2 Answers
Engine start-stop refers to a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving, such as waiting at a red light, and can restart the engine when the car needs to move forward again. The main function of the engine is to increase pressure and intake volume to achieve higher power output, making the car more powerful. Engine types can be categorized by their intake systems as: naturally aspirated, turbocharged, and by cylinder arrangement as: inline engines, V-type engines, W-type engines, and horizontally opposed engines.
I've driven various car models, and the engine start-stop technology refers to when you're waiting at a red light or temporarily parked, the engine automatically shuts off to save fuel and reduce emissions. When you need to move, stepping on the accelerator quickly restarts the engine. The entire process relies on sensors monitoring speed, brakes, and gear position to achieve fuel cut-off during stops, with electrical systems powered by the battery. Restarting involves the starter motor, ensuring a smooth and effortless operation without delay. In city driving with frequent starts and stops, it can reduce fuel consumption and CO2 emissions by over 10%. Data shows that an average car can save hundreds of dollars in annual fuel costs and also benefits urban air quality. However, it's essential to maintain the battery and starting system properly to avoid minor issues. Overall, the technology is mature and user-friendly.
