What are the symptoms of a faulty diesel fuel injector?
2 Answers
When the fuel injector of a diesel engine is damaged, the vehicle will experience a noticeable lack of power, black smoke from the exhaust pipe, increased engine noise, and sometimes a distinct "click, click, click" crisp noise from the engine can be heard. The fuel injector is a crucial component of a diesel internal combustion engine, and the degree of injector atomization determines fuel consumption and the engine's power output. Good injector atomization ensures that the vehicle's fuel is fully converted into kinetic energy, maximizing power output. Here are some methods to avoid injector damage: 1. Refueling: Always refuel at reputable, large gas stations. 2. Maintenance: Replace the diesel filter promptly. The diesel filter is the last line of defense for protecting the fuel injector, plunger, and other fuel system components, so always purchase filters from reputable manufacturers and avoid cheap, low-quality filters.
Recently, while commuting in my diesel car, I encountered a faulty fuel injector issue with very noticeable symptoms: the car shook violently when starting, rocking like a massage chair; acceleration felt sluggish, requiring prolonged throttle input to gain speed; cold starts in winter were even more troublesome, taking two or three attempts to ignite, and sometimes idling at red lights would cause unsettling wobbles, giving me a scare. Fuel consumption also surged, with a full tank covering dozens of kilometers less than usual. The most distressing part was the black smoke from the exhaust—looking in the rearview mirror, thick plumes of black smoke billowed out, making environmental friendliness out of the question. If left unaddressed, the engine warning light might eventually come on. Later, I had a friend fix it by replacing the fuel injector, and looking back, handling it earlier would have saved both hassle and money. Now, the car runs smoothly and comfortably again.
