Emissions Secondary Air System
The secondary air system is located on the upper rear cab support and engine. This system introduces air into the
exhaust system for more complete burning of the exhaust emissions. The air control valve (A) is operated by intake
manifold pulses from the intake manifold, which releases the air to the one-way valve (B) to combine with the pull of the
exhaust gas stream from the cylinder head. Check the air control valve (A), one-way valve (B), filter housing (C) and
related components according to the maintenance schedule in Chapter 2 for proper operation and emissions compliance.
