Abstract: A fuel fired burner defines an axially extending flow path. An airless fuel nozzle sprays fuel droplets within the fuel fired burner in a direction generally along the axially extending flow path. An exhaust gas inlet directs exhaust gases from a vehicle exhaust system toward the airless nozzle in a direction that is transverse to the axially extending flow path. The exhaust gas mixes with the fuel droplets resulting in an exhaust gas/fuel mixture.

Abstract: A fuel-fired burner in a vehicle exhaust system is selectively activated to increase exhaust gas temperature to a desired reference temperature. The fuel-fired burner can be either a partial range burner or a full range burner. A control strategy activates the fuel-fired burner only when needed to provide NO2 based passive regeneration of a diesel particulate filter in a fuel efficient manner. The control strategy includes at least one of a look-up table which outputs the desired reference temperature as a function of engine operating conditions, a comparison of pressure characteristics to predetermined thresholds, and a steady-state model or a transient model that outputs the desired reference temperature as a function of exhaust back-pressure and estimated exhaust oxygen flowrate.

Abstract: A vehicle control system includes at least one driver input, a supervisor and at least one sub-system controlled by the supervisor. The supervisor assesses the driver input to establish actual driver demand and controls the sub-systems accordingly. As a result intuitive driver demand is identified and met.

Abstract: A vehicle control system includes at least one driver input [(20)], a supervisor [(14)] and at least one sub-system [(18)] controlled by the supervisor. The supervisor assesses the driver input to establish actual driver demand and controls the sub-systems [(18)] accordingly. As a result intuitive driver demand is identified and met.

Abstract: A vehicle hydraulic system (10) includes a pump (12), a low pressure line (16) and a high pressure line (30). A restriction and bypass system is provided on the low pressure system allowing charging up of an accumulator (50) on the high pressure system. Furthermore a torque sensor, D, E, F is provided on a clutch hub (96) of a multi-plate wet clutch.
