What are the symptoms of a faulty diesel injector?

[RhettLee]

Diesel engine injector damage can cause noticeable power loss, black smoke from the exhaust pipe, increased engine noise, and sometimes a distinct "click, click, click" sound from the engine. The injector is a crucial component of diesel internal combustion engines, and its atomization level determines fuel consumption and engine power output. Good injector atomization ensures that vehicle fuel is fully converted into kinetic energy, maximizing power output. Here are 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 injector, plunger, and other fuel system components, so always purchase filters from reputable manufacturers and avoid cheap, inferior products.
