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. When tractors were first developed, they used enormous steam engines that were notoriously unreliable and hard to maintain. These were phased out around the turn with the twentieth century and substituted for internal combustion engines which were smaller though powerful and ran on a number of fuels including kerosene, ethanol and gasoline. By the 1960s several of these engines were phased out and only more effective internal combustion engines that ran on diesel and after this, biodiesel. Before starting battle a soldier must prepare.
