Embodiment Construction

[0084] first note Figure 1A , which schematically illustrates a fuel system (generally referenced 10 ) according to a first example of the disclosed subject matter, comprising a fuel tank 12 equipped with one or more (though typically several) sensors 14 , The sensor 14 is associated with the fuel tank 12 . A fuel tank isolation valve (FTIV), generally designated 16 , is selectively disposed between fuel tank 12 and canister 18 via first flow path 20A and / or second flow path 20B, as will become more apparent herein.

[0085] FTIV 16 includes: a normally closed solenoid assembly 24 that selectively opens first flow path 20A; and an integrated controller 28 that receives parameter signals generated by one or more sensors 14 (wired or wireless, as indicated by dashed line 25 schematically shown), and then generate an actuation signal in the form of an opening signal to the solenoid assembly 24, thereby selectively opening the first flow path 21A between the fuel tank 12 and the ...

Abstract

A fuel tank isolation valve (FTIV) is provided, configured for being disposed in fluid flow communication with a fuel tank and a carbon canister of a fuel system, the FTIV including an integrated controller and a solenoid coupled to a valve, the solenoid being movable between a normally closed position in which the valve is closed and prevents fluid communication through a first flowpath through the FTIV, and an open position in which the valve is open and allows for fluid communication through the first flowpath, the integrated controller being configured for generating actuation signals to the solenoid, responsive to parameter signals received from one or more sensors associated with the fuel tank. A sensing system for use with a fuel system is also provided, the sensing system includingthe FTIV and at least one such sensor. A fuel system is also provided, including a fuel tank and a carbon canister, and also including the sensing system for use therewith.

Description

technical field [0001] The subject matter of the present disclosure relates to fuel tank isolation valves (FTIVs), particularly for use with hybrid vehicle systems. Background technique [0002] References considered to be relevant to the subject matter of the present disclosure are listed below: [0003] -US 9,026,292 [0004] -WO 2015 / 114618 [0005] The acknowledgment of the above references herein is not to be inferred to imply that these references have any relevance to the patentability of the subject matter of the present disclosure. [0006] Certain types of vehicles, such as hybrid electric vehicles (HEV) or plug-in hybrid electric vehicles (PHEV), are provided with a sealed fuel system including a fuel tank isolation valve (FTIV) located between the fuel tank and the carbon filter. The FTIV is biased and normally in a closed position and operates to selectively open fluid communication between the tank and canister. Opening the FTIV can control the pressure ins...
