The Action Reaction Design embodies both the rotary and the reciprocating piston designs and operates on the four stroke, one cycle principal, producing one power stroke per piston, per revolution of the crankshaft.

The AR engine uses principles found in both types of these conventional engines. It has the ported intake and exhaust of the rotary engine, with the piston scavenging of the four-stroke reciprocating engine. The superior breathing characteristics and power output is a major advantage of this design.

The contra-rotating rotor and crankshaft enhance the mechanical efficiency, whereas in conventional engines, mechanical efficiency is lost through the transfer from the piston to the rotating crankshaft.

In the AR engine concept, the perpendicular forces act in the same direction as the moving rotor, giving much lower friction losses.

THE ACTION REACTION ENGINE

The ActionReaction engine delivers its horsepower and torque in a similar manner to the conventional four-stroke internal combustion engine, however, because each cylinder fires once per revolution there is a significant increase of the engines output.

The AR engine also has direct fuel injection, which coupled with its other unique features, is designed to give greater fuel economy.

the Engine consists of:

The rotational characteristics of the engine are achieved through a set of specially designed timing gears.

THE BASIC PRINCIPLE

The rotor is mounted with bearings inside the stator and is free to turn in a radial fashion within that part. The crankshaft is mounted with bearings inside the rotor and is free to turn in a radial fashion within that part.

With specially designed timing gears adapted to the unit, linking all three components together and with the stator mounted in a fixed position, the gearbox will only allow the crankshaft to rotate in one direction, provided the rotor rotates in the opposite direction the exact same number of degrees as the crankshaft.

Rotating the crankshaft through 360 degrees causes the rotor to travel the same distance in the opposite direction this effectively causes the pistons to travel up and down the cylinders twice giving a four-stroke cycle for each piston every single revolution of the engine.

MARKET POTENTIAL

The unique features of the AR engine discussed throughout this presentation, offers opportunities to all known users of internal combustion engines. While slight modifications may be necessary to accommodate fuel and application type, the requirement for high torque, low engine revolutions, reduced fuel consumption and emissions, is universal.

Many engines that require a high torque output have to sacrifice either weight and/or operate at high engine revolutions. Both of these factors equate to an increase in fuel consumption. The AR engine with its lower rpm and high power to weight ratio eliminates this problem and presents efficient fuel consumption and exhaust emission qualities.
