摘要： The invention relates to a method for monitoring a coolant circuit (16) of an internal combustion engine (10) comprising at least one heat exchanger (18, 22), a control valve (26), a coolant pump (32) and an electronic control unit (76). The invention is characterized in that the control unit (76) predetermines a permissible upper and lower deviation of a reference parameter from a set value from operating parameters of the internal combustion engine (10), using deviation characteristic diagrams (56, 58) and compares said deviations with a differential between a set value and an actual value of the reference parameter, whereby said actual value is determined from parameters of the volumetric flow of the coolant, optionally with the help of characteristic diagrams (42, 46, 74).

摘要： A method of diagnosing a cooling system of a vehicle engine, including the steps of: acquiring operating data relative to operation of the cooling system (cooling system radiator water temperature/fan rotation speed) during a trip time (Ttrip) between turn-on of the engine and subsequent turn-off of the engine; processing the acquired data, and accumulating the data for each trip to create a database; and examining the location of the data within the database to determine malfunction and/or potential malfunction situations of the cooling system.

摘要： An OBD system is provided for monitoring an ozone depletion system that includes a catalyst coating containing MnO2 applied to a heat exchange surface on a moving vehicle over which atmospheric air passes. A physical characteristic of the catalyst coating or a material containing a physical characteristic within the catalyst coating is sensed to determine the presence or absence of the catalyst coating for detecting catastrophic failure of the ozone depleting system and/or degradation or wear of the catalyst coating to ascertain the efficiency of the catalyst coating.

摘要： According to the invention, a method for the recognition of cooling system faults, in a motor vehicle engine, is disclosed, whereby, with the aid of an algorithm, not just a fault in the cooling system can be recognised, but also whether the thermostatic valve, or the temperature sensor are faulty. The different fault recognition is achieved, whereby a second model temperature curve is calculated, for the case when the thermostat remains open. A first model temperature curve is calculated, for the case when the cooling system is functioning normally. By comparing the curve shape for the measured, actual value with both model temperature curves, a selective diagnosis may be carried out, permitting the determination of whether the temperature sensor or the thermostatic valve are defective. No additional hardware is required.

摘要： A malfunction detecting apparatus of a radiator fan system includes a steady-state discrimination unit (100 - 108) which detects whether an operating condition of an internal combustion engine (10) is in a steady state. A temperature change measuring unit (206, 220 - 226) measures a change in a temperature of cooling water of the engine when the operating condition of the engine is detected to be in the steady state and a control signal to start rotation of a cooling fan (18) of the radiator fan system is output. A malfunction detecting unit (232 - 238) detects that a malfunction in the radiator fan system has occurred, when the temperature change measured by the temperature change measuring unit is smaller than a reference value.

摘要： A dual function sensor particularly useful with vehicular coolant systems indicates when a coolant liquid becomes corrosive to such cooling system materials as well as when the liquid falls to a low level condition. A reference (26) and a sense electrode (28) are used to probe the condition of the coolant liquid. Integral electronics provide signal conditioning and transmitting to indicate both corrosive and low level coolant conditions. The sensor assembly (10) mounts directly onto a tubular coupling (24) on the vehicle radiator by pushing the assembly onto the coupling (24) until a spring wire element (40) snaps past a lip (24.2) formed on the free distal end of the coupling (24). An electrical connector shroud (34) extends from the assembly (10) and accommodates a mating male connector which is pushed onto the shroud (34) until a clip mounted on the male connector snaps over a locking tab (34.1) located on the shroud (34). The male connector typically is connected to an engine control module (ECM).
