Abstract: A vehicle includes a plurality of ground-engaging members, a frame assembly supported by the ground-engaging members, and a powertrain assembly supported by the frame. The powertrain assembly includes at least an engine. The vehicle further includes a cooling assembly fluidly coupled to at least the engine and which includes a radiator and at least one fan positioned rearward of the radiator and angled relative to the radiator. A rear shroud is positioned between the radiator and fan and includes an air bypass assembly to exhaust air thought he rear shroud at higher speeds of the vehicle.

Abstract: An exhaust after-treatment system for an internal combustion engine is provided having an exhaust passage in fluid communication with the exhaust manifold of the engine. A turbocharger coupled to the exhaust passage is operatively driven by a first portion of exhaust gases exiting the exhaust manifold. A bypass line is disposed parallel to the turbocharger, and fluidly coupled to the exhaust passage upstream and downstream of the turbocharger. The bypass line receives a second portion of the exhaust gases exiting the exhaust manifold. A fuel injector disposed in the bypass line injects a pre-determined amount of fuel in the bypass line to the second portion of the exhaust gases. An exhaust after-treatment module located downstream of the turbocharger and the bypass line receives the mixture of the first portion and the second portion of the exhaust gas.
