First Claim
Patent Images
1. A method for blending a diesel fuel composition while retaining or improving diesel engine performance comprising the steps of:
- providing a major amount of diesel fuel at a temperature of 32°
F. or less;
blending a minor amount of biodiesel at a temperature above 32°
F. with the diesel fuel; and
producing a resulting diesel fuel composition without shock crystallization.
