Correct Method for Automatic Transmission Start-Stop Function?

[TaliaMarie]

In automatic transmission vehicles, the start-stop system operates normally as soon as the engine is started. When the brake is pressed, the engine typically shuts off automatically within 1-2 seconds. Here are the drawbacks of frequently switching the start-stop system on and off: 1. Higher maintenance costs for the battery and starter: Frequent engine starts and stops can damage related components such as the starter and battery. 2. Poor user experience: Noise and vibration are more noticeable when the start-stop system activates. 3. Increased fuel consumption in traffic jams: During severe traffic congestion, the engine remains off for extended periods, causing the combustion chamber temperature to drop. Unburned hydrocarbons and paraffin can form carbon deposits on the cylinder walls. Poor fuel quality exacerbates this issue. Carbon deposits lead to higher fuel consumption and reduced power, counteracting the fuel-saving purpose of the start-stop function and instead increasing fuel usage.
