Are there any known design flaws in Changan Kalam’s engine o r fuel system that lead to inefficient fuel consumption in Pakistan?

Some users suspect the carburetor o r injector settings are outdated. Has Changan addressed this in newer variants?

Suspected, but not officially confirmed.
Many users and independent mechanics point to:

Old-school carburetor-style injection behavior

Basic fuel mapping without dynamic adjustment

Substandard injector quality

While Changan hasn’t acknowledged a design flaw, patterns of injector wear and poor atomization hint at limitations in engine tech used in Kalam compared to Japanese counterparts.
