Parasitic load or parasitic loss may refer to in internal combustion engines, it refers to devices that take energy from the engine in order to enhance the engine's ability to create more energy or convert energy to motion. in electricity production, it is any of the loads or devices powered by the generator, not contributing to net electric yield
Power gating affects design architecture more than clock gating.It increases time delays, as power gated modes have to be safely entered and exited. Architectural trade-offs exist between designing for the amount of leakage power saving in low power modes and the energy dissipation to enter and exit the low power modes.
In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit, or a subpart of it, is not in use or ignores clock signal.
Standby power, also called vampire power [1], vampire draw, phantom load, ghost load, or leaking electricity, refers to how electronic and electrical appliances consume electric power. At the same time, they are switched off (but are designed to draw some power) or in standby mode. It only occurs because some devices claim to be "switched off ...
E.g. in a truck with a Caterpillar C15 engine, it is achieved by going all the way up to 1950RPM, then shifting to a gear that will put the engine at 1500RPM. In contrast, using progressive shifting, i.e. maintaining maximum torque , the overall acceleration is slower but there is increased fuel efficiency and lower wear of the engine due to ...
The Environmental Protection Agency on Friday set strict emissions standards for heavy-duty trucks, buses and other large vehicles, an action that officials said will help clean up some of the ...
The other unit is a hot-standby or a hot spare unit, ready to take over if the master unit fails. When the master unit fails, an automatic failover to the hot spare occurs within a very short time and the outputs from the hot spare, now the master unit, are delivered to the controlled devices and displays.
Many newer semi-trucks have small auxiliary power units (APUs) to run accessories more efficiently while the truck is parked. Hybrid vehicles typically shut down their internal combustion engines while stopped, although some conventional vehicles are also including start-stop systems to shut off the engine when it would otherwise idle.
