Explosion versus Deflagration

  1. Oct 27, 2012 #1
    Hi all,

    I was wondering if someone could please clarify the following for me. I read that in a gasoline engine there is no shock-wave in the detonation of gasoline. If there is no shock-wave, then how is the piston pushed down? Thanks in advance for the help

    I assume the combustion of fuel heats the compressed air, causing it to expand and push the piston down. That sound right?
