Fuel injection control system for outboard motor

摘要

A control system for a multicylinder direct injection engine determines a control variable for each cylinder based on engine speed and engine load. The control variable can be altered depending upon an operating temperature of each cylinder independently of the others. The operating temperature of each cylinder is monitored through a temperature sensor disposed on the fuel injector nozzle. The cylinders having nozzles operating at a temperature lower than a normal temperature or normal range of temperatures can have the control variable altered to increase the power of that cylinder and the temperature of that cylinder. The cylinders having nozzles operating at a temperature higher than a normal temperature or normal range of temperatures can have the control variable altered to lower the operating temperature of the nozzle.
