Today, automatic transmission cars are already the darlings of the auto market. Many families now buy automatic transmission cars. Although automatic transmission cars look good and drive well, compared with manual transmission cars, there is less driving pleasure. This is why many The reason why old drivers like to manually block cars, and in manual cars, many people will hear the word downshift to refuel, but for some novice drivers, they do n’t know what it means. What does downshift refueling mean? What's the use? Let's take a look at how the article says it.
What is the meaning of downshift refueling in a manual car?
Most people are simply decelerating and downshifting. The step is to step down the brakes to reduce the speed of the car. Wait until the car is idling before stepping on the clutch. In the operation of the old driver, there is another method is to downshift to refuel. As the name implies, downshifting is to “make up a foot” when downshifting, in order to eliminate the speed difference between the engine and the transmission. Synchronize the engine speed with the gear as much as possible, so you can reduce the frustration when downshifting. If the vehicle speed and gear are not matched, the gears meshing during shifting will cause vibration and frustration. At this time, the old driver generally chooses to press the accelerator slightly to replenish the fuel and increase the engine speed. Try to match the speed of the vehicle as much as possible to reduce the frustration to a certain extent. It should be noted that when refueling when downshifting, you cannot make up too much, that is, you cannot step on the accelerator deeply. Too much fuel will make the car move forward too much, and it will give people the feeling of moving forward. Correspondingly, if the refueling is too little, the effect is not obvious, and the car will still feel frustrated.
Although the manual transmission car is rich in driving experience, it also tests the driving skills of the owner. Especially during the upshift and downshift, you need to master a lot of downshift refueling methods to make the car drive smoothly and quickly. It is worth mentioning that there are many ways to open the manual downshift refueling. In addition to the conventional refueling method, there are advance fueling method and two-foot clutch fueling method. Here we focus on the two-foot clutch fueling method. The operation is also very simple. First, step on the clutch loose throttle and hang in neutral, then step on the clutch with the right foot while emptying the clutch, then step on the clutch loose throttle and hang in the low gear, such as 1 or 2. The next step is to loosen the clutch and step on the accelerator.
In short, one of four actions is: stepping on the clutch and neutral gear-loose clutch and empty fuel-stepping on the clutch and loose throttle hanging on the low gear-loose clutch and stepping on the accelerator to move forward. During this period, you need to step on and off the clutch twice and step on the accelerator twice. This is the two-foot clutch refueling method in downshift refueling. This method is the most widely used and can be mastered by car owners.
Downshift refueling operation method
1. In operation, the left foot clutch pedal must be depressed to shift or remove gears, otherwise it is easy to hit teeth and damage the gearbox;
2. Minimize the semi-clutch state (that is, the state where the clutch is not fully raised), otherwise it will affect the clutch life. A long-term half-clutch will burn out the clutch. The half-clutch is only used at the moment of high torque starting or when the power requirements change particularly quickly. Of course, this is the advantage and flexibility of our manual transmission. We will talk more about it later.
3. Lift the clutch. If the difference between your vehicle speed and the engine speed is large, you need to lift the clutch slowly, so that the engine speed can be brought up through the clutch to reduce the impact on the engine and the sense of frustration. Of course, this can also be done by refueling or slowing down.
