A variable cycle / variable stroke profiled circular cam attached to a drive
shaft motivated by
multiple pistons reciprocating within annularly displaced stationary cylinders
. The engine is
designed to require a minimum of engine components to operate thus achieving a
reduction in
manufacturing time, cost, and energy requirements. Due to the low engine
parts, operating
efficiencies will result in lower fuel consumption and lower exhaust
temperatures compared to
existing engines of equivalent horsepower. Of importance is the function of
the variable
cycle/stroke feature profiled on the operating cam attached to the main drive
shaft. The
profiled cam ensures that the intake and compression strokes operate at one
half the piston
travel distance as that of the power and exhaust strokes. The pistons operate
independently
thus allowing for the profiled cam to be configured for a variable four
cycle/stroke operation.
This engine design can use many existing modified components in the
manufacturing process
thus reducing the need for re-tooling requirements. The engine can be a direct
replacement for
all existing engine applications including automotive, aviation, marine and
power tools. The
engine design is capable of expanding from 1 cylinder to a multiple of
cylinders depending on
operational requirements.
