How Much Does Using Air Conditioning in Summer Increase Car Fuel Consumption?

[DeBlakely]

For most household cars, the engine displacement generally ranges between 1.3-2.5L, with fuel consumption typically between 6-10L/100km. When the air conditioning is turned on, fuel consumption usually increases by 10-15% of the original consumption, resulting in an additional 0.6-1.5L per 100 kilometers. Below is relevant information about fuel consumption: 1. Fuel consumption per 100 kilometers: This refers to the amount of fuel consumed by a vehicle traveling 100 kilometers at a certain speed on the road. It is a theoretical indicator for vehicles. Manufacturers measure this value in an objective environment using a dynamometer installed on the vehicle's chassis, converting it into speed parameters, and then calculating the theoretical experimental fuel consumption data for the vehicle model at specified speeds. 2. Road condition fuel consumption: This is a fuel indicator calculated based on repeated tests where the vehicle travels on specified roads at regulated speeds and times. Also known as multi-condition road cycle fuel consumption, the standard specifies that each cycle includes various driving conditions and records parameters such as gear shift timing, parking duration, driving speed, acceleration, braking, and deceleration. This method yields values that are closer to actual conditions.
