Patent number: 11542893Abstract: An evaporative emissions control system includes a first vent valve configured to selectively open and close a first vent, a second vent valve configured to selectively open and close a second vent, a fuel level sensor configured to sense a fuel level in the fuel tank, a pressure sensor configured to sense a pressure in the fuel tank, an accelerometer configured to measure an acceleration of the vehicle, and a controller configured to regulate operation of the first and second vent valves to provide pressure relief for the fuel tank. The controller is programmed to determine if a refueling event is occurring based one signals indicating the fuel level is increasing, the pressure in the fuel tank is increasing, and the vehicle is not moving, and open at least one of the first and second vent valves based on determining the refueling event is occurring.Type: GrantFiled: August 16, 2021Date of Patent: January 3, 2023Assignee: Eaton Intelligent Power LimitedInventors: Max Russell Franklin, Nikhil Nahar, Vaughn Kevin Mills, Mark Beaupre, Matthew Memmer, Steven L. Ambrose, Robert P. Benjey

Patent number: 11491866Abstract: A vent shut-off assembly configured to manage venting on a fuel tank configured to deliver fuel to an internal combustion engine includes a first liquid vapor discriminator (LVD), a main housing, a first poppet valve assembly, a pump and an actuator assembly. The first LVD is disposed in the fuel tank. The main housing selectively vents to a carbon canister. The first poppet valve assembly has a first poppet valve arranged in the main housing. The pump selectively pumps liquid fuel from the main housing. The actuator assembly is at least partially housed in the main housing and includes a cam assembly having a cam shaft that includes a first cam and a second cam. The first cam has a profile that one of opens and closes the first poppet valve fluidly coupled to the first LVD.Type: GrantFiled: August 27, 2020Date of Patent: November 8, 2022Assignee: Eaton Intelligent Power LimitedInventors: Vaughn K. Mills, Jeffrey B. Smith, Dan L. Pifer, Nikhil Nahar, Clark Fortune, Steve C. Holmquest, Sagar Dilip Pingale, Curtis Moy

Publication number: 20220268223Abstract: An evaporative emissions control system configured for use with a vehicle fuel tank includes a purge canister, an accelerometer, first and second vent tubes that terminate at first and second vent openings, a first vent valve, a second vent valve, a vent shut-off assembly and a control module. The accelerometer senses acceleration in an x, y and z axis. The first vent valve is fluidly coupled to the first vent tube. The second vent valve is fluidly coupled to the second vent tube. The vent shutoff assembly selectively opens and closes the first and second valves. The control module estimates a location of liquid fuel based on the sensed acceleration from the accelerometer and determines which vent opening is one of submerged and about to be submerged based on the estimated location of the liquid fuel. The control module closes the vent valve associated with the determined vent opening.Type: ApplicationFiled: February 22, 2021Publication date: August 25, 2022Applicant: Eaton Intelligent Power LimitedInventors: Nikhil Nahar, Sudeep Motilal Solanki, Max Russell Franklin, Vaughn Kevin Mills, Mark Beaupre, Matthew Memmer, Robert Andrew Dayton

Patent number: 11267334Abstract: A method for operating an evaporative emissions control system for use with a fuel tank that stores and delivers fuel to an internal combustion engine is provided. A vent shut-off assembly is provided that selectively opens and closes at least one valve to provide overpressure and vacuum relief for the fuel tank. The vent shut-off assembly selectively vents to a purge canister. The at least one valve is closed whereby vapor is precluded from passing from the fuel tank to the purge canister. A purge event is performed wherein dedicated fresh air is drawn into the purge canister and delivered from the purge canister to the engine.Type: GrantFiled: May 1, 2020Date of Patent: March 8, 2022Assignee: Eaton Intelligent Power LimitedInventors: Jeffrey B. Smith, Vaughn K. Mills, Daniel Pifer, Nikhil Nahar, Steven Ambrose, Max Franklin
