Patent number: 7634347Abstract: A refuelling system for a vehicle having a combustion engine. The refuelling system includes: a fuel tank; a canister configured to adsorb fuel vapor generated inside the fuel tank; a canister drain cut valve coupled to the canister and configured to discharge air; an ignition sensor configured to detect whether the ignition of the combustion engine is switched on or off; and a refuelling controller configured to open the canister drain cut valve when the ignition sensor detects that the ignition of the combustion engine is switched off. A method for refuelling a motor vehicle can use the refuelling system.Type: GrantFiled: October 27, 2005Date of Patent: December 15, 2009Assignee: Inergy Automotive Systems ResearchInventors: David Hill, Saurin Mehta
