Emission Control System Information
Source of Emissions
Exhaust gas contains carbon monoxide, nitrous oxide (NOx), and
hydrocarbons. It is very important to control the emissions of NOx and
hydrocarbons as they are a major contributor to air pollution. Carbon
monoxide is a poisonous gas. The generator engine utilizes a precise air-
fuel ratio and emission control system to reduce the emissions of carbon
monoxide, NOx, hydrocarbons.
POLARIS utilizes appropriate air-fuel ratios and other emissions control
systems to reduce the emissions of carbon monoxide, oxides of
nitrogen, and hydrocarbons. In addition, POLARIS fuel systems utilize
components and control technologies to reduce evaporative emissions.
To keep the engine emissions within the emission standards, the
following procedures must be followed:
Alterations
Altering the emission control system may increase emissions beyond
the legal limit. Some possible alterations are as follows:
• Removal or alteration of any part of the intake, fuel, or exhaust
systems
• Altering or defeating the governor linkage or speed-adjusting
mechanism to cause the engine to operate outside its design
parameters
