Parking air conditioning requires a battery of 24V150A to 300A. Below is an introduction to parking air conditioning: Introduction to parking air conditioning: It refers to an onboard air conditioning system used during parking, waiting, or resting. Parking air conditioning is an in-vehicle air regulator that utilizes the DC power from the vehicle's battery to allow continuous operation of the air conditioning while parked or resting. It adjusts and controls parameters such as temperature, humidity, and air velocity inside the vehicle to meet the comfort and cooling needs of truck drivers. Reasons why parking air conditioning is cooling-only: Due to the limitations of the vehicle's battery capacity and the poor user experience of heating in winter, parking air conditioning is primarily cooling-only. It includes a refrigerant delivery system, cooling source equipment, terminal devices, and other auxiliary systems.

I used to drive long-haul trucks and would run the parking air conditioner all night. Regular batteries couldn't handle it, so I specifically installed a 200Ah deep-cycle lead-acid battery to solve the problem. This type of battery has a high depth of discharge, is durable, and affordable—just a few hundred bucks will do the trick. However, make sure to reserve enough power to start the vehicle. It's best to add a voltmeter to monitor the battery level and avoid running out of power unexpectedly. In summer, running the air conditioner consumes about 10 kWh per night, which translates to reserving at least 100Ah capacity in a 12V system. Now, I use a dual-battery system: the original vehicle battery starts the engine, while the parking battery powers only the air conditioner. No more waking up sweaty in the middle of the night!

What is the normal water temperature for a diesel car?

Diesel car water temperature is normal between 70°C and 95°C. Diesel cars operate at much lower temperatures than gasoline cars due to their characteristic of long-term operation at low speeds and high torque. However, the optimal temperature during normal driving is between 70~80°C. If the temperature exceeds 90°C and remains high, it indicates abnormal engine operation. Below is additional information: 1. When the engine temperature is too high, you can try removing the thermostat: The thermostat's function is to monitor the coolant temperature in the engine at all times, keeping the water temperature at an ideal range of 80 to 90 degrees, ensuring a good working temperature environment for the engine. 2. The thermostat is located on the water inlet pipe leading to the heat exchanger: It plays a role in maintaining a constant water temperature. Additionally, you can flush and clean the radiator and intercooler, using professional radiator cleaning agents during the process.

Why does the electric fan keep running after the car is turned off?

The fan in the car serves a cooling function. Therefore, after parking, if the temperature of the coolant is too high, the vehicle's computer will automatically calculate the fan's speed and duration. The higher the temperature, the longer the fan will run, thereby protecting the engine. There is no need to worry as this is a normal phenomenon. The fan can continue to run for about 10 minutes after the car is turned off. Relevant information is as follows: 1. Engine: If the engine coolant temperature at the moment of parking is higher than the acceptable soak temperature for the engine, the vehicle's computer will automatically calculate the fan's operating speed and duration, thus controlling the fan's operation automatically. The higher the motor's temperature, the longer the fan will run after stopping. When the motor coolant temperature drops below the soak temperature, the fan will shut off, thereby protecting the motor and extending its service life. 2. Cooling System: The car's cooling system is divided into a large circuit and a small circuit. When the engine is cold and the temperature is low, the engine needs to reach the operating temperature of 90° as quickly as possible. Therefore, the small circuit operates first. Once the temperature rises to normal, the thermostat opens, and the large circuit starts operating, allowing the antifreeze to flow through the radiator.

What Does a Car Platform Refer To?

An automobile platform can be understood as an original "template" for vehicles. This template encompasses fundamental components of a car, such as the chassis, body structure, electrical systems, and even production processes. In the early stages of the platform concept, vehicles sharing the same platform indeed had strictly interchangeable chassis components. However, with advancements in automotive technology, the concept of car platforms has evolved. Additional information: 1. Geely BMA Modular Architecture: The BMA platform is a new modular platform independently developed by Geely. Unlike the CMA platform co-developed by Geely & Volvo, which is allocated according to vehicle class, the BMA platform, standing for B-segment Modular Architecture, is designed for A-segment vehicles, suitable for A0 to A+ segments. Currently, several models such as the Geely ICON, Haoyue, Binrui, and Binyue are derived from this platform. 2. Toyota TNGA Architecture: TNGA stands for Toyota New Global Architecture. Strictly speaking, TNGA is a comprehensive value platform covering the entire automotive industry chain, including research and development, design, production, and procurement. Its primary function is to optimize and integrate resources within Toyota and its partner suppliers across corporate systems, R&D systems, production systems, and parts systems. 3. Volkswagen MQB Platform: The Volkswagen MQB platform, short for Modular Querbaukasten, translates to "Modular Transverse Matrix," representing a front-wheel-drive platform with a transverse engine layout. It is arguably the most significant and widely used automotive platform within the Volkswagen Group, currently encompassing numerous models under brands such as Volkswagen, Skoda, and Audi.

What Does Negative Offset Mean for Wheels?

Negative offset wheels are specialized rims designed for modified vehicles. Below is an introduction to negative offset wheels: 1. The centerline of these wheels is located outside the mounting surface between the axle and the wheel, giving them a distinct visual appearance compared to standard car tires. 2. The advantage of negative offset wheels lies in providing greater support during cornering. When the load-bearing surface of the wheel is inside the center reference plane, it is considered a negative offset wheel. 3. The benefits of negative offset wheels include widening the track width, which enhances vehicle stability and better utilizes the lateral support capabilities of high-performance tires.

How Long Does Black Roof Film Last

Black roof film generally lasts about three years. Here are the relevant details: 1. Objective factors: Strictly speaking, there is no accurate, standard, or uniform answer to this question, as it is influenced by many objective factors. The most important factor is the usual parking environment of the car. If the car is usually parked outdoors, exposed to wind and sun daily, the lifespan will certainly not be long. 2. Garage parking: However, if the car is usually parked in a garage, sheltered from wind and rain, the lifespan may extend to about five years. Additionally, the quality of the roof film itself also affects its durability. Good-quality material naturally lasts longer, while poor-quality material may start bubbling after just one or two years.

What are the methods for diagnosing clutch failures?

The methods for diagnosing clutch failures are as follows: 1. Incomplete disengagement: When the engine is idling and the clutch is depressed, there is a gear collision sound when shifting gears in place, making it difficult to engage. In severe cases, it may cause the engine to stall. If the driven disk is installed incorrectly on the front and back sides, causing the driven disk to still rub against the flywheel, it should be reassembled. If the driven disk is warped or deformed, causing it to still rub against the flywheel or pressure plate, the driven disk should be corrected. 2. Shudder during startup: When starting, the clutch does not engage smoothly and causes shaking. Uneven pressure distribution between the driven disks or inconsistent adjustment of the release levers can cause the clutch to shake due to inconsistent timing of pressure application. The clutch pressure springs should be replaced, and the release levers should be leveled. If the clutch lining has poor contact or the surface is hardened with adhesive, the clutch lining should be re-riveted. If the driven disk is warped, the clutch lining will have irregular contact during clutch engagement, and the driven disk should be corrected or replaced. 3. Abnormal noise: The clutch makes abnormal noises when disengaging or engaging. If the clutch pedal has no free play or insufficient free play, the free play of the clutch pedal should be adjusted. If the clutch friction plate is worn, causing the clutch to frequently be in a semi-engaged state, it can be resolved by adjusting the clutch free play. If the clutch lining is hardened, the lining should be cleaned or replaced.
