What to Do If Gasoline Car Accidentally Adds Some Diesel?

[DelRuby]

If a gasoline car accidentally adds some diesel, do not start the engine to avoid diesel entering the fuel system. Tow the car to a 4S shop or repair shop to drain the diesel completely and then refill with gasoline. Diesel entering a gasoline engine will start burning violently before the spark plug ignites, causing abnormal pressure in the combustion chamber and leading to knocking. Diesel engines use compression ignition, which does not require spark plugs to ignite. The compressed air raises the temperature to the diesel's ignition point, and then the injected diesel combusts on its own. The fuel injector pressure in gasoline engines is much lower compared to diesel engines. When diesel is added to a gasoline engine, it cannot be fully atomized, resulting in incomplete combustion. This can cause the engine to feel weak, unresponsive to throttle input, and increase carbon deposits and clog the fuel injectors.
