ABSTRACT:
A number of embodiments of internal combustion engines incorporating toothed belt driven overhead camshafts. In each embodiment, the driving belt is contained within a protective case that is separated from the engine by an air gap for insulation and a cooling fan driven by the camshaft circulates cooling air through the belt case. All embodiments employ air inlets for the belt case that are disposed in sheltered areas so as to prevent contaminants from being drawn into the belt case. In addition, a generator is contained within the belt case for protection.
