ABSTRACT
Due to rapid industrialisation and use of advanced technologies there has been increase in the
consumption of fossil fuels, especially petroleum. Increasing needs are reciprocally
proportionate to diminishing reserves of coal and petroleum. So, the exaggerated to be
fulfilled and to curb the problem of increasing fuel prices; researchers are putting their efforts
to produce an alternative fuel from replenish able resources on large scale. To cater the huge
demand of energy, need of hour is to look for alternative sources. Biodiesel is one of the
promising alternative to petroleum diesel as it is renewable in nature. Biodiesel itself is
proving to be a reliable and competent competitor to non-renewable petroleum which is being
produced from commonly accustomed plants for instance rapeseed, soybean, sunflower and
palm etc. But, complication is that it becomes a problem for in-availability of these oils for
foods. Now non-edible raw materials oils such as Pongamia, Jatropha, Waste cooking oil,
Mahua, Moringa seed oil etc. have been used to raise the standard of these oils and being
produced to complete the level of petroleum and be proven as the best resources for biodiesel
production in all approaches both technically and economically.
As the single biodiesel lacks in some properties for using in diesel engine, therefore to
get the desirable properties, there are various methods, such as addition of additives, blending
with higher alcohol and blending with other biodiesels. This thesis focuses primarily on
different properties of binary blends of biodiesels, which can be used as fuel in diesel engine.
In this thesis, only biodiesels (without blended with diesel) are used to check the performance
of the diesel engine. The different ratios of different biodiesel blends of WCB (Waste
Cooking Biodiesel) and JCB (Jatropha Curcas Biodiesel) have been mixed to get the
desirable fuel properties to suit engine. The study showed that WCB:JCB (80:20) blend is the
best blend in terms of fuel properties and engine application. The BSFC of this blend is found
14% higher while BTE is lower than diesel at full load conditions. The CO and HC emission
is 17% and 42% lower while NOx emission is 20% higher compared to diesel. The results
showed that the binary blends can be recommended as an alternative fuel to diesel and it can
be used in engine with or without NOx reducing additives.
