to look for alternate renewable fuels. This study is an attempt to test the feasibility of rice bran oil as fuel in C. I. engine in its original and in its refined form. It is generally produced from rice bran which is a by-product produced during paddy processing. Its viscosity though relatively higher than diesel can be reduced by natural sedimentation process. In this attempt, the performance and emission characteristics of rice bran oil and its refined form were studied and compared with diesel by employing them as a fuel in a single cylinder, direct injection, 4.4 KW, air cooled diesel engine. The performance characteristics revealed that the brake thermal efficiency of the rice bran oil was higher than its refined form and were marginally lower than that of diesel. Emission measurements were carried out using MRU Delta 1600L gas analyzer and the soot concentration was measured with AVL smoke meter. It was found that though blends of rice bran oil with ethanolexhibited greater soot concentration characteristics than rice bran oil and diesel at all loads, it exhibited desirable characteristics for other emissions such as lower CO, HC, NOx emissions and lower exhaust gas temperatures with increasing load.
