If the car is left running and the key is taken away, it will not automatically shut off. Here is an introduction about engine shutdown: 1. Introduction: Also known as flameout. When the reactor is operating at a significant reaction rate, if the inlet temperature of the feed is lowered to reach the lower limit of the multiple-state region, the reaction rate will suddenly drop significantly, and the reaction will basically stop. 2. Definition: This phenomenon is called flameout. The corresponding inlet temperature is called the flameout point. It generally refers to car engine shutdown. 3. Precautions: Thoroughly clean the fuel system, including the fuel injectors, throttle body, fuel tank, etc. It may be caused by poor fuel quality with excessive gum and deposits, which can clog the fuel lines and hinder fuel supply.
