What does the engine model CLR mean?

[LaZoe]

Engine model CLR refers to the EA111 1.6L engine. Differences between engine models CLR and CEA: Both CLR and CEA are Volkswagen engine models. CLR is a 1.6L naturally aspirated engine without turbocharging, while CEA is a 2.0L turbocharged engine. Engine models CFB and CDF: The sixth-generation Golf equipped with a 1.4TSI engine uses model CFB, while the 1.6L version uses model CDF. My understanding is that CDF is naturally aspirated, while CFB features turbocharging with direct injection design!
