The DOT code [1] is an alphanumeric character sequence molded into the sidewall of the tire and allows the identification of the tire and its age. The code is mandated by the U.S. Department of Transportation [2] but is used worldwide. [3] The DOT code is also useful in identifying tires subject to product recall [4] or at end of life due to age.
UN Regulation 37 covers motor vehicle filament lamps. These are categorized in three groups: those without general restriction that can be used in any application, those acceptable only for signalling lights (not for road illumination lamps), and those no longer allowable as light sources for new type approvals but still permitted for production as replacement parts.
6061 sheet in the T4 condition can be formed with limited ductility in the cold state. For deep draw and complex shapes, and for the avoidance of spring-back, an aluminium hot stamping process ( Hot Form Quench ) can be used, which forms a blank at a elevated temperature (~ 550 C) in a cooled die, leaving a part in W-temper condition before ...
In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
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. This fluid is designed to meet the unique demands of an automatic transmission.
Cut-away view turbocharger (turbine section on the left, compressor section on the right) 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 ...
The Carnot engine is the most efficient heat engine which is theoretically possible. [ 3] The efficiency depends only upon the absolute temperatures of the hot and cold heat reservoirs between which it operates. A heat engine acts by transferring energy from a warm region to a cool region of space and, in the process, converting some of that ...
Thermodynamics. The dual combustion cycle (also known as the mixed cycle, Trinkler cycle, Seiliger cycle or Sabathe cycle) is a thermal cycle that is a combination of the Otto cycle and the Diesel cycle, first introduced by Russian-German engineer Gustav Trinkler, who never claimed to have developed the cycle himself.
