Duramax injectors play a very important role in your diesel vehicle. They inject fuel into the engine at the right time to ensure optimal efficiency. Older vehicle had carburetors that mixed the air and fuel before it was delivered to the engine. In the 1990s, fuel injectors replaced carburetors, and have since evolved into highly efficient systems in today’s vehicles. Engines that are fuel injected provide a better power output compared to carbureted engines.
So, how do the Duramax injectors? They are electronically controlled valves that deliver fuel to the engine. The injectors are found in the engine’s intake manifold. The fuel pump supplies the pressurized fuel to the injector through the fuel rails.
Duramax injectors spray the fuel into the engine through a nozzle that opens and closes through a plunger. The plunger movement is controlled by an electromagnet. The nozzle atomizes the fuel - sprays the fuel into the chamber as a fine mist which is more volatile to combustion. The amount of fuel injected into the engine is determined by the time the nozzle stays open, which is controlled by the Engine Control Unit (ECU).
Oftentimes, fuel injectors can get clogged with debris after being in use for a few years. The fuel filter is the component that separates the debris from the fuel. With time, the filter itself may get clogged, something that allows impure fuel to flow into the injector. Problems with fuel injectors can also arise because of a fault in the electromagnetic mechanism or due to fuel leaks in the injector.
There are various ways that you can know that your Duramax injectors are faulty. Some of these include gasoline leaks, rough engine idling, poor fuel economy and surging/misfiring. You need to take action immediately when you start noticing these symptoms.
