Cleaning injectors helps the car to operate stably, not be inert and fuel consumption. After a period of use, gasoline injectors will be contaminated with impurities on the needle tip and the needle hole leading to congestion.

Therefore, you should clean car injectors periodically every 20,000 km to ensure injectors always in good condition.

Why must clean gasoline injectors?

  • Clean the top of the piston, needle, needle hole.

  • Increasing the life of injectors.

  • Recovery of engine power.

  • Reduce fuel consumption.

  • The car operates smoothly and starts easily.

  • Reducing HC&CO emissions to help protect the environment.

Steps to cleaning the injectors for cars

Preparing instruments

  • Lock the fuel line valve.

  • Adjust the pressure gauge button to "0".

Stop pumping petrol

  • Open the fuel tank cap (to reduce the pressure in the tank).
  • Making gasoline pump stop working (interrupting lead line, relay, connector ...).

Connect injector cleaning tools

  • Remove the fuel supply hose from the rail.

  • Check for leaks of the contactor connector.

Exploding machine in moderation

  • Start the machine in moderation mode, about 20-25 minutes.

  • Should turn off the engine when signs of running out of sad cleaning solution, do not let the engine completely die due to running out of fuel.
  • Before removing any of the engine's fuel supply line, pay attention to the pressure that is in the piping. Carefully remove to reduce the pressure in the fuel line, and use a rag to soak up leaking fuel during operation.
  • Do not use a wrench to tighten the connector on the scalpel bottle.
