b.
The engine is certified if it has a special certifica-
tion label. Two types of labels that are used by Cat-
erpillar are illustrated. A Caterpillar dealer can also
inform you if the engine is certified.
c.
Efficiency of emission control and engine perfor-
mance depends on adherence to proper operation
and maintenance recommendations AND use of
recommended fuels and lubricating oils. It is rec-
ommended that major adjustments and repair be
made by your authorized Caterpillar dealer.
d.
Various chemical fuel additives, which claim to
reduce visible smoke, are available commercially.
Although additives have been used by individuals
to solve some isolated smoke problems in the field,
they are not recommended for general use. Federal
smoke regulations require that engines be certified
without smoke depressants.
e.
The corrective steps taken immediately upon discovery of worn parts, which may affect emission levels, will help
assure proper operation of emission control systems. The use of genuine Caterpillar parts is recommended. Suppliers
of non-Caterpillar parts must assure the owner that the use of such parts will not adversely affect emission levels.
f.
Regular maintenance intervals, along with special emphasis on the following items, are necessary to keep exhaust
emissions within acceptable limits for the useful life of the engine. If the engine is operating under severe conditions,
adjust the maintenance schedule accordingly.
g.
See your authorized Caterpillar dealer to help analyze your specific application, operating environment and mainte-
nance schedule adjustments.
h.
The following is an explanation of maintenance for emission-related components.
(1) Fuel Injectors or Nozzles. Fuel injectors or nozzles are subject to tip wear as a result of fuel contamination. This
damage can cause an increase in fuel consumption, the engine to emit black smoke, misfire or run rough. Inspect,
test, and replace if necessary. Fuel injectors can be tested by an authorized Caterpillar dealer.
(2) Turbocharger. Check for any unusual sound or vibration in the turbocharger. Inspect inlet and exhaust piping and
connections.
(3) Air/fuel Ratio Control.
