The intent of this paper is to summarize the state of knowledge on use of vegetable oils as diesel fuels. Fuel related properties are reviewed and compared with conventional diesel fuel. The use of neat vegetable oil (edible and/or nonedible), biodiesel and its blends in a diesel engine has been discussed. Performance and emission characteristics are highlighted. Suitability of different combustion chambers for diesel engine operation with vegetable oils is outlined. Techniques to decrease viscosities are discussed. An overview on current developments on the use of vegetable oils directly and indirectly in diesel engines is presented.

The stability and emission characteristics of diesel-ethanol-coconut methyl ester (CME) blends were studied to determine the most suitable fuel blends to be applied in diesel engines. This is done in order to assess the potential of the blends as a substitute for commercially available diesel fuel used in diesel engine. The stability results of the blends using 100% and 99.5% ethanol purity showed that the fuel blends containing ethanol up to 10% and CME of 5% and greater exhibited high mutual solubility at any temperature range and were resistant to microbial growths after 3 months storage. Engine operations at low speed especially at idle-no load and using a bigger size engine lead to a minimum ignition delay and result in lower fuel consumption rate. The emission test results with the new- blended fuels showed a reduction in CO2 and increasing percentage by volume of CO2 compared to commercially available diesel. The blends could deliver an efficient combustion and could run efficiently since production of the CO2 gases is higher than that of CO. The blends of 80% diesel, 5% ethanol, 10% CME; and 80% diesel, 10% ethanol, 10% CME could reduce the smoke opacity compared to commercially available diesel.

Palm Biodiesel, which can be produced from transesterification palm oil with methanol, is an alternative fuel for diesel engines. It can be mixed with diesel fuels and used in diesel engines with no or slight modification. Therefore, in this study, commercially available diesel fuel was blended with biodiesel produced from transesterification of palm oil. The stability of the pure palm biodiesel (B100) was investigated over a storage time of 2, 4 and 6 months. The study assessed the corrosion rate of metals exposed to palm biodiesel. The kinematic viscosity, density and flash points of the blends increased with biodiesel amount in the fuel blend. However, pour point of the blends decreased as the amount of biodiesel in the blends is increased. Kinematic viscosity, pour point and flash point slightly increased with storage time. The average corrosion rate for copper is 0.5341 mpy, 0.2438 mpy for aluminium and 0.1802 mpy for mild steel.

In this paper the emission characteristics and performance of various bio diesel fuels (Tyre pyrolysis oil (TPO), Micro algae oil and Pig animal fat oil) were experimented. A single cylinder, water cooled diesel engine was modified in to homogeneous charge compression ignition engine (HCCI) with adopted port fuel injection (PFI) technique. The effects of air fuel ratio, intake temperature, injection pressure and EGR rate exhaust emissions were explained in a broad manner. The analysis of the exhaust emissions are integrated to oxides of Nitrogen (NOx), Carbon Monoxide (CO), unburned hydro carbons (UHC), smoke and soot. The performance analysis was also included on specific fuel consumption and break thermal efficiency. The basic requirements for HCCI engine is the homogeneous mixture preparation of air and fuel. This mixture formation was done by adopting port fuel injection technique and external devices were also used for bio diesel vaporization and mixture preparation. The combustion processes were measured with different EGR system.  The experimental results of different bio diesel fuels with HCCI engine mode were recorded and evaluated. A small increase in CO and HC emissions were observed with increasing bio diesel content due to slow evaporation rate of bio diesel. A significant reduction in NOx emission was also observed with respect to difference in bio diesel blends. Micro algae oil was found more stable compared with other bio diesel fuels due to the property of fuel vaporization and low heat releasing.
