The internal combustion engine

  1. Nov 13, 2016 #1
    1. The problem statement, all variables and given/known data
    Hi , I'm struggling with new paragraph about internal engines.
    When four-stroke internal combustion engine spins crankshaft 100 times , piston does 300 ticks.
    How many cilinders does engine has?

    2. Relevant equations
    I don't know how to create equation to calculate that , i need help.

    3. The attempt at a solution
    None , i don't have equation

    Hi Ugnius! :oldsmile:

    A four-stroke engine has 1 ignition in every 2 turns of the crankshaft (intake - compress - ignition - expand - exhaust).
    It's the ignition that gives the tick.
    So if we'd have 1 piston, we'd have 50 ticks, but instead we have 300 ticks...
