The fuel injectors in your Mercedes-Benz vehicle deliver an optimal amount of fuel to the engine. They do this via valves that direct fuel into the engine's combustion chamber, where that gas mixes with oxygen. Most vehicles feature at least one fuel injector in each cylinder, and their function is simple. The fuel pump draws the gas out of the fuel tank and through fuel lines to the injectors. An engine control unit, or ECU, then determines the proper time for the injectors to spray fuel through the nozzles into the combustion chamber.

Genuine OEM Fuel Injectors Perform Best

Even the best fuel injectors can begin to fail, though. They can clog, leading to problematic leaks. Another sign of trouble is If your engine starts misfiring, stalling, or idling rough. Finally, a failed emissions test or worsening fuel mileage could be due to a faulty fuel injector. You should inspect your injectors on a regular basis to ensure that they're working right.
