How to Understand High Gears and Low Gears?
1 Answers
Low gears generally refer to 1st and 2nd gears, while high gears usually refer to gears above 3rd. Due to the higher torque of low gears, they can overcome greater resistance, which is why vehicles typically start and climb steep slopes in low gears. High gears, with their higher rotational speeds, allow the wheels to rotate faster, making them suitable for high-speed driving when shifting to higher gears. Here are some related explanations: 1. The Hazards of High Gear at Low RPM: Driving in high gear at low speeds can easily lead to carbon buildup inside the engine. When carbon deposits accumulate to a certain extent, they can cause issues such as difficulty starting the vehicle, increased fuel consumption, reduced engine power, and sluggish acceleration. The engine's computer has a self-learning function and will remember this driving habit, leading to persistent lack of power in the future. 2. The Hazards of Low Gear at High RPM: Driving in low gear at high RPM means the engine has to rotate more times for the same distance. The more the engine rotates, the more wear and tear it experiences, and more gasoline is consumed. For example, driving the same distance in 2nd gear versus 5th gear will require the engine to rotate at least twice as many times in 2nd gear.
