A snowmobile four-cycle engine arrangement, includes: a four-cycle engine arranged in an engine compartment formed in the front body of a snowmobile with its crankshaft laid substantially parallel to the body width and having a cylinder case inclined forwards with respect to the vehicle’s direction of travel. The packaging can be conformed into a service configuration in which the flap uncovers the opening and a first storage configuration in which the flap closes the opening. In some embodiments, an N-of-M coding strategy is employed, where, for any given time frame, only N of the M channels are selected and illuminated to stimulate the auditory nerves. These wireless access points, applied to the home or office environment, provide wireless networks without the overhead of building a physical, wired network between all networked devices.
