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
It’s not just the torque ...... it’s the speed that countsWhen it’s cold you need more than just torque, you need to be able to crank thatengine fast enough. New electronically managed engines need to reach a minimumspeed (typically around 100 RPM) before the electronic sensors will allowthe engine controller to release fuel into the cylinders.As soon as the starter has created enough torque to successfully turn the engineover it’s the speed that it can achieve that will determine if that engine isgoing to start.ProductTypeStarter Output@ 70 N . m * (kW)Engine Speed@ 70 N . m * (RPM)Titan TM 125In-line4.05.06.07.08.07.0406080201000Engine106RPMComp 1Offset4.05.06.07.08.05.0406080201000EngineRPM70Comp 2In-line4.05.06.07.08.06.0406080201000EngineRPM95Comp 3In-line4.05.06.07.08.06.0406080201000EngineRPM91Assumes (3)1000 CCA Battery* Torque required to crank typical big bore diesel engine @ 0 o FOf these gear reduced starters only the Titan125 can generate enough speedto successfully start this engine below 20 o F.
