What is the high fuel consumption of Mercedes-Benz E-Class parking idle speed?

It is not that only Mercedes-Benz E-Class has high idle fuel consumption, but basically all models do. When idling, the engine speed is always kept at a very low speed, the outside air can't get good contact with the gasoline in the engine, and the gasoline can't be fully burned, so the fuel consumption is relatively high. Idling for a long time is easy to form carbon deposits in the cylinder, so try not to idle for a long time. In daily driving, carbon deposits in the fuel system and engine should be cleaned regularly, spark plugs should be replaced regularly, tire pressure and four-wheel alignment should be checked, a good driving style should be developed, and the engine should work at a constant speed. For old cars, attention should be paid to adjusting the steering wheel and tires. These maintenance and driving tips can reduce the fuel consumption of cars and achieve the purpose of saving fuel.
