Abstract
A separate lubricating system for an engine including a lubricant reservoir and a system for delivering lubricant from the reservoir to the engine for its lubrication. A sensing device is provided in the lubricant system for sensing the lubricant flow and comparing it with a desired flow for providing a warning signal in the event of inadequate lubricant flow. The invention is illustrated in a specific embodiment as applied to an outboard motor.
Claims28
A non-return lubricating system for a two-cycle internal combustion engine, a lubricant system for delivering lubricant from said reservoir to said engine for its lubrication and consumption therein without return to said lubricant reservoir, means for measuring the amount of lubricant flowing through said system, and means for providing a signal in the event the amount of lubricant flow measured is less than a predetermined amount.
In a lubricating system for an internal combustion engine having a lubricant reservoir, a lubricant system for delivering lubricant from said reservoir to said engine for its lubrication, a pump for delivering lubricant to the engine, said means for measuring the amount of lubricant flowing through said system, said means for sensing the amount of lubricant flowing through the system comprising an impeller sensing the amount of lubricant flow from said lubricant reservoir to said pump, and means for providing a signal in the event the amount of lubricant flow measured is less than a predetermined amount.
In a lubricating system for an internal combustion engine having a lubricant reservoir, a lubricant system for delivering lubricant from said reservoir to said engine for its lubrication, means for measuring the amount of lubricant flowing through said system, means for measuring the speed of said engine, and means for providing a signal in the event the amount of lubricant flow measured is less than a predetermined amount required for lubrication at the measured speed.
