tühikäigupöörete

Tühikäigupöörete refers to the rotational speed of an engine when it is operating without any load applied. This is the lowest stable speed at which an internal combustion engine can run. In simpler terms, it's the engine's idle speed. The term originates from Estonian, where "tühikäik" means idle or no load, and "pöörete" signifies revolutions or rotations.

The tühikäigupöörete is crucial for several reasons. Firstly, it ensures the engine remains running smoothly without stalling when the vehicle is stationary or when the clutch is disengaged. Secondly, it allows essential engine components, such as the oil pump and alternator, to function and circulate fluids and generate electricity. The specific tühikäigupöörete is determined by the engine's design and is typically maintained by the engine control unit (ECU) or a dedicated idle control system.

Factors like engine temperature, air conditioning load, and power steering can influence the tühikäigupöörete. Modern engines often have systems that automatically adjust the idle speed to compensate for these varying loads, ensuring consistent performance and preventing stalling. Maintaining the correct tühikäigupöörete is important for fuel efficiency and engine longevity. Consistently high or low idle speeds can indicate underlying engine issues that require attention.
