  • Patent number: 10415457
    Abstract: Techniques for setting a boost target for a turbocharged engine comprise (i) operating the engine in a scavenging mode such that opening of intake and exhaust valves of cylinders of the engine overlap and (ii) while transitioning the engine in/out of the scavenging mode: determining an engine torque request, creating a torque reserve by setting independent targets for throttle inlet pressure (TIP) and intake manifold absolute pressure (MAP), determining a target TIP based on a target total air charge, engine speed, and a previously-determined target engine volumetric efficiency (VE), controlling a wastegate valve based on the target TIP, determining a target MAP based on the engine torque request, and controlling a throttle valve based on the target MAP. During steady-state scavenging operation, the controller calculates a conventional target TIP based on the engine torque request and controls the wastegate valve based on the conventionally calculated target TIP.

  • Patent number: 10393032
    Abstract: An internal combustion engine includes a cylinder block that defines a cylinder and a cylinder head mounted to the cylinder block. A reciprocating piston is arranged inside the cylinder for compressing an air and fuel mixture at a geometric compression ratio of at least 10:1. A crankshaft is arranged in the cylinder block and rotated by the piston. An intake valve is operatively connected to the cylinder head and controls delivery of air to the cylinder for combustion therein. A mechanism provides a constant peak lift of the intake valve over an angle of rotation of the crankshaft that is at least 5 degrees, i.e., an extended dwell at peak lift. A multi-stage boosting system having first and second gas compressors is selectively controlled to pressurize air that is received from the ambient for delivery to the cylinder. A vehicle having such an engine is also disclosed.
