What is and Exhaust System

Basically, an exhaust system is a tubing used to guide waste exhaust gases away from a controlled combustion inside an engine or stove. An example of such system is a Gibson Exhaust System.

The whole system projects burnt gases from the engine that includes one or more exhaust pipes.

Taking into consideration the overall design, the exhaust gas may flow through anyone as follows:

1. Cylinder head and exhaust manifold.
   
2. A turbocharger to increase engine power
   
3. A catalytic converter to reduce air pollution.
   
4. A muffler or silencer to lower the noise.
   

DESIGN CRITERIA
In order to carry toxic and/or harmful gases from machine users, an exhaust pipe must be carefully crafted.

If they are not given enough ventilation to the outdoors, within no time indoor generators and furnaces can quickly fill an enclosed place with carbon monoxide or other poisonous exhaust gases.

Since gases from most machines are extremely hot, the pipe must be heat resistant.
In a stationary structure, a chimney serves as an exhaust pipe.

MOTORCYCLES
Most motorcycles have a visible exhaust system and are chrome-plated.
Siamese exhaust pipes are used on a two-cylinder motorcycle, where both cylinders blow into the same exhaust pipe and connect with a crossover.

TRUCKS
In most trucks, exhaust system is highly visible. The silencer is surrounded by a perforated chrome plated sheath, so that it prevents you from getting burned incase you touch the silencer.

TWO STROKE ENGINES
With regards to two stroke engines, a bulge in the exhaust pipe called an expansion chamber uses the exhaust pressure to create a pump that squeezes more air and fuel into the cylinder during the intake stroke, thus providing increased power and fuela substance that can be consumed to produce energy efficiency.

OUTBOARD MOTORS
The exhaustsystem consisting of the parts of an engine through which burned gases or steam are discharged system is a vertical passage through the structure of the enginemotor that converts thermal energy to mechanical work in outboard motors.
Also, it minimizes out-of-water noise that blows underwater through the middle of the propeller.
