Abstract
Fossil fuels are energy sources widely used in the transportation sector, but are also exhaustible sources and pollutants. Many studies have been developed about alternative sources capable of ensuring efficiency in energy conversion and reduction of current pollution levels. The addition of hydrogen to the engine supply seems to have great practical advantages due to the properties of that gas, although its production by electrolysis is costly. The main goal of this study is to investigate the engine performance using hydrogen as supplementary fuel in a spark ignition (SI) engine powered by gasoline. Hydrogen was produced by a hydrolytic cell and injected into the air intake. Three different flow rates of hydrogen were used as supplementary fuel. The experiments were carried out in an inertial dynamometer. The performed curves of engine torque and power were built for a range of 1000 to 6000 rpm. The fuel consumption and hydrocarbons (HC), carbon monoxide (CO) and carbon dioxide (CO2) emissions were evaluated for three different rotation speed and three different flow rates of hydrogen. The results showed some contribution of the hydrogen to the increase of torque and power and to the reduction of the specific consumption of gasoline. Furthermore, the experimental tests allowed making important analysis about the use of hydrogen in SI engines.
