Hydrogen Blended with Gasoline for Internal Combustion Engine Effect on Specific Fuel Consumption Based on Load Tests (L0,L1,L2)

Abstract:

The instability of petroleum prices in the world market has caused the price of fuel in Malaysia to increase, especially in the transportation sector. As an alternative, a research has been conducted from a technical aspect on the profitability of using hydrogen onboard as fuel for internal combustion engine. The process of producing hydrogen through chemical reaction between aluminum and hydrochloric acid (Al+HCl) has been successfully applied. Applications using a mixture of petrol with hydrogen (P+H₂) as an alternative fuel in four-stroke motorcycles have been tested using a chassis dynamometer model ATV Inertial Dyno, 054-500-1K. Hydrogen requirement in the petrol mixing ratio is dependent on the operating system of the engine ignition system which is controlled by hydrogen pressure in the cylinder. Three stages of load test on the engine performance have been conducted on the chassis dynamometer, namely, load test L0 is equal 0 ampere (L0), load test L1 is equal 1 ampere, and load test L2 is equal 2. This results showed 0.7412 mole of hydrogen can be generated through the chemical reaction between 20 grams of aluminium with 250 ml of hydrochloric acid or 1 kg of aluminium can produce 37.06 moles which is equivalent to 108 grams hydrogen. Fuel economy of each load test was 6.5% (L0), 18.5% (L1) and 30% (L2) in grams per kilowatt hour. The rate used in each test load was 100 g/kWh (L0), 80.77 g/kWh (L1), and 112 g/kWh (L2) compared to petrol of 107 g/kWh (L0), 99.23 g/kWh (L1) and 162 g/kWh (L2). Results from the combustion of petrol, air and hydrogen in proportion of 100 g/kWh, 80.77 g/kWh and 112 g/kWh was able to improve the quality of combustion compared to the normal fuel consumption. The total use of sfc achieved 20.3% savings in grams per kilowatt hour for the engine (G + H₂) with an average value of 98 g/kWh compared to the engine (G) with an average value of 123 g/kWh. The successful development of a prototype model with a reduction in fuel consumption in 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.
