“Out with the old; in with the new.” For the majority of the time that internal combustion engines have been around, carburetors were the mechanisms used in the delivery of fuel to the engine. It performed well enough at first, but as the automobile became more and more complex, carburetors simply could not keep pace with the changes that were quickly beginning to occur under the hood. The manner in which carburetors were functioning simply became rather inefficient with time and technology, and so a new type of fuel delivery system was introduced: the fuel injector.

These injectors were relatively simple replacements for carburetors early on, but were eventually phased out and replaced with multi-port fuel injection, the type of system present in all vehicles produced today. Your Volvo 740 fuel injector is the electric valve that facilitates the movement of fuel from the fuel pump to the engine. It’s capable of opening many times per second, and the amount of fuel that the fuel injector supplies to the engine is dependent on just how long it stays open.

The fuel is made into a very fine mist in order to allow the engine to burn it more efficiently, since the fuel is converted into the simplest form possible. Multiple sensors ensure that the fuel delivered by your Volvo 740 fuel injector is the right amount, and at the right time. The system is very advanced and certainly a far cry from the carburetor systems of old, and as such these new systems require a large degree of maintenance and care to ensure a constant level of acceptable performance.We’ve got Volvo 740 fuel injectors here if you decide it’s time to replace your old one.
