Abstract
(EN)
FIELD: engines and pumps. SUBSTANCE: engine electronic control unit executes program allowing computation of following magnitudes, i.e. fuel injection ratios of the injector fitted in the cylinder (S100), ignition advance with the help of the first card used when the injector fitted inside the cylinder features the fuel injection ratio equals 1. Note here that the first card ensures ignition the (S220), ignition advance with the help of the second card used for the fuel injection ratio that equals zero. Note that the second card ensures ignition time with the minimum advance (S230) and ignition advance with the help of the third card used for fuel injection ratio exceeding zero but smaller than unity. Note that the third card ensures ignition time with higher ignition advance for larger value of ratio (S240). EFFECT: control device for ICE comprising first and second fuel injection mechanisms participating together in injecting fuel into cylinder and intake manifold and allowing accurate computation of ignition time. 5 cl, 5 dwg

Изобретение относится к устройствам управления для двигателей внутреннего сгорания. Электронный блок управления двигателя выполняет программу, согласно которой осуществляется: расчет отношения впрыска топлива инжектора, установленного в цилиндре (S100); расчет величины опережения зажигания с использованием первой карты, применяемой, когда инжектор, установленный в цилиндре, имеет соотношение впрыска топлива, равное единице, причем первая карта обеспечивает время зажигания с максимальной величиной опережения (S220); расчет величины опережения зажигания с использованием второй карты, применяемой для соотношения впрыска топлива, равного нулю, причем вторая карта обеспечивает время зажигания с минимальной величиной опережения зажигания (S230); и расчет величины опережения зажигания с использованием третьей карты, применяемой для соотношения впрыска топлива больше чем ноль и меньше чем единица, причем третья карта обеспечивает время зажигания с большей величиной опережения зажигания для большего значения отношения (S240). Техническим результатом является создание устройства управления для двигателя внутреннего сгорания, имеющего первый и второй механизмы впрыска топлива, которые совместно участвуют во впрыске топлива в цилиндр и во впускной коллектор соответственно, которое способно точно рассчитать момент времени зажигания. 4 н. и 14 з.п. ф-лы, 9 ил.
