Latest Patents

Ichikawa's latest patents include two key inventions that demonstrate his expertise in fuel injection apparatuses.

The first is a **Fuel Injection Apparatus for Engine**, designed specifically for diesel engines. This apparatus features a fuel injection pump that feeds fuel under pressure and fuel injection nozzles that inject the fuel into the engine. It incorporates a pressure sensor that detects fuel pressure in the fuel line connecting the injection pump to the injection nozzles. An electronic control unit (ECU) computes the frequency of the fuel pressure based on the detected values from the sensor immediately following fuel injection. The ECU also calculates the fuel bulk modulus, which is used to determine the optimal fuel injection start and end times, adjusting the instruction values for fuel injection control accordingly.

The second patent, **Roller Bush for Fuel Injection Pump**, involves a critical component within the fuel injection pump. This roller bush is placed between a metal roller and a pin, allowing the roller to make contact with a cam that reciprocates a plunger. Notably, the axial end portions of the bush are completely made of ceramic, each possessing a specific length ratio to the total length of the bush, enhancing durability and performance under operational stresses.
