摘要： The invention relates to a spark ignition engine (1) having a pressure-wave supercharger (5) and a three-way catalyst (4). To remove the pollutant constituents HC, CO and NO.sub.x in an efficient manner, an oxidation catalyst (12) is connected downstream of the three-way catalyst, said oxidation catalyst being arranged between the outlet of the supercharger and the exhaust (11). The oxidation catalyst can, consequently, function with excess air which comes from the supercharger. The above combination reduces pollutants substantially with a high specific output of the engine.

摘要： Flanged onto the air casing (6) of a free-running pressure wave supercharger for an internal combustion engine is an electric motor (10a) whose shaft (28) is effectively connected to the rotor shaft (8) via a free-wheel overrunning clutch (9a) with engagement rollers (27) as the engagement bodies. In order to start a supercharged internal combustion engine, the electric motor (10a) accelerates the cell rotor (2) (in the case of a diesel engine, for example, during the short preheating period) to a rotational speed which ensures a functioning pressure wave process immediately after the diesel engine starts. The cell rotor (2) is then further accelerated by the exhaust gases of the diesel engine and then releases itself from the drive connection with the electric motor (10a), which has been put out of operation in the meantime.

摘要： In a free-running pressure wave supercharger driven by the gas forces, nozzles (27) are provided in the gas casing (6) and possibly also in the air casing (5), which nozzles are connected--via a drive line (26)--with a position in the air casing (5), preferably with the high-pressure air port (2), at which position a surplus pressure relative to the nozzle entry occurs during the run-up phase of the pressure wave supercharger. A control device 15 actuates a supercharge air flat (14) in the port (2) and a valve device (23+25) in the drive line (26) in the opposite sense, i.e. if the supercharge air flap (14) holds the port (2) closed, the valve device (23+25) frees the flow through the drive line (26) to the nozzle (27) and vice versa. The diaphragm capsule (17) of the control device (15) is subjected, on one side, to the pressure in a compression pocket (11) via a control pressure line (19) and, on the other side, to the pressure before the supercharge air flap (14) in the port (2). During the run-up phase, the pressure in the compression pocket (11) exceeds the pressure in front of the supercharge air flap (14) and the nozzle (27) receives drive air. As soon as the pressure in front of the supercharge air flap (14) exceeds the pressure in the compression pocket (11), the supercharge air flap (14) opens and simultaneously closes the valve device (23+25). The nozzle (27) is switched off and the further drive is then mainly provided by the high-pressure exhaust-gas jet from the port (3) entering obliquely to the direction of the rotor peripheral velocity.

摘要： An exhaust plenum chamber for a supercharged engine having a variable volume. A mechanical spring is arranged to an exhaust plenum chamber to increase the spring action of the plenum chamber volume. In this connection, the plenum chamber interior is divided into a flow chamber and a dead volume. The efficiency especially of relatively small plenum chambers in internal combustion engines with a small number of cylinders and/or slight supercharging is improved.

摘要： An engine intake system including a supercharger of a type wherein the intake air drawn from the intake air inlet port is compressed by the pressure of the exhaust gas before it is discharged through the intake air outlet port. An exhaust gas recirculation passage is provided between the exhaust passage upstream of the supercharger and the intake passage downstream of the supercharger. The recirculation passage can be used for decreasing the pressure difference between the exhaust gas and the intake air to thereby minimize the engine pumping loss. Further, the recirculation passage can be used for recirculating the exhaust gas to the intake passage to thereby decrease nitrogen oxides in the exhaust gas.

摘要： An exhaust gas blow-down valve of a pressure wave supercharger comprising a flap which is connected by a flap lever, a flap shaft and a second lever to a control device responsive to a process pressure of the pressure wave supercharger. In order to avoid deterioration of the scavenging coefficient of the pressure wave supercharger, a restraining screen is provided around part of the periphery of the flap at a distance from it, which restraining screen deflects the exhaust gas flowing out of the flap gap into the desired direction parallel to the axis of the exhaust gas outlet stub pipe.
