What is the approximate fuel consumption of a 1.5t engine idling with AC on for one hour?
2 Answers
1.5t idling with AC on for one hour consumes approximately 1L of fuel. Here are some fuel-saving methods: 1. Maintain good vehicle condition: Ensure the vehicle is tuned to optimal performance and change engine oil promptly. Also, maintain proper tire pressure. A well-maintained car requires less effort and improves fuel efficiency. 2. Close windows on highways: Open windows increase drag resistance, which can add an extra 10% to fuel consumption. 3. Shift gears properly: Driving at high speeds in low gear can increase fuel consumption by 45% compared to using the correct gear. 4. Reduce excess weight: Unnecessary items in the car all contribute to increased fuel consumption.
I often enjoy studying car mechanics. A 1.5T engine idling with the AC on for about an hour typically consumes between 1.0 to 1.3 liters of fuel, depending on the engine design and AC usage intensity. When the AC is on, the compressor consumes power, adding extra load and increasing fuel consumption by 20%-30% compared to pure idling. In summer, high temperatures lead to even higher fuel consumption, possibly up to 1.5 liters, due to the fan running at high speeds. In winter, the AC heating consumes slightly less. Prolonged idling like this can lead to carbon buildup, causing engine vibrations and wear. It's advisable to avoid long periods of idling while parked and use apps to monitor real-time data. To save fuel, consider models with start-stop systems or regularly maintain the AC filter. Overall, estimating around 1.2 liters as a reference, this translates to roughly 10 yuan in fuel costs, but small amounts add up to significant waste over time.
