A snowmobile is provided that includes a frame, an engine, an endless belt drive system, and an air intake system for the engine. The frame has a forward portion and an aft portion. The engine is mounted to the forward portion and the belt drive system is mounted to the aft portion and is operatively connected to the engine. The engine is a turbocharged four-stroke type engine.

Embodiments for controlling condensate in a charge air cooler are provided. In one example, a method for a charge air cooler comprises, responsive to a condensate level in the charge air cooler, increasing boost pressure and maintaining a requested level of torque by routing a portion of air flow exiting the charge air cooler to an intake passage upstream of a compressor. In this way, accumulated condensate in the charge air cooler may be removed while maintaining driver-requested torque.

The invention discloses a forced finned straight pipe condensation heat-supply heat exchanger, which comprises a shell, a combustor and a plurality of finned straight pipes, wherein the combustor is positioned on the upper part of the shell; the periphery of the combustor is provided with a group of finned straight pipe bundles consisting of a plurality of finned straight pipes which are tightly and uniformly distributed along the circumference; a smoke exhaust pipeline which consists of the shell and a plurality of tightly arranged finned straight pipes is arranged below the combustor; the smoke exhaust pipeline is emptied through a smoke outlet; two ends of the finned straight pipes are respectively front water main pipes and rear water main pipes; clapboards are arranged in the rear water main pipes; the rear water main pipes are separated into a water inlet area and a water outlet area through the clapboards; and water flow enters part of the finned straight pipes through the water inlet area, reaches the front water main pipes and enters the water outlet area of the rear water main pipes through the other part of the finned straight pipes. The inwards folded finned straight pipes serve as basic elements of the forced finned straight pipe condensation heat-supply heat exchanger, and the heat exchange efficiency is obviously improved.

Cooking apparatus comprises an oven. The oven comprises a cooking chamber, a heated air source and two or more vents through which, in use, heated air can vent from the cooking chamber. The two or more vents comprise at least one lower vent and at least one upper vent. The at least one lower vent is provided at a lower height than the at least one upper vent. The at least one upper vent is controllable to regulate a flow of heated air therethrough.
