Wow are those older versions of the H-6? That would explain why they look like flying coal mines :/

It's mostly because they're flying at low altitude, the engines aren't as efficient I think.

Even some modern commercial airliners still produce visible smoke at low altitude. Certainly, military aircraft do. B-52 is infamous for it.
There's less smoke at higher altitudes of operation.
