air therein'to form a combustible mixture, means
said cylinder banks are disposed to form a dihe
for igniting said combustible mixture in oppos
dral angle whose degree is identical with that of 5 ing pairs of cylinders simultaneously; means for

nular shim-plates, whose bore coincides with cyl
cycle type comprising, a crankshaft, a crankcase 10 inder bore, interposed between each cylinder and
including oil reservoir, a plurality of cylinders ex
its head, or between each cylinder and the crank
tending radially from said crankcase to form
case; and means for supplying fuel to the in

nections, for said conduit with the fuel injecting
termittent passage of air from conduit, or scoop,
into the cylinder, 8, port, or ports, so situated in
each cylinder as to be exposed during ?nal phase
of piston’s downstroke and initial phase of up
stroke and otherwise occluded by piston, means
for substantially coinciding opening and closing
of the inlet and outlet Valves for each cylinder, an
exhaust. stack, having a rearwardly directed out
let opening, adapted to receive and convey gases
from outlet port, or ports, of cylinders, means for
creating a forced draft rearwardly in said air
and exhaust conduits and thru cylinders when
valve means are open for scavenging combustious
product gases and charging cylinders with fresh
means.
12. Structure according to claim 1 wherein the
exhaust conduit is provided with a rearwardly
directed jet opening, and wherein means are pro
vided for propelling, or impelling, air rearwardly
in both of said air conduits, thru said shells ex
ternally past cylinder, internally thru cylinder
when inlet and outlet means thereof are open,
for propelling, or impelling, exhaust gases and
coolant air rearwardly in said exhaust conduit
and expelling same from said jet opening for pro
ducing a jet reaction propulsive e?ect forwardly.
