Why do the double-ring aristocrats consume high fuel?

1, the engine air intake is insufficient, and there is a lot of carbon deposition in the throttle and air intake.

2. When the tire pressure is too low or the tread is seriously worn, the contact area between the tire and the road surface becomes larger, the friction force increases, the rolling resistance increases, and the fuel consumption naturally increases.

The high fuel consumption of the car is also the problem of the car itself, and most of it is also caused by the driver's driving habits. Our frequent starting and stopping will also cause high fuel consumption.
