The continuous increasing demand for energy and the decreasing petroleum resources has led to the search for alternative fuels which is renewable and sustainable. In search of alternative fuels for CI engines, many experimental studies have been carried out. This paper presents a comprehensive review on the performance and emissions of compression ignition engine using HHO and biodiesel as alternate fuel or supplement to diesel fuel. The properties of HHO and biodiesel have also been described. The experimental setup used by different researchers for the evaluation and their results regarding performance and emission with respect to diesel have been presented for several studies. The overall impression is that the performance of the engine is improved with use of HHO and biodiesel and environmental aspects are significantly improved.
