Abstract: CI engine have always been the primary choice for on-road, agriculture and industrial applications. On-road operations are dominated by CI engines because of their better efficiency, fuel availability and fuel economy. Worldwide, nearly 14% of greenhouse gas emissions are releasing from the world’s highest energy demanding sector, transportation. The day-by-day increase in diesel engine’s use associated with the aspiration of underdeveloped or developing countries to improve their economic status has led to increase the demand for diesel fuel supply, which is causing running out of fossil fuel very shortly. The increasing fuel usage will increase the level of air pollutants in the atmosphere, which are threatening the environment and human health. Fossil fuel depletion and harmful exhaust gas emissions has created an intensive interest for the development of renewable alternative fuel. Since last three decades, researchers are showing interest to develop an alternative fuel from biomass-based feed stock. Fuels developed from biomass-based feed stock are referred as biofuels. These biofuels can be categorized into bio-alcohols and biodiesel, which are more suitable to use as an alternate fuel for SI and CI engines because of their high octane and cetane numbers respectively. This paper presents the exhaustive review of literature on testing of different renewable alternative biofuels under different testing conditions in CI engine to replace petroleum diesel and to have effective control over the harmful exhaust emissions. This paper also gives insight of recent trends in development of fourth generation biofuels based on photobiological solar fuels and electro fuels, which can be a more promising alternate fuel in the field of biofuels.
