1.6.4 Temperature Compensation
The task of computing fuel consumption for a diesel engine is further complicated by the
following two factors:
1) Diesel fuel expands when heated
2) Diesel fuel is heated as it passes through the engine
When using volumetric sensors such as positive displacement sensors or turbine flow sensors,
simply subtracting the return flow rate from the supply flow rate without taking these factors
