Throttle Body: Description and Operation
Electronic Fuel Injection
The throttle body assembly controls airflow to the engine by way of a butterfly type valve. The throttle position is controlled by a single lever and cable
linkage. The body is a singe piece die casting made of aluminum. It has a single bore with an air bypass channel around the throttle valve. This bypass
channel allows both cold and warm engine idle airflow control as regulated by an Idle Air Bypass (IAB) valve assembly mounted directly to the throttle
body. The valve assembly is an electro-mechanical device controlled by the Electronic Control Assembly (ECA). It incorporates a linear actuator which
positions a variable area metering valve.
The throttle body assembly also includes:
a.
A minimum idle airflow adjustment screw to set the throttle valve position.
b.
A throttle body mounted Throttle Position (TP) sensor.
c.
A PCV fresh air source upstream of the throttle valve.
d.
Two PCV orifices for air and crankcase mixture upstream of the throttle valve, and two downstream of the throttle valve.
