From what I understand, the evap system works when refueling and when the car is running.
When refueling the excess air in the tank is forced through the charcoal canister, scrubbed and clean air is released through the air drain. When running, vapors in the tank are sucked into the canister and purged to the engine. My question is, if the vapors pass through the canister wouldn’t it be clean air (non-combustible) that is being purged to the engine?
Thanks for any clarification!
