What is the reason for the Xin Da Du EFI fault light to illuminate three times?

[King]

Xin Da Du EFI fault light illuminating three times indicates an electronic control fault in the engine. Introduction to automobile engines: The automobile engine is the device that provides power for the car, serving as the heart of the vehicle, determining its power, economy, stability, and environmental performance. Depending on the power source, automobile engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others. Common gasoline and diesel engines are both reciprocating piston internal combustion engines, converting the chemical energy of fuel into the mechanical energy of piston movement and outputting power externally. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have low manufacturing costs. Diesel engines have a high compression ratio, high thermal efficiency, and better economic and emission performance than gasoline engines. Maintenance of automobile engines: Maintain good ventilation in the crankcase. Most gasoline engines today are equipped with a PCV valve, but contaminants from blow-by gases can deposit around the PCV valve, potentially clogging it. Therefore, it is necessary to regularly clean the contaminants around the PCV valve. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. To avoid faults, the oil should be changed periodically based on usage conditions, and the oil level should be kept moderate. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, nitrogen oxides, and other substances from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Therefore, the crankcase should be cleaned regularly to maintain the cleanliness inside the engine.
