An off-road vehicle includes a vehicle body frame, a cabin, an engine room, an internal combustion engine, and an engine room cover. The engine room is provided behind the cabin. The engine is provided in the engine room and supported by the frame. The intercooler includes an intercooler core and is provided along an intake conduit extending toward the engine and provided above the engine. The engine room cover includes an upper surface exposed to outside the vehicle, is provided above the engine, and defines an upper boundary of the engine room. The engine room cover is provided above the intercooler and includes a window opening through which the intercooler core is exposed to outside the vehicle. The window opening includes a circumferential edge portion that faces an upper surface of the intercooler from above. The window opening is provided along an outer circumferential edge of the intercooler core.

Systems, devices, and methods are disclosed for attaching two automotive components comprising different materials having different coefficients of expansion, comprising providing a flange around a perimeter of each of the components, wherein at least one component defines a plenum contiguous to the perimeter, providing corresponding inner faces of the flanges, providing a channel in at least one of the corresponding faces of the flanges, wherein the channel is coaxial to the perimeter, disposing a gasket in the channel, and surrounding the flanges with a locking ring, wherein the ring has an axial channel and a pin disposed perpendicular to the channel to secure a first end of the locking ring to a mating second end of the locking ring.

An engine system includes a charge air cooler assembly that is configured to direct air to different parts of the engine system and to reduce overall void volume within the air intake system. The charge air cooler assembly includes a first stage air-to-air cooler arranged to direct a first charge air along a first direction from an inlet to an outlet of the first stage air-to-air cooler. The charge air cooler assembly also includes a second stage air-to-air cooler arranged to direct a second charge air along a second direction from an inlet to an outlet of the second stage air-to-air cooler that is different from the first direction. In some embodiments, the first stage air-to-air cooler and the second stage air-to-air cooler are each disposed in a parallel flow arrangement relative to an air driver of the engine system.

An electrically assisted exhaust gas turbocharger has a fresh air-conducting section, an exhaust gas-conducting section and a bearing section. A rotating assembly includes a shaft and a compressor wheel connected to the shaft. A turbine wheel is connected to the shaft for conjoint rotation. The compressor wheel is rotatably accommodated in the fresh air-conducting section and the turbine wheel is rotatably accommodated in the exhaust gas-conducting section. The shaft is rotatably mounted in the bearing section and has an electric motor with a rotor and a stator. The rotor is arranged in operative connection with the shaft. A coolant channel in the electrically assisted exhaust gas turbocharger is designed for coolant to flow therethrough. The coolant is compressed air downstream of the compressor wheel and can be fed to the compressor wheel downstream and/or upstream thereof. A sealing element is formed between the electric motor and the fresh air-conducting section.
