Therefore, under the premise of ensuring the normal operation of the car, the throttle amplitude should be appropriately reduced.

Practical knowledge of automobiles The wear of the clutch disc and clutch pressure plate, the spark plug has been used for too long, and the phenomenon of increased fuel consumption will also occur, so it should also be replaced regularly.

1. Anti-glare rearview mirrors are not only equipped in medium and high-end models, but for most models, in-car rearview mirrors have manual anti-glare function.

2. Light refueling, light braking, early braking. Braking suddenly while driving, starting suddenly, and stepping on the accelerator are all fuel-saving taboos. The fuel-saving test shows that stepping on the accelerator costs 2 to 3 times more fuel than driving at medium speed. Therefore, under the premise of ensuring the normal operation of the car, the throttle amplitude should be appropriately reduced.

3. Car structure: A car usually consists of four parts: engine, gearbox, axle and body. Among them, the engine is the heart of the car and is mainly used to drive the vehicle.

We should keep in mind the position of the fuel tank cap of our vehicle and park the car in the corresponding position when refueling, otherwise the refueling pipe may not be long enough.

6, 80km/h cruising, the fuel consumption used to overcome wind resistance should reach 60%; if the speed can be driven to 200km/h when driving, the air resistance accounts for 85% of all resistance of the car. This is an approximate value, and different models are also very different, so when buying a car, don't look down on the exterior design.
