Which vehicles seal the tank at higher pressure?

  • A.Conventional vehicles, whose engines run continuously and therefore purge the canister more often than a hybrid
  • B.Nothing
  • C.Plug in hybrids, whose engines run so little that vapour must be contained in a pressurised tank instead of purged
  • D.Hybrids with limited purge opportunity

Answer: D

A hybrid engine may run too little to purge the canister. The last option explains exactly that difficulty and its solution, which makes it a correct and more instructive version of the same answer. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. Checking which component actually carries the load settles most questions of this kind at once. A single measurement chosen to respond to the one asymmetry beats several that respond to shared behaviour.
