Abstract: An ammonia dosing system has a canister whose interior contains ammonia luminophores and a delivery apparatus for delivering ammonia from the canister interior into an exhaust after-treatment system to entrain with engine exhaust flowing toward an SCR catalyst for catalytic conversion of NOx in engine exhaust.

Abstract: A motor vehicle power take off system for a motor vehicle engine includes a viscous coupling. The input rotor of the viscous coupling is provided with a variable geometry impeller section which allows direct control over the proportion of input torque on the input shaft transferred to the viscous fluid and thereby to an output shaft. Both passive and active control schemes are proposed.

Abstract: A power or motive source for an extensible fairing for an articulated motor vehicle is based on a fluid power system. The fluid power system is disposed on the vehicle to be exposed to airflow around the vehicle resulting from forward movement of the vehicle. A coupling mechanism responsive to exposure of the fluid power system to airflow for extending and retracting the extensible fairing responsive to changes in vehicle speed.

Abstract: Cooperative operation of an auxiliary power unit having a mechanical power output shaft with a transmission coupled power takeoff operation system of a vehicle is provided by allowing the vehicle's main engine to be cranked by the auxiliary power unit through the power takeoff operation system.

Abstract: A vehicle reporting its position, typically derived from a global positioning or other navigation system, implements idle time limitation protocols based on its position. The particular protocol can be derived from a central, updated location using a telematics link.

Abstract: An ABS tone ring is made of a thermo-set plastic material transparent to electro-magnetic radiation. A plurality of discrete, spaced magnets or ferro-magnetic buttons is arrayed in a circle, embedded in the tone ring. The thermo-set plastic is heat tolerant and resistant to road salt and oxidation and protects the magnets or buttons from oxidation and corrosion.

Abstract: An exhaust system for a motor vehicle engine includes mixing vent flaps in the exhaust pipe which open responsive to exhaust temperature. The vent flap forms a portion of the exhaust pipe when closed and is pivotally attached along one edge to the exhaust pipe to open inwardly into the exhaust pipe to constrict and accelerate flow in the pipe to allow outside air to be drawn into the exhaust pipe. A magnetic catch latches the vent flap in its closed position and a magnetic release responsive to increased temperature of the exhaust stream releases the vent flap.

Abstract: A vehicle having one or more small vehicle-mounted electricity generating wind turbines located within an area of wind recirculation. The electricity generated is used to recharge vehicle batteries, partially power an auxiliary electric propulsion motor, or supply vehicle parasitic loads.

Abstract: A combustion engine comprising an exhaust system containing a particulate filter (10, 52) for trapping particulate matter in engine exhaust passing through the exhaust system. A particulate trapping medium (18) inside a casing is selectively operable to a relatively lesser porosity for trapping particulate matter in the exhaust and to a relatively greater porosity for facilitating removal of trapped particulate matter during cleaning.

Abstract: A system (10) and method for removing heat from an engine compartment in a motor vehicle where heat generated by operation of a heat engine (12) that propels the vehicle tends to collect. Engine heat is collected in a thermofluid in a reservoir forming an evaporator (14) where the thermofluid absorbs heat sufficient to evaporate it. The vapor naturally migrates to a condenser (22) that is cooled sufficiently to condense the vapor back to liquid phase. The liquid falls by gravity back to the condenser.

Abstract: A system for deploying a barrier deterring approach by pedestrians to the exhaust outlet from a vehicle operates in response to exhaust temperature and stopping of the vehicle.

Abstract: A passive louver system providing supplemental and localized cooling for an engine compartment is implemented using magnetic catches for opening and closing of the louvers.

Abstract: A crossing arm for a vehicle having a longitudinal axis includes a body pivotably mounted onto the vehicle and configured for extension from a surface of the vehicle. The body has a free-standing, upwardly vertical position generally perpendicular to the longitudinal axis, and a horizontal position generally cantilevered from the vehicle and parallel to the longitudinal axis. An actuator is configured for pivoting the body from a vertical position to a horizontal position.

Abstract: A proactive cooling system and method improve the cooling of a motor vehicle apparatus, such as an engine or transmission, in a motor vehicle. The proactive cooling system boosts the primary cooling system connected to the motor vehicle apparatus by using an electronic controller, an information collecting module for collecting information related to the operation of the motor vehicle and an auxiliary cooling system. The auxiliary cooling system uses a power supply and a secondary cooling system in fluid communication with the primary cooling system. The power supply turns on the secondary cooling system by activating an activator and a secondary pump. The activator opens a bypass circuit to divert coolant from the primary cooling system into the secondary cooling system where the diverted coolant is cooled in a secondary heat exchanger. A secondary pump circulates the coolant through the bypass circuit and back to the primary cooling system.
