AB - High torque and thermal efficiency, durability, reliability, fuel economy, and low emission of carbon dioxide are the factors that made of diesel engine as a preferable engine in passenger transport, trucks and power generation. In contrast, high localized temperatures along with heterogeneous combustion of the fuel-air mixture have made the diesel engine yields a high level of particulate matter and nitrogen oxide emissions. In addition to the problems of diesel engines, the fear of depleting energy sources along with environmental pollution and global warming as a result of using fossil fuels prompted researchers to find many types of alternative fuels. HCNG is a mixture of hydrogen (H-2) and compressed natural gas (CNG) that is used as an alternative fuel for diesel engines at varying substitution ratios. The objectives of using HCNG are to maintain or improve engine efficiency and reduce exhaust emissions in addition to the cheapness of this fuel compared to diesel. Many researchers have conducted theoretical and experimental research on the use of HCNG fuel with diesel engines, but there are few literature review studies in this area. Therefore, in this research, the results of a number of pre-prepared studies regarding the performance and exhaust emissions of a HCNG tri-fuel diesel engine were reviewed and summarized. Engine performance is represented by in-cylinder pressure, heat release, brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), brake power (BP), and brake torque (BT).
