I have been recommended not to run the two-wheeler (Suzuki Access) at a constant speed (I give a constant throttle in a way that I run essentially at a constant speed of about 40-45 kmph). In fact, I have been told to keep changing the acceleration (smoothly though) for lesser fuel consumption. I want to understand the technical reason behind this claim.
Your question doesn't make much sense.
- For a given set of conditions - selected gear, gradient, load, wind and road resistance - there is a required power to maintain constant speed.
- Since power is a function of throttle position and this increases with throttle rotation then there must be only one throttle position that generates that power.
The graph and topic is discussed further in https://physics.stackexchange.com/questions/57888/why-does-higher-acceleration-minimize-a-cars-fuel-consumption.
