For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. [1] For many single-cylinder motorcycle engines, idle speed is set between 900 and 1100 rpm. Two-cylinder motorcycle engines are often set around 1000 rpm. [2]
Idle creep, sometimes called idle speed or just creep [citation needed] is the default speed that a vehicle with an automatic transmission will move either forward or in reverse when the change lever is in D for drive or R for reverse and the foot is taken off the brake pedal but the accelerator pedal is not depressed. This behaviour is due to ...
Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be mutually exclusive; an engine may be de-tuned with respect to output power in exchange for better economy or longer engine ...
Letting a car idle requires more time for the vehicle to warm up and allows excess fuel to get into the engine, which isn't good for wear and tear.
An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed . [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.
In other respects, it was a typical "feedback" carburetor system of the early-1980s, using a stepper motor to control fuel mixture and a two-stage "Sole-Vac" (which used a solenoid for one stage, and a vacuum motor for the other) to control idle speed. [6]
You may idle while waiting in a drive-through line, picking up a curbside order or dropping off the kids at school or when you're stuck in standstill traffic. Though idling is common, it's not ...
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
