engine HONDA RIDGELINE 2014 1.G Owners Manual

ÎThe burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas.The United States Clean Air Act
sets standards for automobile
emissions. It also requires that
automobile manufacturers
explain to owners how their
emissions controls work and what
to do to maintain them. This
section summarizes how the
emissions controls work. Scheduled
maintenance is on page
.
Your vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The positive crankcase ventilation valve routes
them from the crankcase back to the intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The onboard ref ueling vapor
recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .

ÎIn Canada,
Honda vehicles comply with
the Canadian emission requirements , as
specified in an agreement with
Environment Canada, at the time they
are manufactured.
System

The exhaust emissions controls
include four systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way
catalytic converter. These four
systems work together to control
the engine’s combustion and
minimize the amount of HC, CO,
and NOx that come out the tailpipe.
The exhaust emissions control
systems are separate from the
crankcase and evaporative
emissions control systems.
The PGM-FI system uses
sequential multiport fuel injection.
It has three subsystems: air intake,
engine control, and fuel control.
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.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust gas recirculation
(EGR) system takes some of the
exhaust gas and routes it back
into the intake manifold. Adding
exhaust gas to the air/fuel mixture
reduces the amount of NOx
produced when the fuel is burned.
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 ), nitrogen
(N ), and water vapor.
The emissions control systems are
covered by warranties separate
from the rest of your vehicle.
Read your warranty manual for
more information. The emissions control systems are
designed and certif ied to work to-
gether 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 f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.

The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on fire any
combustible materials that come
near it. Park your vehicle away
from high grass, dry leaves, or
other flammables.The defective three way catalytic
converters contribute to air pollution,
and can impair your engine’s
perf ormance. Follow these
guidelines to protect your vehicle’s
three way catalytic converters.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter inef f ective. Keep the engine well maintained.
Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.
The three way catalytic converter
contains precious metals that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converter is ref erred to
as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Honda part
or its equivalent.

Technical Inf ormation

If you take your vehicle for an
emissions test shortly after the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain ‘‘readiness
codes’’ that must be set in the on-
board diagnostics for the emissions
systems. These codes are erased
when the battery is disconnected,
and set again only after several
days of driving under a variety
of conditions.
If the testing f acility determines that
the readiness codes are not set, you
will be requested to return at a later
date to complete the test. If you must
get the vehicle retested within the
next two or three days, you can
condition the vehicle f or retesting by
doing the f ollowing.Make sure the gas tank
is nearly, but not completely,
full (around 3/4). Without touching the accelerator
pedal, start the engine, and let it
idle f or 20 seconds. Make sure the vehicle has been
parked with the engine of f f or 6
hours or more.
Make sure the ambient
temperature is between 40° and
95°F (4° and 35°C).
Keep the vehicle in Park. Increase
the engine speed to 2,000 rpm, and
hold it there until the temperature
gauge rises to at least 1/4 of the
scale (about 3 minutes).
Without touching the accelerator
pedal, let the engine idle for
20 seconds.Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
(80 to 97 km/h) for at least 20
minutes. Drive on the highway in
D. Do not use the cruise control.
When traffic allows, drive for 90
seconds without moving the
accelerator pedal. (Vehicle speed
may vary slightly; this is okay.) If
you cannot do this for a
continuous 90 seconds because
of traffic conditions, drive for
at least 30 seconds, then repeat
it two more times (for a total of
90 seconds).

Then drive in city/suburban
traffic for at least 10 minutes.
When traf f ic conditions allow, let
the vehicle coast f or several
seconds without using the
accelerator pedal or the brake
pedal.
Make sure the vehicle has been
parked with the engine of f f or 30
minutes.
If the testing f acility determines the
readiness codes are still not set, see
your dealer. 8.
