Power losses

  1. Sep 27, 2014 #1
    When dealing with power losses from engine to drive wheel(s) i ignored losses other than straight friction, can cooling and alternator losses be taken as roughly a percentage of the cars engine power ?

    Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    No problem, will research further on the net, thanks though.

    Hi Dean,

    Power losses are energy losses in time. If you assume a constant power of the engine, and also assume a constant cooling and alternator consumption (not constant in reality), then "roughly" those will be a percentage of your engine power.
