The Application of Aluminum and Hydrochloric Acid to Produce Hydrogen for Internal Combustion Engine Via Hydrogen Mixture with Gasoline based on Specific Fuel Consumption

Combustion performance from the use of hydrogen generated through chemical activity between aluminum and hydrochloric acid that can be applied as an alternative fuel source for internal combustion engine needs is the aim of this paper. Applications of a mixture of hydrogen with petrol can be used to increase the combustion performance especially on the effect of sfc. Sfc is the parameter used in stoichiometric ratio for the combustion process. The methodology includes the production process of hydrogen, interpretation of reaction rates and the effect on specific fuel consumption (sfc) for internal combustion engine. 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 + H-2) with an average value of 98 g/kWh compared to the engine (G) with an average value of 123 g/kWh.
