BALL PISTON ENGINES

INTRODUCTION

. The Ball piston engine (Wolf hart engine) is an [[internal combustion engine |internal combustion]] rotary engine that uses two intertwined rotors instead of reciprocating pistons.
A spherical piston rotates in combination with a spherical housing, whereby the rotational axes incline towards each other slightly.
In these way “strokes” are created within the rotational system generating periodic volumetric changes in the 2 working chambers adjacent to the dividing wall.

MODE OF OPERATION

. The basis of the design is ball pistons rolling on an eccentric track. The balls exert tangential force on the cylinder walls which turn the rotor
. Useful power is available at the rotor output shaft.
The combustion chambers are within the spinning rotor. Chamber porting for intake, compression, power, and exhaust strokes is achieved by passage of the chamber tops across an internal stator with appropriate feeds as the rotor spins.

DESIGN FEATURES

The basic operation of the new design is conventional for an internal combustion engine, i.e. a piston reciprocates within a cylinder, and with porting, implements the four strokes of the Otto cycle. However, there are a number of features that make this engine design favorable for high efficiency and emissions control.
The porting required for four stroke operation is achieved with no additional moving parts, and no valve train losses

MATERIAL SLECTION

. A series of tests to characterize friction and wear of various materials in a simulated ball piston engine/compressor were performed to aid in selection of production materials.
Another goal of the tests was to explor this machine could run without lubrication.
If un lubricated operation was not possible, tests with instrumentatio n would be used to confirm the lubricated operation of the machine and the resulting internal loads.
Friction at conventional piston rings, piston pin, and connecting rod/crankshaft bearing are eliminated ). The rotor/stator bearing is of a gas or fluid hydrostatic type, so friction is very low at that site.

WORKING OF ENGINES (SUCTION STROKE)

Beginning at top dead center (TDC) at 0 degrees rotation, the stator intake passage is open to the cylinder and a fuel/air charge is pulled into the cylinder as the ball piston moves radially outward for the first 90 degrees of rotation .
