It comes out through the propeller joint just like an outboard... that's why when you've got the engine running you can see loads of bubbles.
Im sure you read this in the owners manual or the dash, it is not as concerning as they say, however what they are talking about is the fumes that find their way from inside the engine up to the tappet covers (these are the rectangular metal cases that are on both sides of the engine above the cylinders. your tappet covers should have little hose fittings that come out of them and then these hoses should connect somehow to the air intake, assuming you have a carburerated engine. the idea being to recycle these explosive fumes back through the combustion process. if you have a leg drive, the exhaust usually comes out the end of the propeller. hope this helped.
fumes in car,louder then normal engine noise,no power (collapsed muffler or clogged catalytic converter, buzzing noise in exhaust. what did i win? g
You can use it to power a turbo for the engine to gain horse power.
intake compression power exhaust
The strokes of a four stroke engine are intake, compression, power, and exhaust. The engine takes in the fuel, compresses it, uses it for power, and then the excess fuel comes out the exhaust.
Intake compression ***** POWER**** exhaust
intake, compression, power, and exhaust.
internal combustion engine inlet/ compression/ power/ Exhaust
Intake, Combustion, Power, Exhaust
It's a turbine mounted in the exhaust manifold to give more power and smoother running to the engine.
intake stroke, compression stroke, power stroke, exhaust stroke in that order
Turn on the ventilation system before you start the engine; normally on inboard engines which are in a confined space.
