It is also contemplated that the hood 114 could be fixed, in which case a storage bin 118 would not be provided.
  • the front cowling assembly 100 defines an internal volume inside which portions of an engine cooling system 200, portions of an air intake system 300, and, as mentioned above, the storage bin 118 are disposed. Other components of the vehicle 10 are disposed at least in part inside the internal volume defined by the front cowling assembly 100, such as a steering column and electronic control system, but these will not be described herein.

[0056] Additional details of the front cowling assembly 100 will be discussed further below when discussing the engine cooling system 200 and the air intake system 300.
  • the engine 32 is liquid-cooled. As such, liquid coolant flows through passages formed in the engine 32 to absorb heat from the engine 32, thereby cooling the engine 32. From the engine 32, the hot coolant flows in a hose 202.

  • the coolant then flows upwardly through conduits in the radiators 206, 208. Air flowing through the radiators 206, 208 absorbs heat from the coolant, thereby cooling the coolant. Additional details regarding the flow of air through the radiators 206, 208 will be provided below.
  • the cooled coolant then flows from the top of the radiators 206, 208 into a hose 210. The two flows of coolant then merge into a hose 212 connected to the hose 210. The cooled coolant then flows through the hose 212 and is returned to the engine 32 to cool the engine 32.
  • One or more pumps (not shown) cause the coolant to flow through the above-described circuit. The pumps can be electrical or mechanically driven by the engine 32.
  • a coolant tank 214 is provided behind the storage bin 118 on a right side of the longitudinal centerline 130 of the vehicle 10.
  • the coolant tank 214 can be filled with coolant by removing a cap 216 of the coolant tank 214.

  • a hose 218 connects the coolant tank 214 to the engine 32 such that the coolant tank 214 can supply coolant to the engine 32 should there be an insufficient amount of coolant flowing through the engine 32.
  • a hose 220 connects the engine 32 to the coolant tank 214 such that air/gas in the coolant circuit can flow out of the engine 32 to prevent the formation of hot spots in the engine 32.
  • any overflow of coolant in the engine 32 is also returned to the coolant tank 214 by the hose 220.
  • a hose 222 is connected to the coolant tank 214, extends downwardly therefrom, and opens to the atmosphere to prevent the air/gas being returned to the coolant tank 214 from pressurizing the coolant tank 214 and to permit leakage of coolant out of the coolant tank 214 when the level of coolant inside the coolant tank 214 reaches a predetermined level.
  • the left and right radiators 206, 208 are disposed inside the front cowling assembly 100 at the rear of the lower cowling 104. As can be seen in Figs.
  • the left and right radiators 206, 208 are disposed on the left side and right side respectively of the longitudinal centerline 130.
  • the lower cowling 104 defines left and right air inlets 132, 134 on opposite sides of the longitudinal centerline 130 forwardly of the radiators 206, 208.
  • Lines normal to the planes defined by the air inlets 132, 134 are angled relative to the longitudinal centerline 130, but have a forwardly extending component, as such the air inlets 132, 134 face generally toward the front of the vehicle 10.
  • the air inlets 132, 134 face generally toward the front of the vehicle 10 such that when the vehicle 10 moves forward, air flowing parallel to the longitudinal centerline 130 relative to the vehicle 10 enters the air inlets 132, 134.
  • a duct 136 extends between the left air inlet 132 and the left radiator 206 such that air entering the left air inlet 132 flows through the duct 136 and then through the radiator 206.
  • a duct 138 extends between the right air inlet 134 and the right radiator 208 such that air entering the right air inlet 134 flows through the duct 138 and then through the radiator 208.

  • the main components of the air intake system 300 are an air duct 302, an air box 304, an air box 306, a throttle body (not shown) and an air intake manifold (not shown). It is contemplated that the air intake system 300 could have only one air box.
  • the air duct 302 is disposed on the left side of the longitudinal centerline 130 under the left upper cowling 106. As can be seen in Fig. 6, the left side of the air duct 302 generally follows a shape on an inner wall of the left side of the front cowling assembly 100. An air duct inlet 308 of the air duct 302 is disposed in proximity to a front of the left upper cowling 106. As can be seen in Fig.
  • the air duct inlet 308 faces generally toward the left side wall 124 of the storage bin 118.
  • the air duct 302 has an integrally formed wall 310 disposed forwardly of the air duct inlet 308 and facing generally toward the front of the front cowling assembly 100. It is contemplated that the wall 310 could be a separate part fastened to the air duct 302. The wall 310 will be discussed in greater detail below.
  • the air duct 302 extends upwardly and rearwardly over the radiator 206 to an air duct outlet 312.

  • the hose 320 is connected to the throttle body (not shown) which controls the air flow to the engine 32.
  • the throttle body is connected to the air intake manifold (not shown).
  • the air intake manifold is connected to the engine 32 to supply air to each of the cylinders (not shown) of the engine 32.
  • a hose 322 fluidly communicates the crankcase (not shown) of the engine 32 with the hose 320 to return blow-by gases (i.e. combustion gases that flow from the combustion chambers to the crankcase) to the air intake system 300.
  • the left intake trim 110 defines an air inlet 144 on a left side of the longitudinal centerline 130. As best seen in Fig.
  • the air inlet 144 is disposed vertically above the air inlet 132 and vertically below the left headlight 102. As can also be seen in Fig. 5, the air inlet 144 is disposed laterally between the inner and outer edges of the air inlet 132 and has a surface area that is smaller than the surface area of the air inlet 132. A line normal to the plane defined by the air inlet 144 (not shown) is angled away from the longitudinal centerline 130, but has a forwardly extending component, as such, the air inlet 134 faces generally toward the front of the vehicle 10.
  • the air inlet 144 faces generally toward the front of the vehicle 10 such that when the vehicle 10 moves forward, air flowing parallel to the longitudinal centerline 130 relative to the vehicle 10 enters the air inlet 144. It is contemplated that the left intake trim 110 could be omitted, in which case the air inlet 144 would be defined by one or both of the upper and lower cowlings 106, 104.
  • the wall 310 is disposed rearwardly of the air inlet 144 and is generally aligned therewith.
  • the wall 310 also has a greater surface area than the air inlet 144.
  • the wall 310 thus prevents water, dust and debris entrained with the air flowing in the inlet 144 from entering directly into the air duct inlet 308 and as a result reduces the likelihood of such water, dust, and debris from entering the air intake system 300.
  • the wall 310 has channels 324 on the front surface thereof that help separate the water, dust and debris from the air when the air hits the wall 310.
  • the air duct inlet 308 has a forwardly projecting lip 326 around a portion of a periphery thereof to assist the wall 310 in deflecting the air entering via the air inlet 144 away from the air duct inlet 308.
  • Air entering the air inlet 144 flows inside the cowling assembly 100, is deflected by the wall 310 and then enters the air duct inlet 308. Due to the relative proximity between the air inlet 144 and the air duct inlet 308, the air being supplied to the air intake system is relatively cool. From the air duct inlet 308, the air flows sequentially through the air duct 302, the air box 304 where it is filtered by the air filter 316, the hose 318, the air box 306, the hose 320, the throttle body, the air intake manifold and is finally supplied to the engine 32.
  • the right intake trim 112 defines an air inlet 146 that is a mirror image of the air inlet 144. Air entering the air inlet 146 is supplied to the internal volume defined by the front cowling assembly 100 on a right side of the longitudinal centerline 130 to the right of the storage bin 118. The storage bin 118 thus prevents air entering the air inlet 146 from entering the air duct inlet 308 directly. It is contemplated that the air intake system 300 could be arranged as a mirror image of what is illustrated in the figures such that the air inlet 146 would be in proximity to the air duct inlet 308.
