SUMMARY

Idling of an engine refers to the operation of the engine at a slow speed while it is not under load. This condition is characterized by the engine running without any significant power demand, distinguishing it from revving the engine. In vehicles equipped with automatic gearboxes, the car may still move forward slowly during idling. The idle speed is defined as the minimum speed at which the engine can operate without stalling or exhibiting violent rocking.

PREREQUISITES
  • Understanding of engine mechanics
  • Familiarity with automatic transmission systems
  • Knowledge of engine speed measurement
  • Basic automotive terminology
NEXT STEPS
  • Research the concept of engine idle speed control
  • Learn about the effects of idling on fuel efficiency
  • Explore automatic transmission behavior during idling
  • Investigate the causes of engine stalling at low speeds
USEFUL FOR

Automotive enthusiasts, mechanics, and anyone interested in understanding engine operation and efficiency during idling conditions.

Idling means running an engine at slow speed when it is not on load.

Most situations require both conditions (slow and no load) so revving the engine whilst not on load is not idling.

However cars with automatic gearboxes will drive foward slowly when the engine is 'idling'

Another way to look at it is to say that idle speed is the slowest speed the engine will run at without stalling or rocking violently.
