Modern vehicle solutions such as Mercedes Benz 450SLC use fuel injection system instead of carburetor. This system is of two types - the mechanical and electronic fuel injections. Both types possess fuel injectors which directly spray fuel into the combustion chamber. Fuel injector is an indispensable electromechanical device comprised of solenoid, spray tip, plunger, fuel filter and valve spring. It is located in the intake cavity or throttle body in throttle body injection systems and at the mouth of intake port for multi-point injections.

Like all other fuel injectors, a Mercedes Benz 450SLC fuel injector is basically a fuel-dispensing nozzle specially engineered to deliver correct amount of fuel to every cylinder harmoniously with the throttle body movements and engine speed. And by metering the fuel, cylinders are charged with equal strength and quality that results to smooth and even operation. Compared to carburetor that’s doing several tasks all at the same time, fuel injection system’s injector do the specific job, without compromising efficient fuel delivery and all other vital tasks.
