Latest Patents

One of Okada's latest patents is a decompression device in a two-cycle engine. This invention aims to prevent the decompression passageway in a two-cycle engine from being blocked by carbon soot. By facilitating the manufacture of a two-cycle engine with a decompression structure, it eliminates the reduction of output power caused by this structure. The design includes a scavenging passageway formed along the inner wall of the cylinder, which communicates with the crankcase of the engine. Additionally, a decompression groove extends in the axial direction of the cylinder, varying in width and depth to optimize performance.

Another significant patent is for a direct-injection spark-ignition engine. This engine features a governor that senses the rotational speed and fuel injection pumps that adjust the fuel rate based on the governor's power shaft. The design includes fuel injection nozzles that directly inject fuel into the engine cylinders, along with ignition plugs for combustion. The engine is characterized by throttle valves within the suction air passages, which are controlled to increase the valve opening in proportion to the fuel injection quantity.
