A stackable track assembly and method for stacking a booster and/or track frame is disclosed. The stackable track assembly includes a base, a track portion disposed in the base, and a frame extending out of the base and laterally across the top of the base. The stackable track assembly further includes a tab and slot for laterally coupling two track assemblies. The stackable track assembly further includes a receiving member and engagement member for vertically and/or laterally coupling two track assemblies. In some implementations, the track assembly may include a booster for accelerating a toy vehicle.

This utility model discloses a building block and track building block toy including four of single components and eight of magnetic spheres; each one of single components comprises a first connecting rod, a second connecting rod and a third connecting rod; the first connecting rod, the second connecting rod, and the third connecting rod are sequentially connected to form a “” shape; a first insertion portion is disposed on an end of the first connecting rod, and another one of first insertion portion is disposed on an end of the third connecting rod; second insertion portions extend vertically at both ends of the second connecting rod; each of the second insertion portions is provided with one of inserting holes. A plurality of the building blocks are able to be adsorbed together by magnetic spheres and assembled into various shapes.

An exhaust system for a combustion engine vehicle includes an exhaust pipe extending between an exhaust inlet disposed opposite an exhaust outlet. The exhaust inlet and exhaust outlet are in fluidic communication with one another. The exhaust inlet is configured to receive an exhaust gas produced by an internal combustion engine of the combustion engine vehicle. A second pipe has an air inlet extending from and connected to the exhaust pipe. The second pipe is configured to be in fluidic communication with the exhaust outlet. The air inlet is configured to receive an outside flow of air. The exhaust gas from the combustion engine vehicle and the outside flow of air captured by the air inlet when the combustion engine vehicle is moving forward are configured to be combined and to cooperatively exit out the exhaust outlet.

A vehicle configured to move through a network of interconnected tubes includes a body, a motor, a motorized wheel, a biasing assembly, and a first element. The motorized wheel directly engages an inner surface of the tubes. The biasing assembly causes the motorized wheel to maintain continuous contact with the inner surface of the tubes during operation. A waist of the vehicle is constrained by an inner diameter (D) of the curved tube, a radius of curvature (R) of the curved tube, and a length (L) of the wheelbase of the vehicle. The waist of the body is sized such that the vehicle can freely move within any of the tubes without getting stuck therein.
