What are the effects of revving the engine in N gear on the car?

[HarperAnn]

N gear is the neutral gear. If the duration is short, there is no issue. However, if the engine speed is around 4,000 to 5,000 RPM, prolonged use will consume more fuel and may cause the engine to overheat, leading to boiling. Below is an introduction about using N gear: 1. Introduction: N gear is the neutral gear, which disconnects the input and output shafts of the transmission, cutting off power transmission. Both automatic and manual transmissions generally have a neutral gear. The only difference between P gear and N gear is that P gear has a locking mechanism. 2. Short-term use: N gear can be used for short-term parking. For example, when waiting at a red light, you can shift into N gear. It can also be used when parking briefly without turning off the engine, such as waiting for someone by the roadside. P gear is used when parking and turning off the engine to leave. Many car models have a safety design where the key cannot be removed unless the gear is shifted into P after turning off the engine. This design is to prevent the driver from forgetting to engage P gear, which could cause the car to roll. Therefore, P gear is used when turning off the engine to leave, while N gear is used for short-term parking.
