Is It Harmful to Keep the Car Running While Stationary?

[OQuinn]

Keeping the car running without moving has minimal impact on the vehicle, but it does consume fuel. Below is relevant information about ignition: Traditional Ignition: The mechanical ignition system operates by the crankshaft driving the distributor shaft to rotate. The cam on the distributor shaft turns, causing the primary contacts of the ignition coil to open and close, generating high voltage. This high-voltage ignition is then distributed by the rotor on the distributor shaft to the spark plugs of each cylinder in the required sequence, where the spark plugs generate sparks to ignite the gas in the combustion chamber. Electronic Ignition: The electronic ignition system is entirely different from the mechanical system, featuring an electronic control device for ignition. Inside this device is a map (MAP) of ignition control curves required for various engine operating conditions. A series of sensors, such as engine speed sensors, intake manifold vacuum sensors (engine load sensors), throttle position sensors, and crankshaft position sensors, determine the engine's operating state.
