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.

Control apparatus for internal combustion engine

Номер: US20170009727A1
Автор: Satoshi Nakamura
Принадлежит: Toyota Motor Corp

An ECU outputs an ignition signal and a discharge waveform control signal. An ignition device closes an ignition switching element in a period during which the ignition signal is input. After a stop of the input of the ignition signal and in a period of input of the discharge waveform control signal, the ignition device controls current flowing through a primary coil to a discharge current command value that is determined by the discharge waveform control signal by opening or closing a control switching element. A discharge control unit determines whether there is an abnormality. When it is determined that there is an abnormality, the ECU avoids control executed by the discharge control unit, and causes the discharge control unit to execute control during times of low-rotation and low-load operation of an internal combustion engine in order to determine whether the discharge control unit has returned to a normal state.

Active scavenge prechamber

Автор: Luigi P. Tozzi, Maria Emmanuella Sotiropoulou
Принадлежит: Prometheus Applied Technologies LLC

In certain embodiments with large size prechambers and/or with prechambers that have large spark-gap electrode assemblies, a poor scavenge of the crevice volume may cause deterioration of the preignition margin, which then may limit the power rating of the engine, may cause the flow velocity field of the fuel-air mixture to be excessively uneven and may result in the deterioration of the misfire limit. One or more auxiliary scavenging ports may allow admission of fuel rich mixture to the crevice volume, thereby cooling the residual gases and preventing occurrence of preignition. More organized and powerful flow velocity fields may be obtained in the spark-gap electrode assembly region. This condition may result in a significant extension of the flammability limit and may significantly improve the combustion efficiency of the prechamber. Passive prechambers using the active scavenge concept may increase the engine power output and reduce the emission of pollutants from engine combustion.

Автор: Philip C. MILLWARD, Roderick C.S. BEAZLEY, William D. Tenny
Принадлежит: Westport Power Inc

Diesel-cycle engines are known to have greater power, torque and efficiency compared to Otto-cycle engines of like displacement. When the fuel is a gaseous fuel, such as natural gas, a pilot fuel (such as diesel) is normally required to assist with ignition in a gaseous fuelled Diesel-cycle engine. It would be advantageous to reduce the power, torque and efficiency gap between a Diesel-cycle engine and a gaseous fuelled Otto-cycle engine. A combustion apparatus for a gaseous fuelled internal combustion engine comprises a combustion chamber defined by a cylinder bore, a cylinder head and a piston reciprocating within the cylinder bore. A diameter of the cylinder bore is at least 90 mm and a ratio between the diameter and a stroke length of the piston is at most 0.95. There is at least one intake passage for delivering a charge to the combustion chamber, and at least one intake valve is configured in the cylinder head and cooperates with the intake passage to create a predominant tumble flow motion in the combustion chamber.
