摘要： A supercharging pressure control system for an automotive engine with a supercharger controlling a pressure of incoming supercharging air into the automotive engine. The pressure of the incoming supercharging air is feedback-controlled so as to reach a target pressure of supercharging air which is determined depending upon engine operating conditions. A feedback control gain is varied higher when the incoming supercharging air pressure is higher than the target supercharging air pressure when compared to being lower than the target supercharging air pressure.

摘要： A variable compression ratio rotating engine comprises a containing cylinder forming variable volume chambers, defined by the cylinder inner wall and piston side walls, the cross-section of which has substantially the shape of a circle sector. During the operation of the engine, the pistons are rotated with an uneven circular motion, by a mechanism including a crank, having an eccentric axis with respect to that of the containing cylinder, and small coupling rods coupling the arms of the crank and the end portions of small shafts passing through the pistons, the compression ratio being changed by means of a further mechanism able of changing the eccentricity value of the crank axis with respect to the cylinder axis.

摘要： An improved "Wankel-type" rotary engine wherein the same trochoidal cavity employed for effecting a four-phase internal combustion engine operation is also employed to perform a supercharging function in that air is compressed in one chamber (chambers being defined between seals of the rotor with the wall bounding the trochoidal cavity) and transferred to another chamber in synchronization with the latter making its transition from its intake to its compression phase, with such transference being carried out in a manner causing substantial turbulence. The engine can optionally be operated in a diesel mode with diesel fuel injection being made at the conventional phase condition, or as a spark ignition engine with gasoline carburetion of air fed to the supercharging compression chamber being effected. Engine exhaust heat is optionally applied to compressed air or air-fuel mixture as the latter is being transferred respectively in the diesel or spark mode of engine operation. All air inlets to the engine are valved to controllably limit the effective compression ratio. Internal engine valving or porting is effected by a side of the rotor covering and uncovering openings in a side wall defining a side of the trochoidal cavity.

摘要： A radial internal combustion engine having a rotor of the radially movable vane type eccentrically housed within a rotor chamber casing both of which are journalled for rotation within an engine housing. Combustion induced rotation of the rotor is coupled by a gear train to the rotor chamber casing for driving the rotor chamber casing at the same speed as the rotor. Impeller blades provided on the periphery of the rotor chamber casing are employed to supercharge the fuel mixture prior to its being directed into the volumetrically expandable and contractable combustion chambers provided about the periphery of the rotor.

摘要： Internal combustion engine includes a rotary oxidizing gas compressor, a constant volume combustion chamber with pneumatically controlled intake and exhaust valves and a fuel injector, and a rotary combustion gas expander. Each of the rotary compressor and rotary expander has a pair of tangential rotors dependently rotatable in a housing, one rotor having a vane and the other a notch for allowing passage of the vane, to form a fluid tight segmented annular region through which the vane moves. The respective one of the intake valve and the exhaust valve admits a mass of high pressure compressible fluid to the region through a triangular port for expansion or from the region after compression, the mass of fluid being confined in a part of the region between the vane and the surface of the notched rotor and changing in pressure because of the change in arcuate length and volume of the confined part. The respective pairs of rotors are included on the same respective shafts. Two vanes may be included on the one rotor and two notches on the other. Two vaned rotors may cooperate with one notched rotor, the vaned rotors being on separate shafts.

摘要： A rotary internal combustion engine having an ellipsoidal wall member which forms an ellipsoidal internal chamber. A drive shaft is rotatably mounted in the housing and extends transversely through the ellipsoidal chamber. A substantially cylindrical rotor is secured to the drive shaft within the chamber and has a plurality of circumferentially equidistantly spaced vane members radially slidably disposed within the rotor. A source of fluid pressure communicates with the radially inner end of the vane members to urge the vane members radially outwardly so that the vane members contact selected circumferential sections of the wall portion. A fuel supply means including a rotary compressor supplies a fuel and air mixture to the rotor which thereafter further compresses the fuel between the rotor, the wall portion, and adjacent vane members. The fuel air mixture is ignited by appropriate ignition means to thereby rotatably drive the drive shaft.

摘要： An apparatus and method for improving the combustion process of an internal combustion engine is disclosed. A prechamber containing a combustible mixture is designed to generate a torch eminating therefrom upon ignition; the torch is controlled to extend and penetrate deeply into the main combustion at a predetermined orientation without contact with the chamber walls. The swirling flame front of the sustained torch produces superior mixing with the unburned combustible mixture in the main combustion, particularly of a rotary engine. The prechamber is located outside the epitrochoid chamber of the rotary engine; in a nonstratified charge mode of this invention, the prechamber serves to receive a portion of the main chamber inducted charge during the compression cycle, which may lean and difficult to ignite in the main chamber. In the prechamber, concentrated hot walls and a localized spark facilitate ready ignition, which in turn permits generation of a torch therefrom.A scavenging system and method is disclosed which serves to drive residual gas elements from the prechamber after the completion of each combustion cycle; the scavenging apparatus may be operated with an independent gas supply, a supply derived from the carburetor or intake of the engine, or from the inducted mixture within the main chamber. The scavenging system may have fuel enrichment to create a predetermined charge stratification.A fuel injection system and method is disclosed which serves to augment or act as the sole prechamber charge.Prechamber design, chamber shape, compression ratios and engine controls are arranged to reduce combustion heat losses and selected emission constituents.
