Latest Patents
Among Kouhei Iwai's latest innovations are his cutting-edge spark-ignition direct-injection engine designs. The first patent outlines a sophisticated controller that manages fuel injection into the engine cylinder at a high pressure of 30 MPa or above. This management occurs during critical phases of the engine cycle, ensuring optimal performance in both low and high load ranges. The controller expertly adjusts the Exhaust Gas Recirculation (EGR) ratio and the timing of fuel injection between the two operating ranges, enhancing combustion efficiency.
His second recent patent describes a dual-mode spark-ignition direct injection engine, which allows for a seamless transition between compression-ignition and spark-ignition modes. This innovative feature enables the engine to operate in a compression-ignition initial mode immediately after switching from spark-ignition mode, with fuel pressure maintained at levels above 30 MPa. This design allows the air-fuel mixture to auto-ignite, improving overall engine efficiency and reducing emissions.
