Abstract: Embodiments described herein relate to internal combustion engine exhaust after-treatment systems and to methods of treating exhaust of an internal combustion engine.

Abstract: A rear axle/suspension module (18) is associated with a chassis frame (10) in a way that facilitates installation and removal to provide more efficient assembly plant operations with fewer parts and less floor space. Also provided is a method of re-equipping a truck that has one particular model of drive axle and suspension module with a different model.

Abstract: A protection structure is formed from a platform and a forward pair and a rearward pair of load bearing members, where each load bearing member is attached at a lower end to the platform. A first and second pair of side beams are attached to the outer side of one of each of the pair of load bearing members, respectively. A pair of upper corner beams are attached to an upper end of each of the load bearing members and attached to an end of each of a forward pair and a rearward pair of transverse members, where a beam is attached to the opposite end of each of the pair of transverse members. Body panels may be attached to the protection structure to define and enclose the occupant compartment.

Abstract: A school bus rollover protection structure is formed from a vehicle support platform and a forward pair and a rearward pair of vertically extending load bearing members where each vertically extending load bearing member is attached at a lower end to the vehicle support platform. A first and second pairs of longitudinally extending side beams are attached to the outer side of one of each of the pair of vertically extending load bearing members, respectively. A pair of upper corner longitudinally extending beams are attached to an upper end of each of the vertically extending load bearing members and attached to an end of each of a forward pair and a rearward pair of transverse load bearing members, where a center upper longitudinally extending beam is attached to the opposite end of each of the pair of transverse load bearing members. Non-structural body panels may be attached to the school bus rollover protection structure to define an occupant compartment.

Abstract: A passenger bus body is fabricated in a mold by introducing resin and reinforcing fibers into a cavity of the mold that causes the introduced material to seamlessly join lengthwise margins of the roof (18, 18A) with upper lengthwise margins of the side walls (14, 16; 14A, 16A) and to seamlessly join lengthwise margins of the floor (12, 12A) with the lower lengthwise margins of the side walls. Floor rails (32, 34) of structural composite can eliminate the need for a separate metal chassis frame.
