It is mainly used in food additives, electrical insulation in cables and wires, plastic compounds, and in cosmetics.

Polyisobutylene Amine (PIBA)

It is mostly being manufactured to inform of a block copolymer. Besides, it is common finding saturations present in the backbone. Thermoplastic elastomers are composing of outer blocks which are glassy and inner blocks which are rubbery.

How to Clean a Fuel Injector

To clean your car’s fuel injector, you can either do it yourself or hire an experienced cleaner to do it for you. Here you can find a complete guide on how you can clean fuel injector:

  1. Buy a fuel injector cleaning kit – visit an auto supply shop and buy a cleaning kit which basically should contain a fuel pressure gauge, a hose, and a bottle of injector cleaner.
  2. Locate the fuel injector – since different cars have different types of engines, the layout may differ. Therefore, you can look into your instructor’s manual, read articles, or watch online videos to know where your car’s fuel injector are located.
  3. Disconnect the car’s fuel pump from the fuel injector – after detaching the pump, you can use a fuel return line or a U tube to safely return the fuel that’s contained in the tank to the fuel tank. Take caution to keep any source of fire away to prevent fire outbreaks. You have to disconnect the pressure regulator vacuum line before proceeding to the next step.
  4. Connect the cleaning kit – using a manual, connect the kit to the fuel port, and then start the engine. There should be no traces of fuel in the injector because the cleaning fluid might be flammable and the cap of the fuel tank should be removed to prevent pressure build up.
  5. Reassemble the fuel lines – after cleaning is done, remove the kit and reassemble all the fuel lines. Verify the components are installed correctly by testing or even driving your car for some minutes.

Before you start the engine, make sure the fuel pump is turned off and remember to verify the fuel pressure using the kit’s pressure gauge to ensure that it matches the recommended pressure. The entire cleaning process should take 5-10 minutes for thorough cleaning. You should leave the engine to run on its own because it will eventually shut down on its own after the cleaner is used up.
