Система подачи и зажигания топлива двухтактного газового двигателя с противоположно движущимися поршнями

Номер: RU0000206492U1

Полезная модель относится к системам питания газообразным топливом двухтактных двигателей внутреннего сгорания с противоположно движущимися поршнями. Может быть использована в газовых двигателях внутреннего сгорания стационарного и транспортного назначения. Задачей полезной модели является упрощение конструкции и повышение эффективности двигателя путем обеспечения рациональной подачи и более полного сгорания топлива. Задача решается за счет того, что форкамера со свечой зажигания встроена в переходник клапана-форсунки, установленного в резьбовое отверстие гильзы цилиндра, и через сопловые отверстия соединена с полостью гильзы цилиндра. Система подачи топлива двухтактного газового двигателя содержит гильзу цилиндра 1, с противоположно движущимися поршнями 3 и 4, окна для впуска воздуха 5 и выпуска отработавших газов 6, два резьбовых отверстия 2, диаметрально противоположно расположенных в средней части гильзы цилиндра, газовпускной клапан-форсунку 7 с форкамерой 8, встроенной в переходник 10, с резьбовой нарезкой и сопловыми отверстиями, установленный в резьбовое отверстие гильзы цилиндра. После сжатия газовоздушной смеси поршнями в гильзе цилиндра, часть газовоздушной смеси поступает в форкамеру 8, образуя в ней обогащенную смесь газа с воздухом, которая воспламеняется свечой зажигания 9 с выбросом в камеру сгорания гильзы цилиндра факела, поджигающего находящуюся в гильзе цилиндра смесь. Технический результат от использования полезной модели заключается в улучшении процесса смесеобразования газа с воздухом и, как следствие, в упрощении его зажигания и в более полном сгорании, а также в упрощении конструкции. 1 з.п. ф-лы, 2 ил.

A unit fuel injector ( 30 ) has a nozzle ( 36 ) providing axial guidance of a needle ( 72 ) at points proximal and distal to a needle feed cavity ( 81 ). The needle has a multi-lobular formation ( 200 ) providing distal guidance of the needle while allowing fuel from the needle feed cavity to flow past for injection from orifices ( 86 ) when the needle is unseated from a seat on a tapering surface ( 82 ). Fuel is delivered to the needle feed cavity through a slant passage ( 85 ) in the nozzle non-parallel to a longitudinal axis (AX) along which the needle is displaced. The orifices are arranged in a hemispherically contoured surface ( 83 ) distal to the seat and centered on a point on the longitudinal axis. The orifices have circular transverse cross sections. The axis of each orifice extends radially of the point on the longitudinal axis at an oblique angle to the longitudinal axis.

An in-cylinder pressure detecting device of a direct injection type internal combustion engine is provided in which a ring-shaped pressure detection element ( 34 ) surrounding a fuel injection hole ( 33 b ) is provided in the vicinity of an extremity of an injector ( 20 ) that injects fuel into a combustion chamber. Since the pressure detection element is provided on the injector, not only is it unnecessary to change the shape or structure of the cylinder head or the combustion chamber in order to provide the pressure detection element, but it is also possible to cool the pressure detection element ( 34 ) by fuel passing through the inside of the injector to thus enhance the precision of pressure detection and the durability. Further, since the ring-shaped pressure detection element ( 34 ) surrounds the periphery of the fuel injection hole ( 33 b ), it is possible to maximize the dimensions of the pressure detection element ( 34 ) to thus further enhance the precision of pressure detection while avoiding interference between the pressure detection element ( 34 ) and fuel injected via the fuel injection hole ( 33 b ).

A heated fuel injector for supplying fuel to a fuel consuming device includes a fuel inlet for receiving fuel, a fuel outlet for dispensing fuel from the fuel injector, and a fuel injector body extending along an axis and fluidly connecting the fuel inlet to the fuel outlet such that fuel flows within the injector body. A cylindrical heating element radially surrounds the fuel injector body and operates to heat fuel flowing through the fuel injector body. An annular space is defined between the heating element and the fuel injector body sufficiently large to accommodate thermally caused radial differential expansion between the fuel injector body and the heating element. A conductive material fills the annular space and has a melting point sufficiently low to be a liquid as the heating element operates to thereby substantially prevent transfer of mechanical stress to the heating element due to the radial differential expansion. 1.
