After driving for so long, I don’t know if my friends have noticedbrakeActually higher than the throttle, so why on earth?Obviously know thesecarCold knowledge, but you don't understand. This is the difference between you and Mingming... don't come and take a look at these car knowledge!
1. The brake is higher than the throttle
In fact, the brake throttle is not at the same height. Under normal circumstances, the brake is higher than the throttle. Except for some high-performance cars (sports cars), in order to facilitate the toe action when braking, the brake will be as high as the accelerator. From the perspective of ergonomics, the brake pedal and the accelerator pedal must have a certain degree of recognition. When stepping on the brake, prevent accidentally stepping on the accelerator to ensure the safety of the people in the car.Brake pedalThe stroke is larger than the accelerator stroke. The accelerator pedal will be placed in the comfort range when designing, and the brake pedal will be about 20mm higher than the accelerator pedal, which feels a little uncomfortable, which serves as a reminder to the driver to prevent misstepping. accelerator.
2,airbagThe actual life is shorter than the whole vehicle
Theoretically, the design life of the car's airbag is the same as the service life of the entire vehicle. However, due to the lack of design standards, the actual life of airbags is not that long. Although there is no clear shelf life, the quality of airbags cannot be guaranteed even if they do not detonate after 8 to 10 years of use. The vehicle will have an OBD self-inspection process during the start-up process, including airbag system inspection. After every 10,000 to 20,000 kilometers, the vehicle should go to the 4S store to check the airbags and their accessories. You can also ask the 4S store to inspect the airbags during vehicle maintenance at the 4S shop.
3. The glass water turns blue to remind people of its toxicity
I believe that many people have never known why the glass water is blue. In fact, incar windscreenIn water, many functions are accomplished by adding chemical additives. Therefore, glass water is toxic. The liquid turns blue to remind people of its toxicity. At the same time, in order to distinguish it from other searched liquids, avoid adding errors.
4. It is really impossible to refuel in a thunderstorm
When refueling under thunderstorm conditions, the fuel gun can easily introduce stray current into the cartank, Resulting in intensified movement of unstable gasoline molecules, leading to fires, explosions and other accidents. In gas stations, the fuel vapor concentration is significantly higher than other places. If the refueling operation continues, the fuel vapor is easily struck by lightning, causing the vehicle and fuel tank to explode. Therefore, don't go to the gas station to refuel during a thunderstorm!
