    Crank Shaft

    Hi friends,
    Ever wondered of a crank shaft?
    Well this is a single one piece casting or a forged part.The material is heat treated alloy steel.The crankshafts may be unbalanced.So to balance them we usually place dead weights also called as counter weights.The crankshafts of some V6 engines have crank pins which have spread out.It is also called as a splayed crank pin.This crank pin is split in two parts.To balance out-balance conditions each rod is provided with its own crank pin.
    The front end is connected with Gear or sprocket which drive
    1.Camshaft
    2.The pulley which is actually belt driven and
    3.Vibration Damper.
    While the output side is as usual attached with a flywheel.
    Usually an engine which is accommodated with electronic engine control or simply EEC has a timing disc mounted on crankshaft.
    I think I have already explained the use of sensors as to how the ignition system knows about piston positions
    So great studying.And please do correct me wherever I am wrong.Ciao

    See for the definition of crank I won't tell you. We are here to discuss the concepts. But it is a link that transmit power.
    A crankshaft has cylinders mounted on on it. It is very crooked in shape with lots of bends etc. so that when it rotates, the cylinders will have a reciprocating motion.

    we can say crankshaft is the backbone of the ic engine.its function is to convert reciprocatry motion of the piston in to the rotory motion. it has one or more eccentric portion called crank.the part of crank to which bigger end of the conn.rod attached is calledcrankpin. crankshaft is made of special steel alloy...........how was it???/

    ya i can solve ur confusion.it convert reciprocating motion into rotry with the help of conn. rod not lonely ok mr.
