Hydrogen mixture with gasoline for conventional motorcycles and effect on mass flow rate, brake thermal efficiency and emissions

Abstract

The fossil fuel price crisis and emissions control in the transportation sector in Malaysia have become national issues, especially in the transportation sector. As an alternative, using hydrogen mixed with gasoline fuel in conventional combustion engines is a very effective way of improving engine performance and emission control. Generating hydrogen via a chemical reaction between hydrochloric acid and aluminium is a new approach in this study. This methodology has been tested through the mixture application (G + H2) in 10-year-old motorcycles (gasoline) with a modified conventional carburettor engine. The testing of engine performance by chassis dynamometer was done at three levels of experiments: L0: 0 Amp load, L1: 1 Amp load, and L2: 2 Amp load for different engine performances, particularly in identifying quality improvements through the brake thermal efficiency. The study found that the average increase in brake thermal efficiency was 23% higher in the (G + H2) engine compared to gasoline only. The results of this study have proven that the use of hydrogen (Al + HCl) in the stoichiometric ratio has helped to increase combustion efficiency, especially when the oxygen content in the fuel mixture ratio is not adequate during the stroke of power. The successful reduction in fuel consumption, increased engine performance, reduction of pollution and the system’s ability to meet the basic needs of the internal combustion engine cycle can be beneficial to the development of the automotive industry, particularly in the transport sector.
