摘要： A closed loop control system for an exhaust gas recovery flow in an internal combustion engine having an intake air pressurizing device is provided. The closed loop control system includes an engine controller connected to an intake air mass flow sensor, an engine operation sensor, and an intake air throttle valve for controlling the intake air mass flow rate. In addition, the controller is operatively connected to a variable gas pocket valve for selectively controlling exhaust gas feedback in conjunction with the intake air throttle valve. The variable gas pocket valve and the intake air throttle valve may be actuated in response to the control system parameters to provide accurate control of exhaust gas recovery flow to provide reduced emissions of unburned fuel and particulate matter from the engine.

摘要： In the case of a gas-dynamic pressure-wave supercharger for the supercharging of an internal combustion engine, an exhaust bypass in the gas housing (2), with a medium-controlled gate, connects the high-pressure gas inflow duct (4) to the low-pressure gas outflow duct (6). The exhaust gas blown off is introduced via a waste gate ejector (33), which is located in the region of the closing edge (30) in the low-pressure gas outflow duct (6), into the latter. Consequently, the energy level of the low-energy scavenging air can be increased, which improves the compression efficiency of the pressure-wave supercharger.

摘要： In an internal combustion engine supercharged by a pressure-wave supercharger (2), a lambda probe (7) is used for measurement of the oxygen content in the circuit. The oxygen content determined by the lambda probe (7) creates a measuring signal (9), which is used for controlling the throttle valve (4) and/or the starting valve (6). This control is aimed at reducing the NO.sub.x emissions from the combustion and possibly ensuring the regeneration of an exhaust gas particle filter (3) integrated in the circuit. In this arrangement, the lambda probe (7) is to be placed in the low-pressure exhaust gas line (444), which has a positive effect on the response capability and the accuracy of the measured data of the probe (7). This obviates the need for additional aids for the correction of pressure fluctuations such as occur at other points in the circuit of the internal combustion engine.
