摘要： One or more techniques and/or systems are disclosed for a new coolant tank that may also provide a structural element to the frame of the engine compartment. The coolant tank is comprised of a rear wall that also makes up a portion of the firewall in the engine compartment. A structural coolant tank component is engaged with the rear wall to form the coolant reservoir. The coolant reservoir can provide support to attach structural elements of the vehicle, and can also allow for improved space efficiency in the engine compartment. Further, improved access to the filling port is provided, while continued operation and desired function is maintained even at extreme vehicle tilt.

摘要： A cooling system for internal combustion engines provides directed flows of heated or cooled coolant to various engine components and/or accessories as needed. By providing directed flows, the overall coolant flow volume is reduced from that of conventional cooling systems, allowing for a smaller capacity water pump to be employed which results in a net energy savings for the engine. Further, by reducing the overall coolant flow volume, the hoses and/or galleries required for the directed flows are reduced from those of conventional cooling systems, providing a cost savings and a weight savings. Finally, by preferably employing an impellor type water pump, the expense of an electric water pump and its associated control circuitry can be avoided. The direct flows are established by a multifunction valve which, in a preferred implementation, comprises a two-plate valve wherein each plate is operated by a wax motor.

摘要翻译： 用于内燃机的冷却系统根据需要向各种发动机部件和/或附件提供加热或冷却的冷却剂的指向流。 通过提供定向流动，整体冷却剂流量从常规冷却系统的流量减小，允许使用较小容量的水泵，这导致发动机的净能量节省。 此外，通过减少总体冷却剂流量，导向流所需的软管和/或画廊比常规冷却系统的软管和/或画廊减少，从而节省成本并减轻重量。 最后，通过优选采用叶轮式水泵，可以避免电动水泵及其相应的控制电路的费用。 直流是由多功能阀确定的，该多功能阀在优选的实施方式中包括一个双板阀，其中每个板由蜡马达操作。

摘要： A cooling apparatus that cools with coolant a subject of cooling, which is a heat source. The cooling apparatus includes a cooling circuit, an electric pump, a switching section, and a control section. Through circulation of the coolant, air in the cooing circuit is caused to flow to an air bleeding portion and is discharged from the cooling circuit through the air bleeding portion. The switching section is capable of switching the operation mode of the electric pump between a normal mode and an air bleeding mode for collecting air in the cooling circuit to the air bleeding portion. During the air bleeding mode, the control section is capable of controlling the electric pump to change a coolant displacement from the electric pump according to a change pattern that allows stagnant air in sections of the cooling circuit to flow to the air bleeding portion.

摘要： An engine cooling water passage structure includes a cooling water passage unit that is formed by integrating a water pump for supplying cooling water, a thermostat housing for housing a thermostat, a gas/liquid separation chamber for separating air from the cooling water, cooling water supply passages for supplying to water jackets, via the thermostat housing and the water pump, the cooling water that has been returned from a radiator, cooling water discharge passage for discharging into the radiator the cooling water that has passed through the water jackets, and a bypass passage for returning to the thermostat housing the cooling water that has passed through the water jackets, while bypassing the radiator. This cooling water passage unit is detachably mounted as a unit on an engine main body. Thus, the arrangement allows the engine cooling system to be made compact.
