Engineering · Diesel — Fuel
The pour point of a diesel fuel is important because it indicates the temperature:
- AAt which the fuel ignites
- BBelow which the fuel will no longer flow freely✓ Correct
- CAt which the fuel reaches injection viscosity
- DAt which the fuel boils
Explanation
Pour point is the lowest temperature at which a fuel will still flow. Below it the fuel waxes/gels and will not pump, so cold-climate operation requires heated lines or a lower-pour-point fuel.
