13 Emissions Control Systems Information and Warranty: KOHLER
The Emission Control Warranty and associated information is valid only for the
U.S.A., its territories, and Canada.
13.1
Emission Control System Background Information
Introduction
Wacker Neuson engines/equipment must conform with applicable Environmental
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 provided 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 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.
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 emissions
beyond the legal limit. If evidence of tampering is found, Wacker Neuson 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 systems.
■
Altering or defeating the speed-adjusting mechanism causing the engine to
operate outside its design parameters.
