Gear shift lever classification

Manual gear shifting

For a manual transmission car, if you want to drive freely, the importance of the clutch cannot be ignored. When driving, except when you need to depress the clutch pedal when starting the car, shifting gears, and braking at low speeds, do not depress the clutch or put your foot on the clutch pedal at other times.

Correct operation when starting. The key points for operating the clutch pedal when starting are "first fast, second slow, and third linkage". That is, lift the pedal quickly when starting to lift; when the clutch is semi-linked (the sound of the engine changes at this time), the speed of pedal lifting is slightly slower; in the process of linkage to complete combination, slowly lift the pedal on the clutch While lifting the pedal, gradually depress the accelerator pedal according to the engine resistance to make the car start smoothly.

Correct operation when shifting gears. When changing gears while driving, the clutch pedal should be depressed and lifted quickly to avoid semi-linkage, otherwise it will accelerate clutch wear. In addition, pay attention to coordination with the throttle when operating. In order to make the gear shifting smooth and reduce the wear of the transmission shifting mechanism and clutch, it is recommended to use the "two-foot clutch shifting method". Although this method is more complicated to operate, it is a good way to save money while driving.

Proper use when braking. When driving a car, except for low-speed braking and parking where you need to depress the clutch pedal, try not to depress the clutch pedal when braking under other circumstances.

The control of manual transmission is relatively complicated, and there are some skills and tips. The key to pursuing power is to grasp the timing of shifting gears to make the car speed up effectively. Theoretically speaking, an engine generally accelerates most efficiently when it is close to its torque peak.

Automatic car gear shifting

The gear shifting of an automatic transmission car is controlled by a computer and is easy to control.

1. When driving on a straight road, generally use "D" gear. If you are driving on a crowded road in an urban area, shift to the 3rd gear position to obtain stronger power.

2. Master the left foot to assist in controlling the brakes. If you have to drive up a short slope before entering a parking space, you can control the accelerator with your right foot and apply the brake with your left foot to control the vehicle to move forward slowly to avoid rear-end collisions.

The gear selector of an automatic transmission is equivalent to the shift lever of a manual transmission. It generally has the following gears: P (park), R (reverse), N (neutral), D (forward), S (or 2, which is 2 Speed gear), L (or1, which is 1st speed gear). The correct use of these gears is especially important for people who drive automatic transmission vehicles. After starting a vehicle with an automatic transmission, if you want to maintain better acceleration performance, you can always maintain a larger accelerator opening, and the automatic transmission will Upshift to a higher gear when the vehicle speed is higher; if you want to drive smoothly, you can gently lift the accelerator pedal at the appropriate time, and the transmission will automatically upshift. Keeping the engine speed at a lower speed at the same vehicle speed can achieve better economy and a quiet driving feeling. At this time, if you lightly press the accelerator pedal to continue accelerating, the transmission will not immediately return to the original gear. This is an early upshift and delayed downshift function designed by the designer to prevent frequent gear changes. If you understand this truth, you can enjoy the driving pleasure brought by automatic transmission as much as you like.
