Method and device for controlling fuel injection in internal combustion engine

摘要

An improved method and system for the control of an engine fuel injection system. The control senses the speed variations either during a portion of a complete cycle and a complete cycle and/or from cycle to cycle in order to determine the load on the engine from preprogrammed maps based upon the engine characteristics. From this load and the speed reading, it is possible to obtain the desired engine fuel injection control. This not only reduces the costs of the system by reducing the number of sensors, but also permits adjustments to be made more rapidly. <IMAGE>
