Latest Patents

One of Komuro's latest patents focuses on a direct-injection engine, along with methods of controlling it, a piston used in the engine, and a fuel injection valve. This innovative injector features three concentrated fuel spray bands. One of these spray bands is directed towards a spark plug, while the others are aimed at curved grooves on the piston. The sprays entering each groove advance along the grooves, colliding under the spark plug and ascending. This design allows the spray bands to be carried to the vicinity of the spark plug by a tumble flow, resulting in a stable stratified air-fuel mixture. As a result, stable and satisfactory stratified combustion can be achieved.
