    Abstract: 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.

    Abstract: A apparatus and method for adjusting the amount of air introduced into a cylinder of an internal combustion engine. An intake passage is connected to the cylinder for introducing air. An intake valve is provided in the intake passage for cyclically opening and closing the cylinder. An injector is provided in the intake passage for injecting fuel. A throttle valve is positioned in the intake passage for adjusting an amount of air flow into the cylinder. An electronic control unit (ECU) controls the position of the throttle valve. The ECU closes the intake passage to decrease the pressure in the intake passage when cranking is started. The ECU moves the throttle valve to a first open position .theta.2 to increase the amount of air introduced into the cylinder after a predetermined time period elapses from the start of engine cranking. The ECU moves the throttle valve to an open position .theta.1 when the engine starts.
