摘要:
A method of conserving energy during a heating event wherein a coolant is heated in a cooling system is disclosed. The method includes establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature lower than the first set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point.

In order to appropriately control the temperature state of multiple equipment having differing management temperatures, while preventing complication of the apparatus structure, a cooling apparatus for a hybrid vehicle is provided with a seventh flow path 30g which flows coolant which has flowed only through a main flow path 22a of a radiator 22 to a water jacket 25 via a first thermostat 23 which has an induction temperature set relatively high; an eighth flow path 30h which flows coolant which has flowed through the main flow path 22a and a sub flow path 22b of the radiator 22 to the water jacket 25 via a second thermostat 24 which has an induction temperature set relatively low, and also supplies the coolant to a PDU 14 and a downverter 15; and a bypass flow path 30j which connects a fifth flow path 30e which supplies coolant discharged from the water jacket 25 to the radiator 22, and a position of the eighth flow path 30h on a downstream side of the second thermostat 24.

摘要:
A cooling system for an engine wherein a cylinder block side is mounted with a stagnation chamber for stagnating a temperature sensing unit of a sub-thermostat portion of cooling water discharged to a high temperature passage via an outlet of a cooling water passage of the cylinder block side, enabling opening and closing of the sub-thermostat only via the temperature of the cooling water at the cylinder block side. The cooling system includes a main thermostat and a sub-thermostat for individually controlling the flow of cooling water in a cylinder block and a cylinder head. The stagnation chamber, where a cooling water discharged from the cylinder block is stagnated, is installed inside a sub-thermostat housing where a sub-thermostat is mounted. The stagnation chamber is positioned therein with a temperature sensing unit. The stagnation chamber communicates with a cooling water discharge passage of the cylinder head via a confluence passage.
摘要:
A method for determining the use of a block heater in an internal combustion engine and compensating for the effects that such heaters can have on an engine coolant sensor. The method uses measurements of ambient air temperature to determine if the use of a heater is likely and then compares the measured coolant temperature with an inferred coolant temperature to verify the usage of the block heater when the difference is significant. When use of a heater is detected, the value for coolant temperature initially supplied to the engine control system is compensated with a normalized coolant temperature value that is based on a functional relationship between the inferred engine temperature and the measured coolant temperature. Then as the mechanism of the engine begins to mechanically turn and the coolant is circulated, the normalized value of coolant temperature is filtered in a way that the normalized value approaches the temperature reading from the coolant sensor, as the starting process continues.
