The original system used a simple feedback mechanism to control vane
position, very little logging capability was incorporated and there was no ability to log environmental variables.
Each supplier will have two control valves - one for the automated control, and a second to monitor high pressure in the event of failure in the primary control vane
or its operating system.
This all-aluminum engine, built at the Ford Essex Engine Plant in Windsor, Ontario, also features Ti-VCT, but whereas the V6 system uses electronic solenoid valves to direct high-pressure oil to control vanes
in each of the camshaft sprocket housings, the V8's system is actuated by camshaft torque, with assistance from pressurized oil.
Manufacturers of surge control vanes
include APCo Willamette/Valve and Primer Corp.
is a leading supplier of control vanes
, regulators, transmitters, analyzers, process management systems, software, and related services.
