Fuel consumption and speed

  1. Jan 15, 2016 #1
    I was wondering about the amount of fuel used for a given journey.
    My model is that the same journey is made at two different constant speeds
    I have assumed that instantaneous fuel consumption is proportional to the power produced by the engine at that point.
    I an ignoring rolling resistance losses, and considering air drag only.
    I have used power * time as a base for total amount of fuel used for each journey
    Any comments ?
