Why is that big bore dieselso hard to start in the cold?Cold temperatures inhibit the chemicalreaction within the batteries, reducingtheir efficiency. At 0 o F theavailable current from the batteries isonly about 45% of the output availableat 80 o F.To make matters worse, thickening ofthe fluids and tighter clearances dueto metal contraction make the engine3 1/2 times more difficult to turnover.Add these together and you get a dieselengine that is 4 to 5 times harderto turn at 0 o F than it is at 80 o F.350%250%Cranking PowerRequired165%100%o Fahrenheit80 o32 o0 o-20 oBattery PowerAvailable100%83%61%45%4xNighttime lows5x3x2x 1xWhen you have trucks goingcoast to coast and north to southyou know that you’re going to hitcold weather.You may have an engine that is4-5 times harder to turn over atnight than it was just that morning.Daytime HighsYou need a cranking motor thathas the right mix of power, torqueand speed to keep you on themove.The Power of Excellence
