The Effect of Methyl Ester Jatropha Oil with Dimethyl Ester Derivatives on Diesel Engine Performance and Emissions: A Review

Introduction

The increasing demand for energy and the need to reduce greenhouse gas emissions have led to the exploration of alternative fuels for diesel engines. One such alternative is methyl ester jatropha oil, which has been shown to have potential as a renewable and sustainable fuel source. However, the performance and emissions of diesel engines using methyl ester jatropha oil with dimethyl ester derivatives are not well understood. This review aims to examine the effect of methyl esters of jatropha oil with oleat derivatives on diesel engine performance and emissions.

Background

Jatropha oil is a non-edible oil that is extracted from the seeds of the Jatropha curcas plant. It is a promising alternative fuel source due to its high energy density and low sulfur content. The transesterification process is used to convert jatropha oil into methyl esters, which can be used as a diesel fuel substitute. However, the addition of dimethyl ester derivatives to methyl esters of jatropha oil has been shown to have a positive impact on exhaust emissions.

Methodology

This study examined the effect of methyl esters of jatropha oil with oleat derivatives on diesel engine performance and emissions. The fuel mixtures tested included B5 (5% methyl ester castor oil), B10 (10% methyl esters of castor oil), and B10mix (10% methyl ester oil and 1% dimethyl ester derivatives). Each mixture was compared to B0 (100% PERTADEX solar).

Results

The results of the study showed that the heat value of the methyl ester of Jatropha oil with dimethyl ester oleat derivatives was lower than that of PERTADEX solar oil. The diesel engine performance test, which included torque, power, specific fuel consumption, and thermal efficiency, showed some interesting results. The torque test results showed that the torque value of B0 was higher than B5, B10, and B10Mix, indicating that the use of methyl esters of jatropha oil lowered engine torque. The power test results showed that B0 power was greater than B5, B10, and B10Mix, indicating a decrease in engine power when using a mixture of methyl esters.

Discussion

The results of the study showed that the use of methyl esters of jatropha oil with oleat derivatives had a positive impact on exhaust emissions. The exhaust emission tests, which included carbon monoxide (CO), carbon dioxide (CO2), hydrocarbons (HC), oxygen (O2), and nitrogen oxide (NOX), showed significant results. The exhaust emissions from B5, B10, and B10Mix were lower than B0, indicating that the methyl ester of Jatropha and Dimethyl Ester Oleat derivatives were able to suppress exhaust emissions, especially hydrocarbon emissions (HC).

Conclusion

Overall, this study shows that the use of methyl esters of jatropha oil with oleat derivatives has the potential to reduce diesel engine exhaust emissions, but further research needs to be done to improve engine performance in order to compete with PERTADEX solar oil. Some aspects that can be further investigated include adjusting the ratio of methyl ester mixture, optimizing the process of oleic acid carbonylation to produce more effective oleic derivatives, and diesel engine modification to be able to use methyl ester mixtures more optimally.

Future Directions

This study provides a clearer picture of the potential for utilizing renewable resources, especially jatropha oil, as an alternative fuel for diesel engines. With a variety of further studies, it is expected that the use of methyl esters of jatropha oil with dimethyl ester oleat derivatives can produce diesel engines that are more environmentally friendly and efficient.
