Outboard motor, the diagnosis support system of the outboard motor, and a recording medium storing a program for operating a computer as a diagnosis support system for an outboard motor

摘要

PROBLEM TO BE SOLVED: To provide an outboard engine capable of easily diagnosing the rigging and allowing easy diagnosis of the cause of an engine disorder, etc.;SOLUTION: The outboard engine is to be mounted on a hull where a fuel tank and a battery are installed, in which at each specified sampling period (for example, one min), the engine speed, fuel pressure, battery voltage, etc., are recorded as the latest operating condition data for a specified recording time (for example, 13 min). This is received as applicable by a diagnosis support system, and the part in which the engine speed goes approximately constant is taken up as the operating condition data when the operation is performed in steady condition. The rigging condition of the engine and hull concerning the fuel supply system is diagnosed from the relation between the engine revolving speed and fuel pressure contained in this operating condition data, while the rigging condition concerning the electric system is diagnosed from the relation between the engine revolving speed and battery voltage.;COPYRIGHT: (C)2002,JPO
