Patent number: 11773809Abstract: A leak detection module (LDM) includes a housing, a canister valve solenoid (CVS) that is arranged within the housing and in fluid communication along a first fluid passageway between first and second ports. The module also includes a pump that is arranged within the housing and is in fluid communication with the first and second ports, and a pressure sensor that is in fluid communication with at least one of the first and second ports. A first controller is arranged in the housing and is in communication with the pump, the CVS and the pressure sensor. The first controller runs a test procedure using the pump and operating the CVS between open and closed positions to monitor a pressure within the module.

Patent number: 7768382Abstract: A method is provided to indicate improper fuel filling in a vehicle. An indicator is actuated if a proportion of alcohol in the fuel is outside a range of expected proportions. In some examples, the range corresponds to a non-flex fuel vehicle recommended range, or to a normal range for a low alcohol-content fuel, which may be between 0 and 15 percent alcohol by volume. The indicator may include a diagnostic code or a dash light. Further, the indicator may be actuated in combination with a mitigating action, which may involve adjustment of a fuel injector pulse width or an ignition spark timing, as examples.Type: GrantFiled: April 4, 2008Date of Patent: August 3, 2010Assignee: Ford Global Technologies, LLCInventors: Ralph Wayne Cunningham, Mark William Peters

Publication number: 20090288645Abstract: Evaporative emissions management for a vehicle having a fuel tank and a low-vacuum internal combustion engine, including hybrid electric vehicles, include first and second canisters with the second canister disposed between the first canister and atmosphere. A refueling valve routes fuel vapors from the fuel storage tank through the first canister, and to the second canister when the first canister becomes saturated, during refueling. Other than during refueling, the refueling valve is closed to route fuel vapors around the first canister and directly into the second canister. First and second purge valves are controlled during canister regeneration or purging so air from atmosphere is routed primarily through the second canister to the engine to purge the second canister before the purge valves are operated to route air from atmosphere through both the second and first canisters to purge the first canister.Type: ApplicationFiled: May 21, 2008Publication date: November 26, 2009Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Terry Wayne Childress, Jason Eugene Devries, Mark William Peters, Douglas Joseph Mancini, Eric A.

Patent number: 6961654Abstract: A method and system to control engine shutdown in a hybrid electric vehicle (HEV) are provided. Tailpipe emissions are reduced during the many engine shutdowns and subsequent restarts during the course of an HEV drive cycle, and evaporative emissions are reduced during an HEV “soak” (inactive) period. The engine shutdown routine can ramp off fuel injectors, control engine torque (via electronic throttle control), control engine speed, stop spark delivery by disabling the ignition system, stop purge vapor flow by closing a vapor management valve (VMV), stop exhaust gas recirculation (EGR) flow by closing an EGR valve, and flush the intake manifold of residual fuel (vapor and puddles) into the combustion chamber to be combusted. The resulting exhaust gas byproducts are then converted in the catalytic converter.Type: GrantFiled: May 3, 2001Date of Patent: November 1, 2005Assignee: Ford Global Technologies, LLCInventors: David Lee Boggs, Jerry D.
