Idle speed, sometimes simply called " idle ", is the rotational speed an engine runs at when the engine is idling, that is when the engine is uncoupled from the drivetrain and the throttle pedal is not depressed. In combustion engines, idle speed is generally measured in revolutions per minute (rpm) of the crankshaft.
Idleness is a lack of motion or energy. In describing a person, idle suggests having no labor: "idly passing the day". In physics, an idle machine exerts no transfer of energy. When a vehicle is not in motion, an idling engine does no useful thermodynamic work. In computing, an idle processor or network circuit is not being used by any program ...
All idling is bad — and it's worse the longer you idle for — but idling in traffic or poorly ventilated spaces like parking garages or under overpasses "can be particularly harmful," Ganjian says.
IDLE (short for Integrated Development and Learning Environment) is an integrated development environment for Python, which has been bundled with the default ...
Idle (CPU) A computer processor is described as idle when it is not being used by any program . Every program or task that runs on a computer system occupies a certain amount of processing time on the CPU. If the CPU has completed all tasks it is idle. Modern processors use idle time to save power. Common methods are reducing the clock speed ...
Idle reduction is a rapidly growing trend in US federal, state, local and fleet policy. [citation needed] Idling contributes significantly to the transportation sector's portion of yearly greenhouse gas emissions. The US Department of Energy is putting forth a huge effort through the Energy Efficiency and Renewable Energy Program to increase ...
An idler gear is a gear wheel that is inserted between two or more other gear wheels. The purpose of an idler gear can be two-fold. Firstly, the idler gear will change the direction of rotation of the output shaft. Secondly, an idler gear can assist to reduce the size of the input/output gears whilst maintaining the spacing of the shafts.
Cross-sectional schematic. A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4] The primary method of adding fuel to the intake air is through the Venturi tube in the main metering circuit, though various other ...
