Latest Patents

One of Kamichika's latest patents is the Six-Stroke Engine. This innovative engine design includes a cylinder, a piston, a cylinder head, a combustion chamber, a cylinder injector, a spark plug, an intake port, an exhaust port, an intake valve, an exhaust valve, a valve gear, and a control device. The valve gear operates the intake and exhaust valves to execute six strokes in a specific order: an intake stroke, a compression stroke without ignition, an expansion stroke without combustion, a compression stroke with ignition, an expansion stroke with combustion, and an exhaust stroke. The control device is programmed to manage fuel injection and spark plug activation during the compression stroke with ignition.

Another significant patent is the Valve Gear of Engine. This valve drive system includes a camshaft supported by the cylinder head, featuring multiple cams with varying valve lift characteristics. A rocker shaft, also supported by the cylinder head, allows for the swingable support of a rocker arm. The rocker arm is strategically positioned between one of the cams and either an intake or exhaust valve, enabling axial movement. The presser of the rocker arm extends in the axial direction and is designed to be longer than the interval between the cams, ensuring effective valve operation.
