A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
Sustainable automotive air conditioning is the subject of a debate – also known as the Cool War – about the next-generation refrigerant in car air conditioning. An advocacy group, The Alliance for CO 2 Solutions , supports the uptake of carbon dioxide (CO 2 ) as a refrigerant in passenger cars, and the chemical industry is developing new ...
The transmission control unit (TCU) in older automobiles with a clutchless manual transmission (without a clutch pedal) typically consists of an electrical switch connected to the gearshift, that is activated whenever the internal transmission control unit senses driver touching the gearshift to switch gears, which then primes a sensor or ...
In 2012, wind tunnel tests were completed on an earlier version of the fan and in 2015, 275h of testing were completed on a fan rig. More than 175h of ground testing of key components were completed in October 2017, on a shorter duct inlet, a part of the nacelle and a fan with lower-pressure ratio blades, significantly fewer than the 20 blades ...
The AW70 series is a group of 4-speed automatic transmissions built by Aisin-Warner, a Japanese-American joint venture company, for the Volvo 240, 740 and 940. There are three different models within the series, all based on the AW70, which was first used in 1981 Volvo models.
The 22-blade fan of an A320's V2500-A1 Rolls-Royce based the ten-stage high-pressure compressor on an eight-stage run in the RB401 in the mid 1970's followed by a nine-stage run in the RJ.500 . The V.2500 would use ten stages, with the first four with variable stators, giving a pressure ratio of 20:1. [ 4 ]
In a typical auto/light truck installation, there is an individual switch at each window and a set of switches in the driver's door or a-frame pillar, so the driver can operate all the windows. These switches took on many different appearances, from heavy chrome plate to inexpensive plastic.
