BACKGROUND
‘The discussion below is merely provided for penerl backs
ground information and is not intended tobe wsed ns ana in
‘determining the scope of the elzimed subjest matter
“The present invention relates to engines ofall sors. More
particularly, the present invention relates to an internal cr
bustion engine of a bare-type configuration in which the
‘ylinder axes are arranged around a cena longitainal axis
‘oF the engine, and even more particularly to a barrel-ype
‘engine having «rotating eylinder bank.
Internal combustion engines have been around fora long
time. The hasie components of the engine are well known ia
the art and include the engine block, eylinder head, cylinders,
pistons, valves, crankshll and camshaft. Thecylinder heads
‘ylinders and tops of the pistons typically form combustion
‘chambers into which fuel and ai are introduced so that com- 3
bustion takes place, Useful work is generated from the hot,
_gasents products of combustion acting disctly on the top oF
‘rovin surface of te piston, Generally, reciprocating lina
‘motion of the pistons within the eylinders is transferred to
rotary motion of a crankshaft via connecting rods. One com-
‘mon internal combustion engine is known as an Otto-type
ietnal combustion engine and employs a four-stroke eyele
jn which power is derived Irom the combustion process over
four separate pistons movements (stokes): intake stroke,
‘compression stroke. expansion (power) stroke, and exhaust
stroke, In traditional Ottostype automotive engine applica-
tions, the eylinders are typically stationary and are typically
arranged in one of three ways: (1) single row Gin Line) with
the centerline of the cylinders commonly verieally oriented:
(2) 8 double row with the eenterlines of opposite eylinders
converging ina V (V-engine); or 3) two horizoata, opposed
rows (opposed or pancake engine). Two additional Otto-ype
‘slinder contigurations were also experimented with, prin
rily berwoon 1900 and 1980, and inehude (1) a radial configu-
ration where the cylinder axes are arranged like spokes of @
‘whcel wit the ner ml ends mounted on a common crank
shaft journal, and (2) barrel configuration wih eylinderaxes
arranged paralle] around the central longitudinal axis of the
‘engine. Barrel configurations generally include a stationary
‘linder bank and the power i transferredto the ranksha in
‘one of three ways (1) with the lower ends of the connecting
rods connected ta gear arrangement, 2) with the lower ends
‘ofthe crankshaft connected toa wobble plate, and (3) with the
lower ends of the rods pushing a cam sic,
‘A subelass of barrel engines are those wit a rotating eyl-
inder bank and such engines generally com in one of three
‘configurations: (1) a two of foureyele arrangement in which
the rotating eylinder bank drives an angle thros plate from
‘hich powers taken ofasshowen by way of examplein US.
Pat, Nos. 980.491; 1,345,808; 2.382,280 and 4.779.579: (2) a
two-cycle arrangement in which a pai of rota
banks share a common eylinder head unit and

‘outer rod ends each drive an angled thrust plate as shown by
‘way of example in US. Pat. Nos. 968,060; 1,285,664 and
1,779,032; and (3)atwo-eyelearrangement in which pairof
‘tating finder banks share a common piston and in which
pair eylinder head units are provided at each end thereof as
shown by way of example in ULS. Pat. Nos. 3.830.208 and
103,778. Its believed, both radial and haere engines, in
particular, fll out of favor after World Wat I
‘Boginning inthe early pat of the twentieth century, the
conventional Oto-typereeprocating engine began to assume
‘dominanceas the most practical approach, even though twas
recognized thatthe thennodynamic efliieney of the engine
was sueh that about two-thitds of the energy developed
‘through the combustion of the fuel was wasted. That is,
roughly of the fuel energy is delivered t the erankshaft as
useful work, % is lost in waste heat through the eyl
alls, heads and pistons, and Ys lost out ofthe exhaust.
‘The Wankel engine, whichis also known asa rotary engine
js denoted as such because it utilizes a single triangular rotat-
ing piston which Tomas combustion chambers a it rotates
within a stationary figure eight-shaped “cylinder”. The
‘Wankel engine does not employ connecting ros as the ota
ing piston is linked direlly tothe crankshaft. The Wankel
engine is also a four-stroke eyele engine, and while it has
several advantages aver the Otto-type engine, it produces
igher emissions, has a shorter lifespan, and lcks torque at
Jow speeds, which leads to greater fuel consumption,
Applicant's U.S. Patent Application Publication No, 2003/
(0131807 provides an improved barrel configuration sith a
rotating cylinder bank and angled thrust plate. However, it is
lays desirable to make improvements such as but aot in
ited {0 improvements in thermodynamic efficiency, exis
sions, manufocturablity, andlor power or torque of the
engine

445, The cylinder bank assembly 12 inclides a plurality of
supporthousing 600, An outer covers indicated a 601, Thus,
inthis embodiment the bearings (not shown) are generally
about the support shaft 178 and not on the periphery ofthe
‘ylinderbank 12s in theearlier exemplary embodiment. The
‘entra support shaft 175 permitsa common exhaust manifold
{602 with flat exhaust seal at the bottom of the engine. The
length and shape of the exhaust pipes 604 from the eylinders
to the common exhaust manifold 602 can be adjusted to tne
the exhaust gases for desired Helmholtz effect.
‘As illustrated in FIGS. 18 and 16, the common exhaust
‘manifold 602 includes a stationary exhaust gs pickup 610, 2
rotating plate 612 which isattached to the ends of the rotating
pipes 604, and a rotating seal (not shown) between the star
tionary exhaust gas pickup 610 and he rotating plate 612. The
‘exhaust gas pickup 610 includes ablowdown area 620 which
receives the initial exhatst gases which are under the highest
pressures, anda secondary exhaust chamber 622 which con-
tinues forthe balance the exhanst stroke, The exhaust gases
from the blowdown area 620 Teed direely into a commen
stationary tail pipe 624 trough an opening while the exhaust
gases from the secondary exhaust chamber 622 first move in
the direction ofthe rotating exhaust plate 612 between a flow
plate 626and the tating plate 612 and then loop back under-
‘eat the How plate 626 othe blow down area 620 where they
flow into the til pipe 624. A venturi effect is thus created in
the stationary exhaust pickup 610 between the Blowdown
ates 620 and the secondary exhaust chamber 622 wherein the
higher pressure blowdown gases from one cylinder pull dae
remnant gases from the preceding eylinder out the tal pipe
624. The rotating seal is made from conventional material and
‘positioned between the rotating plate 612 andthe stationary
‘exhaust gas pickup 610 to prevent exhaust gases fom leaking
‘out and from leaking between the blow down ates 620 and the
secondary exhuust pickup 622. It may be desirable to back
pressure the exhaust seal to make sure there sno exaust as
Feakage.

‘Wiha is claimed is
1. An engine block assembly comprising:
Stationary housing;
‘cylinder bank rotatably mounted to the housing about a
‘central longitudinal axis, the cylinder bank having.
plurality of eylinders therein radially distanced from the
‘central longitudinal axis, each eylinder having assoc
ated therewith a eylinder wall formed about a major
ylinder axis;
plurality of pistons wherein one pistons provided in each
‘lindero form a combustion chamber therein, wherein
‘ach piston sequentially moves from a down most posi-
tion within the cylinder oan up most position within the
