Carbon monoxide does not react in the same way, but it is toxic. Honda Motor Co., Ltd. utilizes appropriate carburetor settings as well as other systems, to reduce carbon monoxide and hydrocarbons. CRANKCASE EMISSION CONTROL SYSTEM The engine is equipped with a closed crankcase system to prevent discharging crankcase emissions into the atmosphere.
GENERAL INFORMATION EXHAUST EMISSION CONTROL SYSTEM The exhaust emission control system is composed of a pulse secondary air injection system and lean carburetor settings. No adjustment should be made except idle speed adjustment with the throttle stop screw. The exhaust emission control system is separate from the crankcase emission control system.
GENERAL INFORMATION EVAPORATIVE EMISSION CONTROL SYSTEM This device collects the fuel vapour from the fuel tank and is routed into the evaporative emission canister, where it is absorbed and stored while the engine is stopped. When the engine is running and evaporative emission (EVAP) one way valve is open, fuel vapour in the canister is drawn into the engine through the carburetor for reburning to avoid air pollution caused by fuel vapour diffused into the air.
