What is a Fuel Injector

Fuel Injectors: What is a Fuel Injector?

A fuel injector is a key component of a vehicle’s fuel delivery system that sprays fuel directly into the engine’s combustion chamber or intake manifold. Its primary role is to ensure that the right amount of fuel mixes with air for efficient combustion. By precisely controlling fuel delivery, injectors help engines run smoothly, optimize performance, and reduce fuel consumption.

At New England Injectors, we provide high-quality OEM fuel injectors and rebuild kits that ensure reliable, consistent performance for a wide range of vehicles and engines. Whether you’re restoring a project car, upgrading a turbo setup, or maintaining your daily driver, our quality-tested, flow-matched injectors deliver the precision and power your engine needs for efficient combustion.

Fuel injectors are also critical for controlling emissions. Properly functioning injectors maintain the correct air-fuel ratio, preventing excess fuel from entering the engine and reducing harmful exhaust emissions. Without well-maintained injectors, engines can experience lower efficiency, higher emissions, and decreased overall performance.

Types of Fuel Injectors

Fuel injectors come in different types depending on the vehicle’s design and performance requirements. The two most common types are:

  • Port Fuel Injectors (PFI): These inject fuel into the intake manifold just before the intake valve. They are reliable, cost-effective, and suitable for most everyday vehicles.
  • Direct Fuel Injectors (DI): These inject fuel directly into the combustion chamber, allowing for more precise fuel control and higher engine efficiency. DI injectors can improve power and fuel economy, but are typically more expensive and require careful maintenance.

Each type has its benefits and drawbacks. Port injectors are easier to maintain and less costly, while direct injectors offer higher performance and better fuel efficiency, but may be more sensitive to fuel quality and deposits.
