摘要： A method of operating an engine during an over temperature condition to protect the engine, an information recording medium incorporating a computer program implementing this protection method, and an electronic control module that performs this protection method are disclosed. A torque value representative of an engine generated torque is recorded in response to an engine temperature exceeding a protection temperature threshold. The engine torque is then reduced as a nonlinear function of the temperature signal and the recorded torque value to promote engine cooling.

摘要： An electronic control unit (ECU) of an engine system starts a control (preheat) that supplies heat reserving hot water stored in a heat accumulating device to an engine prior to an engine start. The ECU determines a time that continues the preheat on the basis of a cooling water temperature of the engine so as to execute the engine start after a warming-up of the engine is reliably finished. Further, during the execution of the preheat, a lighting lamp is turned on, and that incidence is recognized to a driver. When the preheat is completed, the ECU automatically starts the engine.

摘要： An electronic detection system monitoring coolant level and/or temperature of an internal combustion engine. A unit installed within the cab of a vehicle provides visual and audible warning if engine temperature rises above its normal hottest operating temperature and/or when coolant level drops below a selected level in the coolant reserve tank thereby preventing damage caused by overheating. The overheat detection system may comprise a heat sensor within a bolt which may be screwed directly into the engine head. An additional heat sensor positioned in the bottom radiator hose can be used in series with the engine head sensor. Associated circuitry is adjustable when installed to provide alarm activation when the temperature is a few degrees above the hottest normal engine operating temperature. If the engine starts to overheat, an LED lights up and an audible alarm sounds. A coolant level detector detects a drop in coolant level and comprises two probes installed horizontally in a side wall of the coolant reserve tank to provide a current path through the coolant present between the probes. Circuitry includes an appropriate timing means connected to the probes, and an LED indicator and/or audible alarm to warn the driver when the coolant level drops below a predetermined level. Additional coolant probes may be installed in the top radiator hose to warn the driver in the event of complete loss of coolant.

摘要： A valve is employed to control the flow of temperature control fluid to a radiator in an internal combustion engine. The valve is hydraulically actuated by a pair of hydraulic fluid injectors to move between a first position for preventing the flow to a second position for allowing the flow. The valve reciprocates within a valve housing. The fluid injectors cause pressurized hydraulic fluid to be delivered to and removed from a chamber in the valve housing. The fluid pressure in the chamber pushes against a valve diaphragm or piston to cause the diaphragm or piston to move from a first state to a second state, thereby causing a valve member or valve piston shaft to move from the first position to the second position. The valve can also control the flow of temperature control fluid through the oil pan and around the intake manifold.

摘要： A method for monitoring the health of a physical system that produces waste heat as a function of ambient temperature includes the generation of a standard profile model of the system in good health and a degraded profile model of the system in bad health, each profile being within the same family of curves. The monitored system is then sampled for sample ambient temperature and sample waste heat temperature to generate a system degradation indicator, preferably as a percentage of degradation. Alarms and displays present relevant warnings and information to the user. Waste heat affecting variables in addition to ambient temperature may be included in the standard and degraded profiles, and these variables may be monitored to produce the degradation indicator. The method is preferably microprocessor controlled.

摘要： When the driving wind and the cooling wind are generated, based on the phenomenon in which the temperature difference is generated between the front surface and the rear surface of the radiator (14), the temperature difference between the detection value of the rear temperature sensor (22) and the detection value of the front temperature sensor (21) is compared with the abnormality determination value so that it is determined whether the front temperature sensor (21) and the rear temperature sensor (22) are properly fixed on the radiator (14), whereby it is determined whether the abnormality (unauthorized alteration) exists. By setting the abnormality determination value according to the ambient temperature and the vehicle speed, corresponding to a variation in temperature difference between the front surface and the rear surface of the radiator (14), the abnormality determination value is varied to be set at a proper value.

摘要： A vehicle (10) is disclosed which includes a thermostat (22) in a bottom hose (24) of a radiator (16). An onboard diagnostic arrangement is provided to monitor the efficiency of the thermostat (22). Temperature sensors (S1, S2) are provided to monitor the temperature of the coolant across the radiator (16) so that a controller (40) can derive from those measurements the temperature differential across the thermostat (22). If the temperature Teng of the coolant at the thermostat inlet is below the thermostat opening temperature Topen and the differential temperature between the thermostat inlet temperature Teng and the thermostat outlet temperature Trad is below a fault threshold Dtstat, the thermostat (22) is evaluated as being stuck open or leaking, which results in a fault being recorded and a malfunction indicator lamp (MIL) being illuminated.
