Hiya folks, ive seen heaps of pickup trucks spewing those black smokes from their exhaust, 

is there some malfunction with their engine for this occurr? 

ive seen like motobikes behind these trucks and get blasted with black fumes possibly cause some lung cancer and stuff?

im sure breathing those smokes or gettign in to ur eyes and clothese aint good for health

It looks cool.

Engines are retuned to provide 0.0001% extra power

Possibly, if it is an old worn out vehicle.

 

Newer vehicles, Diesel tuners dump more fuel in to make more power, the black smoke is unburnt combustion.

 

My Douche-Max rolls lots of coal, More Smoke, More Poke.

I've heard it's deliberate because they think the smoke looks cool.  I'm not sure about adding power.

They're getting a concentrated dose, but you're getting a pretty good amount whenever you're outside without a mask on.

I'm a cyclist in Thailand and I get blasted with smoke in the face all too often (twice today actually!) and the worst is when you're going up a mountain going slow and breathing heavy. 

 

Usually it's just people that can't afford to have a truck but need it for work and are hauling heavy things. These things are so run down it doesn't surprise me.

 

The ones that get me are all the SUVs that don't even look that old yet are spewing smoke. Of course this is illegal they like everything else they simply do not enforce it. If you can afford that SUV you should be able to maintain it or be taken off the road out of respect for the rest of us.

Never saw this in the US. I thought they weren't changing their oil or something. So many people have nice cars but it's all debt so can they really afford to maintain the cars? Probably not is my guess.

If only Thailand had a police force!  I bet the number of deaths from pollution dwarfs Covid & daily accident figures.

I used to get pulled over at random inspection points around Bangkok when I drove my vintage diesel Mitsubishi Cyclone.  One of the cops would hop in and tap the throttle, with another watching the tailpipe.

 

If I spoke Thai, they'd have probably let me tap the throttle.  (Or "rack" as appropriate for diesels)

 

Then they'd send me on my way.

You see it in the US but they won't go far without being pulled over and warned to get it fixed. It's mostly vehicles with extreme mileage where oil gets past the rings, so it needs major work, which most here can't afford. It can also be a bad fuel/ air mixture. Everyday you see all types of vehicles smoking and are never pulled over, as far as we can see, as they pass the police just like the countless without helmets. Just like back home, you'll see people with a run down house but a Cadillac or nice pickup.

Yep, folks just down the road from us live in a rusty tin shack with plastic taped over the unglazed windows, yet have two new low-rider pickups in front with extra wide tires and ground effects and undercarriage LED's and boomboom system.

 

Priorities.

 

Reminds me of living in Albuquerque.

How do they get around the yearly test?

 

Don't tell me.........Bht 500.

Fun facts to know and tell... 

 

Diesel power ratings are based on the onset of excess smoke from the exhaust.  They can make more than their rated power, but only by rolling some coal. Which is generally frowned upon by polite society.

 

Who'd a known that some of those college ME labs from over 45 years ago would still be stuck in memory.

100 baht is often enough for minor tests.

 

Here a pickup with illegally wide tires showed up at the inspection point, worker rented some fender flares, taped on for the 5-minute safety inspection.

 

 

100 baht likely enough to get the minimum wage worker to leave the smog sensor hanging over the bumper instead of inserted into the exhaust.

 

The big bahts come when you have a refurbished double-decker bus with illegal CNG tanks hidden throughout the passenger compartment, need to offload a couple tons of substandard steel, or accidentally mow down a cop.

Dirty/clogged fuel injectors are the most likely cause. Yes, diesel particulates can increase the risk of lung cancer.

 

The difference between Thailand and Malaysia is obvious, I have never seen a bus, truck or car blowing smoke there. For all I know, there are death squads operating that drag errant drivers out of their vehicles, and execute them on the spot.

Eh?

The idiots here 'over-clock' their pickups...  usually with a cheap chip-set installed to remap the ECU of the engines fuel management systems.

 

Theoretically, it means more fuel is injected which means better performance, in practice it means aggressive ECU remapping causes increased fuel delivery beyond what the air intake can handle, this causes unburnt diesel to exit the exhaust as black soot / smoke... 

 

 

So basically, its a bunch of tools trying to make their diesel engine faster without knowing what they are doing.

no yearly test until they are 7yrs old.

I read ages ago they have something fitted that ejects oil into the system when they accelerate,

It is a bypass head gasket.

Yeah cause the piggy backs (not chip sets)  add more fuel but the owners do not add the extra's required.

 

My Douche-MAX runs a stand alone MoteC ECU compound turbo's// big intercooler/Injectors/Exhaust.

Makes very decent power with very little smoke.... I do a have a "roll coal" button though !

how does that work ?

I think most diesels that "smoke" have worn out injectors - not expensive to replace but I guess saving a few Baht is preferred to saving the health of their (and other's) children 

I would just like to know (I do really) how these vehicles pass the annual Thai MOT.

The oil bypasses the gasket.

In my opinion its just unburnt fuel.Look at the driver, it will be a younger (under 30) Somchai and he'll probably have his foot to the floor.

One eye will be be in the rear view mirror because he thinks its cool for everyone to see the black smoke cloud and people will think he's got a souped up truck.

Same thinking for the guys who remove the baffles on their Honda Wave.

The head gasket is there to stop engine oil, coolant and combustion gasses mixing together.

 

Please explain further, your claim make zero sense.

Your failure to get the joke makes less sense.
