AC Engine pressure drops immediately after starting

A car’s AC is directly connected to the engine. The compressor of AC is powered by engine power. That’s why when we turn on the AC, the engine is forced to work even harder. The engine burns more fuel for this extra work. This is the reason why running AC consumes more fuel. This is more evident in urban traffic.

How much fuel is consumed in normal conditions?

According to automobile industry figures, a car’s AC burns about 0.2 to 0.4 liters more fuel every hour under normal driving conditions and normal driving conditions. It also depends on the vehicle engine, environment and AC settings. If it’s hot outside, the AC has to work harder to keep the cabin cool; And also burns more fuel.

What is the difference between small and big cars??

Vehicle size has a big impact on fuel costs. A small car’s cabin size is small, so the AC doesn’t have to work as hard to cool it down. 0.2 liters of fuel per hour was sufficient for such a small car. On the other hand, in larger cars like SUVs due to their larger size and larger compressors, the AC’s work may increase and fuel consumption may be as high as 0.8 liters.

Direct effect on mileage

If you use regular AC, it also affects the mileage of the car a lot. According to experts, if the AC is on continuously during long journeys, it can increase the overall fuel consumption by 8 to 10 percent.

In a standing car AC Driving is a sacrifice in cost

A lot of people are running the AC while waiting in the parking lot with the engine running. This habit is not at all good for saving fuel. In a stationary car, the engine is constantly burning fuel, but the vehicle is not moving. In that case, fuel is spent every minute without mileage.
