Maintains a clean fuel system, restores power, restores performance, facilitates engine cold starts and smoother operation, and prevents carbon deposits. Start-stop is a system that turns off the engine when the vehicle is stationary to reduce fuel consumption and emissions. When the brake is released or the clutch is engaged and the driver is ready to move again, the engine starts. A conventional vehicle without automatic start is expected to stop up to 50,000 start-stop events. However, with the automatic start of the stop, which is activated every time the car stops, this figure rises sharply. A consequence of this is stop-start technology, which is more prone to accumulation of deposits. After the fuel intake system is working, the driver of the vehicle with the engine start / stop will experience; loss of power, handling problems and exhaust emissions.
