Abstract
Design practices and principles for motor truck engine cooling systems are discussed. Major topics covered are:
-
1.
How engine cooling is measured, including correlation of test results to ambient, outdoor and tunnel tests, amount of cooling required including standard versus optional increased cooling, importance of speedability on grade specific levels of cooling to be provided.
-
2.
Heat transfer performance considerations, including the radiator as a heat exchanger, heat transfer theory applied to the engine.
-
3.
Pressure cooling systems, including effect on air-to-boil and metal temperatures.
-
4.
Effect of installation parameters on cooling performance, including grille and fan, selecting radiator core size.
-
5.
Temperature control.
-
6.
Coolant circuit stability considerations, including typical circuits, design criteria and performance of Posi-Temp system for diesels.
-
7.
Radiator structure, including structural design factors, design criteria for tube-and-fin and heavy duty tube-and-center, sheet metal tank versus bolted tank design.
-
8.
Radiator mounts.
-
9.
Structural tests.
-
10.
Auxiliary cooling requirements.
