Abstract

Способ работы высокооборотного двигателя внутреннего сгорания, включающий подачу воздуха в рабочий цилиндр через воздуховпускной клапан и газа в форкамеру через газовпускной клапан после закрытия воздуховпускного клапана, перепуск газа в рабочий цилиндр, образование в рабочем цилиндре газовоздушной смеси с частичным ее перепуском в форкамеру через перепускной канал, сжатие газовоздушной смеси в рабочем цилиндре и в форкамере, воспламенение газовоздушной смеси в форкамере от искры свечи зажигания при нахождении поршня вблизи верхней мертвой точки, выброс горящей смеси из форкамеры в рабочий цилиндр через перепускной канал и ее сгорание, расширение продуктов сгорания в рабочем цилиндре и совершение механической работы, выпуск отработанных газов через выпускной клапан, отличающийся тем, что подачу газа в форкамеру начинают после прекращения подачи воздуха в рабочий цилиндр и завершают до момента достижения давления сжатия в рабочем цилиндре, превышающего давление газа, подаваемого в форкамеру, при этом перепуск газа в рабочий цилиндр осуществляют из форкамеры через перепускной канал.A method of operation of a high-speed internal combustion engine, including supplying air to the working cylinder through the air inlet valve and gas to the prechamber through the gas inlet valve after closing the air inlet valve, bypassing the gas into the working cylinder, forming a gas-air mixture in the working cylinder with its partial bypass to the prechamber through the bypass channel, compression of the gas-air mixture in the working cylinder and in the prechamber, ignition of the gas-air mixture in the prechamber from the spark of the spark plug when the piston is near the top dead center, ejection of the burning mixture from the prechamber into the working cylinder through the bypass channel and its combustion, expansion of combustion products in the working cylinder and mechanical work, the release of exhaust gases through the exhaust valve, characterized in that the gas supply to the prechamber begins after the cessation of air supply to the working cylinder and ends before the compression pressure in the working cylinder exceeds the pressure of the gas supplied to the fork measure, while the gas bypass into the working cylinder is carried out from the prechamber through the bypass channel.

Claims

The method of operation of a high-speed internal combustion engine, comprising supplying air to the working cylinder through the air inlet valve and gas to the pre-chamber through the gas inlet valve after closing the air inlet valve, bypassing gas into the working cylinder, forming an air-gas mixture in the working cylinder with its partial transfer to the pre-chamber through the bypass channel, compression of the gas-air mixture in the working cylinder and in the prechamber, ignition of the gas-air mixture in the prechamber from the spark of the spark plug when the piston is near the top dead point, the ejection of the burning mixture from the prechamber into the working cylinder through the bypass channel and its combustion, the expansion of the combustion products in the working cylinder and mechanical work, the release of exhaust gases through the exhaust valve, characterized in that the gas supply to the prechamber starts after the air supply to the working cylinder and complete until the compression pressure in the working cylinder exceeds the pressure of the gas supplied to the prechamber, while the gas is bypassed to the working cylinder from the prechamber passageway.
