Mga experts, is it normal kung nagbubuga ng itim na smoke ang turbo diesel car? Our's is a ford everest 2012. It happens usually at 2nd gear reaching about 2-2.5 rpm. Hatak mode po yun.. It's our first turbo charged car kasi.. Pasenya na po im newbie sa ganitong engine. Nasanay kasi ako sa biglang apak ng acceleration pedal sa civic fd ko pero i don't notice any black smoke(baka dahil unleaded). Hehe
Sometimes even new diesels will smoke if you rev them hard, suddenly. Depends really on the engine.
not an expert but will answer your question. hatak? but not pedal to the medal, yes? then its not normal. usual cause of smoky exhaust for CRDI engine, i assume crdi engine nyo, is bad fuel or dirty diesel.Quote:

diesel engine on the other hand is different, it will have black smoke on upak mode. but not very much like a bus. and as you said your just driving at 2000 to 2500 rpm then it should not exhibit much smoke. as that range is the usual driving range for a diesel engine.
try to drain the present diesel from the tank. fill up with better and newer gas station near you. preferably the big 3. wag muna full tank. try to drive a few kilometers till the old diesel from the pipes are replaced with the new one. gradually the black smoke should be gone.
hope this helps
new ford everest yan sabi mo, common rail na yan, pero hindi pa vgt ang turbo nyan. so may turbo lag. reason for the black smoke.
kahit naman siguro rolls royce na makina ng eroplano pag sobra ang fuel (biglang apak sa accelerator pedal) uusok. walang problema ang engine ng everest mo. yung driver ang problema.
fyi 3rd gen everests are vgt equippedQuote:

it's non VGT i think. Power is just up to par with 3.0L non VGT Fortuner at 163 (vs 156 for the Everest) and 2.5L non VGT Montero at 136 (vs 143 for the Everest). 2.5L VGT equipped Navarra & Grand Starex rates at 174 and Montero is at 178.Quote:

Thanks sa input mga sir.. Sometimes kasi i press really hard on the gas pedal or more like sudden acceleration then shift at 2-2.5k rpm.. Pero sandali lang naman ung smoke.. Just what ive said, nasanay ako sa dating sedan ko..
About the VGT equipped. AFAIK sa FCP vgt na daw ang everest since second gen . Di ko lang alam sa fortuner..
Anyway, vgt or not.. The ford everest's engine still a monster for me. Hehe
Wow! Fortuner's engine tuning is tameQuote:

My Accent smokes just a tiny bit at times at 2-2.5K RPM. I think it's pretty normal.
Smoke will happen due to transient rich conditions caused when you suddenly ask the engine for more power. It happens a bit wi Hyundais, it happens quite a bit with Mitsubishis, it happens with BMW's 250-300 hp 3.0 diesels.
It's nothing to worry about if it's just a short puff.
It depends on the application and to what the engine is designed for.Quote:

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. :nod: 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.
maybe, maybe not. but hey, look at the germans (bmw, mbs etc) diesel engines :)Quote:

i own an Everest too like the OP, and im very happy with it. Smokes too when i floor it. But ive seen others (monteros )do worse.
A well maintained diesel engine actually produces less carbon dioxide than a gas engine.Quote:

Carbon dioxide emissions only tell you how much fuel the engine is burning... In other words, it's a factor of fuel efficiency. Diesels are generally more fuel efficient, but they produce more particulate emissions than gasoline engines... And more carcinogenic emissions than gasoline engines.
So to say they pollute less because they emit less CO2 is kind of misleading. Only rabidly green washed governments consider CO2 a pollutant. They class it as such in order to tax buyers on fuel economy when they should simply just tax fuel to more effectively reduce CO2 emissions. But that's another matter entirely.
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.Quote:
