Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be an interference fit to the crankshaft in order to operate in an effective ...
P0 - beside, inside or in front of engine (Ex: Belt-Alternator-Starter or Integrated Starter-Generator ) P1 - engine output shaft (Ex: Integrated motor-generator (IMG), integrated motor assist , flywheel assist system (FAS) [76]) P2 - between engine and transmission; P2.5 - inside transmission; P3 - transmission output shaft; P4 - rear axle
Serpentine belt (foreground) and dual vee belt (background) on a bus engine Belt tensioner providing pressure against the back of a serpentine belt in an automobile engine. A serpentine belt (or drive belt [1]) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air ...
An Alexanderson alternator is a rotating machine, developed by Ernst Alexanderson beginning in 1904, for the generation of high-frequency alternating current for use as a radio transmitter. It was one of the first devices capable of generating the continuous radio waves needed for transmission of amplitude modulated (AM) signals by radio.
Ideally, by the time the capacitor runs out of charge, the switching event has finished, so that the load can draw full current at normal voltage from the power supply and the capacitor can recharge. The best way to reduce switching noise is to design a PCB as a giant capacitor by sandwiching the power and ground planes across a dielectric ...
A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain. The earliest evidence of pulleys dates back to Ancient Egypt in the Twelfth Dynasty (1991–1802 BC) [1] and Mesopotamia in the early 2nd millennium BC. [2]
A processor board with decoupling of the power rails at every other chip using small capacitors. The through-hole technology shown is obsolescent (surface-mount technology is now the norm) but the general principles of decoupling remain the same.
A non-ideal DC voltage waveform can be viewed as a composite of a constant DC component (offset) with an alternating (AC) voltage—the ripple voltage—overlaid. The ripple component is often small in magnitude relative to the DC component, but in absolute terms, ripple (as in the case of HVDC transmission systems) may be thousands of volts.
