Similarly, when the intake or exhaust valve is opened, the opening solenoid is de-energized for a very short time immediately before the intake or exhaust valve is fully opened so as to reduce a travelling speed of the valve body when the valve body is fully opened. Noise is reduced and durability increased.

Electromechanical valve actuator

Method of controlling electronically controlled valves to prevent interference between the valves and a piston

Valve timing regime in an i.c. engine capable of operating in two-stroke mode

An internal combustion engine capable of operating in a two-stroke mode, has an engine control system 12 that acts on the valve actuating mechanism 14 to set an operating regime (Figure 3) in which the timings of the intake and exhaust valve events are, instead of being symmetrical about BDC, both advanced to such an extent that, during each rotation of the engine crankshaft, the major proportion of each event occurs during the second half of the piston downstroke. Preferably at least two-thirds of the intake event occurs during the downstroke. As a result, while both valves are open the combustion chamber is increasing in volume and the resulting negative pressure draws air from the intake system into the combustion chamber, as in a conventional four-stroke engine. The valve actuating system 14 may be camless or may include a camshaft phase changer. The invention allows two stroke operation of a dual mode 2/4 stroke engine during starting and idling without pressurising the intake system ...

A computer controlled intake and exhaust valve for internal combustion engines having a microprocessor controlled, hydraulically operated, valve actuator with manually adjustable variable performance settings for improving fuel efficiency and reducing emissions while also providing a high performance power stroke and lengthening the life of the valve seat by damping the impact of valve reseating. The computer controlled intake and exhaust valve includes a) a semi-automatic engine braking feature whereby the compression of exhaust gases within the chamber of a cylinder prior to venting is used to aid in reducing the speed of the vehicle, thus prolonging the life of the brakes and the safety of passengers, and b) notched and stepped valve seats which aid in retaining compression within the combustion chamber.

VALVE OPERATING SYSTEM IN INTERNAL COMBUSTION ENGINE

An actuator is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft, so that the actuator can drive an engine valve in a lift amount which is obtained by addition of a lift amount of the engine valve based on a cam profile of the valve operating cam and a lift amount of the engine valve based on the operation of the actuator. Thus, a portion of the lift amount of the engine valve is borne by the valve operating cam, whereby a valve-opening power borne by the actuator can be reduced, as compared with a system designed so that the engine valve is driven by only the actuator only. The amount of electric power consumed by the actuator can be smaller.
