Since 2020, the Hycet factory has been producing the 2.0-liter Great Wall GW4N20 turbocharged engine, which is found in popular vehicles like the Dargo and the third generation H6 crossover. Because of its work on the Miller economical cycle, this gasoline engine is unique among its lineup.
The GW4N20, GWE20CB, and GW6Z30 are Hycet motors from the second generation.

Disadvantages of the GW4N20 engine
Since the first kilometer of running, some owners have already voiced concerns about lubricant consumption.
It has carbon buildup on the intake valves, just like all direct injection units.
It’s also important to note that this motor was given an aluminum block rather than a cast iron one.
