    ABSTRACT

    NANO2one billionth of one and one third of micro, to be precise 10-9m. Nanotechnolog is

    m!ch disc!ssed these das as a emerging frontier " a realm in #hich machines operate at scales

    of billionth a meter. It is act!all a m!ltit!de of rapidl emerging technologies based !pon the

    scaling do#n of e$isting technologies to the ne$t le%el of precision and miniat!ri&ation. In the

    field of nano technologies researchers are enth!siastic abo!t its potential applications in fields

    s!ch as energ, medicine, electronics, comp!ting and materials. Of late, one of the emerging

    aspects dealing Nanotechnolog in mechanical field is the internal comb!stion engine on a nano

    scale, #hich #e ha%e chosen as o!r area of interest. 'eat engines ha%e e%ol%ed from e$ternal

    comb!stion engines to internal comb!stion engines and the hot off the bloc( is the nano internal

    comb!stion engine.

    length from the bac( plate to #asher is less than an inch. )here are no e$otic materials re*!ired

    It has high precision, cost effecti%e, high speed +!p to 0000rpm.)he %ario!s applications can be

    spotted from race cars to space crafts. It can also be applied to %ario!s fields li(e agric!lt!ral
