What Is a Fuel Injector?
Fuel injectors deliver precise fuel to your engine. A Cranbourne West specialist explains how they work and fail.
What it is & what it does
Fuel injectors spray a precise, finely-atomised amount of fuel into each cylinder (or intake), timed exactly by the engine computer. Modern direct-injection injectors work at very high pressure.
Clean, correctly-working injectors are essential for smooth running, power and economy.
Signs of trouble & how we help
Faulty or clogged injectors cause misfires, rough idle, hard starting, power loss, smoke or poor economy. Diesels especially can suffer injector wear. Some respond to cleaning; others need replacing.
We diagnose injector faults with live data and testing, and advise clean vs replace honestly.
