Abstract:

To make reasonably certain the efficient starting and operating of military construction equipment in extreme low temperature down to -65 deg F. This task was related to a project with the same purpose in high temperatures. To develop a cooling system for Internal combustion engines that will provide uniform heat and all temperatures throughout the engine and thereby result in more efficient engine operations under low temperature conditions. To present the results of testing, studying, and developing variations of boiling-condensing cooling systems which maintain constant engine temperatures as a result of boiling the coolant rather than by using thermostats, covers, and other controls. Cooling of internal combustion engines by allowing the coolant to boil and be condensed in a closed cycle is concluded to be a superior method, with many beneficial side effects other than constant temperature without mechanical control. Possible limitations of the system on particular types of engines are discussed at length, as well as a number of commercial, developed, and proposed variations of the basic application.
