    摘要： A compressor active surge control system that includes an air recirculation line that has a first end connected downstream of a compressor outlet and a second end connected upstream of a compressor inlet. The gas recirculation line recirculates compressed air from the compressor outlet to the compressor inlet. Also included in the system is a mixer positioned to receive both ambient air and recirculated air. Mixing of the air homogenizes the air prior to its introduction into the compressor. An air cooler may be included that cools the recirculated air prior to its introduction into the compressor. Cooling and mixing of the recirculated air expands the operating range of the compressor by reducing the incidence of surge. Various existing components, such as intercoolers and filters, may serve the additional duty of cooling or mixing the recirculated air.

    摘要： The invention relates to an internal combustion engine which is provided with a manifold from which an intake tube extends to an intake of a cylinder of the internal combustion engine, with a gas inlet valve, disposed at the intake of the cylinder, an intermittent charge valve, disposed upstream of the gas inlet valve in the intake tube and releasing or closing the intake tube subject to a switching position of the intake tube, and in injection valve for metering fuel. The temporal position of the duration of injection of the fuel is adjusted subject to a point in time at which the switching position of the intermittent charge valve is changed. In this manner, it can be ensured that the air has a high velocity of flow during injection, thereby obtaining a good mixture preparation in a simple manner.

    摘要： The object of the present invention is to provide a controller, for a combustion engine, having a simple structure and which can reduce the exhaust emissions at the engine start-up time. The controller comprises a means for decreasing the pressure in an intake air passage downstream of a throttle valve during the engine cranking operation. A controller comprises an air pump, a means for communicating an inlet of the air pump either to the atmosphere or to an intake air passage downstream of a throttle valve, and a means for changing the inlet of the air pump from the atmosphere to the intake air passage downstream of the throttle valve and to activate the air pump during the engine cranking operation. Another controller comprises a vacuum tank, for example, a brake-booster instead of the air pump that enables it to more quickly reduce the air pressure in the intake air passage downstream the throttle valve.
