How many motorcycle speed saving fuel?
Release date:2019.07.31

      The best fuel economy is burning the least fuel to get the longest mileage. For example, some 125 kilometers use 3 liters of oil, while others run 100 kilometers with 1.8 liters. The latter is more fuel efficient than the former. Fuel consumption and speed indeed have a certain relationship, mainly because of the speed and engine speed and load, but this is not a relevant and direct ratio relation, is more complex function relation, the engine operating at a certain speed condition, conversion efficiency is the highest, if you can make motorcycle engine fixed under the rotating speed and load running, this is also the most fuel-efficient motorcycle's speed, the difference is the point for each model, and hung up the high and low speed drive is generally recognized as the most fuel efficient, that is to say, on the lowest speed under low load cycling, and to ensure that the engine is running smoothly, There won't be any jitter.

1, according to Newton's second law, power = force * speed, engine combustion work output process, is the output of a certain power process, the power to overcome a certain resistance, but also to ensure a certain speed. The operating point of an engine corresponds to a certain speed and load (which can be understood as resistance). Since the engine is not a linear process of doing work, the maximum power point, maximum torque point and optimal efficiency conversion point are not the same. That is to say, the car is not the fastest to save fuel, not the slowest to drive the lowest fuel consumption, but there is a so-called economic speed range, and to ensure that in certain road conditions can be completed.


2, most of the emissions from motorcycles, 125 and 150 the economy which is about 50 kilometers/hour, different will have certain difference, if you stay at 80 kilometers per hour to ride a bike, fuel consumption is relatively increases to 15%, if the speed is close to 100 km/h, fuel consumption will increase 30%, in turn, also about the sense of fuel increase at low speed.

3, gear design, a lot of times according to the load to switch to consider, the higher the gear, should be faced with the situation to choose the smaller load, such as uphill must choose low gear, because uphill resistance is equivalent to high load. Obviously, if you ride in a low gear on a level road, you're not as efficient as a high gear, so you get more gas mileage. In addition, the faster the speed, the cubic relationship of wind resistance consumption, fuel consumption will increase dramatically, blind run faster fuel consumption will also become much higher.


4, choice of high-grade low speed is one of the most fuel efficient approach in theory, but many roads are not allowed to do you like cycling, suddenly to a small slope, speed decreased, you have to shift or adjusting throttle, these practices can create speed changes, and the engine speed, than the uniform time consumption, so may do more harm than good, which increases fuel consumption.

5, motorcycle fuel consumption is relatively complex, and the tire pressure, road conditions, wind resistance, shifting habit, come on, the state of the engine has a lot of relationship, such as light from speed to judge a motorcycle fuel consumption is a little biased, and motorcycle itself how much oil can consume, in general, there is no need to hold the heart, unless your car fuel consumption than with the car fuel consumption by 50%, otherwise generally don't have to care about it.
