The temperature of the air entering the vehicle's interior can be controlled by using a valve limiting the amount of coolant that goes through the heater core. Another method is blocking off the heater core with a door, directing part (or all) of the incoming air around the heater core completely, so it does not get heated (or re-heated if the ...
a thermostat to control temperature by varying the amount of coolant going to the radiator; a fan to draw cool air through the radiator. The combustion process produces a large amount of heat. If heat were allowed to increase unchecked, detonation would occur, and components outside the engine would fail due to excessive temperature. To combat ...
However, once water boils, it is an insulator, leading to a sudden loss of cooling where steam bubbles form. Steam may return to water as it mixes with other coolant, so an engine temperature gauge can indicate an acceptable temperature even though local temperatures are high enough that damage is being done. An engine needs different temperatures.
A temperature switch or a thermistor can control the evaporator coil surface temperature, and a pressure switch or sensing element can monitor the suction pressure (which is in relationship with the refrigerant's evaporating temperature). Both control means can act (either directly or by means of a control unit fed by their data) upon the ...
The temperature range lies between the minimum and maximum operating temperature of the element. Elements can cover temperatures ranging from -15 °C to +120 °C. Elements may move in proportion to the temperature change over some part of the range, or may open suddenly around a particular temperature depending on the composition of the waxes.
The temperature of the PACK outlet air is controlled by the adjusting flow through the ram-air system (below), and modulating a temperature control valve (TCV) which bypasses a portion of the hot bleed air around the ACM and mixes it with the cold air downstream of the ACM turbine.
Device to measure the temperature to which the coolant protects the car from freezing. Water is the most common coolant. Its high heat capacity and low cost make it a suitable heat-transfer medium. It is usually used with additives, like corrosion inhibitors and antifreeze.
This prevented driveability problems due to unnecessary exhaust induction; NO x forms under elevated temperature conditions generally not present with a cold engine. Moreover, the EGR valve was controlled, in part, by vacuum drawn from the carburetor's venturi, which allowed more precise constraint of EGR flow to only those engine load ...
