I'm running a program that is collecting distance/time and fuel consumption/time information from the vehicle.
I can compute acceleration, simply enough:
I can figure out how much fuel was used, and the distance traveled in that last second also.
So the question is, is there a peak efficiency that can be determined from this info? i.e. if one were in the "oval" of the bsfc chart, would it manifest itself in terms of acceleration/fuel consumption:
Or do I need to factor in CdA, velocity, Crr, and weight and come up with a representation of power(or possibly energy) in order to find the most efficient ratio?
Or is just watching the mpg sufficient?!? I don't think it is because that will ever be decelerating.
I'm expecting that there is an optimal throttle setting while accelerating (which may change while accelerating) for accelerating at peak efficiency, and that the program should be able to provide (audio) feedback to the driver to find that setting while driving.
given f=ma and p=fd , I can just use 1 for m, the unit is metros and plug in the distance covered I get: p=ad
then the current relative efficiency is acceleration*distance/fuel
So not sure I can figure out relative power if we are climbing a hill and not accelerating, but having d in there might correct for that case. Dunno, it would be nice if I could ignore all the wind resistance and whatnot for now.
