Apparatus and method for controlling engine response versus exhaust smoke

摘要

An engine control system is provided which calculates an optimum air/fuel ratio by minimizing the smoke produced by the engine while at the same time maximizing the engine response time for all altitudes over which the engine operates. The control system includes a microprocessor, an ambient pressure sensor, fuel injectors, and storage means. A manual adjustment is provided that allows an operator to manually adjust the air/fuel ratio within certain pre-defined limits of the optimum value.
