Abstract
Пневматический привод газораспределительного клапана двигателя внутреннего сгорания включает поршень привода газораспределительного клапана двигателя внутреннего сгорания, соединенный с газораспределительным клапаном двигателя внутреннего сгорания, газораспределитель, пневмоаккумулятор и систему управления пневматическим приводом и предназначается для обеспечения газообмена в двигателе внутреннего сгорания, для чего система управления пневматическим приводом отслеживает текущее положение поршня двигателя внутреннего сгорания и в момент, когда требуется открыть или закрыть газораспределительный клапан двигателя внутреннего сгорания, устанавливает газораспределитель в положение, обеспечивающее поступление рабочего тела из пневмоаккумулятора в ту полость поршня привода газораспределитнльного клапана двигателя внутреннего сгорания, в которой рабочее тело, воздействуя на поршень привода газораспределительного клапана двигателя внутреннего сгорания, открывает или закрывает газораспределительный клапан двигателя внутреннего сгорания, отличающийся тем, что зарядка пневмоаккумулятора рабочим телом осуществляется из камеры сгорания двигателя внутреннего сгорания при такте сжатия воздуха или топливной смеси в его цилиндре и прерывается клапаном-отсечкой до момента, когда температура сжимаемого воздуха или топливной смеси достигает температурного предела работоспособности материалов пневматического привода клапана газораспределительного клапана двигателя внутреннего сгорания.The pneumatic drive of a gas distribution valve of an internal combustion engine includes a piston of a drive of a gas distribution valve of an internal combustion engine connected to a gas distribution valve of an internal combustion engine, a gas distribution valve, an air accumulator and a pneumatic drive control system and is intended to provide gas exchange in an internal combustion engine, for which a pneumatic drive control system monitors the current internal combustion engine piston position and at the time when it is necessary to open or close the gas distribution valve of the internal combustion engine, sets the gas distribution valve in a position that ensures the working fluid from the pneumatic accumulator enters the piston cavity of the gas distribution valve of the internal combustion engine in which the working fluid acts on the piston of the gas distribution valve of the engine combustion engine, opens or closes the gas control valve of an internal combustion engine, characterized in that that the pneumatic accumulator is charged by the working fluid from the combustion chamber of the internal combustion engine during the compression stroke of air or the fuel mixture in its cylinder and is interrupted by the shut-off valve until the temperature of the compressed air or fuel mixture reaches the temperature limit of the working capacity of the materials of the pneumatic valve drive the gas distribution valve of the internal engine combustion.
