Abstract: A coupling arrangement within an evaporative loss control system is provided. The coupling arrangement includes a first conduit coupled to an air intake duct of a combustion engine at a first junction and to an atmosphere conduit of an evaporative loss control device at a second junction; and at least one valve located within the first junction, along the first conduit between the first junction and the second junction, or within the second junction, the at least one valve being selectable between a capture position and a purge position, the capture position opening the first conduit to gaseous flow between a canister of the evaporative loss control device and the air intake duct, the purge position closing the first conduit to gaseous flow between the canister of the evaporative loss control device and the air intake duct.

Abstract: A method for cleaning carbon black before using it as material for supercapacitor electrode. The method consisting on washing the carbon material with an acid choosen in the group consisting on hydrochloric acid, nitric acid, citric acid, formic acid, acetic acid and oxalic acid. A supercapacitor includes an electrode comprising activated carbon and carbon black particles containing less than or equal to about 100 ppm of calcium. A method includes treating base carbon black particles to form treated carbon black particles containing less than or equal to about 100 ppm of calcium; and using the treated carbon black particles to form an electrode of a supercapacitor. Carbon black particles having a Brunauer, Emmett and Teller (BET) surface area ranging from 650 m 2 /g to 2,050 m 2 /g, and comprising less than or equal to about 100 ppm of calcium.
