Fuel injection systems are nothing new and have been around since the 1950's first being developed for aircraft which had problems using carburetors in flight maneuvers. There are two kinds of injection systems both deliver gasoline and diesel fuels, mechanical and electronic, both use injectors and fuel pumps. Mechanical fuel injection is used on older engines and has been replaced by the newer electronic systems which are more easily controlled. Today's fuel injection systems are highly regulated and monitored to achieve the best performance and efficiency.
Fuel Injection Systems
The fuel injection delivery system starts in the gas tank where the fuel is stored. A pump inside the tank delivers the fuel to the injection rail or a secondary pump depending on the type of system. A PCM is used to control the system using various sensors such as oxygen, MAP (manifold absolute pressure) and MAF (mass air flow). A fuel filter is used to remove dirt and other contaminates which can hinder the operation and efficiency of the system.
