    Abstract: A system and method for operating an engine comprises an engine speed sensor generating an engine speed signal, a throttle position sensor generating a throttle position signal, a sensor module comprising at least one of a fuel pressure sensor generating a fuel pressure signal corresponding to a fuel pressure and a fuel temperature sensor generating a fuel temperature signal corresponding to a fuel temperature into the engine. A controller is coupled to the fuel injector, the engine speed sensor and the sensor module. The controller determines a pulse width duration for the fuel injector based on engine speed and throttle position, determining a pulse width correction factor as a function of at least one of the fuel temperature signal and the fuel pressure signal, determining a second pulse width duration based on the first pulse width, and operating the fuel injector with the second pulse width duration.

    Abstract: A snow vehicle is disclosed comprising a vehicle frame, a propulsion unit coupled to the frame, and a front ski steered by a steering mechanism. The snow vehicle has a chain coupling the sprocket of the propulsion unit and a chain tensioning device to take up the chain tension. The chain has a chain guide positioned below a lower run of the chain which directs the chain towards an upper run of the chain.
