Appeal No. 2002-1828
Application 09/424,606
consider that claims 13 through 23 fall with claim 12 and that
claims 25 and 26 fall with claim 24.
The next rejection for our review is that of claims 12
through 27 under 35 U.S.C. § 102(b) as being anticipated by
Kamura. Having reviewed Kamura, particularly Figures 1, 4, 5 and
6, and the disclosure associated therewith, we agree with the
examiner that the later lean mode, seen in Figure 1 as being
performed during the compression stroke, corresponds to
appellant’s first mode, and that the earlier lean mode and
stoichiometric mode, seen in Figure 1 as being performed during
the intake stroke of the piston, respectively, correspond to
appellant’s transitional operation of the second mode and normal
operation of the second mode.
Kamura notes (e.g., col. 3, lines 60+), that the invention
therein provides a control unit for an in-cylinder injection
internal combustion engine in which fuel is directly injected
into a combustion chamber and which is adapted to select,
according to an operation state of the engine, a compression
stroke injection mode for mainly injecting fuel at a compression
stroke and an intake stroke injection mode for mainly injecting
