Recently, research on internal combustion spark-ignited engines has focused increasingly on charge control by means of direct injection. The concepts proposed in this field involve in most cases high-cost systems which do not seem to be widely applicable, especially to small, low-cost engines. In this respect, the challenge is to avoid complicating the existing power systems that make of simplicity and low cost their better qualities. The paper reports on the design and realization of a two-stroke gasoline direct-injection engine prototype which employs a Water-Hammer effect injection system. The experimental data obtained with the prototype are presented showing how the system significantly reduces hydrocarbon emissions and specific fuel consumption.
