Abstract: Methods and systems are provided for a hydrocarbon (HC) trap system in an engine air induction system. In one example, a system may include a pillow-case type HC trap housed in a rectangular opening formed in a wall of an air conduit at the outlet of an air cleaner box. A frame may be integrally formed around the opening to support the HC trap protruding outward from the wall.

Abstract: A vehicular sweeping machine that is adapted to rotate a broom about a substantially horizontal axis to sweep material into a broom conveyor of fixed width is provided with a modular broom assembly that can accommodate a broom of a first length and a broom of a second length that is longer than the first length. The modular broom assembly includes a primary broom enclosure that is adapted to accommodate the broom of the first length, and an extension assembly that includes broom extension components which are adapted to be installed on the primary broom enclosure to increase the width of the primary broom enclosure to accommodate the broom of the second length, and to direct material swept by the broom of the second length into the broom conveyor.

Abstract: Systems are provided for electromagnetic actuation of a valve mechanism. A valve is linearly moveable between a first closed position and a second open position. A first spring is compressed when the valve is in the first closed position, and a second valve spring is compressed when the valve is in the second open position. An electromagnetic actuation assembly and a permanent magnet is combined with the valve, such that the valve is latchable in either a closed or open position, and is readily movable between positions through application of energy to the electromagnetic circuitry. The electromagnetic circuitry is controllable to increase or decrease the local magnetic flux, such as to promote movement of the valve, or to provide a soft landing of the valve at either end of movement. Some system embodiments provide energy recovery, feed back, and/or feed forward sensing and control.
