Abstract: Direct injection diesel engines are more popular in the automotive sector than spark ignition (SI) engines due to its fuel lean operation However, the demand of fossil fuel is rising day by day and hence the major fuel source of diesel engine, the petroleum based fuel, is depleting rapidly Many countries depend mainly on imported fossil fuels due to lack of fuel reserves and it has great impact on the economy In addition to this, the major concerns of diesel engine are its oxides of nitrogen and smoke emissions Therefore, for the past several decades extensive efforts are being made to search for alternate fuels to overcome the dependence on fossil fuel and environment pollution In this regard, several alternate fuels namely hydrogen, oxygenated fuels like alcohol fuels, dimethyl ether and biodiesel fuels etc, have been extensively analysed Recent studies show that biodiesel is one of the most promising alternate fuels for diesel engines because of its biodegradable, oxygenated, sulphur free and renewable characteristics Hence, it is getting the attention of researchers all over the world The blends of biodiesel with fossil diesel have many benefits like reduction in emissions, lower engine wear, lesser engine oil consumption and comparable thermal efficiency vis-a-vis diesel fuel Exhaustive experimental works have been carried out to analyse the suitability of biodiesel fuel as alternate fuel and to explore their advantages in diesel engines Hence, this paper is attempted to present a comprehensive review on the performance, combustion and emission characteristics of some important biodiesel fuels on diesel engines This comprehensive review on the published literature will be helpful to the researchers to understand the state-of-the-art technology of the biodiesel fuelled compression ignition engine

TL;DR: In this article, the spray characteristics of diesel with HCB fuel blends were investigated in a constant volume combustion chamber to provide an accessible tool to predict spray behavior based on cheap and off-engine condition measurements for applying HCB in diesel engines.

TL;DR: In this article, the performance, combustion and emission characteristics of a single-cylinder, constant speed, DI diesel engine using pine oil and its blends as an alternative fuel were studied.

TL;DR: In this article, a second-generation hydrogenated catalytic biodiesel (HCB) from waste cooking oil with high reactivity is blended into the China 95#gasoline with different volume ratios, and the effect of blended ratio on the combustion and emission characteristics of a heavy-duty diesel engine was explored.

TL;DR: In this article, the effect of HCB/Diesel blended fuels properties (by mass fraction of biodiesel in diesel) on spray combustion characteristics was investigated at inert and reacting conditions in a constant volume combustion chamber.
