Performance analysis of palm, jatropha and moringa biodiesels in a diesel engine / Md. Mofijur Rahman
The global energy consumption is expected to grow in a faster rate than the population growth. By 2030, an increase of 53% of global energy consumption and 39% of greenhouse gases emissions from fossil fuels are anticipated. Therefore, it has become a global agenda to develop clean alternative fu...

description |
The global energy consumption is expected to grow in a faster rate than the population
growth. By 2030, an increase of 53% of global energy consumption and 39% of greenhouse
gases emissions from fossil fuels are anticipated. Therefore, it has become a global agenda
to develop clean alternative fuels which are domestically available, environmentally
acceptable and technically feasible. As an alternative fuel, biodiesel seems as one of the
best choices among other sources due to its environment friendly aspect and similar
functional properties as diesel fuel. This research aims to produce biodiesel from some
edible and non-edible oils that are either readily available or have native distribution in
Malaysia. These oils include; Palm (Elaeis guineensis), Jatropha curcas and Moringa
oleifera oils. This was followed by a detailed investigation of physic-chemical properties of
the produced methyl esters such as kinematic viscosity, density, flash point, cloud point,
pour point, cold filter plugging point, viscosity index and oxidation stability. This research
also discusses the concept of biodiesel-diesel blending to improve some of the properties.
Moreover, 5%, 10%, 15% and 20% by volume blends of Palm, Jatropha curcas and
Moringa oleifera were used to evaluate their performance in a Mitsubishi Pajero
turbocharged diesel engine. According to the results of the investigation, the produced
methyl esters meet biodiesel standard specification. Moreover, blending of biodiesel with
diesel fuel improves their fuel properties. The results of engine performance indicated that
over the entire range of speed, biodiesel blended fuels give average reduction in torque,
brake power and increased brake specific fuel consumption values compared to diesel fuel.
In case of engine emission, biodiesel blended fuels give an average reduction in carbon
monoxide and hydrocarbon emissions whereas slightly increased nitric oxides and carbon
dioxides emissions respectively compared to diesel fuel. Overall, Palm biodiesel blended
fuel showed better performance than Jatropha curcas and Moringa oleifera biodiesel
blended fuels. In conclusion, Palm, Jatropha curcas and Moringa oleifera are potential
feedstock for biodiesel production, and up to 20% of their blends should be considered to
replace diesel fuel without engine modification to reduce the dependency on petro-diesel
and produce cleaner exhaust emissions. |
