no he does not smoke.
of course it emits "smoke" you mean exhaust? it has to go somewhere, if it's a propeller plane it has an exhaust just like car, if it's a turbine, it has an exhaust outlet, if it's a jet engine, the exhaust is self explanatory
what is the worst for your health breathing in tobacco smoke or exhaust fumes
probably an exhaust leak, at or near the exhaust manifold
emissions and exhaust
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
A puff of smoke that's in a shape of the exhaust pipe A gasket/seal that is shaped like a donut. They are used between the manifold and the exhaust pipe.
how can i get black exhaust smoke stuck on my dual exhaust
the smoke that comes out of a exhaust pipe is supposed to be white
It's fuel exhaust, like the exhaust from a car. Like a car the largest component of rocket exhaust (at least from the combustion of its hydrogen fuel) is water, The white "smoke" you see is essentially steam like you get from a hot kettle/.
sounds like you have head gasket problem if the exhaust smoke is white in colour then its engine coolant if its blue smoke then its burning oil you will need to get the engine pressure tested at a garage.
Sounds like you have a coolant leak.
