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 paper, an attempt is made to assemble and summarize a listing of important research articles on low-temperature combustion using a wide variety of conventional and alternate renewable fuels, and the effect of low temperature combustion on engine performance and emission characteristics over a wide range of engine test conditions.

TL;DR: In this paper, the effect of start of injection, fuel formulation, and blends of biodiesel fuels on the emission characteristics of diesel fuel has been investigated and validated with the experimental results at a wide range of speed and load conditions.

TL;DR: In this paper, a phenomenological model is developed to enable parametric understanding of the combustion and emission characteristics of multiple-injection common rail direct injection engines, based on a two-zone formulation comprising of fuel-air spray and the surrounding air.

TL;DR: In this article, the effect of operating parameters such as fuel quantity and the dwell period between the injection pulses for biodiesel blend (B20) fuel was investigated in an automotive LDD CRDI Engine.
