20100175377 | COOLING AN ELECTRICALLY CONTROLLED TURBOCHARGER - An electrically controlled turbocharger has a motor mounted on a shaft in a motor housing between a turbine and compressor. Oil is sprayed onto the motor stator to cool the stator. Flingers on the shaft fling oil back onto the stator. | 07-15-2010 |
20100284824 | Cooling an Electrically Controlled Turbocharger - An electrically controlled turbocharger has a motor mounted on a shaft in a motor housing between a turbine and compressor. Oil is sprayed onto the motor stator to cool the stator. An oil gallery is disposed above the stator to receive lubricating oil and contains apertures that perform as jets to allow oil to be sprayed directly on the motor stator. A coolant jacket is formed in the turbocharger housing between the turbine and the motor to allow liquid coolant to circulate therein and dissipate heat from the turbine end prior to reaching the motor components. Other embodiments provide for a stator component to be submerged in flowing cooling oil. | 11-11-2010 |
20100308685 | ELECTRIC MOTOR ROTOR - A rotor for use in an electrical motor which includes an anti-expansion ring centrally mounted on the rotor to restrict the extent rotor elements mounted on a rotatable shaft may expand outward due to centrifugal forces generated when the motor is operated. Such motors are suited for use in high rotational speed environments such as electrically controlled turbochargers. | 12-09-2010 |
20110057049 | Supercritical-State Fuel Injection System And Method - A fuel injector system for raising fuel to its supercritical state and injecting the supercritical-state fuel to the combustion chamber of an internal combustion engine is disclosed. A plurality of injector embodiments provides alternative ways to heat the pressurized fuel to its supercritical state. Injection of supercritical fuel into the combustion chamber is known to improve fuel entrainment and reducing ignition delay to thereby increase combustion rate, which leads to an increase in fuel efficiency. According to some embodiments, the system provides for preventing coking that may otherwise occur in an exhaust gas heat exchanger used for preheating the high pressure fuel. In other embodiments, engine cold start assistance is provided by storing pressurized, heated fuel in an insulated container. | 03-10-2011 |
20120192559 | Exhaust System for an Internal Combustion Engine - A combustion chamber of an internal combustion engine has at least a first and a second exhaust port, which are decoupled downstream of the combustion chamber. The first exhaust port is opened before the second exhaust port during an expansion stroke of the piston. The first exhaust port is coupled to a high-pressure turbine and the second exhaust port is coupled to a low-pressure turbine. By directing exhaust gases at higher pressure to the high-pressure turbine and gases at lower pressure to the low-pressure turbine, the overall energy recovery from the exhaust gases is greater than a system with one or more exhaust turbines coupled in series with all of the exhaust ports. | 08-02-2012 |
20120312271 | PISTON - A piston has a piston head, a piston pin support projecting from the piston head, and a mantle wall connected to the piston head. The mantle wall is formed with two tubular pieces that are disposed concentrically relative to one another and which are connected at a periphery of the piston head. A hollow space is formed between the tubular pieces. | 12-13-2012 |
20130087115 | OPPOSED PISTON ENGINE - An opposed piston engine has an outer piston and an inner piston, which are disposed in a cylinder and are driven in opposite directions and delimit a common combustion chamber. The inner piston drives a crankshaft via a connecting rod and the outer piston drives the crankshaft via a pair of traction connecting rods. The outer piston is supported by a connecting rod that is guided linearly in a guide block, and the connecting rod protrudes from a bridge that is connected at both end portions to a traction connecting rod. Accordingly, it is provided that each traction connecting rod contains a U-shaped curved piece of tube, preferably with parallel legs, which with its U-shaped curved portion encloses a part of the circumference of the pivot bearing supported by the bridge and is fixed, especially bolted, with its leg ends onto a traction connecting rod bearing mounted on the crankshaft. | 04-11-2013 |
20130087119 | ENGINE CYLINDER AND INTERNAL COMBUSTION ENGINE HAVING THE ENGINE CYLINDER - An engine cylinder has a feed duct and a charge movement duct, which are each led adjacent to one another to an inlet valve in the cylinder head of the engine cylinder. A through flow of the two ducts is regulated by a common throttle valve extending in the or over the two ducts or their inflow openings, with which the end portions of the two ducts remote from the combustion chamber or their inflow openings can be closed. | 04-11-2013 |
20130152781 | METHOD FOR MILLING A CYLINDER HEAD AND CYLINDER HEAD - A method for the machine-milling of intake and/or exhaust ducts formed in a cylinder head includes working off the inner wall surfaces of the intake and/or exhaust ducts at least in part, preferably completely, with a multi-axis, preferably five-axis, CNC-controlled cherry head in a stabbing movement. Grooves are thus formed in the inner wall surfaces that extend primarily in the flow direction of the ducts. | 06-20-2013 |
20140216246 | PISTON - A piston has a piston crown, a piston pin support that extends from the piston crown, and a skirt wall that is connected to the piston crown. The skirt wall has two tubular pieces which are concentrically arranged relative to each other and each of which is connected to the piston crown in the circumferential region of the piston crown. A hollow space cavity is formed between the tubular pieces and a coolant is disposed in the cavity. | 08-07-2014 |
