ABSTRACT:
An air-cooled internal combustion engine equipped with a hydronamic retarder is combined with a cooling system for the hydronamic retarder fluid. The system comprises a cooling air shroud for directing cooling air past the engine in cooling relationship thereto and a cooling air fan for pushing air through the shroud. The system further includes a retarder oil cooler located upstream from the fan remote from the engine and circuit means are provided for circulating retarder oil through the cooler. Exhaust valves are provided in the shroud and are positioned for diverting at least a portion of the cooling air flow from the shroud when the valves are open. Thus, the overall pressure loss of the system may be decreased and the total flow of cool air through the cooler may correspondingly be increased to increase the cooling efficiency in the cooler.
