For novice drivers with little driving experience, automatic cars are undoubtedly the best choice. The driver only needs to control the throttle and brakes, which is much more convenient than manually operated cars. But when we usually drive an automatic car, we obviously desperately step on the accelerator, but the speed cannot be improved, is it the car that has failed? In fact, it is not, if you will use this function, the automatic car can speed up quickly.
The most gear we usually use when driving automatic cars is D gear, and many car owners are directly D gears around the world. Although D gear is indeed very practical, but we hang up D gear when overtaking, the car is relatively slow to react. If you want to overtake quickly, you can put the gear into S gear.
As the sports gear on the automatic transmission car, S gear will be much more powerful than the low gear, and we can understand that it is an upgraded version of D gear. When we are hooked up in S gear, the car gearbox can change gears freely, and ensure that the engine continues to produce power and acceleration steadily. Therefore, when we want to overtake or climb a hill, we can hang up the S gear, which can make the car get enough power in a short period of time.
However, although S block is good, there are also many disadvantages. If we frequently use S gear, it will not only increase the gearbox load and aggravate engine wear, but also lead to increased fuel consumption and reduced riding comfort of the car. And S gear is not suitable for all situations, when we run high speed can not use S gear. Although using S gear will make the car run faster, the car will be noisier under the S gear, which will affect our driving safety. In addition, running at high speed with S gear is more fuel-intensive, maybe people run a high speed as long as a quarter of the oil, and you need more.
After talking about the problem of automatic car S gear, let's talk about the L and N gears of automatic cars. L gear is actually low speed gear (L stands for Low), but also a climbing gear, its role is to limit the maximum gear of the automatic transmission. When we hook up in L gear the car will only switch between 1st or 2nd gear. In this case, the car will obtain a relatively strong torque, thus ensuring the sustainability of the car's power.
When we drive uphill, as long as we are hung up the L gear, the car engine will get a relatively large torque, even if the car pulls a lot of goods can easily climb the hill. When we drive down a steep slope, as long as we are hooked into L gear, the car will be limited to low gear, at this time we can make full use of the engine brake to control the speed, so as to avoid long-term braking and causing brake failure.
N gear as a neutral gear on the car, when the car needs to be temporarily stopped, we can put the gear into N gear. When we are driving and waiting for a red light or when the car is malfunctioning and needs to be towed, we can all put the gear into N gear. Although N gear and P gear are the same as parking functions, N gear can play a role in alleviating the working pressure of automatic transmissions, which can better protect automatic transmissions, thereby increasing the service life of the car.
It can be seen that all gears on the car play a very important role, and everyone must make good use of it.
