How is the matching between car gears and speed?
1 Answers
Car gear and speed matching involves starting in first gear, shifting to second gear at around 10 km/h, third gear at 20 km/h, fourth gear at 45 km/h, and fifth gear at 60 km/h. When the speed corresponds to the gear, the car's operating performance is at its best, and the thermal efficiency of the fuel is highest. If the speed does not match the gear, such as high speed with low gear or low speed with high gear, it not only increases fuel consumption but also causes damage to the engine and transmission, leading to irreversible harm to the vehicle. Therefore, it is essential to maintain the appropriate gear and speed matching while driving. Notes on gear shifting: For beginners, in addition to mastering the timing of gear shifting as quickly as possible, it is also necessary to learn the hand gestures for shifting. When shifting gears, keep the five fingers together, lightly grip the gear knob, and use the forearm to guide the hand in shifting. Be gentle and slow when shifting, avoiding excessive force to prevent shifting into the wrong gear. Always pause in neutral before shifting, and if you shift into the wrong gear, don’t panic—simply return to the original gear and shift again. Introduction to automatic transmission gears: Automatic transmission gears include P (Park), R (Reverse), N (Neutral), D (Drive), and B (Brake). P is for parking and is used for long-term parking, R is for reversing, N is neutral and used for short stops like at traffic lights, D is the automatic driving gear where the computer shifts gears automatically, and B is the braking gear.
