What is the fuel consumption of the FAW J6P idling with air conditioning on?
3 Answers
The fuel consumption of the FAW J6P idling with air conditioning on is 2 liters per hour, but it is not recommended to idle with the air conditioning on as it can cause significant carbon buildup. The FAW J6 is a heavy-duty truck, and most heavy-duty trucks are most fuel-efficient when traveling at 70 km/h under standard load. More details about the FAW J6P are as follows: 1. Vehicle Data: The FAW J6 is a 6x4 tractor with a body length of 7300 mm, width of 2550 mm, height of 3980 mm, wheelbase of 3450 mm + 1350 mm, front track of 2020 mm, rear track of 1850 mm, curb weight of 9.6 tons, maximum towing capacity of 39.205 tons, and a top speed of 129 km/h. 2. Engine: The FAW J6 uses a Xichai inline six-cylinder diesel engine with a displacement of 11.05L, paired with a FAW Jiefang 12-speed manual transmission. It has a maximum output power of 342 kW, maximum torque of 2200 Nm, maximum horsepower of 460, maximum torque speed range of 1000-1400 rpm, and rated speed of 1900 rpm. 3. Other Configurations: The vehicle seats 2 people, features an aluminum alloy fuel tank with a capacity of 800L, has 10 tires with size 12R22.5, a rear axle of 435 welded bridge, permissible load of 18000 kg (two-axle group), rear axle ratio of 3.727, and spring leaf count of 3/4.
The fuel consumption of the FAW J6P when idling with the air conditioning on is indeed noteworthy. I remember driving similar trucks before, and the consumption typically ranged from 2-4 liters per hour, depending on the engine model and AC settings. From my experience, if the temperature is high and the AC is set to maximum, the fuel consumption can easily exceed 3 liters. On the other hand, if the idling time is short, it can be kept around 2 liters. In fact, prolonged idling not only wastes fuel but also wears out the engine, so I recommend avoiding it whenever possible—either by turning off the engine when parked or installing an auxiliary battery system to power the AC. During regular driving, I also make it a habit to check the coolant temperature and tire pressure, as these small details can contribute to overall fuel savings and reduce operating costs.
For heavy-duty trucks like the FAW J6P, the fuel consumption when idling with the air conditioning on typically ranges from 2 to 4 liters per hour, which is influenced by engine load and external temperature. As a car enthusiast, I’ve observed through practical experience that fuel consumption tends to be higher when the truck’s engine runs steadily and the air conditioning operates at high power. A simple test is to check the fuel gauge before parking—if the temperature exceeds 30°C, running the AC can double the fuel consumption. From a vehicle design perspective, the AC compressor increases the engine’s workload, leading to higher fuel consumption. A practical approach is to use the AC only when necessary, such as during short breaks under intense sunlight. Opting for an efficient AC compressor can also help reduce the load. Understanding these factors can aid in planning travel schedules more economically.
