Idle is a state that a computer processor is in 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.
The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
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.
In a multiprocessor system, there is one idle thread associated with each CPU core. For a system with hyperthreading enabled, there is an idle thread for each logical processor. The primary purpose of the idle process and its threads is to eliminate what would otherwise be a special case in the scheduler. Without the idle threads, there could ...
Kenworth will offer a new factory-installed and integrated engine-off heating and cooling idle management system for its long-haul T680 with a 76-inch sleeper.
ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...
EDC injection inline pump. The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption.
Generic powertrain – The generic powertrain pertains to a vehicle's emission system and is the only regulated controller name. Other controllers – All other controller names are decided upon by the individual OEM. The engine controller may have several different names, such as "DME", "Enhanced Powertrain", "PGM-FI" and many others.
