An internal combustion engine operating method and system include provisions for on-site fuel separation, accumulation of the resultant fractions, and an automatic control of engine fuel feed composition and air-to-fuel ratio in response to factors including engine operating temperature, engine load, liquid fuel temperature and ambient conditions. These systems and methods allow dramatic improvement in engine operating performance, hydrocarbon emissions levels, full range fuel characteristics compatible with a given engine and flexibility of operation under varying conditions of load and ambient temperature.

The method of operating an internal combustion engine employing a vaporizable liquid full range fuel mixture of constituents having different boiling points including the steps of separating at least a portion of said fuel into at least two fractions including a higher boiling fraction and a lower boiling fraction and operating said engine at least in part on said lighter boiling fraction at least when the operating temperature or said engine is below a predetermined minimum, and further operating said engine at least in part on said heavy fraction accumulated during at least a portion of the time said engine operates, said heavy fraction being supplied to said engine through a liquid fuel pump when the temperature in said liquid fuel pump exceeds a predetermined maximum.
