Intake air manifold
The S85 is equipped with a separate intake air
manifold for each cylinder bank. The intake air
manifolds are connected via hoses to the
throttle valve assemblies.
10 individual throttle valves control the air
supply for the S85. The individual throttle
valves of each cylinder bank are operated
separately by an actuator unit and operating
shaft. The actuator motors operate
independently.
The throttle valves are set with respect to each
other (as on S54). There are no facilities for the
synchronization of the cylinder banks with
respect to each other as well as for setting the
full load stop. The necessary corrections are
undertaken by the engine management (see
section entitled Engine Management
MS_S65).
Idle control system
The idle speed is controlled by two idle speed
actuators that route the intake air from the
intake air manifolds directly into the idle air port
of the respective cylinder head. Each cylinder
bank is controlled individually.
