throttlePR090:Idle speed
regulation
programming
valuePR090≈ 0%
PR090, an adaptive built-in
action, is a stored parameter
designed to program variation
and engine ageing for the idle
speed regulator. These are
programmed only when the
engine is idling and warm, and
no electrical consumers
(electrical windscreen, air
conditioning, GMV, power
steering) have been selected.
Therefore it adjusts slowly.WITHOUT
6 PR091:Theoretical idle
speed regulation
OCR5% When the conditions for
regulation are met, the idle
regulator continually
repositions the motorised
throttle to keep the engine
speed at the idling speed
setting. The motorised throttle
opening ratio required to adhere
to the engine speed setpoint is
then given by parameter PR091.
