  • Patent number: 9909482
    Abstract: A system and method for evaluating the efficiency of an oxidation catalyst of a vehicle exhaust system includes a diagnostic control system including a controller operatively connected to the exhaust system and at least one temperature sensor disposed proximate the oxidation catalyst to measure the temperature of the exhaust gas. The controller determines an operating state of at least one of the engine and exhaust system and initiates a particulate filter regeneration process in response to the detected operating state. The controller defines a first diagnostic index value and calculates a second diagnostic index value based upon the first diagnostic index value and an offset value. An oxidation catalyst efficiency validation module determines the efficiency of the oxidation catalyst.

  • Publication number: 20180058343
    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.

  • Patent number: 9902438
    Abstract: A system is configured to control aerodynamics of a vehicle. The vehicle includes a vehicle body arranged along a longitudinal axis with a first vehicle body end configured to face incident ambient airflow. The system includes an aerodynamic-aid element mounted to the vehicle body and configured to generate a downforce thereon via controlling the incident ambient airflow. The system also includes an adjustable flap arranged at the aerodynamic-aid element. The adjustable flap is configured to shift relative to the aerodynamic-aid element and thereby control movement of the incident ambient airflow relative to the aerodynamic-aid element. The system additionally includes a mechanism configured to vary position of the adjustable flap relative to the aerodynamic-aid element and thereby vary a magnitude of downforce generated by the aerodynamic-aid element.

  • Patent number: 9902439
    Abstract: The vehicle has a vehicle body including a first body end facing incident ambient airflow, a second body end opposite of the first body end, an underbody section spanning a distance between the first and second body ends, and vehicle subsystem arranged proximate the underbody section. A panel is moveably mounted to the underbody section and configured to regulate access of an underbody portion of the incident airflow to the subsystem. A mechanism is configured to shift the panel to selectively expose at least a part of the subsystem to the underbody portion of the incident airflow and shield the subsystem to thereby enhance aerodynamics of the vehicle body. A sensor detects a vehicle operating parameter and communicates the detected operating parameter to a controller. The controller is configured to regulate the mechanism and thereby shift the panel in response to the detected vehicle operating parameter.
