He has made significant contributions to the field of automotive engineering, particularly in the development of direct injection gasoline engines. With a total of 5 patents to his name, Fukube's work has had a considerable impact on engine performance and efficiency.

Latest Patents

Fukube's latest patents include a "Device for controlling direct-injection gasoline engine" and a "Control device for direct injection gasoline engines." The first patent describes an engine that comprises an engine body, an injector, and an engine controller. The engine body features a piston within a cylinder, creating a combustion chamber. The injector is designed to inject fuel containing gasoline into the combustion chamber through a nozzle port. The engine controller enables the injector to inject fuel during the latter half of the compression stroke and manages the injection conditions. Notably, the injector has a parameter that adjusts the spread of the fuel spray, which the engine controller modifies based on the pressure in the combustion chamber.

The second patent outlines a control device that regulates the fuel injection aspect of an injector. This device can switch between two injection modes: a first mode with multiple small injections and a second mode with larger injections, depending on the engine's operating state. These innovations are crucial for enhancing the efficiency and performance of gasoline engines.
