Emission Control System Information - Honda Marine BF115A Owner's Manual

TECHNICAL AND CONSUMER INFORMATION
Emission Control System
Information
Source of Emissions
The combustion process produces
carbon monoxide, oxides of nitrogen,
and hydrocarbons. Control of
hydrocarbons and oxides of nitrogen
is very important because, under
certain conditions, they react to form
photochemical smog when subjected
to sunlight. Carbon monoxide does
not react in the same way, but it is
toxic.
Honda utilizes appropriate air/fuel
ratios and other emissions control
systems to reduce the emissions of
carbon monoxide, oxides of nitrogen,
and hydrocarbons.

PGM-FI System
The PGM-FI system uses sequential
multiport fuel injection. It has two
subsystems: Engine Control, and
Fuel Control. The Engine Control
Module (ECM) 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
The system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The U.S. and Calif ornia Clean
Air Acts
EPA and California regulations
require all manufacturers to furnish
written instructions describing the
operation and maintenance of
emission control systems.
The following instructions and
procedures must be followed in order
to keep the emissions from your
Honda engine within the emission
standards.
