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]
A start-stop system off button on a Perodua Myvi. A vehicle start-stop system or stop-start system (also known as S&S, micro hybrid, or micro hybrid electric vehicle (μHEV)) [1] automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.
Some idle management technologies are so comprehensive, they are able to manage the engine's on/off ignition while retaining control of auxiliary functions, such as vehicle climate, anti-theft, operator security, and more, even when the engine is powered off. Idle reduction can also be achieved by more efficient control of stop lights [34] and ...
If you drive a car regularly, the odds are high that you'll have to sit and wait in it with the engine running at some point. The practice is known as idling, and it's common to do it during ...
Starting the engine in cold start temporarily takes more fuel until operation temperature of the engine is detected by the ECU. Gliding vehicles equipped with torque converter-based automatic transmissions causes damage due lack of lubrication. Also, restarting the engine by clutch from the vehicle's kinetic energy or drag is not possible.
The result is an engine that fails to maintain idle RPM and frequently stalls. A jammed actuator may be freed simply by cleaning it. However an actuator that has stopped working due to a fault in its servomotor will need replacement. Air leaks in either the stepper housing or pipes will cause elevated idle RPM.
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 ...
Especially turbodiesel engine should let idle for awhile before driving; one reason is that, turbo does not get oil right after the start. Other problems are related to thermal expansion. 80.221.251.172 21:21, 4 June 2012 (UTC) All engines can idle. Not just cars. A generator can idle. A weedeater can idle.
