How to Buy a Good Quality Fuel Injector

Fuel Injector

Getting fuel directly to an engine is accomplished through an electronic fuel injector; with each cylinder getting its own dose of fuel which is much more efficient than the ways carburetors would send fuel directly to the engine in the past. Until fairly recently, fuel injectors were not common on gasoline-powered cars, but diesel vehicles have used fuel injectors from inception starting with gasoline-powered airplane engines early in the twentieth century.

Race cars utilized fuel-injected engines in order to boost power and performance; but it took an increase in emissions regulations to truly bring fuel injection into the forefront in the 1980s.

  • Multiport fuel injectors made the injection process even more efficient as they target the fuel directly into the intake valve, allowing more fuel to be used more effectively.

  • Throttle body fuel injectors are also a different option as they are electronically controlled, possibly offering a more effective air-fuel ratio no matter the current speed of the engine.

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

  • A large number of different sensors are utilized to determine the exact perfect ratio of fuel to air to inject at any given time based on driving conditions.

  • If you’re getting a refurbished fuel injector, you’ll want to check and be sure that there are no clogs.

  • Replacing a fuel injector by yourself can be a challenging task; one that requires a special tool called a fuel injector puller. Keep in mind that the fuel injector will be under high pressure, so you’ll want to bleed the system before making any changes.

  • A good fuel injector will offer the correct ratio of fuel to air for your particular vehicle. As there are differences in requirements across manufacturers, check carefully to ensure you have the correct part for your particular needs.

Having the correct fuel injector can make a huge difference in the performance of your vehicle.
