The engine rotational speed maintained without driver throttle input, ensuring stable operation under minimal load. See: Engine Operating Conditions

The angular position at which spark occurs before top dead centre to optimise combustion timing. See: Ignition Timing Control

: The system responsible for initiating combustion in spark-ignition engines through controlled electrical discharge. See: Spark Ignition Systems

A rotating component that transfers energy to a fluid, used in pumps and torque converters. See: Fluid Energy Transfer Devices

A theoretical pressure representing engine cylinder performance independent of displacement. See: Engine Performance Metrics

The components responsible for supplying air to the engine, including filters, ducts, and manifolds. See: Air Intake Systems

The resistance of a mass to changes in velocity, influencing acceleration and braking behaviour. See: Vehicle Dynamics Fundamentals

A precision device delivering controlled quantities of fuel into the intake air or combustion chamber. See: Fuel Injection Systems
