Latest Patents

Ichimiya's latest innovations include two notable patents:

1. **Device for Locking/Unlocking Rotation of an Eccentric Bearing**: This device is designed to lock or unlock the rotation of an eccentric bearing situated between the piston-pin and connecting rod of an internal combustion engine. This innovation facilitates changing the compression ratio of the engine. The eccentric bearing features two lock holes and guide grooves, which ensure reliable engagement with a lock-pin inserted in the connecting rod. This development allows for effective transitions between high and low compression ratios, enhancing engine versatility.

2. **Auxiliary Apparatus for Hot-Starting Internal Combustion Engine**: This apparatus addresses the challenge of hot-starting an internal combustion engine. It incorporates a secondary air injection nozzle within the intake manifold and a heat-sensitive solenoid valve that manages secondary air flow. When engine temperatures rise beyond a set threshold, the valve activates, supplying a jet of air to create a leaner mixture in the manifold. This process not only reduces harmful exhaust emissions but also improves the startability of hot engines.
