does the lower gear consume much more gasoline than the higher gear at the same throttle level(same supply)?

Question

my motorcycle riding friends wants to know if you can control fuel consumption by means of not pulling throttle level too much? I mean, if you pull less throttle on bikes,does it help in lessening fuel consumption. and that, a full throttle means a fully open carburator valve which means higher fuel consumption.is it right?

Answer 1

Throttle position determines how fast the fuel will empty out the tank. The size of the gear determines the distance the rear wheel will turn with each engine revolution. So, the highest gear that allows the least throttle is the most efficient. You will notice when cruising at highway speed, when you shift to the highest gear the tachometer will drop and the speed will stay the same. Less throttle for same speed is most efficient.

Answer 2

That sounds right to me. The engine will consume the same amount of gas if the engine is turning the same rpm's and the throttle is in the same position. The difference is the speed that you are traveling. In the higher gear you are going faster and getting more miles for the same amount ot gas. The lower gear will get fewer miles for the same amount of gas.

This is a basic approach to the fuel consumption, it does ignore other factors such as wind resistance, but I think that will be minimal when compared to different gears.

Answer 3

If you are at the same throttle level then in the lower gear you will go slower and should use the same amount of gas.
For greatest economy, you should be driving in the highest gear (lowest rpm) that you can sustain the speed. The other tricks are standard including keeping the rpm down while leaving stop signs, etc. It is amazing how much better milage one gets in a car using cruise control and keeping your twitching foot off the gas.

Answer 4

I would think that you would cover more miles in high gear with a redused throttle opening than you would at a lower gear with the very same carburetor opening and rpm. Math would tell you that you'd be covering more miles in high gear than any redused gear even though overall load on the motor would be less. Cars operate the same way as that's the reason for overdriven transmissions.

Answer 5

Engine works by burning gas. customary standard engine works with 4 tiers. First the piston is going down, sucking air in to the cylinder. 2nd, piston comes up and compresses the air, gas is injected in the present day to the cylinder at this element or premixed with air. 0.33 is the artwork stroke, wherein the gas-air mixture is lit with spark (or by compression in diesel) and the explosion pushes the piston down. Fourth, piston comes up and expels the exhaust gases. The Revolutions consistent with Minute tells you the way a lot of those cycles are happening. If the engine spins quicker, greater gas is burned. Gears in gearbox are meant to get the engine run at optimal RPM, the two optimal for gas intake or for acceleration. They function by adjusting the ratio at what speed the wheels spin whilst in comparison with the engine. Then comes the resisting forces. Air and roll resistance. i will't answer your question, for the reason which you haven't any longer reported could the automobile pass comparable speed? if so, the decrease equipment is greater in all risk to consume greater. If how ever we are going slower with the 1st equipment, and the RPM is comparable because of the fact the better gears, then the decrease equipment is greater in all risk to consume much less. that's because of the fact the resisting forces are smaller.

Answer 6

Same RPM and same Load? Then yes it will use more gas then a higher gear. It is all about "Miles Per Gallon".
Think about this. At any given RPM, the engine will consume so many gallons per hour at that RPM no matter what the vehicle speed. Engine load is the only other factor to consider.

Answer 7

shift early and keep your RPMs low, and you conserve fuel. Since high RPM = more throttle, what you say is true too.

Its a bike though... you worried about mpg?!?!
