How to buy a good quality fuel injector

Fuel is supplied directly to the engine via an electronic fuel injector; each cylinder gets its own dose of fuel, which is much more efficient than the way carburetors sent fuel directly to the engine in the past. Until recently, fuel injectors were not common on gasoline-powered vehicles, but diesel vehicles have been using fuel injectors since the beginning, starting with gasoline aircraft engines in the early twentieth century.

Race cars used fuel-injected engines to increase power and performance; but it took tightening of emission regulations to really bring fuel injection to the fore in the 1980s.

• Multipoint fuel injectors have made the injection process even more efficient as they direct fuel directly to the intake valve, allowing more fuel to be used more efficiently.

• Throttle body fuel injectors are also another option as they are electronically controlled, possibly providing a more efficient air-fuel ratio regardless of the current engine speed.

• The most modern and advanced fuel injector systems use an opening and closing injector head that is controlled by the vehicle's computer in the ECU or engine control module.

• To determine the ideal ratio of fuel and air for injection at any given time, depending on driving conditions, a large number of different sensors are used.

• If you are buying a refurbished fuel injector, you will need to check and make sure it is not clogged.

• Replacing a fuel injector on your own can be a daunting task; one that requires a special tool called a fuel injector puller. Be aware that the fuel injector will be under high pressure, so the system must be bled before making any changes.

• A good fuel injector will provide the correct fuel to air ratio for your particular vehicle. Because there are variations in requirements from different manufacturers, check carefully to make sure you have the part that fits your specific needs.

The right fuel injector can make a big difference in how your car runs.
