Problems solved by technology

Like this, if DME fuel is stored in a fuel tank for LPG fuel, as the storage time elapses, there will be a problem that the liquid level of DME fuel stored in the fuel tank cannot be accurately measured.

Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0048] First, a immersion test was performed as a preliminary test for studying the material for molding the DME fuel tank buoy of the present invention, and the test results will be described.

[0049] As the buoy installed on the liquid level display device or the overfill prevention device installed in the fuel tank storing LPG (liquefied petroleum gas) fuel, as mentioned above, foam rubber (foamed nitrile rubber) is generally used. moldings. This is because foamed rubber has relatively low density and relatively high tensile yield strength, so buoys molded from foamed rubber can be molded to have a required specific gravity lower than the density of LPG fuel, and can fully withstand the storage of LPG. The compressive strength of the internal pressure of the fuel tank. However, since the foam rubber used in the fuel tank of LPG fuel permeates DME fuel, t...

Abstract

The invention provides a DME fuel tank used float disposed in fuel tank for storing DME fuel capable of floating with the liquid level correctly and stably. The float is made of PPS resin or synthetic resin material using PPS as main component, while the material is hollow body (20) with specific gravity below 0.5, compressive strength above 1.8MPa, and having air-tight hollow part (18). Thereby, the float can achieve excellent separating performance that the DME fuel can hardly immerge, can float on the liquid surface of DME fuel and can sustain the inner pressure of the fuel tank. The DME fuel tank used float (10) can float on the liquid surface of DME fuel correctly and stably for long tim.

Description

technical field [0001] The present invention relates to a buoy for a DME fuel tank that floats with the liquid level of DME fuel, and the buoy for a DME fuel tank is arranged in a liquid level indicating device installed in a fuel tank that stores DME (dimethyl ether) as fuel and / or in an overfill prevention device. Background technique [0002] For example, in recent years, with the strict control of exhaust emissions from vehicles such as automobiles, the number of vehicles using liquefied gas fuel for the purpose of reducing pollution tends to increase. As this liquefied gas fuel, liquefied petroleum gas (hereinafter referred to as LPG) fuel is mainly used, but dimethyl ether (hereinafter referred to as DME) fuel has also been paid attention to. This DME fuel has a high cetane number and has the advantage of being able to reduce the emission of PM and NOx very little, and it is expected to be a low-pollution measure. In addition, as a fuel tank for storing DME fuel, the...
