Emission Control System Information

Source of 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.

Wacker utilizes lean carburetor settings and other systems to reduce

the emissions of carbon monoxide, oxides of nitrogen, and

hydrocarbons.

The U.S. and California Clean Air Acts

EPA and California regulations require all manufacturers to furnish

written instructions describing the operation and maintenance of

emission control systems.

The following instructions and procedures must be followed in order to

keep the emissions from your Wacker engine within the emissions

standards.

Tampering and Altering

Tampering with or altering the emission control system may increase

emissions beyond the legal limit. Among those acts that constitute

tampering are:

•Removal or alteration of any part of the intake, fuel, or exhaust

systems.

•Altering or defeating the speed-adjusting mechanism to cause the

engine to operate outside its design parameters.

Problems That May Affect Emissions

inspected and repaired by your servicing dealer.

•Hard starting or stalling after starting.

•Rough idle.

•Misfiring or backfiring under load.
