    摘要： The gas-dynamic pressure wave machine, which is destined for the charge air supply of an internal combustion engine, comprises a rotor, a low pressure fresh air inlet channel, a high pressure charge air channel leading to the internal combustion engine, a high pressure exhaust channel coming from the internal combustion engine, and a low pressure exhaust channel, the low pressure exhaust channel and the high pressure exhaust channel being enclosed in a gas enclosure and the low pressure fresh air inlet channel and the high pressure charge air channel being enclosed in an air enclosure. In order to obtain an improved efficiency in low flow rate and temperature conditions, the high pressure exhaust channel is enlarged on the rotor side without forming a ridge, and the size of the enlargement is variable. The use of a heating device acting upon the high pressure exhaust channel allows a further improvement of the cold start properties, without the need for an enlargement or gas pockets. A substantial improvement in efficiency is obtained by the individual use of each one of these measures.

    摘要： A pressure-wave supercharger for an internal combustion engine is incorporated into the engine flywheel. The supercharger includes a rotor with a plurality of cells extending axially of the rotor and arranged circumferentially about the rotor, an exhaust tube for introducing exhaust gas into the cells at one end of the rotor during rotation thereof, an ambient air inlet tube for introducing air into the cells at another end of the rotor during rotation thereof, the air introduced into the cells being compressed by the exhaust gas introduced into the cells. A compressed air inlet tube feeds the compressed air to the engine. The cells or channels of the rotor are formed within the flywheel itself such that the flywheel operates as the supercharger mechanism.

    摘要： A system and method for controlling an exhaust gas recirculation system in an internal combustion engine having two or more actuating devices on a supercharger-type pressure-charged internal combustion engine, or, in a turbocharger equipped pressure-charged internal combustion engine. In the disclosed embodiments, the actuating devices may include a variable gas pocket valve, an air intake throttle valve, an exhaust gas recirculation valve, a turbocharger back pressure valve, or the adjustable turbine blades in a variable gas turbine. In the disclosed embodiments, the control system includes a pair of actuators operatively coupled to an engine controller. The second actuator is operatively responsive to the first actuator when the first actuator command signal exceeds prescribed actuator limits. However, when the first actuator is commanded or operating within the prescribed actuator limits, the variance or feedback signal is zero and the second actuator operates more or less independently of the first actuator.

    摘要： The pressure wave supercharger of the internal combustion engine has a diaphragm capsule (20) for controlling the supercharge air butterfly (14). The diaphragm (21) of the diaphragm capsule is, in operation, subjected on the butterfly side to the high pressure air in the high pressure air duct (2) and on the other side to the pressure at the protrusion 27 or in the compression pocket (5), via a control pressure line (26; 28). These pressures typical of the process vary with the speed of the cell rotor and control the setting of the supercharge air flap as a function of the speed and loading condition of the engine.

    摘要： A method for supercharging internal combustion engines with turbochargers wherein the engine is operated in the lowest load region as a naturally aspirated engine, and the waste gate, the inlet section of the turbine and all other exhaust gas ducts present are fully open. When this load range is exceeded, the flow area of the turbine inlet is reduced to its minimum operational value and subsequently, with a further increase in load, is increased again to its maximum value at full load. The engine operated according to this method has a varioturbocharger whose turbine inlet flow area is controlled by a throttle slide as a function of the fuel injection quantity and the boost pressure by means of an adjustment device and a control pressure modulator.

    摘要： An actuator for an air valve placed in the boost air duct of an IC engine and, more specially, of such an engine supercharged or boosted by a pressure wave supercharger, the air valve being in its closed position on starting up the IC engine from cold, at which time the engine takes in charge air by way of a breather valve, and at the end of the starting stage the valve in the boost air duct is moved into its open position and is kept open while the engine is running. After shutting down the engine, the valve in the intake pipe is automatically moved back into its closed position and the air valve is moved into its open position by the pressure of the air forced into the boost air duct and/or by vacuum against an air valve spring closing force.
