The terms nacelle and cowling are both used. Your photo captures a phenomenon (witnessed at sunrise and sunset) that some have mistaken for engine fires in the past. I know of one aircraft at CDG that had a full evacuation after the setting sun reflecting off the engine created the illusion it was on fire.
