A typical fuel injector contains an electronically manipulated valve that supplies pressurized fuel into the different systems of the car by means of a fuel pump. The same is true with GM Fuel Injectors. A closer look inside the GM fuel injector reveals a nozzle that atomizes the fuel for easier fuel combustion. The power flow that passes through the injector coil produces a magnetic field that propels the armature to move upward. As a result, fuel pressure is built causing the fuel to move and flow out of the injector nozzle.

are installed at the intake manifold to allow direct fuel spray into the intake valves. These valves work closely with fuel rails, which gives off pressurized fuel to all injection units.

are categorized according to injection point---single-point and multi-point. Single-point injectors are injected through one nozzle, while the multi-point ones use utilize each cylinder's injector in the inlet manifold.

The use of fuel injection system may have worked wonders for GM in the car maker's efforts to cut down its vehicles' fuel consumption and increase performance. Still, petrol prices are still soaring and exhaust emission standards have become more stringent. To minimize the adverse effects of these developments, an aftermarket fuel economizer has been created?--the

One of the newest automotive advancements today, the reduces fuel consumption and emissions that contribute to air pollution. GM fuel savers can be easily installed to a Chevrolet or Pontiac. A GM Fuel Saver may simply be strapped around the fuel supply line and will require no cutting of pipes or need of a power supply.
