  1. Jan 16, 2010 #1
    1. The problem statement, all variables and given/known data

    How many revolutions does a driving shaft of an eight cylinder four stroke engine perform until every cylinder has ignited once ?

    2. Relevant equations

    4 - 8 - 6 - 2

    3. The attempt at a solution

    Moreover, I would like to have information and understand the logical solution of the question.
    Can anyone explain me as detailly as he/she can ?

    If it were a single cylinder, 4-stroke engine, how many revolutions does the drive shaft make per ignition? If you need help understanding engines, try this website:
