Air Cooling Systems for Snowmobiles

原文（中国語）

An air cooling system for a snowmobile having a forward frame assembly defining an engine bay, an engine positioned in the engine bay and a turbocharger positioned outboard of the engine bay. The air cooling system includes an intercooler in downstream fluid communication with the turbocharger. The intercooler is configured to cool compressed air from the turbocharger. An air channel is positioned forward of the intercooler. The air channel has a lower wall and a pair of oppositely disposed side walls that direct ambient ram air into the intercooler such that heat transfers from the compressed air to the ambient ram air in the intercooler, thereby cooling the compressed air and increasing the density of the compressed air before the compressed air enters the engine.
