Pick up trucks with heavy exhaust smokes
The black smoke emitted by diesel engines is primarily composed of particulate matter (PM), which includes largely soot (i.e. carbon particles. These are tiny carbon-based particles resulting from incomplete combustion of diesel fuel. Also you get unburned hydrocarbons, that’s unburnt fuel that that escaped as vapor. Carbon monoxide, another result of incomplete combustion. Sulphur compounds; diesel still contains sulphur but it less common now due to fuel regulations. Ash that comes from additives or impurities, especially in older engines and engines burning low-quality fuel. This smoke is visually polluting but nevertheless quite harmful to health, like crop burning it contributes to respiratory and cardiovascular diseases. Most recent diesel engines use diesel particulate filters (DPFs) and catalytic reduction to reduce or eliminate visible smoke. If a diesel engine is poorly maintained it is likely to emit black smoke, this is common on commercial vehicles... However pickup truck racing is very popular in Thailand and many youths like to emulate the tuning that these vehicles undergo. The result on highly tuned diesel is almost always a lot of extra black smoke – so these young bloods love to leave a trail of black smoke as they accelerate away as a sign of the tuning the vehicle has had. There are emission laws but they are inconsistently enforced by a relatively untrained police force. As a footnote it’s worth bearing in mind that gasolene engines emit just as many dangerous pollutants but because they can’t be seen, them people don’t complain. -

Crime Australian Man Detained for Carrying Grenade Rounds at Phuket Airport
They may have been relics from old wars, explosive parts removed so only empty shells. People collect this kind of stuff all the time. Of course, if they were not properly prepared then it would be very dangerous to handle such things, especially as they appear to be very old if those images are the items in question here. -

The High Cost of Breathing
NO ... as basic physics tells my, you can't squeeze more air through a small tube, simply because the the opening may be a wee bit larger at one end.
