Global Environmental Protection

A philosophy being adopted and echoed around the world, a complex issue forcing government policy and political change.

The internal combustion engine, available and used around the world and long recognized as a major contributor to atmospheric pollution is now facing the demands of change.

In 1862 a French man, Mr. Beau de Roches, noted the possibility of producing useable energy from the burning of fuel in a device to be known as the internal combustion engine.

It was believed that to produce energy in the manner, four principal operating functions would be required by any design configuration:

Intake
Compression
Power
Exhaust


In 1872 a German, Dr. Otto, developed the Otto four stroke cycle engine based on Mr. Beau de Rochas original theories.
In 134 years the internal combustion engine has undergone no significant change to the basic design configuration, most modifications have been made to external components.


Fuel Delivery
Ignition
Turbo Chargers
Porting


In October 1993, US President Bill Clinton announced on world wide media that the US government was to heavily subsidize a consortium acting under a development mandate would within ten years and a budget of up to one trillion dollars, produce a new design configuration and prototypes to replace the existing internal combustion engines.
World wide, the future is demanding change.

Over many years, large sums of money have been invested by manufacturers around the world in search of increased engine out-put from smaller, more efficient engine designs.

The lack of success of new engine design concepts to progress research and development into a production engine demonstrates the technical and engineering difficulties.







The initial market selection for the OX2 engine will be suitably diverse to enable the company to demonstrate to a wide range of industries both the market and application potential of the OX2 engine.
In 134 years the internal combustion engine has gone from the theoretical stage of one man to a world wide industry, producing in excess of one hundred and fifty million new engines per year with annual earnings in trillions of dollars.

The multi dimensional nature of the world's internal combustion engine market makes the manufacturing of engines one of the world's largest and most dynamic industries.

In 1996 all engines manufacturers have one issue in common, "The Demand For Change", Environmental protection dominates. Engine manufacturers must now comply to the world's demand for stringently controlled emission standards and to develop engine technology in the future capable of meeting government regulations, as we progress towards and beyond the year 2001.

The unique OX2 engine has been hailed as the first real breakthrough technology in internal combustion engine design since the introduction of the Otto Four-Cycle Engine over 139 years ago. Preliminary studies have shown the OX2 engine will either meet or exceeds governmental and environmental requirements. The OX2 engine's technology can be appropriate from zero to multi-hundred horsepower engines - marine applications, generators, automotive, aircraft and industrial engine applications.

The engine has only six major components - of which only three are moving parts - and results in low set-up and production costs, and a simplicity of design that promotes a high level of quality assurance and lower maintenance costs.




Because the OX2 engine does not use a crankshaft, it has been able to achieve a leverage advantage over a conventional four-stroke engine with a similar stroke. The method used to achieve this unique efficiency is the subject of the engine's patent.


Combustion
The combustion chambers are only slightly longer than the stroke and pistons need only to be thick enough to house the rings. The OX2 contains no piston skirts and the rings are the only contact point with the bore. In effect, at no time do the pistons touch the bore, and nor are they reliant on it for support. This system eliminates loading on the sides of the combustion chambers.


Timing
Further, the OX2 engine design enables the timing to be adjusted sufficiently to produce the most effective burn of the combustible fuel being used - irrespective of the engine RPM. This highly efficient procedure is possible due to the extended dwell at the top of the compression stroke. Compare this to a conventional four-stroke engine where pre-ignition occurs if the timing is advanced too far, causing combustion prior to the top of the stroke. The result of such pre-ignition is resistance against the crankshaft, which causes a loss of energy.

Piston Speed
Further, the OX2 piston speed, which is controlled by the fuel burn rate, remains constant throughout the entire power stroke. The inlet and exhaust ports do not open until the exhaust and power strokes respectively have been fully completed. The ports then remain open long enough to ensure maximum operating efficiency. This process enables a more regulated mixture to be introduced prior to firing and also allows the significantly reduced exhaust gases to be expelled efficiently.

Torque
Another unique feature of the OX2 engine is that it achieves considerable torque at all stages through its operating range. Consequently, in most engine applications there would be no need for the engine to operate at revs higher than 2,500 rpm. In some instances, this would eliminate the need for a gearbox and would certainly reduce engine wear. However, in particular applications, if high engine revs were mandated, the OX2 engine could easily be adapted accordingly.

Single Port
In the OX2 engine, air and fuel are taken in to the combustion chamber through a single port located in the center of the combustion chamber. This port is adaptable and could be the size of the chamber if desired. In the OX2, the port is fully opened for the entire duration of the stroke plus some additional time to allow a full chamber of air and fuel mixture. There is no valve restricting the air/fuel mixture flow and the chamber is convex in shape so the cylinder fully charges with maximum efficiency. Since this single port is also the exhaust port, a heat transfer takes place on intake, cooling the port and seal, while maximizing fuel vaporization in the one simple process. In addition, exhaust gases are also recirculated into the combustion chamber on intake, further assisting in the vaporization of the fuel.

Exhaust
Another aspect of the OX2 engine is designed to have exhaust gases fed back in to the combustion chamber, ensuring that the engine pressure is only slightly below atmospheric pressure - eliminating the majority of the vacuum created. The design ensures that there is no waste of energy fighting vacuum and also allows for optimum compression regardless of the air/fuel delivery. Thus, more fuel is used driving the piston and less is wasted pressuring the combustion chamber. Because of the minute pressure differential, the air/fuel mixture induced in to the cylinder does not drop in temperature. When the heat of recirculated exhaust gases is added, the fuel remains in a gaseous form, thus ensuring an efficient burn from the OX2 engine.

<-- asi me kedo tras entender lo pokillo ke he podido...

ke posibilidades hay de aplicar este tipo de motor en un furuto proximo?

opinion personal, talonsport?

talonsport

como toda tecnologia nueva va a necesitar mucho tiempo para desterrar al todopoderoso ciclo OTTO pero ya esta el WANKEL y ahora este que parecen muy buenos la verdad que el WANKEL me encanta y cada dia es mas confiable y durable gracias a los nuevos materiales
pienso en unos 10 años el ciclo OTTO va a tener los dias contados
estos motores conbsiguen muy buenos rendiemientos con bajos consumos y emisiones asi que solo queda esperar
