摘要： An engine is operated in accordance with a plurality of operation modes obtained by combining one of a 4-cycle mode and a 2-cycle mode with one of a combustion ignition control where an ignition is performed with an ignition unit and a self ignition priority control including the ignition performed without the ignition unit. Upon switching of the operation mode, a transition cycle is performed once between a first operation mode before switching of the operation mode and a second operation mode after switching of the operation mode. Timing for operating an intake valve or an exhaust valve in the transition cycle is different from that in the second operation mode. The combustion ignition control is executed in one of the combustion chambers where the single operation of the transition cycle is completed until a single cycle of each transient cycle in the rest of the combustion chambers is terminated.

摘要： A dynamically re-configurable multi-stroke internal combustion engine, comprised of programmable computer processor controlled engine components for decoupling the four classic strokes of an internal combustion engine and electronically managing engine cylinder components including such cylinder components as electronically controllable valves, fuel injection and air fuel mixture ignition, allowing additional engine cylinder unit component states and thus cylinder strokes to be independently altered or re-sequenced by computer control to provide alternate engine modes of operation. Some alternate engine modes are facilitated by addition of a compressed air storage reservoir to receive cylinder generated compressed air or transfer compressed air to cylinder units in other modes to increase engine power, efficiency or utility. Sensor input and on-demand requirements drive control logic to manage engine strokes through control of individual cylinder component states. Dynamic reconfiguration of individual component states provides re-generative engine energy modes, boost power modes, and mixed modes which use compressed air stored energy re-introduced for alternate cylinder state sequences and alternate engine modes of operation which add utility and efficiency to otherwise fixed sequence multi-stroke power generation in internal combustion engines.

摘要： An engine is selectively operable in two- and four-cycle modes by varying the timing to open and close intake and exhaust valves on the top of a cylinder. The engine comprises first and second valve actuating mechanisms for opening and closing the intake and exhaust valves, a selective operating mechanism for operating the first valve actuating mechanism to open and close the intake and exhaust valves while the second valve actuating mechanism is disabled, and for operating the second valve actuating mechanism to open and close the intake and exhaust valves while the first valve actuating mechanism is disabled, and a rotation transmitting mechanism for transmitting rotation of a crankshaft of the engine, each time the crankshaft makes two revolutions, to the first valve actuating mechanism through the selective operating mechanism when the engine operates in the four-cycle mode, and for transmitting rotation of the crankshaft, each time the crankshaft makes one revolution, to the second valve actuating mechanism through the selective operating mechanism when the engine operates in the two-cycle mode. The rotation transmitting mechanism starts to transmit rotation of the crankshaft to the first and second valve actuating mechanism when the crankshaft has been angularly moved through a predetermined angle.

摘要： This cycle changeable engine includes first intake valves for a four-cycle operation which are disposed in intake ports formed in a cylinder head, exhaust valves disposed in exhaust ports, second intake valves for a two-cycle operation, disposed in intake ports formed at the lower part of a cylinder, and an electromagnetic valve driving device for opening and closing each of the valves by electromagnetic force. The engine includes also a controller which actuates either the first or second intake valves for opening and closing with the others being kept closed in response to a detection signal from detection means for detecting the number of revolutions or load of the engine, and changes the operational condition of the engine to the two-cycle or four-cycle operation. In this manner the engine is operated in the two-cycle operation at a low speed revolution of the engine to improve an output torque and is operated in the four-cycle operation at a high speed revolution of the engine to reduce fuel consumption, to improve mean effective pressure and volume efficiency and to reduce noise.

摘要： A method of and apparatus for starting and accelerating a vehicle through a range of vehicle speeds during which the vehicle's internal combustion engine is operated in a plurality of different operating modes is disclosed. The engine may first be cranked in a compressionless mode preparatory to starting and then run in a second mode at a relatively low speed for a warm-up interval as a six-stroke cycle engine where each engine cylinder cycle includes an essentially adiabatic compression and expansion. The system may then convert to a third mode of operation as a four-stroke cycle engine during normal engine operation. Different operating modes are available during this normal engine operation. Under high demand conditions, the engine may be run as a conventional inefficient but effective throttled engine or converted to operate in a fourth mode as a two-stroke cycle engine. The system responds to second engine conditions to modify the parameters in a memory table and controls the vehicle in accordance with the parameters stored in the table. Both short term modification to accommodate dynamic changes in the sensed engine conditions and long term modification to compensate for relatively slow changes in the engine and the management system are made to the information in a random access memory. The modifications may be on an overall engine basis or an individual cylinder basis.

摘要： The invention relates to a thermal engine provided with inlet and exhaust valves and with a system for controlling said engine comprising a computer which regulates opening and closure of said valves and which imposes on said engine an operation close to the one corresponding to minimum specific fuel consumption. According to the invention, this assembly is characterized in that said engine is essentially of the four-stroke cycle type, in that said system comprises means adapted to detect overloads of the engine and means adapted to cause the engine to operate exceptionally in two-stroke mode, these latter means being actuated by said detection means when the detected overload exceeds a predetermined threshold so that in that case the engine passes to two-stroke operation, four-stroke operation being resumed as soon as the overload has disappeared. The invention leads to obtaining a low consumption of fuel for increased power.
