Diesel vehicles, send black smoke like a BBQ. Specially, 18 wheelers. And nobdy does anything. Why?

We can't stop!  We just keep going faster and faster and digging in deeper and deeper!  We have to buy stuff.  We have to move stuff.  We need those 18-wheelers going round and round to bring us stuff.  C'mon  people!  Get more stuff!  Stuff, stuff, stuff, stuff, stuff, BEEP BEEEEEP!!! Get out of the way of the stuff!  Make way for the stuff.

A big fire in a barrel. Might also help if you have a train sound. Hobo's like train hopping and all.

when a Tyre heats up it starts to excrete oil from the rubber the smoke is caused by heat generated by the wheel spinning and it is enough heat to burn of the oil Tyre's are made up of a lot of oil

Unleaded fuels-so no lead\nnitrogen compounds come as a result of air combustion in your engine (remember air is approx. 80% Nitrogen).  and you gotta have air to make your engine run.\nSulfur gases can also be a result of this combustion if there is high sulfur content in the fuel. (Shell had a problem with this last year)\nPS. Don't buy into the greenhouse hype, at this point there is NO real evidence either way that fuel combustion makes any difference in the grand scheme of climate dynamics

It is either an attempt to block part of the sun's rays from hitting the earth , to allegedly mitigate global warming (Project Cloverleaf), or another method of poisoning everyone, with the substances used--a variety of chemicals and other substances, including barium, aluminum oxide, microscopic fibers and oil-based products, none of which are intrinsic to normal jet fuel. (To those unfamiliar with chem-trails: I know what normal contrails are.)\nI don't know who They are.

Cops have them too.  Use helicopters.  Require certain high speed models to come with a kill switch like are used on go-cart tracks.  Disabling it would activate a lo-jac type device or ruin the engine.

MC Hummer is a dolt, WMD would infer the DU rounds caused nuclear explosions... \n\nUnexploded DU rounds don't cause illness.  Messing around vehicles that have been destroyed by a DU round does cause illness...\n\nMc Dolt, nice photo's you scum bag, did you write the BS story all by yourself?  I'm retired Army been to Iraq three times and Bosnia and Kosovo both twice.  Seen plenty of destroyed vehicles courtsey of USAF DU rounds and I don't have cancer and neither do my children...  \n\nYou're a typical stuck on stupid liberal.  What part of an unexploded DU round poses no harm is hard for you to understand.  DU rounds are only dangerous after they have hit their target and irradiate the adjacent ground, dirt and dust.  Unfortunately much like yourself, the military has dolts that would approach destroyed vehicles and kick up and breath the irradiated dust.  Too bad you're an ignorant coward and rather run you yap than defend your country....\n\nAs for your links, pure BS...

I AGREE W/ ROWDY.  JUST GOT A DODGE CUMMINS DUALLY, HOOKED UP THE TRAILER AND yyyyyyyyeeeeeeeeeHHHHHHHHHHaaaaaaaaaawwww!

With the air holes closed, there is a shortage of oxygen and the hydrocarbons in the gas do not burn completely. Some carbon is not burnt resulting in soot

sounds like the belt to the blower need lubing up. and the bering need greacing. i cal the gas compnay to come check it out sound like bad barings.

a bad fuel sender can cause this.

None - once it hits my grill!

We use smoke bombs in hvac work all the time. For example inspections.Air leaks etc...

It's a manufacturers joke. Theres also a coil that unwinds in the night that makes you *think* its on four but the internal setting is changed to burnt beyond recognition so your morning gets off to a terrible start.

burnt vegetable oil IS used as a substitute for diesel in vehicles.

he diesel engine is a type of internal combustion engine; more specifically, it is a compression ignition engine, in which the fuel is ignited by being suddenly exposed to the high temperature and pressure of a compressed gas, rather than by a separate source of ignition, such as a spark plug, as is the case in the gasoline engine.\n\nThis is known as the diesel cycle, after German engineer Rudolf Diesel, who invented it in 1892 and received the patent on February 23, 1893. Diesel intended the engine to use a variety of fuels including coal dust. He demonstrated it in the 1900 Exposition Universelle (World's Fair) using peanut oil (see biodiesel).\n\nHow diesel engines work\n\nWhen a gas is compressed, its temperature rises (see the combined gas law); a diesel engine uses this property to ignite the fuel. Air is drawn into the cylinder of a diesel engine and compressed by the rising piston at a much higher compression ratio than for a spark-ignition engine, up to 25:1. The air temperature reaches 700–900 °C, or 1300–1650 °F. At the top of the piston stroke, diesel fuel is injected into the combustion chamber at high pressure, through an atomising nozzle, mixing with the hot, high-pressure air. The resulting mixture ignites and burns very rapidly. This contained explosion causes the gas in the chamber to heat up rapidly, which increases its pressure, which in turn forces the piston downwards. The connecting rod transmits this motion to the crankshaft, which is forced to turn, delivering rotary power at the output end of the crankshaft. Scavenging (pushing the exhausted gas-charge out of the cylinder, and drawing in a fresh draught of air) of the engine is done either by ports or valves. To fully realize the capabilities of a diesel engine, use of a turbocharger to compress the intake air is necessary; use of an aftercooler/intercooler to cool the intake air after compression by the turbocharger further increases efficiency.\n\nIn very cold weather, diesel fuel thickens and increases in viscosity and forms wax crystals or a gel. This can make it difficult for the fuel injector to get fuel into the cylinder in an effective manner, making cold weather starts difficult at times, though recent advances in diesel fuel technology have made these difficulties rare. A commonly applied advance is to electrically heat the fuel filter and fuel lines. Other engines utilize small electric heaters called glow plugs inside the cylinder to warm the cylinders prior to starting. A small number use resistive grid heaters in the intake manifold to warm the inlet air until the engine reaches operating temperature. Engine block heaters (electric resistive heaters in the engine block) plugged into the utility grid are often used when an engine is shut down for extended periods (more than an hour) in cold weather to reduce startup time and engine wear.\n\nA vital component of older diesel engine systems was the governor, which limited the speed of the engine by controlling the rate of fuel delivery. Unlike a petrol (gasoline) engine, the incoming air is not throttled, so the engine would overspeed if this was not done. Older injection systems were driven by a gear system from the engine (and thus supplied fuel only linearly with engine speed). Modern electronically-controlled engines apply similar control to petrol engines and limit the maximum RPM through the electronic control module (ECM) or electronic control unit (ECU) - the engine-mounted "computer". The ECM/ECU receives an engine speed signal from a sensor and then using its algorithms and look-up calibration tables stored in the ECM/ECU, it controls the amount of fuel and its timing (the "start of injection") through electric or hydraulic actuators to maintain engine speed.\n\nControlling the timing of the start of injection of fuel into the cylinder is key to minimising their emissions and maximising the fuel economy (efficiency) of the engine. The exact timing of

when we are burning any thing generally the body releases some gases and especially carbon di oxide and carbon monoxide.\nand in some systems( organic) sooty nad non sooty flames are there.if we observe flame with black smoke it is sooty and if the flame is without that black smoke it is non sooty.\nso,the gases which are released causes the flame to go up.\nas it contains hot gases which are with low density ,they will go up.
