Abstract

This experimental study paper investigation mainly focused on CI engine performance with using the palm oil methyl ester (POME). The injection timing (IT) varied from 19° btdc, 23° btdc, 27° btdc and 31° btdc with increment step of 4° CA and similarly, injection opening pressure were varied from 210 bar, 220bar, 230 bar, 240 bar and 250 bar with increment order of 10 bar in the existed diesel engine. The final results were reported for optimized parameters of diesel engine with engine speed 1500 rpm and CR 17.5. The experimental results of diesel engine performance improved in terms of brake thermal efficiency (BTE) and substantial reduction of harmful emissions at both optimized engine parameters of 27°BTDC and 240 bar, when engine has powered with Palm oil methyl ester (POME) as a alternative fuel.

Highlights

The many researchers have worked on the biodiesel fuels in diesel engine and they were reported that, there were many methods and several research works has been carried out on conventional diesel engine (Murugesan et al, 2009; Atadashi et al, 2010; Banapurmath et al, 2009)
In the first phase of study, various injection timing (IT) of 19°, 23°, 27° and 31°BTDC were selected for engine operated with palm oil methyl ester (POME) and diesel fuels
The experiments were conducted in engine at various injection timings such as 19°, 23°, 27° and 31° BTDC with manufactured recommended engine parameters of IOP

Summary

Introduction

The many researchers have worked on the biodiesel fuels in diesel engine and they were reported that, there were many methods and several research works has been carried out on conventional diesel engine (Murugesan et al, 2009; Atadashi et al, 2010; Banapurmath et al, 2009). The engine is emitting very harmful pollutants to the environment. The external agencies are framed the emissions norms to reduce the emissions from diesel engine (Mani et al, 2011). Days pollution increases day by day, research activities has taken very hard decision to control the pollutants from diesel engine. Many countries currently using the edible and non edible oils such as palm, soybean, cotton seed, Jatropha curcas, pongamia pinnata and linseed biodiesel fuels. The usage of these fuels in existed diesel engine ensured higher efficiency, by the comparison, efficiency of mineral diesel fuel showed higher efficiency as compared with biodiesel
