摘要： A variable displacement internal combustion engine having an intake manifold for providing ambient air and a boost manifold is provided. Either designated cylinders or selected cylinders may be operated in a non-firing mode wherein air may be compressed in a non-firing cylinder and ported to the boost manifold to provide boosted air pressure to firing cylinders. Each cylinder has an intake valve, an intake/compressed air valve, and an exhaust valve. The intake valves are controlled by electromagnetic actuators. The exhaust valve may be controlled by an electromagnetic valve actuator or a conventional valve actuator, if desired. Intake/compressed air valves of cylinders operating in the non-firing, compressor mode are ported to the boost manifold and selectively timed to provide compressed air to the boosted manifold when additional torque is desired provided that some of the cylinders are operating in the compressor mode.

摘要： Embodiments for routing exhaust in an engine are provided. In one example, an engine method comprises, during a first condition, firing a subset of cylinders and routing all exhaust from the subset of cylinders through a first exhaust manifold coupled directly to a catalyst and not a turbocharger, and during a second condition, firing all cylinders, routing a first portion of exhaust through a second exhaust manifold coupled to the turbocharger, and routing a second portion of exhaust through the first exhaust manifold. In this way, exhaust can be directly routed to a catalyst under some conditions.

摘要： A supercharger compressor includes a plurality of rotors rotatably mounted in a housing, a first inlet for air, a second inlet for recirculated exhaust gas, and a flow separator. The flow separator is arranged interior the housing and configured to form a slideable seal with at least one rotor of the plurality of rotors, the slideable seal fluidically isolating the first inlet from the second inlet, at least in part, and retarding pressure equalization therebetween.

摘要： A strategy and control system for a variable displacement engine in which cylinder deactivation is obtained by intake cam phasing and exhaust valve deactivation. Fuel control for the engine and spark deactivation are sequenced with valve deactivation to avoid transferring engine exhaust gases to the intake manifold of the engine during a transition between full cylinder operation and partial cylinder operation. Excess air flow through the exhaust system for the engine is avoided during a transition from partial cylinder operation to full cylinder operation. These features achieve stable engine performance during the transition.

摘要： A method for controlling combustion in a cylinder of a turbocharged engine in which intake air is reserved upstream of the cylinder. The method comprises decreasing an internal EGR rate in the cylinder during a tip-out condition if the temperature of the intake air is above a threshold, and increasing the internal EGR rate in the cylinder during a tip-out condition if the temperature of the intake air is below the threshold.
