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.

A method of increasing internal combustion engine efficiency is based on using engine cooling air and exhaust gas by flowing this mixture into a convergent nozzle thus accelerating the gas mixture and eject it through nozzle exit, thus generating thrust in a desired direction which could push a land air or sea vehicle. Another option is to use the accelerated gas to drive a turbine that could add its torque to the engine or to drive electrical generator that produces electricity.

Structure of Exhaust Pipe for Exhaust Heat Recovery

Номер: US20140054008A1
Автор: Ki Chul Park
Принадлежит: Hyundai Motor Co

An exhaust pipe heats coolant with heat of exhaust gas. The structure of the exhaust pipe can increase heat exchange efficiency because a flow direction of the coolant is arranged to be opposite to a flow direction of the exhaust gas. The coolant can smoothly flow inside the housing, because density of the coolant decreases as the coolant is heated while flowing in a lower side of the housing and flowing out of an upper side of the housing. In addition, the heat transfer pipe of which one surface is in contact with the exhaust gas and the other side is in contact with the coolant has wrinkle portions which are formed on a surface of the heat transfer pipe, where heat exchange is performed, and thereby, a heat exchange area can be increased and the coolant can be more rapidly heated without increasing a size of the housing.
