An experimental study of Pongamia pinnata L. oil as a diesel substitute

Abstract

Present work deals with testing a performance of a compression ignition (CI) engine with different blends of non-edible oil as well as their methylesters with petrodiesel. Various blends of a non-edible vegetable oil, commonly known as honge (Pongamia pinnata L.) in India, were prepared and tested over a wide range of engine load. Results obtained from the study showed that 15 -20 per cent pongamia methylester-diesel blend (B15 and B20) could be a better fuel in terms of fuel efficiency and power developed. Further, the blend can be used in any existing CI engine without modification and preheating. The pongamia oil is transesterified by using base catalysed transesterification process in a batch type transesterification reactor. Transesterification shows improvement in fuel properties of pongamia oil. Results obtained with B15 and B20 show improvement in brake thermal efficiency and reduction in brake specific fuel consumption, especially at higher load. Emission results show significant reduction in percentage of CO and HC for B15 and B20 at medium and higher power output.

Effects of Al2O3 coating on diesel engine performance, combustion, and emission characteristics fueled by pongamia methyl ester and its blends with diesel

“…The literature showed that only few studies are available on effects of biodiesel in the LHR engine, an experimental study is needed with various biodiesel to identify best fuel for LHR engine. In this study, an experiment was carried out to characterize the performance, combustion and emission of pongamia methyl ester blends with diesel [18][19][20][21][22] and comparison was made with Al 2 O 3-coated and uncoated engines.…”

Engines for Combined Heat and Power

“…cetane number) of the fuel. Compression ratio, engine speed, cylinder gas pressure, temperature of the air intake and quality of fuel spray affect the ignition delay period [39]. In the case of DSPO-BD blends the start of combustion was delayed compared to FD at most load conditions.…”

Investigation of Effect of Injection Pressure on Performance and Emission Characteristics of Composite Oil Biodiesel on DI CI Engine

“…Suryawanshi et al [18] experimented using blends of Pongamia methyl ester with diesel fuel and found a reduction in HC and CO (Carbon Monoxide) emissions at part loads as well as full load compared to diesel fuel. Grimaldi et al [19] concluded that BTE was found higher in blends of biodiesel compared to diesel fuel at high loads in a diesel engine.…”
