Here are the frequent asked questions regarding fuel injector cleaning in Jamaica

Question: What causes injectors to go bad when not in use?

Answer: The cause of fuel injectors going bad when not in use is in part because large parts of Jamaica contain enough moisture to cause corrosion/rust damage. The internals of injectors are made of various steel alloys that will corrode and or rust when in the presence of moisture.  Gum, varnish and other normal deposits can be removed by cleaning but once an injector dries out and the deposits hardened inside causing a pintle to get stuck to its seat, that injector will become inoperable and in most cases not possible to clean. Hence proper storage is a must!

Question:What are the symptoms of a dirty or clogged fuel injector?

Answer:Rough Starting, Misfiring, Hesitation/Stumbling on Acceleration, Shaking at Idle, Loss of Power, Engine Knock, Decreased Fuel Economy and Poor Performance are all symptoms of a poor performing injector

 

 

Question: What is your cleaning process?

Answer:

When the dirty fuel injector or clogged fuel injectors arrive for service those components that can be removed from the fuel injector such as O-rings, pintle caps and filter baskets are removed. The injector then is placed in an ultrasonic cleaning bath to clean the external part of the fuel injector. Once this is done the fuel injector is then connected to an electronically controlled machine that has the ability to pulls the fuel injector at various speeds. The injector is now placed in a second ultrasonic cleaning bath in such a way that the nozzle of the injector is amerced in a cleaning solution. The opening and closing of the pintle valve combined with the cleaning solution, agitated by the ultrasonic waves now cleans the internal components of the fuel injectors. The pulsation of the fuel injector combined with the ultrasonic waves force the cleaning solution to move up in the injector thus causing a flush effect on the injector and therefore expelling dirt and debris from the fuel injector internals.

Once it is established by means of flow testing and visual inspection that the spray patterns are correct and that the fuel injectors are clean, new filter baskets, pintle caps and O-rings are installed and the fuel injector is now ready for service again.

If after several cleaning attempts the flow pattern cannot be corrected and or quantity delivered by the injector is still not within spec the injector can be deemed as unserviceable and the fuel injector should be replaced.

Question: Do injectors have tolerances?

Answer:Yes, the injectors have a tolerance of 1 Micron, the finest tolerance of any mechanical component on the engine. Fuel manufactures claim their latest generation of fuel additives are designed to prolong the life of your engine by coating the metallic parts of the engine and reduce wear. These additives also coat the internal components of the fuel injector, restricting the fuel flow.

 

Question: Why should I have my fuel injectors serviced?

Answer:The fuel injector tips clog from solid deposits in the fuel (remember the bad gas saga in Jamaica in late 2015) and the filters/baskets collect debris which restricts fuel flow. On car cleaning or fuel additives won’t unclog a filter full of debris. When your injector is performing at optimum levels, it improves emissions, fuel economy, power and cold start dependability.

 

Question:How long can I store them after cleaning and before use?

Answer:We do not recommend that you have the injectors cleaned months before you are going to use them. It is possible that after a long time interval the injectors may stick closed. We will always try to help in freeing them off but this involves unnecessary delays and postal costs.

Question:If my injectors (or one of my injectors) is not serviceable, will I still be charged?

Answer:You will not be charged if we can not perform the service. If the injector is DOA (Dead on arrival) we will not perform the service. However, there is a minimum bench charge of $5 per injector for tests performed to declare the injector "DOA". The difference will be credited back to you.

Do you replace filters, seals etc?

Answer:There are dozens of different makes and styles of injectors, all with different filters, seals, and pintle caps. We cannot guarantee to stock all of them but we do keep a large range. For standard top feed Bosch Injectors we keep most spares. With regret if seals etc are not stocked then the old ones will be left in place. The report will indicate which have been renewed.
