A valve includes a body having an interior and defining at least one inlet passageway and discharge passageway. The valve also includes a flow diverter disposed within the body between the inlet and discharge passageways to receive a fluid from the inlet passageway in an inlet direction. The diverter is adapted to discharge the fluid to at least one discharge passageway in a direction that differs from the inlet direction. The diverter is rotatable to vary the discharge direction. According to one embodiment, the discharge direction is substantially perpendicular to the inlet direction. In another embodiment, a series of fluid passages are formed between the diverter and the interior of the valve body to permit a small firm or thickness of fluid to extend between portions of the diverter and the valve body, thereby forming a fluid bearing.

A vehicle thermal management system includes an exhaust gas cooler configured to receive exhaust gas from the engine and to cool the exhaust gas before it is recirculated back into the engine. A valve is located downstream from the exhaust gas cooler, and is operable to control the amount of exhaust gas passing through the exhaust gas cooler. Intake air mixes with the exhaust gas downstream from the first valve. The mixed gas is then cooled by a mixed gas cooler before it enters the engine intake manifold. A coolant is circulated through the mixed gas cooler and a heat exchanger. The mixed gas rejects heat to the coolant via the mixed gas cooler, and the coolant rejects heat to the ambient air via the heat exchanger.

A temperature control system in a liquid cooled internal combustion engine including an electronically assisted thermostat for controlling flow of a temperature control fluid through the engine. The electronically assisted thermostat has a first state for inhibiting said flow and a second state for allowing said flow. The thermostat includes a housing with a valve member that reciprocates within the housing between the first state and the second state. A return spring biases the valve member into the second state. A wax pellet is attached to the valve member and has a solid state and a liquid state. The wax pellet maintains the valve member in its first state when the wax pellet is in its solid state, and allows the return spring to bias the valve member into its second state when the wax pellet is in its liquid state. A heating element is mounted within the housing and adapted to transfer heat to wax pellet. The heating element is adapted to receive an electrical transmission for producing heating of the heating element. An engine computer determines a thermostat state based on the temperature control fluid temperature signal and the additional signal. The engine computer sends an output signal when the additional signal is above a predetermined value regardless of whether the temperature of the temperature in control fluid signal is below a predetermined temperature control fluid temperature value. The signal from the engine computer controls the electrical transmission to the heating element.

Electronically assisted thermostat for controlling engine temperature

A system for displaying engine temperature information for a temperature control system in an internal combustion engine. A first temperature sensor senses the temperature of ambient air. A second temperature sensor senses the temperature of an engine oil. A third temperature sensor senses the temperature of a temperature control fluid. The sensors provide signals indicative of the sensed temperatures to an engine computer. The engine computer compares the sensed ambient air temperature to a first set of predetermined values to determine a desired engine oil temperature. The engine computer also compares the sensed ambient air temperature to a second set of predetermined values to determine a desired temperature control fluid temperature. A signal indicative of the desired engine oil temperature and/or the desired temperature control fluid temperature is output from the engine computer to a display system. The display system displays the desired and the sensed temperature signals. The display system may be incorporated into the instrument panel of a vehicle. Alternately the display system may be part of a testing apparatus for testing the operational state of the temperature control system. One or more gauges may be incorporated into the display for accurately displaying the desired and sensed temperatures.

Free-flow buoyancy check valve for controlling flow of temperature

A temperature control system, in a liquid cooled internal combustion engine equipped with a radiator, controls the state of a flow control valve for controlling flow of a temperature control fluid through a passageway leading to the radiator. Sensors detect the engine operation temperature, the temperature of the temperature control fluid, t1, and the ambient air temperature, t2. An engine computer receives signals from the sensors, produces control signals based on both of the sensor signals, and sends the control signals to the flow control valve to control the state of the valve. The values t1 and t2 define a plurality of mathematical functions of t1=f(t2) which form a plurality of two-dimensional curves on an orthogonal coordinate system having axes t1 and t2. Each of the curves divide the coordinate system into two regions, one on either side of the curve. The engine computer control signals prevent flow through the valve when coordinate pairs of t1 and t2 lie on a first region of the coordinate system and allow the flow when coordinate pairs of t1 and t2 lie on a second region of the coordinate system. The engine computer receives a measurement of the actual engine operational temperature, compares it to an optimum engine operation temperature, and selects an appropriate curve based on the comparison.

System for controlling the state of a flow control valve

A temperature control system, in a liquid cooled internal combustion engine equipped with a radiator, controls the state of a flow control valve for controlling flow of a temperature control fluid through a passageway in the engine. Sensors detect the engine oil temperature and the temperature of the temperature control fluid. An engine computer receives signals from the sensors and compares the signals to one or more predetermined values. In one embodiment, the engine computer compares the engine oil temperature signal to a predetermined value to control actuation of the valve. In another embodiment, the engine computer compares the engine oil temperature signal to a predetermined engine oil temperature value. The engine computer adjusts a predetermined temperature control fluid temperature value based on the comparison of the engine oil temperature signal to the predetermined engine oil temperature value. The engine computer then compares the temperature control fluid temperature signal to the adjusted temperature control fluid temperature. The engine computer actuates the flow control valve based on the comparison of the temperature control fluid temperature signal to the adjusted temperature control fluid temperature.

System for maintaining engine oil at a desired temperature

A temperature control system in an internal combustion engine includes a heating arrangement which channels a flow of temperature control fluid from an engine to and from a heat exchanger used to preheat intake air flowing to an engine intake manifold when the ambient air temperature is relatively cold (e.g., below 20.degree. F.). In one embodiment, the heat exchanger is mounted upstream from a throttle body. The heat exchanger consists of a panel of high capacity heat transferring fins, which are heated by heat conductive tubes wrapped around the periphery of the panel. Flow of temperature control fluid to and from the heat exchanger is regulated by a control valve which is controlled by an engine computer unit in accordance with a set of predetermined values which define a curve that is a function of engine oil temperature and ambient air temperature.
