Latest Patents

Ichimura's latest patents focus on innovative variable valve timing controllers for internal combustion engines. The first patent describes a system that switches between reference timing control mode and feedback control mode based on engine speed and target valve timing. Specifically, when the engine speed exceeds a predetermined threshold and the target advanced amount of intake valve timing is lower than a specific switching threshold, the intake variable cam timing (VCT) is switched to reference timing control mode. Similarly, if the target retarded amount of exhaust valve timing is below the threshold, the exhaust VCT also switches to reference timing control mode.

The second patent outlines a method for managing the operation of both intake and exhaust-side variable valve timing devices. When the target advance angle of the intake valve and the target retard angle of the exhaust valve are both at or below a certain threshold, both devices revert to a base mode. Conversely, if the target advance angle of the intake valve exceeds the threshold while the target retard angle of the exhaust valve also exceeds its threshold, both devices are activated into feedback mode simultaneously.
