Title:
METHOD AND DEVICE FOR CONTROLLING SURFACE TEMPERATURES ON INTERNAL COMBUSTION ENGINES
Document Type and Number:
WIPO Patent Application WO/2011/008608
Kind Code:
A3
Abstract:
A device for controlling surface temperatures on exposed surfaces of internal combustion engines to maintain all exposed engine surfaces below a predetermined maximum temperature includes a cooled enclosure enclosing components of the engine that normally have surfaces reaching temperatures above the predetermined maximum during normal operation of the engine. The cooled enclosure is sized to provide an air space between the enclosed engine surfaces and the exposed walls of the enclosure to slow heat transfer from the enclosed engine surfaces to the exposed enclosure walls, and the exposed enclosure walls are cooled, such as by circulation of cooling fluid through fluid circulation spaces within the walls, to maintain the exposed walls below the predetermined maximum. Cooling fluid for the cooled walls can come from the usual engine cooling system.
