ABSTRACT Conversion of a Gasoline Engine to a Hydrogen Engine An inexpensive hydrogen injection system was designed, constructed and tested in theMechanical Engineering laboratory. It was used to supply hydrogen to a gasoline engine to runthe engine in varying proportions of hydrogen and gasoline. A factory-built injection and controlsystem, based on the injection technology from the racing industry, was used to inject gaseoushydrogen into a gasoline engine to boost the efficiency and reduce the amount of pollutants inthe exhaust. A fully programmable NOS Launcher Progressive Nitrous Controller was used withthe ability to control injection of a fuel based on engine performance parameters such as RPMand manifold air pressure. The system was first tried successfully on a 2-cylinder Briggs &Stratton gasoline engine. It was then modified to fit on a 6-cylinder TOYOTA gasoline enginemounted on a computer-linked test stand. The test stand is equipped with sensors andmeasurement systems that can be programmed to measure and record the parameters in theperformance analysis of an IC engine, including: power, rpm, torque, air-fuel ratio, temperatures,thermal efficiency, pressures etc. The computerized test stand can be used to compare theperformance of the engine with gasoline and hydrogen in any pre-selected proportions of the twofuels (0% to 100%). Both these engines are still operational and are being used for studentexperiments in the Mechanical Engineering department. The project demonstrates an economical(approximate cost: $1000) hydrogen injection system that could be built from readily-available,off-the-shelf components for a gasoline engine equipped with an on-board computer (ECU)designed to control combustion.
