What gear should be engaged for stationary engine revving?
2 Answers
For automatic transmission vehicles, stationary engine revving should be performed in N gear, which is the neutral gear. Reasons for engaging N gear: In this gear position, pressing the accelerator will not deliver power to the wheels, preventing vehicle movement, thus allowing stationary engine revving. Detailed operation steps are as follows: After depressing the brake pedal, press the one-touch start button, wait for the dashboard to illuminate indicating vehicle startup, then shift the automatic transmission lever to N position, finally depress the accelerator to perform stationary engine revving. Precautions: During stationary engine revving, the load on internal engine components increases instantaneously. The radiator's cooling efficiency significantly decreases without incoming cold air, potentially leading to severe consequences like burning out the connecting rod bearings (big/small end bearings). Additionally, this practice adversely affects belts and gears.
As a seasoned driver with years of experience, I can tell you that when revving the engine to enjoy the sound, you must always be in neutral. For manual transmissions, shift to the N position, and for automatic transmissions, select N or P for safety. The reason is simple: if you're in drive or reverse and the clutch isn't fully depressed or the brake is released, the car could suddenly lurch forward, causing a scare at best or an accident at worst. I've seen someone do this in a parking lot, and the car ended up crashing into a flower bed, costing thousands in repairs. Additionally, revving the engine in drive for extended periods puts extra strain on the transmission, with automatic transmissions' torque converters prone to overheating and wear, shortening component life. When done correctly, the engine sound is purer, but remember not to overdo it—it wastes fuel and creates noise pollution. However, using this method to warm up the engine during maintenance is a good practice, keeping it to around 30 seconds. Always prioritize safety: double-check the gear position, engage the handbrake, and develop good driving habits to protect both your vehicle and yourself.
