Car of load of high speed road does not run to cross a car to do not have so absolutely, if Zhen Biao rises, the 110km/h on the 120km/h on small-sized passenger car, large passenger car also is not to had not seen. Nevertheless the car meets the guest to control speed on high speed really, also be in commonly 90km/h level.
OK and affirmative is, although majority passenger car is used, is derv engine, can bring about quicken ability and top speed to do not have gasoline engine tall, but speed per hour is to be able to exceed 120km/h, it is so inside speed limits of the regulation, the passenger car wants to had run the car is nonexistent technical obstacle.
If driver of average nevertheless bus is not need otherwise can choose so dry, the car is put in the view of economic speed per hour when high speed road drives, the passenger car because the car is heavier, oily cost is high, want to pay attention to control speed more necessarily.
We know wind resistance is air a kind of when form to the car in advancement retrorse active force, its computational formula is: V2(kg) of · of Cw of · of Fw=1/16 · A.
Understanding comes over even if: Wind resistance becomes square direct ratio to concern with speed, rate increases 1 times, the obstruction that the car gets can increase 3 times. So if speed is too fast, can increase wind block, oily to reducing bad news is adverse.
Divide in addition, some moment are not bus driver does not want to carry fast, still be to be not carried likely. Because some passengers opened car window,this is likely very, the passenger car because type of build or figure is great, if car window opens the wind force more of infuse, the effect that wind block brings will be more more apparent than the car.
And because passenger car heart is high, when circumstance of or so window is abhorrent, right-and-left fill can differ somewhat into the quantity, when low speed drives not bad, if want to play high speed, can go against the driver control to car.
Although unapt say not to accuse a car, but can add fatigue touch. Anyhow, car of load of high speed road does not run to pass a car, both neither is a design speed per hour also is not a driver not quite those who leave is slow. However oily bad news, drop fatigue move the result that these real factors affect.
