Moringa Oil

World at present is confronted with the twin crisis of fossil fuel depletion and environmental pollution. Rapid escalation in prices and hydrocarbon resources depletion has led us to look for alternative fuels, which can satisfy ever increasing demands of energy as well as protect the environment from noxious pollutants. In this direction an attempt has been made to study a biodiesel, namely Moringa Oil Methyl Esters [MOME]. All the experiments were carried out on a 4.4 kW naturally aspirated stationary direct injection diesel engine coupled with a dynamometer to determine the engine performance and emission analysis for MOME. It was observed that there was a reduction in HC, CO and PM emissions along with a substantial increase in NOx. MOME and its blends had slightly lower thermal efficiency than diesel oil.

This paper present a study of the effects of duration of injection on emissions and combustion characteristics in a direct injection diesel engine using CFD code KIVA-3V. In this study, duration of injection was also changed from 6o to 12o CA while the injection timing is constant to evaluate the effect on DI Diesel engine performance, indicated specific fuel consumption and particulates and oxides of nitrogen emission. The obtained results indicate that the capacity of the engine reaches its maximum value and NOx and soot emissions is decreased when the duration of injection is in the range of 6o to 9o CA.

The present study investigated the performance and emission characteristics of a single cylinder direct injection diesel engine fuelled with diesel – jatropha biodiesel – pentanol blends. The test fuels used for the experiment include diesel fuel (Diesel), 80% diesel (v/v) – 20% jatropha biodiesel (v/v) (D80J20), 70% diesel (v/v) – 20% jatropha biodiesel (v/v) – 10% pentanol (v/v) (D70J20P10), and 60% diesel (v/v) – 20% jatropha biodiesel (v/v) – 20% pentanol (v/v) (D60J20P20). Studied performance characteristics include brake specific fuel consumption and torque, while emission characteristics include carbon monoxide, nitrogen oxides, and smoke opacity. Experimental results revealed that the addition of pentanol influenced a reduction in brake power and torque with a noticeable improvement in engine exhaust emissions. To conclude, the addition of pentanol (20%, v/v) to diesel–jatropha blends resulted in lowered CO, NOx, and smoke opacity by 41.76%, 27.6%, and 32.4%, respectively, because of improved oxygen content of the resulting ternary mixture and improved combustion efficiency.

Performance Behavior

Jatropha bio diesel blended with mineral diesel in proportion 2:1 by volume is used to conduct performance test and emission characteristics of a single cylinder direct injection diesel engine. Jatropha-diesel blend is used to perform engine performance and emission tests at variable loads & throttle settings (25%, 50%, 75% and 100%). Observed data were utilized to obtain various performance parameters such as brake power, brake specific fuel consumption, brake thermal efficiency at various loads and throttle settings. Simultaneously observations were also made to obtain exhaust gas temperatures and exhaust emissions (CO, CO2, HC and NOx). In existing engine diesel provides higher and economic power generating capacity for entire operating ranges but effect of varying load /throttle on performance behavior were fantastically similar. Reduced HC and NOx emission with the blend also better, highlights some positive aspects of combustion and allowance for higher compression ratio with the blend.
