Biography
After graduating from St. Petersburg Technological Institute of Emperor Nicholas I worked at various engineering plants, especially for a long time at the Kolomensky Zavod as chief engineer.
Scientific activity
He created several original types of marine engines, including a two-stroke engine with counter-movement of pistons and synchronization of crankshafts through a system of gears. There is also another name for this type of engine - an engine with opposite-moving pistons (an engine with a PDP) .
On November 6, 1907, the engine was patented in France, then it was demonstrated at a number of international exhibitions. After these demonstrations, G. Junkers and, according to Junkers' drawings, Nobel factories, including in St. Petersburg, began to produce similar engines. The complaint filed by Koreyvo was not even considered, since A.Meshchersky, the managing director of the Kolomensky Zavod, prevented this from quarreling with influential foreigners. In the Soviet Union, diesels of such a system began to be used after meeting with Junkers Jumo 205 aviation diesels. How American Fairbanks-Morse diesel engines adapted to the USSR on military boats delivered under Lend-Lease adapted how the most massive series of diesel diesel engines 2D100 ( diesel locomotive TE3 ) and 10D100 (family diesel locomotives TE10 ) were created. Tank engines Plant them. Malysheva 5TD and 6TD are built directly according to the Koreyvo scheme.
In 1907 he created the project of the towing ship “Thought” with the transfer of power from the engine to the propeller wheels through the Korevo clutch . According to this project, powerful river ships (Petronius, Philosopher Plato, etc.) were subsequently built.
The Korevo clutch made it possible to transfer power from two engines to the propeller shaft with the elimination of torsional vibrations of the gear shafts and to reverse the wheels.
In 1908-1914, about 20 sea and river ships of the original design were built according to Koreyvo's projects.
