What is the relationship between car gears and speed?
1 Answers
The relationship between car gears and speed is as follows: 1. When the speed reaches 15 km/h, you can shift to 2nd gear; 2. When the speed reaches 25 km/h, you can shift to 3rd gear; 3. When the speed reaches 35 km/h, you can shift to 4th gear; 4. When the speed reaches 45 km/h, you can shift to 5th gear. When downshifting, follow the principle of deceleration first and then downshifting, and you can skip gears. When the speed matches the gear, the car's performance is at its best, and the thermal efficiency of the fuel is the highest. If the speed does not match the gear, such as high speed with low gear or low speed with high gear, it will not only increase fuel consumption but also cause damage to the engine and transmission, leading to irreversible harm to the vehicle. Therefore, it is essential to maintain the matching of gears and speed while driving.
