After pressurizing a low pressure fuel rail, a lift pump may be disabled and port injector variability may be correlated with a measured fuel rail pressure drop at each port injection event by sweeping injection pressure while maintaining injection voltage, and then sweeping injection voltage while maintaining injection pressure. A port injector variability map learned as a function of injection voltage and injection pressure is then transformed into a map learned as a function of injection current and injection pressure by accounting for injector variability caused due to changes in injector temperature.

Control device for in-vehicle internal combustion engine

A Vehicle-installed internal combustion engine control apparatus and method for maintaining a good operating condition of the internal combustion engine(12) even if the opportunity of control learning is limited is disclosed. To adjust the closed-state opening of a throttle valve(29), that is, opening of the throttle valve(29) under a non-load condition, feedback control of the opening of the throttle valve(29) is performed so that the idle speed approaches a target revolution speed, while the non-load idling of the engine(12) is being performed. A feedback correction amount for the feedback control is stored as a learned value. The learned correction value is reflected in the next and later operations of the closed-state opening control of the throttle valve(29), so that a proper closed-state opening of the throttle valve(29) is set. During the learning of the feedback correction amount, the engine(12) is inhibited from being stopped. <IMAGE>

Method of and device for calibrating of pressure transmitter

Изобретение относится к двигателестроению, в частности к способам и устройствам для калибровки датчиков давления системы дозирования топлива двигателя внутреннего сгорания. Изобретение позволяет минимизировать разность между опорным давлением и регистрируемым датчиком давлением. Способ калибровки датчика давления системы дозирования топлива двигателя внутреннего сгорания (ДВС) заключается в том, что в системе дозирования топлива имеются насос высокого давления, предназначенный для подачи топлива из области низкого давления (НД) в область высокого давления (ВД), форсунки, управляемые в зависимости от рабочих параметров и предназначенные для дозированной подачи топлива из области высокого давления (ВД) в камеры сгорания ДВС, и датчик давления, предназначенный для измерения давления в области высокого давления (ВД). Преобладающее в области высокого давления (ВД) давление принимают за эталонное или опорное давление. Преобладающее в области высокого давления (ВД) давление измеряют с помощью датчика давления как давление, регистрируемое этим датчиком, и определяют разность между опорным давлением и регистрируемым датчиком давлением. В области высокого давления (ВД) создают давление, для чего для создания давления в области низкого давления (НД) включают топливоподающий насос системы дозирования топлива, и это давление передают из области низкого давления (НД) в область высокого давления (ВД) и принимают его за опорное давление. Характеристику датчика давления корректируют таким образом, чтобы минимизировать разность между опорным давлением и регистрируемым датчиком давлением. Для осуществления способа используется устройство для калибровки датчика давления системы дозирования топлива, включающее средства, представленные в способе ДВС. 2 с. и 7 з.п. ф-лы. 2 ил.

Method and apparatus for operating internal combustion engine

Air-fuel ratio control device for internal combustion engine

Device for control for internal combustion engine with variable compression ratio

FIELD: engine building. SUBSTANCE: control device for the variable compression ratio internal combustion engine is provided with a variable compression ratio mechanism for varying the compression ratio of the engine in accordance with with the angular position of the control shaft and the compression ratio unit, which determines the actual compression ratio. In a predetermined state (S11) of the engine operation, such as immediately after starting the engine, the initial position learning operation for the compression ratio determination unit is performed (S12) with the control shaft mechanically locked in a predetermined initial position. During engine operation, even when the actual compression ratio is lost due to a communication error or the like (S13) or even when the difference between the actual compression ratio and the target compression ratio becomes greater than the allowable deviation due to some faults (S14), initial position learning operation is immediately executed (S15), thereby allowing a quick return to a state where normal control of the compression ratio can be performed. EFFECT: ability to quickly return to a state where normal control of the compression ratio can be performed. 7 cl, 3 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 656 072 C1 (51) МПК F02D 15/02 (2006.01) F02B 75/04 (2006.01) F02D 13/02 (2006.01) F02D 37/02 (2006.01) F02D 9/08 (2006.01) F02P 5/145 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F02B 75/045 (2018.02); F02D 13/0215 (2018.02); F02D 15/02 (2018.02); F02D 37/02 (2018.02); F02D 41/0002 (2018.02); F02D 41/22 (2018.02); F02D 41/2438 (2018.02); F02D 41/2441 (2018.02); F02D 41/2474 (2018.02); F02D 9/08 (2018.02); F02P 5/145 (2018.02); F02P 5/151 (2018.02) (21)(22) Заявка: 2017102324, 27.06.2014 27.06.2014 R U (24) Дата начала отсчета срока действия патента: (72) Автор(ы): ХИЙОСИ Риосуке (JP), ОХЦУ Се (JP) (73) Патентообладатель(и): НИССАН МОТОР КО., ЛТД.
