An oil temperature control assembly mounts on a vehicle's operating group fluidically connected to an oil circulation system and a cooling system. A heat exchanger has plate-shaped exchanger elements defining reciprocally alternate ducts through which oil and refrigerant fluid flow, and a support and oil control device. The support and oil control device has a plate-shaped base element including the oil inlet and outlet ducts having a first surface in contact and engageable by the heat exchanger and a second opposite surface. The support and oil control device includes a control group having a housing body projecting from the first surface next to the heat exchanger having a housing cavity fluidically connected to the inlet and outlet ducts and an exchanger duct and a valve member in the housing cavity including an obturator element and a control element which moves the obturator element according to oil operating conditions.

A method of manufacturing a thermo valve includes an overlaying step of overlaying a valve body onto a thermo actuator so as to cover a groove portion; and a caulking step of caulking an installing portion of the valve body onto the thermo actuator. The caulking step is performed by pressing, by use of a jig, the valve body and the thermo actuator toward an axis center in a radial direction. A pressing face of the jig has a short side portion and a long side portion longer than the short side portion. Pressing is performed with the long side portion being substantially in parallel to the axis center of the thermo actuator and the short side portion being substantially in parallel to the groove portion.

An assembly includes a valve integration unit attached to a transmission oil heater. The valve integration unit includes a valve mechanism and a housing having first to sixth fluid ports for oil input and output. The interior space of the housing has a valve chamber to receive a thermal valve mechanism has a temperature responsive actuator. A bypass flow passage is located outside the heat exchanger and is in fluid communication with oil inlet and outlet manifolds through first and second bypass holes provided in the heat exchanger.

Disclosed is a thermostatic valve, including: a pressure relief ring capable of moving up and down and disposed in a valve body cavity. In normal conditions, the pressure relief ring is abutted against the outer edge of a first valve seat by means of a spring. An internal channel capable of being opened or closed by means of up and down movement of the pressure relief ring is further provided in the valve body cavity; when the pressure of a fluid in the thermostatic valve is excessive, the fluid can drive the pressure relief ring to compress the spring, such that the internal channel is in communication with a third interface to realize simultaneous communication with a first flow channel and a third flow channel, and thus damages caused by excessive pressure of the fluid in the temperature regulating valve can be prevented.

A heat exchange device, including a heat exchanger main body and a temperature regulation assembly; when the temperature of an oil that flows into a valve cavity is higher than or equal to a preset temperature, the elastic potential energy of a memory spring of the temperature regulation assembly is activated, and the oil enters a heat exchange channel for heat exchange; otherwise, the oil directly flows out of the heat exchanger main body by means of a bypass channel without passing through a heat dissipation assembly; the thermal reaction of the memory spring is fast and response time is short, greatly improving the operating performance and usage safety of a transmission; moreover, the memory spring is small in size, and has higher installation stability, while cooperative use with other parts is not necessary, thus simplifying the structure of the temperature regulation assembly.

A temperature responsive valve includes a housing and a cylindrical structure disposed within the housing. The housing defines an inlet passageway and an outlet passageway wherein the cylinder body of the cylindrical structure is disposed between the inlet passageway and the outlet passageway. The cylindrical structure includes a first layer so that the cylindrical structure is configured to expand from a decreased diameter to an increased diameter when the first layer of the cylindrical structure is exposed to an increased pre-determined temperature range causing the cylindrical structure restricts the inlet passageway and the outlet passageway at such increased pre-determined temperature range.

Methods and systems are provided for preemptively heating engine oil prior to an engine start using an inductive heating mat. In one example, a method may include coupling a magnetic field between a primary coil housed in the inductive heating mat and a ferrous oil pan to inductively heat engine oil contained in the oil pan. While maintaining engine oil temperature above a threshold temperature, heated engine oil may then be circulated through engine components to warm up the engine prior to engine start.

A method of reducing cold startup time of a genset includes providing a lubricant to the genset at predetermined time intervals before a genset startup. The lubricant is heated to a predetermined lubricant temperature using an external heating system. A high temperature coolant of the genset is heated to greater than a predetermined high temperature coolant temperature. The speed of the engine is ramped to a target speed continuously without pausing at a speed lower than the target speed. Genset electrical parameters of the genset are synchronized to utility grid or load electrical parameters of the utility grid or load. The genset is electrically coupled to the utility grid or load such that the synchronizing and electrically coupling are performed within a predetermined synchronization time. A fueling rate and a spark timing is adjusted based on a power being produced by the genset.

A hybrid intercooler system is provided to adjust an oil temperature. The system includes an air cooling unit that exchanges heat with external air passing through outer surfaces of a plurality of compressed intake air channels and cools compressed intake air passing through interiors of the compressed intake air channels. A water cooling unit exchanges heat between engine cooling water enclosing the outer surfaces of the compressed intake air channels and the compressed intake air passing through the interiors of the compressed intake air channels and cools the compressed intake air. Additionally, an oil temperature controller exchanges heat between oil and the engine cooling water that is heated by the heat exchange performed by the water cooling unit and adjusts the temperature of the oil.

An assembly includes a valve integration unit attached to a transmission oil heater. The valve integration unit includes a valve mechanism and a housing having first to sixth fluid ports for oil input and output. The interior space of the housing has three portions, including a second portion defining a valve chamber and a third portion defining a bypass flow passage between the first and second portions. The valve mechanism has a temperature responsive actuator and first, second and third valve elements. The movement of the first and second valve elements is actuated by the temperature responsive actuator. The third valve element and the third valve opening are located in the second portion of the interior space. The third valve element is actuatable in response to a pressure differential between the first and second portions of the interior space.
