What is the idle fuel consumption of a car?

[VonAdriel]

Introduction to car idle fuel consumption: For current general vehicles with a displacement of 1.5-1.8 liters, the hourly idle fuel consumption is approximately 1-2 liters. Additionally, if the air conditioning is turned on during summer, the idle fuel consumption will be even higher. The higher the car's displacement, the more fuel it consumes per hour at idle. Below is relevant information about car idle fuel consumption: 1. Idle fuel consumption varies by vehicle model and is also related to displacement. If idling with the air conditioning on, some cars will automatically assess the load and adjust the idle speed and fuel supply accordingly, which is also influenced by factors such as coolant temperature, air intake, and ambient temperature. 2. It is recommended that car owners turn off the engine rather than let it idle for extended periods while waiting. Prolonged idling not only increases fuel consumption but also leads to incomplete fuel combustion, resulting in carbon deposits.
