My name is Ardis Minassian and I am looking for support for my application for a patent under No.102363 of 1 April 1998 with the Bulgarian Patent Office. It is about a linkage mechanism, which optimizes the cinematic of the internal combustion engine with regard to each stroke. 

My calculations have shown that it is possible to achieve a 20-30% increase in the power of the engines using petrol and at the same time decrease pollution. In my opinion this patent will be used in the near future in most engines of the world. However, I haven’t got the financial means to develop my invention. So, I am looking for financing. 

I would like to make a business proposal to you - to buy a part of my rights under this patent for the opportunity to further develop the patent. 

Please contact me, if you are interested in it.

Description of the patent There remain some exhaust gases at the end of the exhaust stroke in the combustion chamber of an internal combustion engine and this makes it impossible to use the full volume of the cylinder at the intake stroke. There are two contradictory requirements to the definition of minimal combustion chamber volume. The first one is that it is not appropriate to compress the air-fuel mixture very much because of its self-ignition and the second is the craving to minimize the exhaust gases quantity in the cylinder.  This invention aims to enable to have all exhaust gases completely removed from the combustion chamber by varying the positions of the piston’s Top Death Center at the end of the compression and exhaust strokes.    Detailed description of the preferred embodiment The preferred embodiment mainly comprises a crankshaft 1 (figure 1), crank pin 2 with pinion 3, eccentric 4, connecting rod 5, piston 6, gear 7, auxiliary shaft 8, guiding hole 9, gear 10, chain transmission 11 (not shown), gear 12 and linking rod 13.

 
• Principle of action

With reference to figure 2 the intake stroke is from position 0º (720º) to 180º, followed by the compression stroke which takes place from position 180º to 360º, and after that by the power stroke from position 360º to 540º At the end is the exhaust stroke from position 540º to 720º (0º). Because of the hard cinematic link: piston 6 – connecting rod 5 – eccentric 4 – crankshaft 1, the crankshaft 1 turns around. The driving mechanism consisted of pinion 3 – gear 7 – additional crankshaft 8 – guiding hole 9 – gear 10 – chain 11 – gear 12 – eccentric 4 transforms the relative rotation of  connecting rod 5 against the crankshaft arm into a rotative movement of eccentric 4 around the crank pin 2. The gear ratio of the whole transforming system ensures one revolution of eccentric 4 at every two crankshaft revolutions.  The distance between piston 6 and crank pin 2 changes, because of the eccentricity “e” of mounting eccentric 4 to crank pin 2 and the rotary movement of  eccentric 4 against crank pin 2. This provides for two different TDC positions with distance between them 2”e”. 

As shown on Fig.2, at the end of the exhaust stroke – position 720º – piston 6 takes position TDC1 at a distance 2”e” from TDC2 on the cylinder’s axe. At the end of the exhaust stroke the volume of the combustion chamber is zero and the whole quantity of the exhaust gases is expelled from the cylinder.
