Beschreibung
Zusammenfassung:	FIELD: engines and pumps.SUBSTANCE: present invention relates to starting internal combustion engines with direct injection. Invention includes the following: in response to an indication of high pressure fuel pump degradation, fuel may be injected during an intake stroke, rather than a compression stroke, for a selected number of combustion events since the engine restart. By shifting to an intake stroke injection, the engine may be started even when sufficient fuel rail pressures are not available.EFFECT: to increase the reliability of starting a cold engine.10 cl, 6 dwg Изобретение относится к области запуска двигателей внутреннего сгорания с непосредственным впрыском. Техническим результатом является повышение надежности пуска холодного двигателя. Сущность изобретения заключается в том, что в ответ на указание ухудшения характеристик топливного насоса высокого давления при запуске двигателя топливо может впрыскиваться в течение такта впуска, а не такта сжатия на протяжении выбранного количества событий сгорания после перезапуска двигателя. Посредством переключения на впрыск в такте впуска двигатель может запускаться, даже когда нет в распоряжении достаточного давления топлива. 2 н. и 8 з.п. ф-лы, 6 ил.
