Application No. 10/350,187
Kabasin does not provide sufficient details of the algorithms for generating the phaser
and ETC control signals to determine with any certainty whether any such condition
variable of the combustion of the combustion chamber will remain unchanged. The
examiner’s contention (supplemental answer, page 3) that, in essence, Kabasin’s
teaching that the disclosed algorithm with a corresponding phaser adjustment and valve
lift switching results in a smoother engine operation by eliminating sudden increase in
torque mandates that one condition variable of the combustion of a combustion
chamber does not change, is not well founded. Kabasin teaches in the last paragraph
in column 8 that:
Under certain engine operating conditions, the switching of
two-step switching device 16 could cause changes in engine
operation which might be perceived by a driver as
undesirable, such as, for example, a relatively sudden
increase in torque. Further, when engine operating
conditions are centered around a point corresponding to a
switching point for two-step switching device 16 engine
operation may be affected, such as, for example, by
oscillation or multiple switching of two-step switching device
16 between the high-lift and low-lift positions. As is more
particularly described hereinafter, switching control algorithm
200 controls the operation of two-step switching device 16,
