The Fuel Injector in Chevrolet HHR vehicles provides the essential task of spraying fuel directly into the engine cylinders so that there can be an enhanced proportionate mix of air and fuel for combustion. It is electronically controlled by the Engine Control Module (ECM) with the help of which amount and timing of the fuel injection depend on the load of the engine. Chevrolet HHR models employ returnless fuel injection arrangement that eliminates the requirement for a return line for the fuel supply system. This eliminates several fuel lines and improves reliability of the BMEP compared to prior art designs. Usually, the fuel injectors of HHR are durable but they might develop defects and start to clog or even leak that impacts the performance of the engine and the overall economy of the vehicle. Minor and routine check up together with replacement of faulty injectors is a good way to avoid more complications to your engine.
