SCHEDULED MAINTENANCE
Exhaust Gas Recirculation (EGR) System
This system helps to reduce exhaust emissions, particularly oxides of
nitrogen. The EGR system works by introducing sma1lamounts of exhaust
gas into the fuel/air mixture that is being inducted into the combustion
chamber. This small amount of exhaust gas causes the combustion
temperature to be reduced enough so that oxides of nitrogen levels are
significantly reduced.
Catalytic Converter (If So Equipped)
The catalytic converter, which looks like a small stainless steel coated
muffler, has a ceramic honeycomb-like core coated with platinum and
palladium. These precious metals stimulate a chemical reaction that
assists in converting carbon monoxide and hydrocarbons into carbon
dioxide and water vapor.
Inlet Air Temperature Regulation
This device, which is part of the air deaner, keeps the temperature of the
air
entering the carburetor at about 100 degrees F whenever sufficient
heated or cool air is available_ By keeping the air at a constant, moderately
high temperature, engine cold driveaway and warm-up is improved and
carburetor icing is minimized.
Thermactor Exhaust Control System
The thermactor exhaust control system reduces the hydrocarbon and
carbon monoxide content of exhaust gases by continuing the oxidation
of unburned gases after they leave the combustion chamber. This is
achieved by using an air pump to inject fresh air into the hot exhaust
stream after it leaves the combustion chamber. The fresh air mixes with
the hot exhaust gases and promotes further oxidation of both
the
hydro-
carbons and carbon monoxide thereby reducing their concentration and
converting some of them into harmless carbon dioxide and water.
Emission System Warranty
Ford warrants to the eligible ultimate purchaser and each eligible subse-
quent purchaser that the purchaser's vehicle (or engine) is designed, built,
and equipped so as to conform at the time of sale with the emissions
regulations, applicable at the time of manufacture, issued under either
Section 202 of the Federal (U.S.) Clean Air Act or regulations issued
under the MotorVehicle Safety Act of Canada, depending upon whether
the vehicle was purchased in the U.S. or Canada and that it is free from
defects in materials and workmanship which would cause it to fail to
conform with applicable regulations within the period of 5 years or
50,000 miles , whichever occurs first.
