Exhaust gases are generated from the combustion chamber after the air-fuel mixture is burnt through the Power Stroke. These exhaust gases are "thrown out" in the combustion chamber through the Exhaust Stroke. The exhaust gases, including NOx, move through the Exhaust Valve, the Exhaust Passages and finally towards the atmosphere over the Exhaust System. The bridal photograph to the left illustrates a good example of high fashion wedding photography. The picture resembles a perfume advertisement with its ethereal quality and artistic pose, yet it captures the bride and the quality of the dress to perfection.
