What is the Engine Start-Stop Technology Called?

Engine automatic start-stop technology is a system that can automatically control engine shutdown and ignition, known in English as STOP&START, abbreviated as STT. Below is an introduction to the engine start-stop technology: Function of the Technology: Engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Working Principle: When the vehicle stops due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops.
The technology I usually use while driving is called the Auto Start-Stop System. Simply put, it automatically turns off the engine when the car is stationary to save fuel and reduce emissions. I drive a hybrid vehicle, and it’s incredibly quiet when stopping at red lights—not only does it save fuel, but it also reduces environmental pollution. The principle is that the onboard computer detects when the vehicle is stationary and intermittently shuts off the engine, restarting it when accelerating. This feature is especially suitable for congested urban roads. However, it’s important to note that the system relies on a high-quality start-stop battery, and long-term use requires regular maintenance; otherwise, delayed starts may occur. Additionally, some people find the frequent restarts annoying at first, but once they get used to it, they come to appreciate the quietness. Overall, this is a standard feature in modern cars that helps us save a significant amount on fuel costs annually while also reducing the impact of exhaust emissions on the climate. It’s highly worth promoting, especially in big cities where frequent stops and starts make its effects even more noticeable.
After years of repairing cars, I often encounter this technology, commonly referred to as the Start-Stop function or Stop-Start system. It reduces fuel consumption by shutting off the engine when the vehicle is temporarily stopped (e.g., at traffic lights). From a mechanical perspective, the core involves the coordinated operation of sensors and the starter, but frequent start-stops place high demands on the starting components, requiring durable engine oil and regular battery life checks. Customers often complain about more frequent malfunctions in winter, as the low temperature requires the engine to preheat, causing the system to deactivate. I recommend that novice car owners regularly visit a shop for circuit inspections to avoid unexpected failures. Overall, this technology reduces road emissions and represents progress in automotive engineering, but it comes with slightly higher maintenance costs. When choosing a car, it's best to opt for original factory parts to ensure stability.
