Automatic transmission fluid. For the transmission lubricant, see gear oil. Automatic transmission fluid (ATF) is a hydraulic fluid that is essential for the proper functioning of vehicles equipped with automatic transmissions. Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle.
A heater core is a radiator -like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface area for heat transfer to air that is forced past them by a fan, thereby ...
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. [ 1][ 2] The current categorisation ...
The engine temperature on modern cars is primarily controlled by a wax-pellet type of thermostat, a valve that opens once the engine has reached its optimum operating temperature. When the engine is cold, the thermostat is closed except for a small bypass flow so that the thermostat experiences changes to the coolant temperature as the engine ...
This was the first GM ATF to require red dye as an aid in fluid leak detection. Prior to this fluid, GM ATF was the same color as engine oil. Aftermarket ATF was available with red dye. GM DEXRON (B)-licensed products have a license number on the container that begins with the letter B. Example: B10001. This fluid is backward compatible with ...
The Ford Model T used a 177 cu in (2.9 L) sidevalve, reverse-flow cylinder head inline 4-cylinder engine. It was primarily a gasoline engine. It produced 20 hp (14.9 kW) for a top speed of 45 mph (72 km/h). It was built in-unit with the Model T's novel transmission (a planetary design ), sharing the same lubricating oil .
The VVT system is a 2-stage hydraulically controlled cam phasing system. VVT-i varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust ...
In the extraction of petroleum (and other heavy-duty fluid handling contexts), a choke valve (or "choke") is an adjustable flow limiter that is designed to operate at a large pressure drop, at a large flow rate, for a long time. A choke is often a part of the "Christmas tree" at the wellhead . The most familiar choke design is a solid cylinder ...
