DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a new Stator-Rotor piston internal combustion engine accomplishing a new method for transmitting the explosion power to the engine shaft, using a new cylinder arrangement in form of two stator halves, and a flat rotor closed in-between, and being mechanically connected with all cylinders. Through increasing the number of cylinders and decreasing the cylinder displacement a general reduction of the compression stress and the power of explosion is achieved, and the already reduced power of explosion is transmitted in a best harmony between cylinder arrangement, kinematics and firing order smoothly to the engine shaft.
REVIEW OF THE PRIOR ART
As it is well known all kinds of piston internal combustion engines have more or less a vibrating run, in a considerable degree due to their cylinder arrangement, mechanical means for transmitting the explosion power, and the relatively great displacement of a single cylinder. This vibrating run affects negatively the engine work and the engine durability.
DEFINITION OF THE INVENTION
In accordance with the present invention there is provided a Stator-Rotor piston internal combustion engine having two mirror-imaged identical stator halves, both halves comprising an equal number of cylinders.
Also in accordance with the present invention there is provided a Stator-Rotor piston internal combustion engine comprising a flat rotor with two internal gear rings fitted on its periphery and two auxiliary gears sliding on its hubs, said rotor being fixed on the engine shaft between both stator halves, two rings mounted internally on the stator halves carrying the internal ends of the single crankshafts, and two engine lids carrying the engine shaft and the outer ends of the single crankshafts.
Further there is provided a Stator-Rotor piston internal combustion engine comprising two mirror-imaged identical stator halves with an equal number of cylinders, each cylinder having, except a conventional piston and a connecting rod, its own crankshaft and a drive gear mounted thereon, all drive gears being engaged with the rotor internal gear rings and the auxiliary gears, thereby transmitting harmoniously the explosion power from all cylinders to the rotor, respectively to the engine shaft.
In Stator-Rotor engine according to the invention all drive gears have equal pitch diameter, said diameter being smaller than the pitch diameter of the internal gear rings causing lower engine revolutions in comparison with those of the single crankshafts. The reduction of the engine revolutions depends on the transmission ratio between the drive gears and the internal gear rings.
The original and compact construction of the engine of this invention allows an alternator, a starter motor, and other engine aggregats to be mounted directly on the outer ends of the single crankshafts. It also allows this engine to be installed in different working positions without disturbing the engine work.
In an engine according to the invention each cylinder of one stator half explodes preferably always together with the one of the other stator half, thus, in each explosion are involved two cylinders contributing to a quiet engine run. To this Stator-Rotor engine construction according to the invention the cylinder firing is preferably set in a circular rotative order to improve further the smooth transmission of the explosion power to the engine shaft.
The invention is not restricted in regard to stroke principle of operation, cooling system, kind of fuel, and can be realized in all known versions in a conventional way.
