Engine control system for marine propulsion

摘要

A marine propulsion system and particularly an outboard motor wherein the outboard motor is provided with a control for preventing engine damage in response to an abnormal condition by reducing the speed of the engine through disabling certain cylinders. The cylinders disabled are chosen on the vertical position of the cylinder in the engine so as to provide improved running and avoid undesirable results. In addition, the disabling of the cylinders is precluded until the abnormal condition has existed more than a predetermined time period upon initial start-up so as to permit unencumbered normal warm up of the engine.
