Подогрев топлива при холодном запуске бензинового двигателя с непосредственным впрыском топлива

Номер: RU0000125633U1

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.

Coolant-to-Catalyst Fuel Modification Method and Apparatus

Номер: US20120138024A1
Автор: Scott Edward Taucher
Принадлежит: Scott Edward Taucher

A catalytic apparatus for efficient pre-combustion refinement of fossil fuel in vehicular engines, including an elongated outer metal pipe containing an elongated stainless steel inner tube of smaller diameter. The outer pipe is crimped or welded onto the inner tube to create a fuel chamber with connectors for the inflow and outflow of fossil fuel therethrough. The fuel chamber contains at least three catalytic elements each comprised of a different metal selected from the group Au, Cu, Ir, Ni, Pd, Pt, Zn and platiniridium, which may be electroplated small-pore screens. As engine coolant is diverted through the inner tube, excess heat is transferred to the inflowing fuel. The fuel is forced to flow in close proximity to the inner tube for maximum convection, and through the catalytic elements before flowing out through the fuel line to the fuel injectors for more efficient combustion. Also disclosed is a method of pre-combustion fuel refinement consisting of the steps of transferring excess heat from engine coolant through a tube disposed through an inlet and outlet of a fuel chamber. In the chamber the heated fossil fuel is forced through the catalytic elements described before returning to the fuel line for injection and combustion.

A cooling package for a vehicle, such as an agricultural tractor, having a charge air cooler assembly configured such that airflow is routed through a charge air cooler multiple times in order to cool a compressed charge of air. As the temperature rise experienced by the cooling airflow is relatively minor compared to the initial temperature of the compressed charge of air, the airflow is initially routed through an outlet-side portion of the charge air cooler to cool the compressed charge of air towards the outlet side of the charge air cooler, and subsequently routed through an inlet-side portion of the charge air cooler to cool the compressed charge of air towards the inlet side of the charge air cooler.
