摘要： The invention relates to a method for controlling a turbocharger system (10) fluidly connected to an exhaust manifold (102) of a combustion engine (100). The turbocharger system comprises a tank (40) with pressurized gas, and a turbocharger turbine (22) operable by exhaust gases from the exhaust manifold. The tank is fluidly connectable to the turbocharger turbine. The method comprises the steps of: determining a first operational mode in which zero fuel, or only a predetermined low amount of fuel, is injected to the combustion engine, for a predetermined time period; and, after the predetermined time period, injecting pressurized gas from the tank to drive the turbocharger turbine, such that the turbocharger turbine is activated by the pressurized gas.

摘要： A two-cycle motor (10) has cylinder assembly (20) housing piston assembly (30) therein that moves reciprocally between two extreme positions controlled by a crankshaft. Cylinder assembly (20) includes combustion chamber (25) and an air compression chamber (45) in an enlarged annular portion (40). Portion (40) receives flange (31) integrally and radially outwardly extending from piston assembly (30) to define to air compression sub-chambers (47;47a). One-way inlet valve assemblies (41, 42) alternate to allow air in while outlet one-way valve assemblies (41a-42a) supply the compressed air to tank assembly (80) for release of the compressed air through intake one way valve assembly (29) to combustion chamber (25).

摘要： Methods and systems are provided for controlling airflow of an accumulator of a motorized vehicle. In one example, a method includes storing pressurized gases within the accumulator by flowing intake air from a compressor of an engine of the vehicle to a pressure booster arranged upstream of the accumulator. Pressurized gases stored within the accumulator may be used to drive one or more pneumatic devices.

摘要： A turbocharger system (1) of a combustion engine (4) comprises a turbocharger turbine (5) operable by exhaust gases, a valve (7) configured to control gas flow of pressurized gas from a pressurized gas reservoir (6) to the turbocharger turbine (5), and a sensor (8). Turbocharger system operation comprises injecting a test pulse of pressurized gas from the pressurized gas reservoir (6) to drive the turbocharger turbine (5) by means of controlling the valve (7), detecting an impact of injected pressurized gas on the turbocharger turbine (5) by means of the sensor (8), collecting data from the sensor (8), and diagnosing the turbocharger system (1) by evaluating an operational response of the turbocharger turbine (5) as a result of the injected test pulse of pressurized gas, based on the collected data.

摘要： Methods and systems are provided for a boosted internal combustion engine. In one example, a system may include an intake system for supplying charge air, a compressor arranged in the intake system, a first shut-off element arranged in the intake system upstream of an impeller of the compressor, a bypass line that branches off from the intake system upstream of the first shut-off element and that rejoins the intake system upstream of the impeller, a second shut-off element arranged in the bypass line, a compressed air line that opens into the bypass line downstream of the second shut-off element, and a third shut-off element arranged in the compressed air line. A map width of the compressor may be increased by providing airflow to the impeller via the bypass line during low mass flow conditions, and impeller acceleration may be expedited by providing compressed air via the compressed air line.

摘要： Methods and systems are provided for using a forced induction system as a source of compressed air to pressurize a portable pressure vessel for inflating tires. In one example, a method may include providing instructions to the operator to initiate the method which includes the operator coupling the portable pressure vessel to a connection port included on the induction passage of the induction manifold. Responsive to more than one operator input, a controller selectively opens a pick-up valve in the connection port, and operates a plurality of engine systems to boost pressure in the induction passage to fill the portable pressure vessel.

摘要： Systems and methods are disclosed that include operating an isothermal compression based combustion (IsoC) engine by injecting isothermally compressed air into a combustion engine immediately prior to a combustion event in order to increase the efficiency of the engine, improve emissions, and substantially eliminate autoignition and associated design constraints. The IsoC engine utilizes an intercooled compressor to isothermally compress air that is stored in a plurality of capacitance tanks prior to delivery of the compressed air to the combustion engine. The IsoC engine allows combustion to be selectively terminated to increase fuel efficiency, thereby resulting in a hybrid compressed air-motor and internal combustion operated IsoC engine.
