The present invention relates to a vehicle oil warmer and a heat exchange system. More particularly, the present invention relates to a vehicle oil warmer and a heat exchange system, which enable a heat exchange between a coolant and oil to be automatically controlled according to the temperature of the coolant discharged from an engine, without a separate bypass valve for controlling the flow rate of the coolant, to thereby secure a heating performance of the vehicle interior while simultaneously heating the oil at the time of an initial start of the engine, and when the vehicle is running, lower the temperature of the oil by using an oil cooler in which low-temperature coolant flows, so that the temperature of the oil can be adjusted appropriately.

Various embodiments include a method for determining the temperature of an engine oil in an internal combustion engine comprising: acquiring a value of a parameter characterizing a current operating point of the internal combustion engine; and calculating the temperature of the engine oil using an oil temperature model. The oil temperature model depends at least in part on dilution of the engine oil caused by different components in the engine oil and accounts for modified heating behavior of the engine oil based on the dilution.

An oil temperature regulator assembly fluidly connects to both an oil circulation system and a cooling system of an operating group of a vehicle. The oil temperature regulator assembly includes a beat exchanger including an upper exchanger plate, intermediate exchanger plates, and a lower exchanger plate. The stacking of the plates defines an oil flow zone and a cooling fluid flow zone including, planar oil flow regions and planar fluid flow regions alternating with each other along the vertical axis and including, respectively, vertical oil ducts and vertical fluid ducts fluidly connected to respective planar flow regions. The oil temperature regulator assembly includes a base device engaged to the lower exchanger plate. The upper exchanger plate or base device includes an operating opening vertically aligned with a vertical oil duct. The oil temperature regulator assembly includes a filtering cartridge insertable through an operating opening in the vertical oil duct.

An apparatus for controlling the temperature of an oil cooler in a motor vehicle may include a temperature control arrangement. The temperature control arrangement may have a cold thermostat with a limit operating temperature and a warm thermostat with a lower limit operating temperature, the warm thermostat being connected in a fluid-connecting manner to the cold thermostat. The temperature control arrangement may also include a cold inlet for a coolant at a first temperature and a warm inlet for a coolant at a second temperature, the first temperature being lower than the second temperature. The temperature control arrangement may further include a coolant outlet fixable in a fluid-conducting manner to a coolant inlet of the oil cooler.

This oil pressure control device is provided with: an oil cooler which cools engine oil circulating through a hydraulic circuit of an engine; a bypass oil passage which bypasses the oil cooler; an oil cooler bypass valve by means of which an engine oil flow passage is switched between the oil cooler and the bypass oil passage; an oil pressure sensor which measures a first oil pressure, which is the oil pressure of engine oil; and a valve control unit which controls opening and closing of the oil cooler bypass valve to reduce the magnitude of a difference between the first oil pressure and a second oil pressure, which is a target oil pressure determined on the basis of the rotational speed of the engine and a fuel injection quantity.
