What to Do If the Shock Absorbers Are Too Hard?

The solutions for excessively hard shock absorbers are as follows: 1. New car break-in period: Generally, the shock absorbers feel too hard because the car is new, and the components have not fully broken in yet. It is normal for the owner to feel that the shock absorbers are too hard, and the situation will improve after the break-in period. 2. Reduce tire pressure: The hardness of the shock absorbers can be adjusted by changing the tire pressure. However, the reduced tire pressure should still be within the normal range. This method can provide slight relief. 3. Upgrade to adjustable shock absorbers: Consult professionals and, if modifications are allowed, replace the shock absorbers with adjustable ones, such as coilover shock absorbers, which can also adjust height and damping. Additional information: 1. Telescopic shock absorbers are widely used in automotive suspension systems and can dampen both compression and extension strokes, known as double-acting shock absorbers. There are also new types of shock absorbers, including gas-filled shock absorbers and adjustable-resistance shock absorbers. 2. It is important to note that the hardness of car shock absorbers is designed based on the vehicle's specifications. Unauthorized modifications may affect the car's performance and safety and carry certain risks. If modifications are necessary, they should be performed at a reputable professional shop.

What is the reason for the hissing sound of a leaking lighter?

A lighter leaking gas with a hissing sound poses risks of explosion and combustion, so it should be placed in a safe location first. Below are the precautions for using lighters: 1. Do not attempt self-repair: The structure of gas lighters is very complex, especially the numerous springs and hairsprings inside. Due to space and hardness issues, they cannot be reassembled without specialized tools once disassembled. 2. Adjust the flame according to the manual: After obtaining the device, do not frequently adjust the flame. Once the flame is set, avoid further adjustments. When adjusting, pay close attention to the key points in the manual, and do not exceed 10 degrees at a time. It is particularly important to note that some adjustment mechanisms will render the device unusable if turned beyond 90 degrees. 3. Use clean gas for refilling: It is recommended to use specialized gas canisters. Although counterfeit products may still exist, major cities generally offer reliable options. If using ordinary gas canisters, ensure they are clean. A simple method is to press the nozzle and smell it before refilling; if odorless, the gas is suitable. 4. Avoid direct sunlight exposure: Direct sunlight on a gas lighter does not cause explosion but leads to the accumulation of a large amount of mixed gas in the tube. Upon ignition, the gas may break through the seal, causing permanent leakage due to seal failure.

What Are the Five Major Taboos of Turbocharging?

Turbocharging five major taboos are: 1. Stepping on the accelerator aggressively right after starting: Since the turbocharger is cooled by engine oil, and the oil's fluidity is poor when the engine is cold, high-speed operation of the turbocharger at this time can cause significant wear; 2. Lugging the engine with a manual transmission turbocharged car: Lugging can lead to severe engine damage and spark plug failure; 3. Excessive idling time: During idling, the engine speed is low, and the turbocharger speed is also low. The gas pressure inside the turbine and compressor is lower than that in the bearing housing, causing oil to leak towards the compressor and turbine at both ends; 4. Turning off the engine immediately after high-speed driving: When a running engine is suddenly shut down, the oil pressure drops rapidly to zero, interrupting oil lubrication and preventing the internal heat of the turbocharger from being carried away by the oil; 5. Not using high-quality oil as required: The turbocharger's speed usually exceeds 150,000 rpm, and most mass-produced cars use floating bearings for the turbo, making the selection of high-quality oil particularly important.

What is the minimum ground clearance of a fully loaded Golf?

The minimum ground clearance of a fully loaded Golf is 115mm. The minimum ground clearance of the Golf refers to the distance between the lowest point (excluding the wheels) and the supporting plane, which indicates the vehicle's ability to pass over obstacles such as stones and tree stumps without collision. A higher ground clearance in the Golf improves its off-road capability, but if the ground clearance is too high, the stability at high speeds may decrease. The Golf is built on Volkswagen's new MQB platform. The Golf's body dimensions are 4259mm in length, 1799mm in width, and 1476mm in height, with a wheelbase of 2637mm. Generally, the ground clearance of sedans ranges between 110mm and 150mm, while SUVs have a ground clearance between 200mm and 250mm. However, the Golf's ground clearance is not static; it depends on the load condition, so changes in ground clearance should be considered based on the Golf's load variations. When choosing a vehicle, ground clearance can be one of the reference factors. The decision should be based on the vehicle's intended use and the road conditions. For urban areas with well-paved roads, a vehicle with lower ground clearance can enhance stability and comfort. For long-distance travel or driving in areas with poor road conditions, a vehicle with higher ground clearance may be preferable to avoid scraping or damaging the undercarriage, considering the vehicle's off-road performance.

When Should the Engine Oil Be Changed for a New Car?

For a new car, the engine oil can be changed every 5,000 kilometers, while synthetic oil can extend the interval to 8,000 to 10,000 kilometers. In terms of time, even if the car hasn't driven 5,000 kilometers within six months, the engine oil should still be considered for replacement. Engine oil plays multiple roles in the engine, including lubrication and wear reduction, aiding in cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance of the base oil, making them an essential part of the lubricant.

What is the general warranty period for brake discs?

The warranty period for brake discs is generally one year, but it varies among different vehicle brands. As a wear-prone component, manufacturers offer different warranty terms for brake discs. Resurfacing or machining the surface of a brake disc reduces its service life, so replacement is recommended whenever feasible. The braking system consists of multiple components, primarily the brake disc, brake pads, and electronic braking system. The brake disc and pads function interdependently - failure of either component will result in braking failure. In addition to discs and pads, brake fluid maintenance is crucial, with recommended replacement intervals of 2 years or 40,000 kilometers.
