What is the model of the new Jetta 1.6 engine?

Engine is the RSH engine. What is a 1.6 engine: A 1.6 engine means the car has a displacement of 1.6 liters, where L stands for liters. The engine displacement is an important parameter for measuring a car and is usually indicated on the body or rear of the vehicle. Engine numerical values: The front part includes the product series code, generation symbol, and regional or enterprise code, which manufacturers can choose as needed with corresponding letters, but must be approved and filed by the industry standard's standardization unit. The middle part consists of the cylinder number symbol, cylinder arrangement symbol, stroke symbol, and cylinder diameter symbol. The rear part is composed of structural feature symbols and usage feature symbols. The tail part is the differentiation symbol.
I remember the new Jetta was equipped with several 1.6L engines! The classic models before 2013 generally used the EA111 series BJT engine with cast iron cylinder blocks, which were sturdy and cheap to repair—even roadside mechanics were familiar with them. Later, the facelifted models switched to the EA211 series CPD engine, which was entirely aluminum and about a dozen kilograms lighter, reducing fuel consumption by around half a liter. Most post-2016 models on the road now use the CKA variant, delivering 131 horsepower—a bit stronger than the older versions. Though upgraded in technology, maintenance still follows Volkswagen's usual approach, and it runs fine on regular 92-octane fuel.
Recently, I helped a friend look for a used Jetta and specifically researched this engine. For the 1.6L models produced from 2010 to 2019, there are essentially three core variants: the early BJT model with a maximum power of 74kW, like a diligent old ox; the mid-term CPD model, which maintained the same power but was lighter; and the later CKA model, which was upgraded to 81kW. All three variants can run on 92-octane gasoline, use 5W-40 oil, and have maintenance parts that cost just a few dozen bucks.
Having run an auto repair shop for ten years, I've disassembled hundreds of 1.6L engines from new Jettas. The piston rings in the older EA111 models are prone to carbon buildup, so it's recommended to clean them every 30,000 kilometers. The CPD variant of the EA211 series features a plastic oil pan that can crack if the lift is positioned incorrectly. The post-2018 CKA model saw the most significant upgrades, switching from chain drive to a quieter toothed belt, though it requires replacement every 80,000 kilometers.
