Why Test Your Petrol Injectors?

Fuel injectors are critical components of your engine’s fuel delivery system. They spray a precise amount of petrol into each cylinder, ensuring optimal combustion and engine performance. Over time, injectors can become clogged, develop leaks, or suffer from electrical faults. These issues can lead to a host of problems, including:

Reduced engine power and sluggish acceleration
Rough idling or engine misfires
Increased fuel consumption and poor economy
Higher emissions and potential MOT failures
Persistent check engine lights

Regular injector testing is essential for early detection of these problems, helping you avoid costly repairs and maintain your vehicle’s performance and efficiency.

Our Testing Process

We employ industry-leading methods and equipment to provide a thorough assessment of your injectors:

Visual Inspection: Every injector is carefully examined for signs of external damage, corrosion, or carbon build-up.
Electrical Testing: Using precision multimeters, we check the resistance of each injector coil to identify any electrical faults or shorts.
Static Flow Testing: Injectors are tested at a standard pressure (typically 3 bar/43.5 psi) to measure the volume of fuel delivered when held open. This reveals blockages or flow inconsistencies.
Dynamic (Pulsed) Flow Testing: Simulating real-world driving conditions, injectors are pulsed at various duty cycles to assess performance during idling, acceleration, and cruising.
Spray Pattern Analysis: We examine the atomisation and distribution of fuel to ensure a fine, even mist for optimal combustion.
Leak and Drip Testing: Injectors are checked for leaks at set pressures, ensuring no unwanted fuel enters the engine when the injector is closed.

All results are documented, and you receive a detailed report outlining the condition of your injectors and any recommended actions.

Cleaning and Restoration

If your injectors are found to be dirty or underperforming, we offer ultrasonic cleaning to remove stubborn deposits and restore flow rates. After cleaning, injectors are re-tested to confirm performance improvements. We also replace essential components such as O-rings, filters, and seals as needed.
