Dummy injector method
* For All Petrol Engine Cars
-Clean the following parts: Intake Vale, Combustion Chamber, Vacuum Hose
-Test the following parts: Engine System Pressure, Petrol Pump Pressure,
Vacuum System Pressure

* Fuel Injector
The opening of the fuel injector is as thin as the human hair.
The accumulation deposits at the tip would affect and upset the air/fuel mixture.
-The Problem Symptoms:
Stumble during acceleration. Power Loss.
Emissions of Hydrocarbons and Carbon Monoxide Increases.

* Intake Valve
While the engine is warming up, the intake valve absorbs fuel and leaves out
the air/fuel mixture.
-The Problem Symptoms:
Poor Driveability. Power Loss.
Emissions of Hydrocarbons and Carbon Monoxide Increases.

* Combustion Chamber
As the deposits keep accumulating, the compression temperature increases,
and lead to auto-ignition of the air/fuel mixture.
-The Problem Symptoms:
Poor Acceleration, Run-On, Knocking, Pinging,
Octane is increasingly required.
Emissions of Nitrogen Oxide increases.
