Diesel Injector Ultrasonic Cleaning
Deep ultrasonic decarbonising of diesel injector bodies and nozzles.
Diesel injectors accumulate hard carbon and varnish that restricts flow and ruins atomisation. Our ultrasonic process removes external and accessible internal carbon far more thoroughly than soaking or brushing.
Important and honest: we offer ultrasonic *cleaning only* for diesel injectors. Modern common-rail diesel injectors operate at 1,000–2,500 bar and can only be flow-tested and calibrated on a dedicated high-pressure diesel bench, which we do not have. If you need certified common-rail bench testing we'll point you to a diesel specialist. For carbon removal, decoking and pre-refurb cleaning, ultrasonics are ideal.
What we clean
- Diesel injector bodies & nozzles
- Injector components pre-refurbishment
- Glow plugs & diesel small parts
- Injector seats & copper washers area
- Older mechanical/rotary diesel injectors
What's included
- Heated ultrasonic cleaning cycle
- Carbon & varnish removal
- Rinse and dry
- Visual inspection & report
- Seals refitted where supplied/available
Our process
Assess & disassemble
We inspect the injectors and remove any serviceable external components before cleaning.
Ultrasonic decarbonising
Injectors are run through a heated ultrasonic cycle with a diesel-safe solution to lift carbon and varnish.
Rinse, dry & inspect
Parts are rinsed, dried and visually inspected; we flag any that show wear or damage.
Benefits
- Thorough carbon removal
- Ideal prep before refurbishment
- Non-abrasive — no media blasting damage
- Honest scope, no false test claims
Frequently asked questions
Will this fix my common-rail diesel misfire?
Cleaning removes carbon, but it cannot correct worn internals or calibration — those need a high-pressure diesel bench. We're upfront so you don't waste money.
Do you flow-test diesel injectors?
No. Our rig is petrol-only for testing. Diesel is a clean-only service.
Petrol Injectors
Ultrasonic clean, flow-tested and re-sealed — like-new spray pattern.
Carburettors
Every jet, passage and emulsion tube cleared — carbs that run right again.
Motorcycle Carbs
Banks of 2, 4 or 6 stripped, ultrasonically cleaned and rebuilt.
