Bonjour

Exhaust Emissions Controls
The exhaust missions controls include three systems: PGM-FI, Ignition Timing Control, and Three Way Catalytic Converter. These three systems work together to control the engine’s combustion and minimize the amount of HC, CO, and NOx that comes out the tailpipe. The exhaust emissions control systems are separate from the crankcase and
evaporative emissions control systems.
PGM-FI System
The PGM-FI System uses sequential multiport fuel injection. It has three subsystems: Air Intake, Engine Control, and Fuel Control. The Engine Control Module (ECM) or the Powertrain Control Module (PCM) uses various sensors to determine how much air is going into the engine. It then controls how much fuel to inject under all operating
conditions.
Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amount
of HC, CO, and NOx produced.
ThreeWay Catalytic Converter
The three way catalytic converter is in the exhaust system. Through
chemical reactions, it converts HC, CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), dinitrogen (N ), and water vapor.
Replacement Parts
The emissions control systems are designed and certified to work together
in reducing emissions to levels that comply with the Clean Air Act. To make sure the emissions remain low, you should use only new Honda replacement parts or their
equivalent for repairs. Using lower quality partsmay increase the emissions from your vehicle.
The emissions control systems are covered by warranties separate from the rest of your vehicle. Read your warranty manual for more information.
J'espère que cela pourra quand même vous être utile.
