Подогрев топлива при холодном запуске бензинового двигателя с непосредственным впрыском топлива

Установлено, что бензиновые двигатели с непосредственным впрыском топлива выбрасывают твердые частицы на протяжении первых 500 секунд работы из-за топлива, ударяющегося о поверхности камеры сгорания. Для того чтобы значительно предотвратить попадание топлива на поверхности в камере сгорания, топливо можно подогревать. В одном варианте осуществления охлаждающая жидкость двигателя, которая нагревается в частях водяной рубашки, ближайших к выпускным каналам, подается непосредственно в трубку в физическом контакте с направляющей-распределителем для топлива. В некоторых вариантах осуществления трубка оснащена электрическим нагревательным элементом. Если в начальные части холодного запуска насос охлаждающей жидкости выключен, температуру топлива в направляющей-распределителе для топлива повышает электрический нагреватель. После того температура охлаждающей жидкости двигателя повышается, в трубку рядом с направляющей-распределителем для топлива подается вода, теплая охлаждающая жидкость, а нагреватель выключается.
