Can You Still Drive with a Chassis System Malfunction?

It is not advisable to continue driving with a chassis system malfunction. Once a vehicle's chassis develops a fault, the driver must promptly inspect and repair it. Continuing to operate a vehicle with a faulty chassis system compromises safety during driving. Below is additional information about a vehicle's chassis system: 1. Components: The chassis system is another critical part of a vehicle, following the engine. It contains many essential components, such as the transmission system, running gear, steering system, and braking system. Driving a vehicle with a faulty chassis can easily cause these components to fail, leading to unpredictable dangers. 2. Timely Repair: The primary function of the chassis is to support and install the vehicle's engine and its various parts and assemblies, ensuring normal operation. Therefore, any chassis malfunction should be repaired immediately.

Is the touch-up paint at 4S shops the same as at repair shops?

No, it's not the same. Compared to repair shops, 4S shops have advantages mainly in terms of materials, equipment, and quality assurance. Due to more standardized operating procedures, the touch-up paint effect at 4S shops is indeed slightly better than at most repair shops. Below are the specific details: 1. Different paint materials: Both 4S shops and repair shops use what's called "automotive refinish paint." Whether it's a 4S shop or a repair shop, the paint used cannot actually be called "original factory paint." Only the paint applied when the manufacturer is producing and building the vehicle can be called "original factory paint." From a professional perspective, the paint provided by paint manufacturers to automobile OEMs is called "automotive paint," while the paint provided to 4S shops and repair shops is called "automotive refinish paint." 2. Different touch-up paint equipment: 4S shops have better sanding equipment, which is more efficient. 4S shops mainly use "panel spray dry sanders," while some smaller auto repair shops still use manual wet sanding. Comparing the two, dry sanding is much more efficient, capable of sanding 10 square meters per hour, whereas wet sanding can only sand 4 square meters per hour.

What are the components of automotive antifreeze?

Automotive antifreeze is primarily composed of ethylene glycol. Currently, over 95% of antifreeze used domestically and internationally is water-based ethylene glycol antifreeze. Compared to tap water, ethylene glycol is notably characterized by its antifreeze properties, whereas water cannot prevent freezing. Additionally, ethylene glycol has a high boiling point, low volatility, moderate viscosity that changes minimally with temperature, and excellent thermal stability. Antifreeze prevents the coolant from freezing when the vehicle is parked in cold winter conditions, which could otherwise cause the radiator to crack or the engine block to freeze. Many people believe that antifreeze is only necessary in winter, but in fact, antifreeze should be used year-round. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year.

Why is the antifreeze decreasing more and more?

The reasons for the decreasing antifreeze: 1. Damage to the radiator cylinder gasket; 2. Loose connections at the overflow tank, water pump joint surface, and various pipelines of the cooling system; 3. Evaporation under high temperatures. If there is a lack of antifreeze, the primary issue is the loss of effective cooling, which can easily lead to overheating during high-speed operation. Additionally, the viscosity of the engine oil will decrease, leading to wear and tear on engine components over time. The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. It prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking.

Does Antifreeze Get Consumed?

Antifreeze does get consumed over time. It is considered a consumable item, and under continuous high temperatures, some degree of evaporation is inevitable. Additionally, antifreeze loss can occur due to leaks. Damaged radiator gaskets, overflow tanks, loose connections at the water pump interface, or other cooling system pipe fittings may lead to antifreeze leakage. In such cases, it is essential to visit the nearest auto repair shop promptly for repairs. Insufficient antifreeze can have varying degrees of negative effects. If the antifreeze level is too low (below the MIN mark), the cooling efficiency will be significantly reduced. This can easily lead to overheating (excessive temperature) during high-speed operation, and the viscosity of the engine oil will also decrease. Over time, this can cause wear and tear on engine components.

How Much Does Turning on the Air Conditioner Reduce the Range of an Electric Vehicle?

When driving an electric vehicle at a constant speed of 60km/h, the theoretical range with the air conditioner ON will decrease to 80% of the range when the air conditioner is OFF. Here is some extended knowledge about pure electric vehicles: 1. Consumption: Since pure electric vehicles do not have an engine, they cannot utilize the residual heat from the engine to provide warm air like fuel-powered vehicles. Instead, the heating system in pure electric vehicles relies on a high-voltage resistance heating module (PTC heater) installed in front of the air conditioning blower. This module converts electrical energy into thermal energy to supply warm air to the cabin, similar to the principle of a hair dryer. Therefore, keeping the heater on while driving consumes a significant amount of battery power, approximately 5 kWh per hour. 2. Compressor: Using the air conditioner for cooling in summer is much more efficient. The cooling system in pure electric vehicles also utilizes a compressor, but the compressor's power is only 2-3 kW. Once the cabin temperature stabilizes, the compressor's power reduces to around 1 kW. As a result, running the air conditioner for cooling in summer consumes about 2 kWh per hour. Based on this calculation, a fully charged battery can still provide a range of over 210 kilometers even with the air conditioner on.
