Exhaust System - Design Criteria

Design Criteria

An exhaust pipe must be carefully designed to carry toxic and/or noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with carbon monoxide or other poisonous exhaust gases if they are not properly vented to the outdoors. Also, the gases from most types of machine are very hot; the pipe must be heat-resistant, and it must not pass through or near anything that can burn or can be damaged by heat. A chimney serves as an exhaust pipe in a stationary structure. For the internal combustion engine it is important to have the exhaust system "tuned" (refer to tuned pipe) for optimal efficiency. Also this should meet the regulation norms maintained in each country. In European countries, EURO 5, India BS-4 etc.,

Famous quotes containing the words design and/or criteria:

    Westerners inherit
    A design for living
    Deeper into matter—
    Not without due patter
    Of a great misgiving.
    Robert Frost (1874–1963)

    The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
    Always yield to the Hands-On Imperative!
    All information should be free.
    Mistrust authority—promote decentralization.
    Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
    You can create art and beauty on a computer.
    Computers can change your life for the better.
