: BLOW-BY VAPOR

When the engine is running, the intake air bypass
control thermal valve sends air to the injectors.
The throttle body is a single-barrel side draft type. The
lower portion of the throttle valve is heated by engine
coolant from the cylinder head. The idle adjusting
screw, which increases/decreases bypass air, is on top
of the throttle body.
The TWC converts hydrocarbons (HC), carbon
monoxide (CO), and oxides of nitrogen (NOx) in the
exhaust gas to carbon dioxide (CO2), nitrogen (N2), and
water vapor.
Refer to the System Diagram to see a functional layout
of the system.
The EGR valve is designed to lower peak combustion
temperatures and reduce oxides of nitrogen emissions
(NOx) by recirculating exhaust gas through the intake
manifold and into the combusition chambers.
The PCV valve prevents blow-by gasses from escaping
into the atmosphere by venting them into the intake
manifold.
