Helps prevent the formation of oxides of nitrogen by recirculating a certain amount of exhaust as in inert gas through the intake manifold to keep deep peak combustion temperatures below what would form those chemical compounds. The computer determines when and how much exhaust to recirculate based on information from all its other sensors. It then actuates the EGR solenoid, which opens a vacuum circuit or operates and electronic circuit to actually work the EGR valve. The computer uses a dual cycle signal to activate the solenoid.
A flexible coupling between two shafts that allows each shaft to maintain the same speed regardless of operating angle.
