Abstract
A method and composition for improving the mechanical efficiency of a engine is provided. Ultra-high molecular weight polyisobutylene (PIB) added to the fuel changes the momentary mechanical properties of the fuel during induction. The additive provides a more uniform spray droplet size, increases the extensional viscosity of the fuel, and adapts other physical properties, under induction conditions.
