Latest Patents

Iijima holds a patent for a fuel injection pump designed for internal combustion engines. This invention features a first plunger pump that injects fuel into the combustion chamber during the initial periodical compression strokes as the crankshaft rotates. Additionally, a second plunger pump injects fuel during subsequent compression strokes. The design ensures that the maximum fuel injection quantity during the second compression stroke is less than that of the first, optimizing fuel efficiency. A sensor detects the engine load, allowing a mechanism to adjust the timing of the compression strokes based on the detected load, thereby improving engine performance.
