  • Remarkable construction of the engine by Georgi Vassiljev

    Posted on March 4th, 2013 Mr. Leo Siemann No comments

    We know how electric cars were turned down in America in 1930s. We also know the reason why –  because of the boom in oil industry. As fossil energy is running out now We need more eco-engines and way more alternative energy to run our motobikes, cars & boats. But how to achieve that? Some have made it  already, but still a lot more progress needs to be done !

    Retired engineer Georgi Vassiljev from Tallinn has come up with the solution, which is so simple, fast & small that can well beat the existing 4-stroke engines by its power and also by the production cost ! From Today Georgi is searching for a manufacturing company, which could produce his engine in good quality and quantity. Therefore I have come to help Georgi to find this company and I have published a part of his patent (PCT) first, to get the attention of top-notch manufacturer. If you seize it as your opportunity for the further innovation and possible lead on the market, please contact to me very soon by email: leo@estonia100.com

    The International Searching Authority sent me a Search Report and Written Opinion on my International Application for “Two-cycle trunk-piston engine” that was sent to European Patent Office in Hague. 

    The contents of these documents allow me to introduce to interested parties both the design of the above mentioned engine (Fig. 1) as well as the design of two other engines the applications for which were sent to the Patent Office later (Fig. 2, Fig. 3 and Fig.4) before the phase of the national patenting.

      Fig. 1 depicts the engine at the moment exhaust gases free emission start from the cylinder 4, the transfer ports 3 are open, the exhaust gases from the cylinder 4 have flown to the plates of the return valve 6 and have closed the valve that prevents the exhaust gases flow from the cylinder 4 into the receiver 5. The further movement of the piston 1 opens the exhaust ports 2, the exhaust gases start emitting freely and as result, the exhaust gases pressure drops in the cylinder below air pressure in the receiver 5, valve 6 opens and the scavenging of the cylinder 4 starts until the exhaust ports 2 are closed by the retrogressive movement of the piston 1, following which until the closing of the transfer ports 3, the air from the receiver 5 would flow into the cylinder 4 and raise the air pressure in the cylinder.

     The gases interchange in the engine (Fig. 2) is analogous to the above described, the only difference being that from the moment of transfer ports 3 opening and until the pressure drop in the cylinder 4 below the pressure value in the receiver 5, the flow of exhaust gases from the cylinder to the receiver is prevented not by the return valve plate but by turning gate 7 that is cinematically connected with the crankshaft.

     Fig. 3 shows the engine at the moment when the pressure in the cylinder 4 during the free emission of the exhaust gases through the exhaust ports 2 dropped lower than the air pressure in the receiver 5. As the result of further movement of the piston 1, the transfer ports 3 are opening and the cylinder 4 starts scavenging by air from the receiver 5, that ends as the result of the piston retrogressive movement at the moment the exhaust ports 2 are closed by the turn gate 7 that is cinematically connected to the crankshaft (see drawing on Fig. 4) and then until the closing of the transfer ports 3 (see drawing on Fig. 5) the air from the receiver 5 will flow into the cylinder 4, raising the pressure in the cylinder.

    All engine models are equipped with external compressors.

    When comparing the areas of the exhaust ports 2 with the area of the exhaust ports of the high-speed racing two-cycle engines with the cylinder multichannel loop scavenging that have the power-weight ratio up to 400 horse powers per 1 litre of the cylinders’ work capacity, it is important to note that in case of the identical exhaust ports height, piston stroke and cylinder capacity of the compared engines, the patented engines’ models have the area of exhaust ports two times bigger and even exceed the area of the piston because their cylinder’s outer diameter is bigger and there is no need to locate transfer ports beside each other, thus enabling the higher speed of scavenging than in the engines of racing motorcycles.

    The high scavenging speed in the patented models together with internal carburetion and the boost through transfer ports give the possibility to develop, for example, a two-cylinder opposed engine with the cylinders’ work capacity of 0.8 litres, the performance of 250 horse powers and the cost several times lower than of a four-cycle engine of the same performance.

    * That seems to me well interesting, high-performing and cost-saving technical solution what Georgi has made. Please do not hesitate to contact to me if you are interested as we will execute the license for this patent (PCT) to one of the leading engine-manufacturers  in the World within next  month  or so.  PS. This unique patent is pending at WIPO and is not officially published yet … 

               Waiting for your kind offers,
