Emission Control System Background Information
Introduction
Wacker Neuson engines/equipment must conform with applicable Environ-
mental Protection Agency (EPA) and California Air Resource Board (CARB)
emissions regulations. These regulations require that manufacturers warrant
the emission control systems for defects in materials and workmanship.
Furthermore, EPA and CARB regulations require all manufacturers to furnish
written instructions describing how to operate and maintain the engines/
equipment including the emission control systems. This information is pro-
vided with all Wacker Neuson engines/equipment at the time of purchase.
Exhaust emissions
The combustion process produces carbon monoxide, oxides of nitrogen, and
hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very impor-
tant 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.
Problems that may affect emissions
If any of the following symptoms arise, have the engine/equipment inspected
and repaired by a Wacker Neuson dealer/service center.
• Hard starting or stalling after starting
• Rough idling
• Misfiring or backfiring under load
• Afterburning (backfiring)
• Presence of black exhaust smoke during operation
• High fuel consumption
Tampering and altering
Tampering with or altering the emission control system may increase emis-
sions beyond the legal limit. If evidence of tampering is found, Wacker Neu-
son may deny a warranty claim. Among those acts that constitute tampering
are:
• Removing or altering of any part of the air intake, fuel, or exhaust sys-
tems.
• Altering or defeating the speed-adjusting mechanism causing the engine
to operate outside its design parameters.
