Best injector cleaner for petrol and diesel engines

Fuel injectors’ function

Once the automobile industry kissed carburetors goodbye, it searched far and wide for the next compatible replacement. After decades of development, the electronic fuel injector has become the mainstay in both domestic and international vehicles. Before the gasoline or diesel undergoes combustion, it is the fuel injector’s job to atomize the fuel through a pressurized chamber which ignites the burning process. The spray should be able to pass through a narrow nozzle unobstructed for an efficient burn, hence maximizing fuel consumption. Fuel injectors uncluttered with dirt and debris also produce cleaner emissions which abide by the emissions law.
