摘要： In order to prevent wasteful cooling fan energization when the radiator or condensor of an evaporative type cooling system is partially filled in a manner which hinders heat exchange promotion and defeats any merit derived by operating a fan at full power, the fan is operated at a lower level to reduce fan noise and power consumption.

摘要： An evaporative cooling system features a reservoir which contains only sufficient coolant to fill the radiator when the engine is not in use and thus reduces the weight of the system. The remaining sections of the cooling circuit such as the upper section of the coolant jacket which are fairly resistant to corrosion are filled with air during non-use periods. The air is suitably purged out during engine warm-up and operation in accordance with the temperature differential which exists between the coolant jacket and the bottom of the radiator.

摘要： In order to obviate vapor locking and subsequent cavitation of a pump which returns coolant vapor condensate from a radiator to the coolant jacket of an evaporative type cooled internal combustion engine and maintains the highly heated structure of the engine immersed in a predetermined depth of liquid coolant, the load on the pump is sensed by determining the amount of electrical current the pump is drawing and in the event that the load is at a level indicative of pump cavitation the connection between the radiator and the pump is interrupted and communication between a reservoir and the pump is established so as to introduce cool liquid coolant into the induction port of the pump.

摘要： An engine anti-knock control arrangement controls both the ignition timing system and an evaporative cooling system so that when the engine is operating in a predetermined engine speed and load zone and engine knock is detected, the cooling system is operated to reset the temperature to which the coolant (and therefore the engine) should be controlled, to a predetermined minimum value and the ignition timing incrementally retarded until the knocking phenomenon terminates. While the temperature is dropping and knocking is absent, the ignition timing is incrementally advanced until the knock threshold is reached and thus brings the timing as close as practical to the MBT value for the instant set of operating conditions. Cyclic repetition of the ignition timing advancement and retardation holds the timing at MBT while the engine is operating in the predetermined zone.

摘要： In order to rapidly bring the temperature of the coolant in the coolant jacket of an evaporative type cooling system to a derived target value, both the rate of heat exchange between the condenser or radiator of the system and the surrounding ambient atmospheric air and the amount of coolant in the cooling circuit are varied in a manner to change the pressure and therefore the boiling point of the coolant. With the invention coolant is positively pumped to and from a reservoir which is maintained at atmospheric pressure into and out of a cooling circuit which is hermetically sealed during engine operation.

摘要： A vapor cooled type internal combustion engine is provided with an auxiliary reservoir and a coolant management system. The management system establishes fluid communication between the reservoir and a cooling circuit of the engine in a manner to fill the latter with liquid coolant when the engine is not in use and thus exclude contaminating non-condensible air from same, and monitors the operation of the system when operating in a closed mode to determine if too much or too little coolant has been retained in the circuit following a warm-up mode wherein the excess coolant which fills the system when cold, is displaced by its own vapor pressure. The management system also ensures that the cooling circuit is not switched from closed to open states while the possibility of superatmospheric pressures developing therein exist and thus prevents violent displacement of coolant out of the circuit to the reservoir in a manner which invites spillage of coolant and the entry of large amounts of contaminating air.

摘要： A spark timing control system for reducing engine noise in an internal combustion engine utilizing a sensor for detector for detecting engine vibration, a filtering device receiving the output of the sensor and passing frequency components within a range of 500 to 2000 Hz, and a generating circuit responsive to the passed frequency components for generating an output signal when the level of the passed frequency outputs exceeds a reference value. Spark timing is retarded when the output signal is received from the generating circuit thereby reducing engine noise.
