| 20090145410 | Breathing for an internal combustion engine - In one aspect of the disclosure an internal combustion engine may be provided that may include a combustion chamber and a piston reciprocally moveable in the combustion chamber. The combustion chamber may have an intake port and a dual function port. The dual function port may be connected to an exhaust system and to an intake system. A method may be provided including opening a fluid connection between the intake system and the combustion chamber via the intake port as well as the dual function port during at least a part of an intake stroke of the piston. Instead of, or in addition, the method may include opening a fluid connection between the exhaust system and the combustion chamber via the dual function port during at least a part of the intake stroke of the piston. | 06-11-2009 |
| 20100288248 | HYBRID ENGINE - A hybrid engine that uses a primary internal combustion engine portion and a secondary external combustion engine portion. In a preferred arrangement, the secondary external combustion engine portion operates as a reciprocating steam engine. The heated exhaust gases of the internal combustion engine portion are used to generate steam, and the steam is used to power the steam engine portion adding the steam engine's power output to that of the internal combustion engine. The thermal efficiency of the hybrid engine may be higher than the thermal efficiency of an internal combustion engine without use of the exhaust gas heat. The hybrid engine uses a configuration in which steam is generated directly in the steam engine and a mechanical link between the internal combustion engine portion and the steam engine portion with the result that the hybrid engine is simple and inexpensive to construct and maintain. | 11-18-2010 |
| 20130199505 | CYLINDER HEAD AND INTERNAL COMBUSTION ENGINE EQUIPPED THEREWITH - A cylinder head and internal combustion engine outfitted therewith, in which the cylinder head has a plurality of media passages, at least one of which is for conducting a corrosive medium. Each media passage has a media contact surface for conducting a medium. The cylinder head has a longer service life due to the media contact surface of the at least one media passage for conducting the corrosive medium being formed of a corrosion-resistant material. | 08-08-2013 |
| 20130206121 | ENGINE - An engine includes an EGR apparatus which refluxes a portion of exhaust gas from an exhaust manifold to an intake manifold as EGR gas. A differential pressure sensor detects a differential pressure between intake pressure of the intake manifold and exhaust pressure in the exhaust manifold. The differential pressure sensor is mounted on a head cover which covers an upper portion of a cylinder head. An intake pressure taking-out passage which is in communication with the intake manifold is formed in the cylinder head. An intake pressure introducing passage which is connected to the differential pressure sensor is formed in the head cover. The intake pressure taking-out passage and the intake pressure introducing passage are in communication with each other. | 08-15-2013 |
| 20140014078 | ENGINE INCLUDING INTERNAL EGR - An engine assembly includes an engine structure and an exhaust gas recirculation control valve supported on the engine structure. The engine structure defines a cylinder bore and intake and exhaust ports in communication with the cylinder bore. An internal exhaust gas recirculation passage is defined in the engine structure and extends from the exhaust port to the intake port and may overlie a central region of the cylinder bore. The exhaust gas recirculation control valve is at least partially located within the internal exhaust gas recirculation passage and is displaceable between an open position and a closed position. The open position allows exhaust gas flow from the exhaust port to the intake port through the internal exhaust gas recirculation passage and the closed position obstructs exhaust gas flow from the exhaust port to the intake port through the internal exhaust gas recirculation passage. | 01-16-2014 |
| 20140290632 | Intake Gas Distribution Box For Use In An Engine, In Particular A Motor Vehicle Engine, And Gas Supply Module Comprising Said Box - An intake gas distribution box ( | 10-02-2014 |
| 20160061149 | ASSEMBLY WITH CYLINDER HEAD HAVING INTEGRATED EXHAUST MANIFOLD AND METHOD OF MANUFACTURING SAME - An assembly includes a cylinder head with an integrated exhaust manifold that has four exhaust flow passages directing cylinder exhaust from inlets arranged to correspond with exhaust from the four cylinders, respectively, and has only three outlets. The assembly includes a twin scroll turbocharger having a housing with a first scroll passage, a second scroll passage, and only three inlets. Two of the exhaust flow passages join in the cylinder head to direct exhaust flow into only one of the inlets of the housing and through the first scroll passage. Exhaust flow through the other two of the exhaust flow passages flows separately into the other two inlets in the housing and joins in the housing to flow through the second scroll passage. | 03-03-2016 |
