Abstract
Problem statement: The increasing awareness of the environmental hazards and the alarming levels of air pollution have led to more restrictive regulations on engines emission control in recent years. Approach: The dwindling resources and rising cost of crude oil had resulted in an intensified search for alternate fuels. In the present study biodiesel (palm oil methyl ester) blends with diesel was investigated in a direct injection stationary diesel engine. The stationary engine test bed used consists of a single-cylinder four stroke diesel engine, eddy current dynamometer with computer control data acquisition system and exhaust emissions analyzer. Results: Engine tests were conducted at constant speed using neat diesel fuel and various proportions of biodiesel blends. The exhaust emissions such as CO, HC and NOx were measured using exhaust gas analyzer. Performance characteristics like brake thermal efficiency and specific fuel consumption were recorded. The differences in the measured emissions and performance of the biodiesel-diesel fuel blends from the baseline operation of the engine, i.e., when working with neat diesel fuel were determined and compared. Conclusion: It is concluded that the lower blends of biodiesel increased the brake thermal efficiency and reduced the fuel consumption. Biodiesel blends produces lower engine emissions than diesel. From the result, it has been established that 20-40% of palm oil biodiesel can be use as a substitute for diesel without any engine modifications.
Highlights
In the 1930s and 1940s vegetable oils were used as Diesel engines are the major source of diesel fuel from time to time, but only in emergency transportation, power generation, marine applications, situations
The present study aims to investigate the use of palm oil as an alternate fuel for compression ignition engine
Biodiesel Preparation: Biodiesel is the ester of Table 2: Specification of test engine vegetable oils produced through a process called Engine type
Summary
In the 1930s and 1940s vegetable oils were used as Diesel engines are the major source of diesel fuel from time to time, but only in emergency transportation, power generation, marine applications, situations. Vegetable its help on reducing a country’s reliance on crude oil oils have become more attractive recently because of its imports, its supportive characteristic on agriculture by environmental benefits and the fact that it is made from providing a new market for domestic crops, its effective renewable resources. Vegetable oils are a renewable lubricating property that eliminates the need of any and potentially inexhaustible source of energy with an lubricate additive and its wide acceptance by vehicle energetic content close to diesel. More than one manufacturers can be listed as the most important hundred years ago, Rudolf Diesel tested vegetable oil as advantages of the biodiesel fuel (Srivastava and Verma, the fuel for his engine (Sharma et al, 2008; Anbumani 2008; Karaosmanoplu, 1999; Lawrence et al, 2011; and Singh, 2010). The present study aims to investigate the use of palm oil as an alternate fuel for compression ignition engine
