Abstract

Vegetable oils are the only fuels, can be substituted as alternative to overcome the shortage in developing countries. Using non-edible oil like crude jatropha as alternative, waste land can be effectively cultivated and employment can be improved. Experiments were Initiated on semi adiabatic diesel engine with super charging air through the intake manifold using crude jatropha oil with varied injection pressure and varied injection timing to study the performance of the engine. Tests were also conducted using diesel fuel in diesel engine and engine with high grade heat rejection combustion chamber at recommended injection timing at 270bTDC with super charging air using crude jatropha oil. Improvement in performance was found with super charging when comparing with natural aspiration.

Highlights

Vegetable oils are the only fuels, can be substituted as alternative to overcome the shortage in developing countries
Vegetable Oils are being considered as an important alternative for diesel due their properties are near to diesel fuels
Fatty acids presence in the increases the exhaust emissions from the engine. Few researchers conducted their experiments on single cylinder, four stroke, water cooled diesel engine with direct injection diesel engine with 3.68 kw, 1500rpm and 16:1 compression ratio with varied injection pressure and varied injection timing using vegetable oil

Summary

METHODOLOGY

Jatroha oil is the suitable to replace the diesel fuel. It will be called with different names moglaerand, beghierand, chandsai yoti in india. It will grow very fast and can be useful various purposes. It can grow with normal rain fall and non forest and degraded land can be effectively useful to cultivate the plant. The plant bring in starts the third year onwards and will continue to give 25 years. It is fertilize by a seed or stem. The assets of the oil is given in the table.[1]
