High Pressure Fuel Tank Manufactured From High-Strength Steel Sheets or Advanced High-Strength Steel Sheets With Organometallic Coat

摘要

This invention patent covers a high pressure fuel tank (reservoir) (1) manufactured from high-strength “HSS” or “AHSS” steels with an organometallic surface coat, containing structural elements consisting of structural columns (2) internally fastened by quick couplers welded to the half-bodies, and structural bands (3) that have the same geometric shape as the external surface of the half-bodies and fastened to the tank edges by means of screws on such edges. Such fuel tank (1) contains also an internal fuel ventilation system with a continuous tube (4) interconnecting components, such as: fuel filling stop valves (5), intermediary liquid/vapor separator (6), vent valves (7 and 8), to secondary tube segments (9), as well as an outlet opening (10) connected to an appropriate tubing and linked to the fuel vapor treatment carbon canister system through the outlet opening (11).

主权项

1) “HIGH PRESSURE FUEL TANK MANUFACTURED FROM HIGH-STRENGTH STEEL SHEETS OR ADVANCED HIGH-STRENGTH STEEL SHEETS WITH ORGANOMETALLIC COAT” characterized by a high pressure fuel tank (reservoir) (1) manufactured from high-strength steel “HSS” (“IF—Interstitial Free”) sheets or advanced high-strength steel “AHSS” (“DP—Dual Phase, TRIP—Transformed Induced Plasticity”, “TWIP—Twinning Induced Plasticity”) sheets coated with organometallic coat, containing internal and/or external structural elements consisting of structural columns (2) internally fastened by quick couplers welded to the half-bodies; containing also structural bands (3) manufactured from high mechanical strength materials (“DP” and “TRIP” steels, among others) that have the same geometric shape as the external surface of the half-bodies and are located in critical places and fastened to the tank edges by means of screws on such edges, which compress the packing material (nylon) on the tank edges; in special circumstances, such fastening can be made by means of alternative methods.
