| 20110088667 | Supercharger Rotor Shaft Seal Pressure Equalization - A pressure equalization system reduces or eliminates a pressure differential across supercharger rotor shaft seals. Under high boost, rotor shaft seals often fail, allowing hot compressed air into an oil lubricated space containing rotor bearings and gears (and vented to ambient pressure), reducing oil lubricating effectiveness and resulting in increased wear and failure. Under low or non boost operation, the pressure differential is reversed causing the lubricating oil to leak into the supercharger interior and accelerated rotor seal wear. The pressure equalization system includes flow restrictive seals on both rotor shafts, separated from the rotor shaft seals by vented spaces, thereby isolating the rotor shaft seals from boost or vacuum in the supercharger interior and reducing or eliminating the pressure differential across the rotor shaft seals. Maintaining close to atmospheric pressure on both sides of the rotor shaft seals during boost and vacuum operation reduces wear and failures. | 04-21-2011 |

| 20120103310 | APPARATUS FOR CONNECTING INTAKE AND EXHAUST VALVES FOR INTERNAL COMBUSTION ENGINE - The present invention relates to reduction of compression space and improvement of intake/exhaust efficiencies through structural modification of a booster cylinder that delivers an explosive exhaust pressure generated during an exhaust stroke of one cylinder in a multi-cylinder internal combustion engine to an intake pressure of another cylinder, to minimize frictional heat and abrasion due to the reciprocating motion of a piston of the booster cylinder, and to endure a damping force by an air pocket when the piston of the booster cylinder moves toward the exhaust side. The apparatus for connecting intake and exhaust valves for internal combustion engines according to the present invention comprises: a plurality of cylinders such that when one cylinder is on an exhaust stroke, at least another cylinder synchronously performs at least part of an intake stroke; a pressure delivery pipe for connecting an exhaust manifold of one of the plurality of cylinders to an intake manifold of another cylinder; a booster pump installed in the pressure delivery pipe, wherein the booster cylinder, in which the piston of the booster pump is reciprocally and movably embedded, is comprised of a head having a first through-hole communicating with the intake side of the pressure delivery pipe and a recess for reducing the compression space as the piston moves toward the intake side, and a body fixed to the head, the body having a second through-hole communicating with the exhaust side of the pressure delivery pipe. | 05-03-2012 |
| 20120312282 | PRESSURE-WAVE SUPERCHARGER, AND METHOD OF OPERATING A PRESSURE-WAVE SUPERCHARGER - A pressure-wave supercharger for a combustion engine of a motor vehicle includes a first channel for drawing fresh air, a second channel for discharging compressed fresh air, a third channel for supply of exhaust gas, and a fourth channel for discharging exhaust gas. A hot-gas housing receives exhaust from the third channel for discharge through the fourth channel, and a cold-gas housing receives fresh air from the first channel and discharges compressed fresh air through the second channel. Disposed between the hot-gas housing and the cold-gas housing is a cell rotor housing which has a cell rotor. A guide element is arranged in at least one of the first and third channels to guide a gas flow for accelerating or decelerating the cell rotor. | 12-13-2012 |
| 20130037008 | PRESSURE WAVE SUPERCHARGER - The pressure wave supercharger includes a housing having an accommodating room to accommodate a rotor rotatably about an axis, and an exhaust side wall face which is arranged at the accommodating room as being opposed to one end face of the rotor and to which an exhaust gas introduction port and an exhaust gas discharge port are opened, and the rotor includes a shaft portion supported by the housing rotatably about the axis, plural partition walls arranged as being extended in the radial direction from the shaft portion and in the axial direction from the one end face to other end face of the rotor, and a partition member which is arranged at a space between adjacent partition walls and which partitions the space into an inner cell and an outer cell as extending from the one end face to the other end face of the rotor, and an exhaust side groove portion concaved in a direction being apart from the rotor is formed at the exhaust side wall face as being overlapped with a trajectory of the partition member lined during rotation of the rotor as viewed from the axial direction. | 02-14-2013 |
| 20130291841 | TWO-STROKE ENGINE AND FOUR-STROKE ENGINE - An exhaust gas exhausted from a combustion chamber of a two-stroke engine is fed to a turbine of a supercharger. Part of the exhaust gas that has passed through the turbine is extracted as an EGR gas by an exhaust gas recirculation part. The EGR gas is cooled by the heat of vaporization of liquid ammonia ejected from an ammonia ejection part, circulated into a suction gas in a suction path, pressurized by a compressor, and supplied as a scavenging gas into the combustion chamber. This recirculation of the exhaust gas can reduce the amount of nitrogen oxide exhausted from the two-stroke engine into the ambient air. Ejecting the liquid ammonia toward the EGR gas in a recirculation path facilitates cooling of the EGR gas, which is required for circulating the EGR gas into the suction gas. | 11-07-2013 |
| 20150107564 | INTERNAL COMBUSTION ENGINE, VEHICLE EQUIPPED WITH SAME, AND CONTROL METHOD THEREFOR - A supercharger and a turbocharger are provided, as well as a load sensor detecting a traction load of a trailer towed by a semi-trailer and being arranged in a coupler. A combined supercharging and turbocharging is performed by the supercharger and the turbocharger when the traction load is heavier than a previously defined traction determination value. Only supercharging is performed by the turbocharger when the traction load is not more than the traction determination value. | 04-23-2015 |
| 20150345410 | SUPERCHARGED APPLIED IGNITION INTERNAL COMBUSTION ENGINE WITH EXHAUST-GAS TURBOCHARGING AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF SAID TYPE - A turbocharged internal combustion engine is provided with at least a partially variable valve train on an intake side wherein the intake valves are controlled to optimize the actuation of a second inlet valve in relation to a first inlet valve for different load conditions. | 12-03-2015 |
| 20160123255 | CONTROLLER - A controller calculates a specific humidity of an intake air based on a relative humidity of the intake air, an intake air temperature, and an intake air pressure. Then the controller calculates a water vapor amount in the intake air based on the specific humidity and a mass flow rate of the intake air obtained from an air intake rate. By calculating the water vapor amount in the intake air based on information that directly represents the status of the intake air, this water vapor amount may be calculated more accurately. As a result, a generation amount of condensed water may be estimated more accurately. Therefore, accumulation of condensed water may be suppressed while recirculating as much of a low pressure exhaust gas as possible, and thus fuel economy may be sufficiently improved. | 05-05-2016 |
| 20160146120 | CONTROLLER FOR VARIABLE VALVE MECHANISM - An internal combustion engine is provided with a plurality of cylinders, air intake valves provided to each of the cylinders, and a variable valve actuation mechanism for varying the valve actuation of the air intake valves. A motor drives the variable valve actuation mechanism. A motor controller controls the motor. The internal combustion engine is capable of operating in a cylinder deactivation mode, in which the air intake valves of some of the cylinders are kept shut. When the internal combustion engine is reactivated from the cylinder deactivation mode, the motor controller executes an air intake amount correction process, in which the opening duration of the air intake valves is temporarily increased, thereby increasing the amount of air taken in by operating cylinder for which the air intake valves have been opened or closed even during the cylinder deactivation mode. | 05-26-2016 |
