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.
