Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic refueling control device for an automatic refueling system of a separate refueling system.

Conventionally, the method of refueling two-stroke outboard engines used in small vessels such as taboos was to manually mix gasoline fuel oil and lubricating oil in an appropriate ratio (for example, 10:1). There is a method of using mixed oil. However, this method was very cumbersome to operate. Furthermore, there was a drawback that lubricating oil was wasted. In view of these drawbacks, separate oil supply systems have been proposed that supply lubricating oil and fuel oil separately. However, conventional systems of this type store all lubricating oil in one tank and This has the disadvantage that the amount of oil supplied to the engine becomes too large due to the large pressure of the lubricating oil in the tank, resulting in increased wasteful consumption.

The present invention was made in view of these drawbacks, and its purpose is to provide a system with a small-capacity auxiliary taxi that can supply an appropriate amount of oil to the engine and eliminate unnecessary consumption of lubricating oil. In addition to automatically supplying lubricating oil from the main tank to the auxiliary tank, if the lubricating oil in the auxiliary tank recedes due to trouble, the engine will automatically stop and an alarm will be issued. To provide an automatic lubrication control device for a separate lubrication system that can protect the oil supply system.

As described above, the present invention supplies lubricating oil to the knees from the auxiliary tank by applying lubricating oil to the main tank and the auxiliary tank, which has a small capacity relative to the main tank, so it does not work like the conventional separate lubrication system. It prevents overfilling due to the pressure of a large amount of lubricating oil and allows for proper lubricating, so there is no wasteful consumption of lubricating oil, and it does not require more trouble than when using mixed oil. In addition, there is a means for detecting the liquid level in the auxiliary tank using a level gauge and controlling the tabs for replenishing lubricating oil from the main tank to the auxiliary tank. (11) ES is an engine stop signal.

Replenishment can be performed automatically, and even if replenishment is stopped due to trouble with the tank, it has a means to automatically issue an alarm and stop the engine when the liquid level drops to a predetermined level. This has the effect of not only preventing engine troubles caused by running out of lubricating oil, but also informing the user that the auxiliary tank has run out of lubricating oil. Since the engine is refueled from a 1" auxiliary tank, it is easy to attach an auxiliary tank to an outboard engine such as a T-taboat with limited space, or to place it nearby. The installation of the tank has the effect of being able to select a location with good space and an upper platform.
