What Happens When Speed and Gear Don't Match?
1 Answers
If the speed is relatively high while the gear is low, the car is prone to phenomena such as sluggish acceleration, unresponsive throttle, and jerking. Conversely, if the speed is low while the gear is high, the car is more likely to stall or vibrate during driving. In actual driving, prolonged use of gears that don't match the speed can increase wear between the transmission gears, leading to larger gear meshing gaps, thereby reducing the transmission's lifespan. Speed ranges corresponding to each gear in a manual transmission: First Gear: The starting gear, used when the car moves from a standstill or climbs steep slopes, typically at speeds around 10 km/h. Second Gear: The driving gear. Used as a transitional gear for acceleration after starting or for low-speed forward movement, typically at speeds around 20 km/h. Third Gear: The acceleration gear. From this gear onwards, you can coordinate with the throttle to accelerate, increasing the car's speed to a certain extent. This gear is commonly used in urban driving at speeds between 20-40 km/h. Fourth Gear: The medium-high-speed driving gear. This is generally the highest gear used on city roads except for elevated sections, typically maintained at speeds around 60-70 km/h depending on the vehicle. Fifth Gear: The high-speed gear. Used only on elevated roads, highways, etc., generally at speeds of 80 km/h or above.
