Abstract: A lot of research is being conducted to use high-efficiency equipment and low-carbon / carbon-free fuel to solve the problem of global warming. In the engine sector, interest in high-efficiency diesel engines has been high, but direct combustion of fossil fuels has limitations in reducing greenhouse gas emissions. Research is ongoing. Recently, there is a high interest in e-Fuel as an alternative fuel, such as hydrogen, ammonia, methane, methanol, and ethanol DME. LPG is known as a fuel that can be produced as an e-Fuel. When such an e-Fuel is used in a diesel engine, it is possible to achieve high efficiency due to the high compression ratio of a diesel engine and to achieve a much lower level of harmful exhaust gas concentration than a diesel engine. However, problems due to fuel-slip may occur. In this study, a system capable of supplying CNG (Compressed Natural Gas), LPG (Liquified Petroleum Gas), NH3, etc. was applied for co-combustion, and each performance was confirmed. The engine used in the experiment is a 3.9-liter four-cylinder CRDI engine and is equipped with a turbocharger. When each fuel was used for mixed firing, maximum output was secured. However, in the exhaust gas, HC and NH3-slip increased. In the case of NOx, there was also a decrease, which is judged to be due to interference with combustion by the fuel used for co-firing
