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]
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.
The engine will not stop if the car is moving, even if the aforementioned steps are followed (this is not true for all cars). The engine restarts when the clutch is pressed prior to selecting a gear to move the car. The engine may also restart if there is a demand for power from, for example, the air conditioning system.
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 ...

[16] [17] In 2010, Mitsubishi developed and started mass production of its 4N13 1.8 L DOHC I4, the world's first passenger car diesel engine that features a variable valve timing ...
The Toyota Y engine is a series of overhead valve straight-four petrol engines manufactured by Toyota from 1982 through 1996. The Y engine has mostly been used in commercial and off-road vehicles. The valve arrangement from the Toyota K engine is interchangeable with this engine. Translated from Japanese Wiki ja:トヨタ・Y型エンジン
