Description / Abstract:
Note: Nothing in this standard supercedes
applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence.
Purpose. To determine if the total coolant
flow, flow to the radiator, flow to the heater, flow balance in
V-engines, and flow in any other branch of a cooling circuit, meets
the design intent under various thermostat opening conditions. To
provide hydraulic restriction (pressure drop vs. flow
characteristics) data for cooling system modeling and to provide
model validation. To ensure surge tank function under dynamic
conditions, such as maximum engine speed. To determine the
necessity for a second degassing line.
Foreword. This is a bench coolant flow test
procedure used for coolant system development.
Applicability. All liquid cooled engines.
