Latest Patents
Among his latest patents, Kidooka has developed a variable compression ratio mechanism. This innovative gear drive mechanism features a gear drive pin located at the second gear, along with a first and second movable member that can move towards the gear drive pin. The design includes a first guide groove on the first movable member that engages with the gear drive pin to facilitate rotation towards a low compression ratio position. Additionally, a second guide groove on the second movable member allows for engagement with the gear drive pin when rotating towards a high compression ratio position. This mechanism enables the gear drive pin to move relative to a counterweight, resulting in the rotation of the second gear.
Another significant patent is the variable length connecting rod and variable compression ratio internal combustion engine. This invention consists of a connecting rod body, an eccentric member, a switching mechanism, and a stopping mechanism. The eccentric member, located at the small diameter end of the connecting rod body, rotates to vary the effective length of the connecting rod. The switching mechanism includes a hydraulic piston connected to the eccentric member, allowing it to reach different positions based on the state of the mechanism. The stopping mechanism ensures that the eccentric member can be maintained at an intermediate position between the two states.
