A comparison of diesel engine car performance using H ₂ O-CH technology

Abstract One of the ways to reduce the use of fossil fuels in transport is to use alkane gases in diesel engines. However, as the direct application of gaseous fuels in diesel engines presents technical challenges. A dual-fuel system integrating H 2 O-CH technology offers an effective solution to facilitate the use of alkane gases in internal combustion diesel engines. By partially substituting diesel fuel in the combustion chamber with a mixture of alkane gas and water vapour, a more uniform and complete combustion process can be achieved, thereby reducing diesel consumption and greenhouse gas emissions. The aim of this study is to compare the performance (power, torque, fuel, gas and water consumption) of a passenger car with a diesel engine when running on pure diesel fuel and when running on a combination of diesel and gaseous fuel using H 2 O-CH technology equipment. The performance indicators were compared in different driving modes using the chassis dynamometer Mustang MD1750, while simultaneously measuring fossil diesel, LPG (Liquefied Petroleum Gas), and water consumption. The results demonstrate that a properly integrated and calibrated dual-fuel system equipped with H 2 O-CH technology can, under certain operating conditions, achieve higher engine performance while partially replacing diesel fuel with a mixture of alkane gas and water vapour. The presence of water vapour in the fuel mixture reduces the risk of detonation in the combustion chamber and contributes to smoother and more stable engine operation.
