Improvements relating to rotary-piston internal combustion engines

... 1,144,038. Rotary-piston internal combustion engines. DAIMLER-BENZ A. G. May 12, 1967 [May 13, 1966], No.22195/67. Heading F1F. A rotary-piston I. C. engine of trochoidal type having peripheral exhaust and admission ports 4, 5 includes a bore 11 opening into the admission port 5 adjacent the piston track 2 and downstream of an air flap 8 through which air or fuel-air mixture is blown to form a barrier between the exhaust and admission ports to prevent exhaust gases being mixed with the fresh fuel-air mixture.

The locating of the bore 11 and nozzle 9 so that they open in a direction opposite to piston rotation produces good mixture formation and turbulence to ensure efficient burning of the fuel.

A hydrogen-fuelled rotary engine and improvements relating thereto

A Wankel-type rotary engine using a pressurised-air rotor cooling system incorporating a rotary valve 7 for injecting Hydrogen (H2) gas early in the compression stroke into the engine compression chamber 48. The high flow rate valve allows use of low H2 supply pressure. The homogeneous mixture with near 100% excess air results in zero NOx emissions. A small quantity of lubricant is directly metered to the three rolling element bearings such that carbon emissions are also negligible. The single-rotor engine operates only at a single speed and is unthrottled. A turbo-compound unit 11 installed adjacent to the single exhaust port 47 gathers further energy. The combination of low mechanical friction and pumping losses, fast and complete combustion with H2 fuel, and a gas sealing system using precision-machined slots possessing small clearances results in high thermal efficiency power units suitable for operating as lightweight range extenders in electric-motor-driven sea, land and air vehicles ...

INTERNAL COMBUSTION ENGINE WITH ROTARY PISTON INJECTION OF THE TROCHOIDE TYPE

La présente invention concerne un moteur à combustion interne à injection à piston rotatif du type en trochoïde. Ce moteur comprenant un premier injecteur dans l'enveloppe 1 et un second injecteur dans un canal d'admission se caractérise en ce que le premier injecteur 11 est disposé en un emplacement de l'enveloppe 1 qui se situe toujours dans la zone de la chambre de travail A aspirante et est configuré en injecteur à chemise d'air. Un dispositif de dosage de carburant 18 injectant une quantité de carburant proportionnelle à la quantité d'air aspiré, est relié en permanence avec le premier injecteur il tandis qu'un dispositif de commande 23 relie le second injecteur 15 au dispositif 18 à partir d'un régime de charge partielle déterminé jusqu'à la charge maximale. L'invention permet d'améliorer la préparation du mélange carburant-air. The present invention relates to a rotary piston injection internal combustion engine of the trochoidal type. This engine comprising a first injector in the casing 1 and a second injector in an intake duct is characterized in that the first injector 11 is arranged in a location of the casing 1 which is still located in the area of the chamber. A suction workpiece and is configured as an air jacketed injector. A fuel metering device 18 injecting a quantity of fuel proportional to the quantity of air sucked in, is permanently connected with the first injector 11 while a control device 23 connects the second injector 15 to the device 18 from a determined partial load regime up to maximum load. The invention makes it possible to improve the preparation of the fuel-air mixture.

Method and system for non-functional combustion chamber detection

Systems and methods for detecting at least one non-functional combustion chamber of an engine comprising a plurality of combustion chambers are described herein. In response to detecting a partial output power loss of the engine, one of the plurality of combustion chambers is assessed by monitoring an engine parameter indicative of an output power of the engine, determining whether a change in the engine parameter has occurred, when the change has occurred, determining that the combustion chamber is functional, and when no change has occurred, determining that the combustion chamber is non-functional and discontinuing fuel injection to the non-functional combustion chamber.

High compression rotary piston IC engine - has eccentric with greater eccentricity than shaft carrying it

The high compression rotary piston i/c engine using e.g. air compression with a static cover has an inner surface similar in cross-section to a rotary piston machine with a double-arched epitrochoid. An eccentric shaft is fitted vertically to side parts, and on its eccentric a triangular rotary piston is fitted. The speed of the piston is maintained by a gear at a fixed ratio to that of the eccentric shaft. The cover inner surface has a vaulted part in the shape of an arch in the area of compression, and the eccentricity of the eccentric (12) is greater than that of the eccentric shaft (9).

Internal combustion engine control system

Patent FR2177388A5

Hybrid cycle rotary engine

An internal combustion engine includes in one aspect a source of a pressurized working medium and an expander. The expander has a housing and a piston, movably mounted within and with respect to the housing, to perform one of rotation and reciprocation, each complete rotation or reciprocation defining at least a part of a cycle of the engine. The expander also includes a septum, mounted within the housing and movable with respect to the housing and the piston so as to define in conjunction therewith, over first and second angular ranges of the cycle, a working chamber that is isolated from an intake port and an exhaust port. Combustion occurs at least over the first angular range of the cycle to provide heat to the working medium and so as to increase its pressure. The working chamber over a second angular range of the cycle expands in volume while the piston receives, from the working medium as a result of its increased pressure, a force relative to the housing that causes motion of the piston relative to the housing.

Rotary internal combustion engine

A rotary engine according to the present invention comprises a main housing assembly and a rotor assembly rotatably supported within the housing. The rotor assembly has two rotors, an intake/compression rotor rotatably disposed within the intake/compression housing, and a power/exhaust rotor rotatably disposed within the power/exhaust housing. The rotors have N number of apexes and sides, wherein N is an integer greater than 2. A rotating chamber is formed between each side of the each rotor and the inner wall of the respective housing. The stages of the thermodynamic cycle of the engine occur within these chambers. For example, if the rotors have three sides, the rotors will have a triangular-like shape with three apexes. The apexes form the outermost radial part of the rotors which engage the inner wall of the respective housing bore. Each of these chambers is split into two divided chambers by a reciprocating vane, thereby forming 2 times N divided chambers in each of the respective housing bores.
