Investigation of Cold Start Capability of a Briggs and Stratton Engine Using Jet A Fuel and Microwave Plasma Ignition
There is a growing interest in improving engine versatility through the capacity to run on more than one fuel. To aid in this effort, the research presented in this paper investigated a novel system using microwave plasma ignition designed with the goal of allowing standard gasoline engines to run on non-standard fuels. The fuel used was Jet A. The test engine was a Briggs and Stratton single cylinder engine outfitted with an aftermarket fuel injection system and the microwave plasma ignition system. The tests performed were to determine the cold-start temperature limit, the lowest temperature at which the engine could be repeatedly started, using microwave plasma ignition with a conventional spark plug as a reference. A detailed system outline is presented, as well as results and conclusions. Recommendations for further research are also suggested.
