What are the disadvantages of low gear and high speed?
1 Answers
The hazards of low gear and high speed: 1. Wastes gasoline. 2. Fails to fully utilize the car's kinetic energy, causing the engine to run at high speed while the gearbox operates in low gear. Suddenly shifting a high-speed car into low gear will make the car's operation drive the engine, resulting in changes in sound, which is not advisable during operation. 3. Long-term use can cause a large amount of carbon buildup. The hazards of low speed and high gear: 1. Driving at high gear and low speed makes it difficult to utilize the engine's full power and may even damage the vehicle's powertrain. 2. When the engine operates in high gear and low speed, the engine output is weak, with low torque. Even if you press the accelerator hard, it lacks the power to speed up. As a result, a lot of fuel is consumed, but the engine runs very slowly, so it is not fuel-efficient. 3. Running for a long time in high gear and low speed keeps the engine working near the critical speed, often on the verge of stalling. The insufficient output force prevents the transmission from functioning properly, causing significant damage to the transmission. 4. Low-speed operation makes it difficult to achieve the engine's self-cleaning effect, leading to carbon buildup in the engine and fuel system, which can eventually cause faults in the engine and fuel system.
