Buy Used and Reconditioned Fuel Injector parts at Breakeryard

What Are Fuel Injectors and What Do They Do?

Fuel injectors are precision-engineered components in a vehicle’s fuel delivery system, responsible for spraying fuel into the engine’s combustion chamber in a fine mist. This ensures optimal fuel-air mixture for efficient combustion, improved performance, and reduced emissions.

Modern cars use electronic fuel injection systems to precisely control how much fuel is delivered based on engine speed, throttle position, and load. Faulty or clogged injectors can lead to poor engine performance, reduced fuel economy, and increased emissions.

Whether you're replacing a failed unit or upgrading for better performance, you can buy injectors from Breakeryard.com at a fraction of the cost of main dealer prices.

How Do Fuel Injectors Work?

Fuel injectors are mounted in the intake manifold or directly in the combustion chamber, depending on the engine type. 

Each injector receives pressurised fuel from the fuel rail and atomises it through a nozzle into the engine cylinder. A computer-controlled engine control unit (ECU) precisely times and controls the injector’s spray for efficient combustion.

The result: smooth engine running, consistent power delivery, and reduced fuel wastage.

Types of Diesal and Petrol Injectors

Different vehicle models use different types of injectors, depending on engine design and performance requirements:

• Port fuel injectors (P-FI) – Spray fuel into the intake ports
  Direct fuel injectors (GDI/FSi) – Inject fuel directly into the combustion chamber
• Throttle body injectors (TBI) – A centralised system used in older engines
• Common rail injectors – Used in modern diesel engines for high-pressure delivery
   

When replacing, it's vital to match your vehicle's engine type and injector spec.

Common Signs Your Fuel Injectors Need Replacing

Faulty injectors can cause a variety of engine issues. Look out for the following warning signs:

• Engine misfires or rough idling
• Poor acceleration or reduced power
• Increased fuel consumption
• Black smoke from the exhaust
• Strong fuel smell around the engine
• Engine warning light on the dashboard
   

If any of these issues appear, it's likely time to consider replacement.
