The first point is the temperature, in the low temperature environment whether your car is burning oil or electricity, you will find that in the winter their endurance will become shorter, under normal circumstances, the winter engine thermal efficiency decreases, fuel motorcycle fuel consumption in the winter will be 10% to 15% higher than the summer.

In the winter of the year, the air density is relatively large, the driver will wear more and more thick clothes, some motorcycle friends will also install windshields, windshields and other cold accessories, so at the same speed, the motorcycle to overcome greater wind resistance and more load, it needs to consume more fuel.

The second point is the speed of the engine, I believe that in the small partners riding motorcycles in winter, the proportion of using scooters to commute can account for 70% or higher, due to the advantages of the model, the windshield effect of the scooter on the driver's legs is far better than the straddle model, and the scooter is also more convenient to install a variety of cold equipment, then there must be many small partners wondering, Why the same displacement, scooter fuel consumption will be so much higher than the car?

Indeed, in the case of the same displacement, the car will not only be better than the pedal in terms of fuel economy, but even the maximum power of the engine will be stronger than the scooter!

At present, there are two main heat dissipation methods of scooters, one is the forced air cooling heat dissipation on the small displacement pedal, and the other is water cooling heat dissipation, although the car is also using the same heat dissipation method, but the installation position of the engine is under the fuel tank, which is the highest heat dissipation efficiency of the vehicle.

The scooter engine is basically hidden under the bucket, the active heat dissipation efficiency of this position is extremely low, so the horsepower of the scooter is basically not pressed too hard, even the Yamaha TMAX, known as the king of sheep, has a displacement of 560CC, but the overall data of the engine is not much different from the domestic 500 level models.

It can be said that the fuel consumption of the scooter is higher than that of the transmission, due to the use of CVT continuously variable speed, so the scooter wants to speed up or maintain at a higher speed, it must keep the engine speed at the corresponding high, basically the scooter starts at about 2500 to 3000 RPM, straddle models at this speed can be used to cruise, When you want to get enough acceleration, the speed of the scooter engine must be maintained at more than 5,000.

The car is completely different, the idle speed of the straddle model is basically within 2000 RPM, and the large-displacement model can start even if it is hung in the 1 gear without refueling, so no matter what kind of working conditions, the car has a lower engine speed, and a higher transmission efficiency, even the bending beam car without the clutch, is also very fuel efficient.

Third point, oil, different grades of oil for fuel consumption is also there is a considerable impact, take the motorcycle usage of the highest 10W40 oil example, where W represents winter, the smaller the number in front of the oil in the low temperature environment is higher mobility, so the north of the motorcycle in the winter, you can change to a smaller than 10 grade of oil.

The number after W represents the viscosity of the oil, under normal circumstances, it is not recommended to replace the oil viscosity specified by the original factory, because the high-viscosity oil has better sealing, but it will also bring greater resistance to the engine interior, resulting in an increase in fuel consumption.

The most important thing is that the oil is not added as much as possible, it must be operated in accordance with the standard, and when you find that the above factors are excluded, the fuel consumption is still high, then you have to check the spark plug and air filter, whether it has not been replaced for a long time!
