Is it necessary to clean the fuel injectors? How often should they be cleaned?

It is very necessary, and the cleaning cycle for fuel injectors is every 2 years or 50,000 kilometers. Below is relevant information about fuel injectors: 1. Definition: A fuel injector is essentially a normally closed valve (a normally closed valve remains shut when there is no control signal input, whereas a normally open valve stays open without a control signal). The opening and closing of the valve are controlled by the up-and-down movement of a needle valve. When the ECU issues a fuel injection command, the voltage signal causes current to flow through the coil inside the injector, generating a magnetic field that lifts the needle valve, opening the valve to allow fuel to spray out through the injector nozzle. 2. Impact of carbon deposits: As one of the key components of an electronic fuel injection engine, the performance of the fuel injector significantly affects the engine's overall performance. Clogged fuel injectors can severely impair vehicle performance. The blockage occurs due to carbon deposits accumulating on the injectors or impurities in the fuel obstructing the injector's pathways. After a period of driving, certain deposits will form in the fuel system.
Cleaning fuel injectors is quite necessary as they are responsible for precisely spraying gasoline into the engine. Once carbon deposits accumulate excessively, uneven fuel injection may occur, potentially causing engine shaking, unstable idling, or even a surge in fuel consumption. From my experience with many car owners, when vehicles exceed five years in age or around 30,000 kilometers in mileage, symptoms like the engine warning light illuminating or sluggish acceleration often trace back to clogged fuel injectors upon inspection. It's recommended to clean them every 20,000 to 30,000 kilometers or every one and a half to two years, especially for those frequently driving in urban traffic congestion where incomplete fuel combustion accelerates carbon buildup. For minor cases, you can conveniently and affordably use fuel injector cleaner additives in the gas tank. For more severe cases, professional shops offer thorough cleaning services costing around a hundred bucks, preventing minor issues from escalating.
