How to Determine if the Fuel Injector is Faulty?
1 Answers
Symptoms of a faulty fuel injector are as follows: 1. Engine vibration. When the fuel injector is damaged and fuel injection is obstructed, the engine may exhibit operational vibrations during operation. 2. Decreased power and increased fuel consumption. As the fuel injector deteriorates, the fuel injection volume and pressure cannot be guaranteed, leading to symptoms such as reduced vehicle power and increased fuel consumption. 3. Increased exhaust emissions pollution. Malfunctions in the engine fuel injector will inevitably affect the mixing and combustion of the combustible gas mixture, resulting in increased pollutant emissions from the vehicle exhaust. 4. Difficulty starting or even stalling. When the fuel injector is severely damaged, the vehicle may experience difficulty starting and even sudden stalling while driving. 5. Engine misfire. If the fuel injector of an individual cylinder is severely damaged, the engine is highly likely to experience misfiring, leading to severe engine vibrations. 6. Black smoke from the exhaust. As the fuel injector fails, the atomization of fuel and its mixture with air cannot be ensured, preventing complete combustion of the combustible gas mixture. This results in black smoke from the vehicle and increased engine carbon deposits.
