What to Do When Car Shock Absorbers Are Too Hard?

Here are the solutions for hard car shock absorbers: 1. Reduce tire pressure: Lowering tire pressure can help improve ride comfort to some extent, but do not reduce it too much, as it may damage the tires and pose safety risks to passengers. 2. Use seat cushions: The direct effect of overly hard shock absorbers is a bumpy and uncomfortable ride. Using car seat cushions can help improve this to a certain degree. 3. Adjust or replace shock absorbers: Consult a professional for advice. If modifications are allowed, consider replacing them with softer shock absorbers, such as coilover shock absorbers.

Under What Conditions is the Car's Water Temperature Normal?

The water temperature gauge ranges from 0-130°C, with the normal temperature being the central 90°C. After the vehicle starts, the water temperature rises quickly. Once the pointer reaches the central position, the water temperature no longer increases. Generally, it is best to start driving when the temperature reaches the middle position. Specific details are as follows: 1. The data on the water temperature gauge is only approximate, and the actual temperature may differ from what is displayed. The actual water temperature can be read using a car repair computer or a private car's OBD diagnostic tool displayed on a mobile phone. Due to different design philosophies, the normal operating temperatures of engines from different manufacturers vary. Generally, as long as the gauge does not exceed the red line, it is acceptable. 2. Additionally, if the engine water temperature is too low, it can increase fuel consumption and wear, so the engine should not operate at low temperatures for extended periods. If inspection reveals a cracked water hose or radiator, the aforementioned methods will not help and may instead cause more coolant loss and a faster rise in water temperature. In such cases, it is recommended to stop driving immediately and call for assistance.

How to Check the Condition of a Battery

Methods to check the condition of a battery are as follows: 1. Perform a startup test on the car or electric vehicle by using the key to ignite. If the vehicle fails to start after inserting the key and it hasn't been parked or discharged for a long time, it can be preliminarily judged that the battery is severely aged and needs replacement. 2. After driving the car normally for a period, if it won't be used for some time, conduct a discharge test. Turn the key to the circuit-on position and then turn on the headlights. If the headlights go out within one or two days, it indicates battery aging. During the car startup, observe electronic devices like the radio—if the sound fluctuates between loud and soft, it suggests unstable battery output. 3. Open the front engine hood and check the battery's two electrodes for white crystalline deposits. If there are many, it indicates severe battery sulfation, requiring replacement. Also, check the production date and specifications on the battery cover. If the production date is ten years or older, it is recommended not to use it. 4. Use a multimeter to test the battery voltage under no load. The voltage should be 12V and stable. If the voltage is too low or fluctuates, it indicates battery aging. 5. Connect the multimeter to the battery's positive and negative terminals, start the car, and turn on the air conditioner. Observe the voltage reading. If the voltage drops significantly, it indicates battery aging.

What Does Curb Weight Mean?

The curb weight of a car, commonly referred to as the "empty vehicle weight," is the weight of the car when it is fully equipped according to the manufacturer's technical conditions (such as spare tires, tools, etc.) and all fluids are filled. This is an important design indicator for automobiles. The indicator must be both advanced and practical. It is closely related to the car's design level, manufacturing level, and industrialization level. Under the same vehicle model conditions, the better the design method, the higher the production level, and the higher the industrialization level, the lower the curb weight will be. The curb weight is also commonly known as the vehicle's self-weight. Its standardized definition is: the weight of the car when it is ready to drive under normal conditions (with 90% fuel in the tank), including onboard accessories (spare tire, tools, etc.), and the driver's weight of 68 kg plus luggage weight of 7 kg. The curb weight is also an important parameter affecting the car's fuel consumption. Because the vehicle's fuel consumption is directly proportional to the curb weight, meaning the heavier the car, the more fuel it consumes. For example, for a small car, if the curb weight increases by 40 kg, it will consume 1% more fuel. Curb weight affects the manufacturing cost and fuel economy of vehicles like water trucks. Currently, the main themes for specialized vehicles are lightweight, environmental protection, energy saving, and safety. By optimizing structures, using high-strength steel components, aluminum alloys, and non-metallic composite materials, the curb weight can be minimized to increase cargo or passenger capacity and save fuel. Even semi-trailers and cement mixers now use high-strength steel for their upper structures to further enhance the carrying capacity of water trucks. In the future, lightweight, environmental protection, and energy efficiency will be the direction of automotive development, continuously reducing curb weight (typically, a 10% reduction in curb weight can lower fuel consumption by 6%-8% and CO2 emissions by 8%), thereby improving the ratio of vehicle load capacity to curb weight. When determining a vehicle's load capacity, the following factors should be considered: it must align with the vehicle's purpose and usage conditions; the load capacities of various vehicle models should be reasonably graded to facilitate product serialization, generalization, and standardization. The extent and feasibility of modifying existing production equipment and lines should also be considered. Vehicle self-weight utilization coefficient. This is an important evaluation indicator (for trucks). It refers to the ratio of the vehicle's total mass to its dry weight. The dry weight of a vehicle is the empty weight without coolant, fuel, oil, spare tire, tools, and accessories. Clearly, under the same load capacity, the smaller the dry weight, the higher the vehicle's mass utilization coefficient, and the higher its transportation efficiency. The mass utilization coefficient of the EQ1092F is around 1.22. With advancements in automotive material technology, manufacturing, and design, the mass utilization coefficient of vehicles has an increasing trend. Axle load distribution of the vehicle. This refers to the proportion of the vehicle's mass distributed on the front and rear axles. The principle of axle load distribution is determined based on uniform tire wear, the vehicle's main performance needs, and its layout type. To ensure uniform tire wear, it is generally desired that each tire bears roughly equal load when fully loaded. For example, for a 4×2 vehicle with a single rear tire, the desired axle load distribution is 50% for both front and rear axles, while for a vehicle with dual rear tires, the desired distribution is 1/3 and 2/3 for the front and rear axles, respectively. In reality, these can only be approximately met. For instance, general trucks typically have a front axle load distribution of around 28-30%.
