ABSTRACT:
The invention includes a method of reducing drag in a pipeline and/or improving the combustion efficiency of a fuel burning device by adding a grafted polymer to a hydrocarbon product. The invention also includes a method of improving the combustion efficiency of a gasoline engine by adding a grafted polymer to fuel and combusting the fuel within the gasoline engine, the grafted polymer having a viscoelastic effect in gasoline in the gasoline engine to generally correspond to a duration of the intake stroke/compression stroke/fuel burn sequence in a gasoline engine.
