A roof-rack assembly for a vehicle includes a roof having a first support member extending along a length thereof. A second support member is spaced apart from the first support member and extends along a length of the roof. At least one cross-member extends between and is attached to the first support member and the second support member and is movable between a use position and a stowed position relative to the roof. The at least one cross-member extends away from a surface of the roof in the use position and is received generally within the roof in the stowed position.

A gas compression spring is mounted with an exterior element configured to allow a user to adjust the extension of the spring by rotating or sliding the exterior element. The user can line up an internal mechanism which is configured to limit the extension of the gas spring, and therefore stop the extension of the gas spring at a predetermined height. Additionally, an override mechanism is included where a user requires full extension of the gas spring. For example, the user can override the internal mechanism by applying a force in the direction of the extension, which disengages the mechanism allowing full extension. When the spring is compressed again, the mechanism resets and opens to the predetermined height. The gas spring can be utilized in a vehicle liftgate system, allowing the liftgate to open at one or more heights based upon the internal mechanism settings of the gas spring.

A control method for coupling a first engine to a second engine in a vehicle includes determining a current position of a throttle body that regulates power output from the first and second engines. Determining a set speed for the first and second engines that corresponds to a desired power output from the first and second engines. Determining a compensation position for the throttle body and moving the throttle body to the compensation position. Actuating a clutch to a closed position such that the first engine is coupled to the second engine. Determining whether the first engine and the second engine are in phase. Actuating the clutch to slip if the first engine is not in phase with the second engine and actuating the clutch to the closed position when the first engine and the second engine are in phase.

A frame for a gaseous fueled vehicle is provided. The frame includes a floor pan, a tunnel positioned centrally and longitudinally in the floor pan extending a full length of the frame, and a tank integrated into the tunnel, where the tank is circular in cross-section and has a variable diameter. The tunnel may also integrate two or more tanks.

An exhaust system for a dual crankshaft engine system having a first engine and a second engine having a common exhaust member open at an end thereof for venting engine exhaust. A first exhaust member is adapted to be coupled to the first engine and coupled to the common exhaust member. The first exhaust member has a first catalytic converter formed thereon. A second exhaust member is adapted to be coupled to the first engine and coupled to the common exhaust member and has a second catalytic converter formed thereon. A third exhaust member is adapted to be coupled to the second engine and coupled to the common exhaust member. A fourth exhaust member is adapted to be coupled to the second exhaust engine and coupled to the common exhaust member. A third catalytic converter is provided in the exhaust member.

A dual engine crankshaft coupling arrangement is provided. The coupling arrangement includes a starter clutch portion for frictionally engaging a crankshaft of a primary engine with a crankshaft of a secondary engine for starting the second engine. A phase clutch is also provided for engaging the first and second crankshafts in an angular specific relative orientation for proper timing relationships coupling of the engine crankshafts.

A space efficient, structurally rigid, integrated muffler and bumper assembly is provided. The muffler and bumper assembly comprises an extruded skeleton, an energy absorbing bumper, and a bumper fascia. The extruded skeleton is formed such that internal cavities or passage flow chambers exist. In turn, the walls of the flow chambers maintain a plurality of holes, allowing for passage of exhaust gases between chambers. The extruded skeleton also has an inlet and outlet for exhaust gas flow. Arms having tabs on the ends thereof extend from the top and bottom of the extruded skeleton such that the energy absorbing bumper, which maintains recesses in the top and bottom portions, snap-fits with the extruded skeleton. The extruded skeleton/bumper assembly is welded or otherwise mechanically fastened to the vehicle frame rails. The bumper fascia is introduced over the extruded skeleton/bumper assembly generally masking the assembly with the overall vehicle design. Both the energy absorbing bumper and the bumper fascia have bores formed therein to receive the exhaust outlet of the extruded skeleton.
