GM the jeep is warm blooded until the OD ambient and the temp of the engine, fuel, and other metal parts are the same. The wind chill will cool it down much faster then no wind. Question is, would there be any warmth left in no wind chill vs wind chill? Also, does the intake of the engine sense the wind chill?
Good point, but he didn't mention an engine compartment that was recently warm when he went out to crank it at -5*
Yes, windy conditions allow quicker cool-down than statically still ambients, even moreso if the wind is blowing directly into and thru the radiator, pushing the heat down and out under the vehicle - but the object being cooled down must be warmer than ambient temperatures to radiate that heat into still or windy condition
Which is why wind-chill affected him, not the KJ
Intake air is only at ambient temperature, not to sensed wind-chill because the blowing wind is at ambient temperature
Outdoor thermometer does not indicate wind-chill
Wind-chill at 10mph is not the same as wind-chill at 50mph
Point being: The wind chill affected him, not the already -5* engine and fuel - nor would it have further effected the fuel turning to slush in the fuel lines at that temperature - 'n'est ci pa? Also that Airtex, E8251 lift pump is only 3-5psi -
but wind chill is what humans feel on moist skin. If you were to put a cloth sock on the outside air temperature sensor and wet it you would get wet bulb temperature on your inside air temperature readout. Wet bulb temperature is similar to wind chill temperature and tells you the wet bulb depression which can help determine relative humidity. The only time wet bulb and dry bulb temperature is the same is when there is no humidity. Since our engines are not wet or moist they can't feel wind chill.
