ABSTRACT:
This invention relates to mechanical/electrical generators and more particularly to improvements in mechanical internal combustion engine and electrical generator combinations for producing electrical energy.
BACKGROUND OF THE INVENTION
From early times man has sought better and easier ways of performing his day to day tasks, which required some form of energy to accomplish. In the earliest of times man could only count on his own energy to carry out these tasks. Eventually he had fire, then domesticated animals, soon he learned to make and use steam, and then came the internal combustion engine. Shortly thereafter came electricity. From the very beginning of the electric age man recognized the power of electricity, although he didn't know just what to do with it. He still used his own hands, the hands of friends, his livestock, steam engines and the internal combustion engine which was growing in popularity with each passing day. Electricity as we have learned, provides us with almost anything we need in the course of our lives from birth to death. Without electricity there would be no refrigerators, microwaves, televisions, radios, computers or a host of other electrified instruments useful to man. One only has to experience an electrical black-out to readily appreciate the vast array of uses electricity has been put to. As a matter of fact, man has now become almost completely dependent on electricity for every facet of life, whether at work or at home. Without it, he is in the dark, like his cave dwelling forefathers were and yet power failures are more frequent and longer than ever. Some power companies have even resorted to the tactic of strategic black-outs during the worst days of electrical demand, particularly in summertime due to the heavy demand of running air conditioners. One answer to the problem of electrical shortage is to buy more electricity from neighboring producers of electrical power, but this is not a long term solution.
Currently there is more demand for electricity. New uses for electricity are found everyday. As our population grows, new homes spring up everywhere, more factories are built to make more products and to supply jobs for all the new workers and for all that we require even more electricity. While the construction of new power plants is relatively infrequent, the need for emergency electric power generators has become common. Although the demand for emergency generators that are economical to use, dependable and affordable has never been greater this demand will be even greater in the future.
This invention seeks to meet the aforenoted demand and need for a portable, relatively light-weight, highly efficient, economical generator utilizing an internal combustion engine for driving an electro-magnetic coil to produce electrical energy.
BRIEF SUMMARY OF THE INVENTION
This invention is directed to an improved stationary or portable electrical energy source employing an internal combustion engine and generator combination and more specifically comprises a novel rotary internal combustion engine which integrates an electrical generator with an engine rotor. The engine's combustion cylinders and pistons travel along endless twin-cam tracks and preferably operate generally similar to a two-cycle engine at relatively fixed speeds to provide a highly efficient and powerful, small, lightweight internal combustion engine of flexible design capable of efficient operation while using a wide range of hydrocarbon fuels and at the same time maintaining an efficient low cost of production.
An important object of this invention, is to provide an internal combustion engine having vastly improved flexibility of design for all facets of infinitely variable combustion and subsequent power conversion.
Another important object of this invention is to provide an internal combustion engine having a prolonged dwell at the top of the piston stroke whereby the ignited air/fuel mixture in the cylinder is allowed to combust more completely while the piston is substantially stationary relative to its position in a related cylinder.
Yet another important object of this invention is to provide an internal combustion engine having a prolonged dwell at the top of the piston stroke whereby the ignited air/fuel mixture in the cylinder is allowed to expand more completely to provide a means to generate much greater internal cylinder pressure while the piston is substantially stationary relative to its position in a related cylinder.
Yet another important object of this invention is to provide an internal combustion engine requiring no form of head gasket which would limit the engines ability to withstand extremely high cylinder pressures.
Still another important object of this invention is to provide an internal combustion engine having an infinitely variable cam track configuration such that the most efficient transformation of the linear motion of a piston into the rotary motion of the engine/generators rotor can be achieved.
Another important object of this invention is to provide an internal combustion engine having prolonged dwell at the bottom of piston stroke whereby exhaust of spent gases is accomplished while the piston is substantially stationary relative to its position in a related cylinder.
Still another important object of this invention is to provide an internal combustion engine in which there is prolonged dwell at the bottom of a piston stroke such that each piston carrying cylinder may be cleaned or purged of all spent gases while the piston is generally stationary relative to its cylinder.
A still further object of this invention is to provide prolonged dwell at the bottom of the piston stroke in a multi-cylinder internal combustion engine whereby each cylinder is cleaned, purged and air cooled internally while exhaust valves are held open in a prolonged substantially stationary position.
Still another important object of this invention is to provide a two cycle, multiple cylinder and piston, internal combustion engine in which each piston has a prolonged dwell period, such that a related cylinder exhaust valve is in a complete state of closure prior to the introduction of fuel into the cylinder.
An additional object of this invention is to provide an internal combustion, two cycle engine embodying means productive of a prolonged dwell at the bottom of each piston stroke such that charging of a cylinder with fuel for the next combustion is accomplished while the piston is generally stationary relative to its cylinder.
A still additional object of this invention is to provide an internal combustion engine employing endless opposed twin cams for regulating piston movement with the twin cams providing an infinitely variable compression stroke for each piston to optimize combustion of a selectively suitable fuel.
A still further important object of this invention is to provide a two cycle style rotary engine embodying cam means capable of dictating multiple firings of each cylinder for each complete engine rotor revolution.
A further and most important object of this invention is to provide an internal combustion engine designed for use in a unitary engine/generator embodying the features of the aforestated objects.
Another important object of this invention is to provide a mechanical electrical means for generating electrical energy utilizing an internal combustion engine such that the rotary mass of an engine rotor assembly is the armature of the generator unit.
An overall object of this invention is to provide a compact, lightweight, means providing a highly efficient source of portable and stationary electrical power, and which is dependable in use, economical to manufacture and friendly to the environment.
Having described this invention, the above and further objects, features and advantages thereof will become readily apparent to those skilled in the art from the following detailed description of a preferred embodiment illustrated in the accompanying drawings.
