The hard starting problems of diesel engines in below zero / freezing temperatures are generated by two factors. One is the initial cold air being drawn in to the turbocharger and compressed in the engine?s cylinder head. The second is the fuel itself, is also cold and also this sub zero / freezing temperature fuel is sprayed to the cold engine?s combustion chamber, where it mixes while using cold air drawn thru turbocharger.
