A thermostatic valve for an internal combustion engine, including a housing with a plurality of coolant connections for connection to a coolant circuit of the internal combustion engine, a valve element which is mounted movably in the housing such that a movement of the valve element, at least two coolant connections of the housing are either connectable to one another or separable from one another, an expansion element which is arranged in order, during the operation of the internal combustion engine, to enter into thermal contact with coolant circulating in the coolant circuit, wherein, in the event of a heat-induced expansion, the expansion element moves the valve element in the housing in order to connect the at least two coolant connections, wherein a controllable heating device is provided such that the expansion element can be heated in order to move the valve element.

An apparatus for controlling an engine and a method thereof are provided. The apparatus includes an integrated thermal management (ITM) that adjusts opening of a plurality of valves as a cam rotates and a storage that stores a table for differential pressure between a front end and a rear end of each of the plurality of valves, based on an engine revolution per minute (RPM) and an ITM angle. A controller determines a state of the ITM and adjusts opening degrees of the plurality of valves depending on the differential pressure of the valve, based on the differential pressure table based on the state of the ITM.

A control valve for a heat management module of a motor vehicle is provided, which includes a valve disk, a valve shaft connected to the valve disk; and a shaft bearing on which the valve shaft is mounted such that it can move axially from a bearing surface. The control valve further includes a radial spring biased radially towards the shaft bearing. A receiving groove of the valve shaft includes an inhibiting section and a free-running section that are axially separated by a clamping wedge,

The radial spring, in the region of the bearing surface is unable to overcome the clamping wedge and the radial spring is pressable radially by the clamping wedge such that the valve shaft is inhibited in the axial direction away from the free-running section.

A control position can be held in a continuous manner without energy in a small installation space.

A thermal management module comprises a housing and a drive shaft located within the housing. The housing is provided with a first internal cavity, a partition and a second internal cavity which are arranged in series along the axial direction of the drive shaft. The first internal cavity and the second internal cavity are separated by the partition. The partition is proved with a through-hole through which the drive shaft passes. One end of the drive shaft extends into the first internal cavity. A second internal cavity is used for receiving a drivetrain for rotating the drive shaft.

The present invention relates to a cooling system (1) of an internal-combustion engine. Cooling system (1) comprises a closed cooling loop and it includes a closed loop in a Rankine cycle allowing part of the coolant heat to be recovered. According to the invention, the cooling loop comprises two thermostats (6; 20) and evaporator (19) of the Rankine loop is arranged between the two thermostats (6; 20).

A cooling system may include a cylinder block; an exhaust gas recirculation (EGR) cooler that receives some of a coolant of the cylinder block and transmits the received coolant back to the cylinder block; a cylinder head that receives a coolant from the cylinder block; a thermal management module that selectively transmits the coolant received from the cylinder head to a plurality of coolant lines; a water pump that transmits the coolants transmitted from the plurality of coolant lines to the cylinder block; and a controller that is connected to the thermal management module and configured to control operation of the thermal management module.

A method includes: (a) determining an engine speed of an internal combustion engine, wherein the internal combustion engine has an engine wall, and the engine wall has a wall temperature; (b) determining an engine load of the internal combustion engine; (c) determining a wall-reference temperature as a function of the engine load and the engine speed of the internal combustion engine; and (d) adjusting, using a cooling system, a volumetric flow rate of a coolant flowing through the internal combustion engine to maintain the wall temperature at the wall-reference temperature.

Systems and methods are provided for determining a temperature of a thermal system that includes fluid conduits. A sensor monitors a current state of the temperature. A controller receives a signal from the sensor that is representative of the current state; determines a flow in the fluid conduits; determines a noise covariance of the thermal system; processes a thermal model of the thermal system; predicts a next-step state of the parameter at a time after the current state; and corrects the next-step state based, at least in-part, on the noise covariance resulting in a corrected next-step state.

A water pump of an engine cooling system includes a thermal valve that divides an outlet space of a pump housing of an outlet port, through which the engine coolant pumped into the internal space of a pump housing is discharged, into a front end discharge region and a rear end discharge region. The thermal valve also forms a dual flow path through which the engine coolant is discharged to the front end discharge region and the rear end discharge region according to the increase of the coolant temperature. The cooling of a cylinder block and a cylinder head of an engine are thus separately adjusted.
