idle rpm
1Idle speed — is the minimum operating speed (generally measured in revolutions per minute, or rpm, of the crankshaft) of a combustion engine. At idle speed, the engine generates enough power to run reasonably smoothly and operate its ancillaries (water pump,… …
2idle speed — The lowest speed at which an engine operates smoothly when it is not carrying any type of load. In the case of aircraft engines, it is the engine RPM when the throttle or power control lever is fully closed. In cold weather conditions, it may be… …
3idle speed stabilizer — A device which ensures steady engine rpm at idle speed. An electronically controlled air bypass around the throttle. Also called idle speed actuator or a constant idle system …
4off-idle mixture — The fuel air mixture ratio given by a fuel metering system during the period when the engine is transitioning from its idle RPM to a speed at which fuel is metered by the main metering system …
5curb idle — Normal idle rpm. Computer controlled on many modern vehicle …
6ground idle — The governed RPM on the ground with throttles set to the minimum or fully back position. Normal ground idling is in the range of 60 to 70% of the maximum RPM. In the case of twin spool engines, it is the N1 RPM (RPM of the low pressure… …
7flight idle — An engine RPM in flight at a given altitude with the throttle set to the minimum, or idle, position. The flight idling RPM typically increase with an increase in altitude …
8idling RPM — The engine RPM with the throttle set to the minimum or idle position on the ground. Idling RPM varies with altitude; the higher the height, the higher will be the idling RPM …
9Massive array of idle disks — In computing, a massive array of idle disks (more commonly known as a MAID) is a system using hundreds to thousands of hard drives for nearline storage of data. MAID is designed for Write Once, Read Occasionally (WORO) applications. In a MAID… …
10reverse idle — A power lever position where the thrust reversers are deployed but the engine RPM remains idle …
