“…The advanced start of ignition is occurred due to the physical properties of the biodiesel such as higher bulk modulus [14], [46] higher viscosity [41], [45] and higher cetane number [47], [16]. It is well documented from previous reports that biodiesel cetane number is higher than diesel which mainly causes for start of early ignition for engine running with biodiesel [33], [58][59][60]. Further it can be seen that at lower load conditions the test CI engine running on diesel has a higher peak heat release rate than the biodiesel by 4%.…”

Biodiesel is one of the alternative fuels which is renewable and environmentally friendly and can be used in diesel engines with little or no modifications. In the present study, experimental investigations were carried out on the effects of biodiesel types, biodiesel fraction and physical properties on the combustion and performance characteristics of a compression ignition (CI) engine. The experimental work was conducted on a four-cylinder, four -stroke, direct injection (DI) and turbocharged diesel engine by using biodiesel of waste oil, rapeseed oil and corn oil and normal diesel. Based on the measured parameters, detailed analyses were carried out on cylinder pressure, heat release rate and brake specific fuel consumption (BSFC). It has been seen that the biodiesel types do not result in any significant differences in peak cylinder pressure and BSFC. The results also clearly indicate that the engine running with biodiesel have slightly higher in-cylinder pressure and heat release rate than the engine running with normal diesel. The BSFC for the engine running with neat biodiesel was higher than the engine running with normal diesel by up to 15%. It is also noticed that the physical properties of the biodiesel affects significantly the performance of the engine.

“…As for diesel, this low cetane number for vegetable oils leads to incomplete combustion when the engine is idling, difficult cold starting of the engine and increased engine noise. It is known that the self-ignition delay of fuels decreases as their injection temperature increases [28,60,61].…”

“…Increased viscosity due to poor atomisation has previously been suggested as a reason for extended ignition delay (Rodríguez et al, 2011). The longer ignition delay of B100 can therefore be attributed to its higher viscosity.…”

The variability in viscosity and combustion quality has been identified from the literature as a barrier to the use of biodiesel fuels in motorsport. These parameters can affect performance, emissions and fuel consumption. Diesel engines have had recent success in endurance and touring car racing;biodiesel is an opportunity to increase the sustainability of this emerging area of motorsport.Methyl esters from rapeseed, soybean and sunflower oils were tested alongside EN 590 diesel fuel.Variations in fuel consumption, output torque and power were observed between the fuels. Further tests were carried out on an automotive diesel engine to evaluate the in-cylinder pressures for soybean B100, beef tallow B50 and EN 590 to gain understanding of the reasons behind the performance differences noted in the initial tests.Retarding the start of injection for B50 and B100 biodiesel improved the peak torque by up to 5% enabling the production of equal torque at the same engine speed when compared to EN 590 but with lower peak in-cylinder pressure and a shorter ignition delay. The application of this to motorsport is the potential to achieve higher peak power outputs; the shorter ignition delay and more rapid combustion has the potential to be used to raise the maximum engine speed and therefore the peak power output of diesel engines for motorsport.
