Is the Auto Start-Stop Function of the Engine Practical?

[OMary]

Auto start-stop function is useful. It can reduce unnecessary fuel consumption, lower emissions, and improve fuel economy. Here are some precautions when using the engine auto start-stop: Turn off start-stop in traffic jams: Repeated start-stop not only increases fuel consumption but also adds burden to the engine. Turn off start-stop on slopes: Although the auto start-stop time is very brief, the engine start-stop on slopes may lead to insufficient brake assistance. Turn off start-stop when using air conditioning: Since air conditioning requires significant power consumption, the vehicle's electrical system may not provide enough power to run the air conditioning when the engine is off, causing discomfort to passengers. Turn off start-stop when wading: When the vehicle is wading, the speed is relatively low. If the brake is pressed at this time, the auto start-stop will engage, and the engine will stop working. The exhaust pipe will then be under negative atmospheric pressure, causing water to flow into the exhaust pipe. Restarting the engine under such conditions can severely damage it.
