Black smoke from brand new turbo diesel car

it's VGT for both 2.5 and 3.0 everests. The Fortuner too is VGT equipped.

Wow! Fortuner's engine tuning is tame

It's the boosting perhaps.

so if the everest is already vgt, then does that mean the koreans are better than the amreicans since their non-vgt diesels (the old grx crdi) does not smoke when you floor the pedal? also their vgt- diesels (gen 2 sta fe) also don't smoke no matter how aggressive you drive. hmmm...

My Accent smokes just a tiny bit at times at 2-2.5K RPM. I think it's pretty normal.

It depends on the application and to what the engine is designed for.

Regarding Everests being smokey in sudden-WOT application, i assume that it's fuel governor and AFR is tuned richer in that kind of scenario. It injects more fuel to the combustion chamber as you floor the accelerator. That sudden change in AFR only last for milliseconds until the engine could cope up with what had just happen. Also, this is also to help cool the engine in that sudden engine acceleration.

This is a normal tuning norm in engines. If you happen to see some highly modified tuner cars, you'll notice that they smoke a bit in sudden-WOT more usual in a turbocharged engine.

I guess the Koreans tuned their engines more differently. Though i see few 2nd gen non-ReVGT SF's smoking just a tiny bit when accelerating. Though i have yet to see both to smoke a lot even in normal driving. The most common smokers i see are Toyota D4D's, Isuzu Ddi's and Mitsu DiD's.

I cannot recall seeing Everests that are emitting black smoke. Brand new crosswinds, yes. Isuzu alterras, barely. Quite a number of D4Ds, but I was surprised to see at least 2 BNew Montys (No plate yet and one with a V badge), Smoking worse than a crosswind.

My Everest wasnt smoking on its first year despite being regularly maintained, but after that... still ive seen monteros do worse

kayo naman nasanay lang sa gas car yung TS. baka yung sa tingin at pakiramdam niya na apak sa pedal sa gas car nya dati eh hindi nagpproduce ng usok... eh sa diesel nya ngayon eh nageemit ng usok na sa tingin nya eh parang parehas yung apak nya sa gas fed car nya dati.

diesel governors (conventional) inject more diesel than what is required when accelerating to give it the extra kick. somehow, sa mga new tech diesels like common rail, etong problem na ito is much lesser.

kung bakit kasi naimbento pa yang vgt na yan.....kay simple ng buhay nung fixed geometry pa lang.

Isuzu vehicles have this problem with their DI's kaya mausok kahit bago pa lang. I wonder if they want to do something about it.
