Occasionally using 95 gasoline in a car designed for 92 will not cause harm, but long-term use of 95 gasoline can affect the ignition system, fuel injection system, and engine. 1. Octane Rating: Gasoline with a higher octane rating indicates better anti-knock performance. For hydrocarbons of the same group, smaller carbon numbers result in better anti-knock performance and higher octane ratings. For hydrocarbons with the same carbon number, the octane rating decreases in the following order: aromatic hydrocarbons > isoparaffins and isoolefins > normal olefins and naphthenes > normal paraffins. For different straight-run fractions from the same crude oil, lighter fractions have higher octane ratings. For fractions with the same boiling range from different crude oils, the chemical composition varies, leading to different octane ratings. 2. Gasoline Differences: 95 gasoline consists of 95% isooctane and 3% n-heptane, while 92 gasoline has an octane rating of 92 and a n-heptane rating of 8.

How to Check the Condition of a Car Compressor?

There are three main aspects to check the condition of a car air conditioning compressor: 1. Checking the compressor's sealing: Use a manifold gauge to test by connecting the high and low-pressure hoses of the manifold gauge to the compressor's high and low-pressure service valves, respectively. Start the engine and let it run at an idle speed of 2000r/min. 2. Measuring the resistance value of the compressor's electromagnetic clutch: First, remove the electromagnetic clutch coil from the compressor, then measure its resistance with a multimeter. Since the standard resistance of the electromagnetic clutch coil is (3.7±0.2)Ω, use the ohmmeter function of the multimeter to avoid measurement errors. If the multimeter needle does not move during measurement, it indicates that the electromagnetic clutch coil is open. If the measured value is less than 3.5Ω, it means the coil is short-circuited, open, or the electromagnetic coil should be replaced. 3. Checking the operating condition of the compressor: Whether the drive belt is broken or loose—if the drive belt is too loose, it will slip, accelerate wear, and fail to transmit power; whether there is noise inside the compressor; whether the compressor clutch is slipping.

What Causes Steering Wheel Shaking When Braking in a Car?

Steering wheel shaking when braking in a car indicates a fault in the braking system. The friction between the brake pads and brake discs causes the steering knuckle to vibrate, which in turn affects the tires, leading to the steering wheel connected to the steering gear also shaking. Reasons for steering wheel shaking include: 1. Shaking at idle: Loose steering wheel bolts or rubber bushings; 2. Shaking during driving: Imbalanced wheel alignment; 3. Shaking when turning the steering wheel: Power steering belt too loose or too tight; 4. Shaking when braking at high speed: Excessive or frequent braking, overheating of brake pads and discs, causing deformation when cooling; 5. Shaking on bumpy roads: Worn or loose tie rod ends or detached rubber bushings at joints. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, and aircraft, converting the force applied by the driver on the steering wheel's edge into torque, which is then transmitted to the steering shaft.

How much tax is generally levied on imported cars?

Import car tax calculation formula: Tariff = Duty-paid price × Tariff rate; Consumption tax = (Duty-paid price + Actual tariff) / (1 - Consumption tax rate) × Consumption tax rate; Value-added tax = (Duty-paid price + Tariff + Consumption tax) × VAT rate; The final tax to be paid is the sum of these three taxes, with the formula being: Car import tax = Basic tariff (15%) + Consumption tax (3%-20%) + VAT (13%). Taking an imported car worth 600,000 yuan (calculated based on a 2.0L displacement) as an example, the taxes to be paid are: 1. Tariff: Tariff = 600,000 × 15% = 90,000 yuan; 2. Consumption tax: Consumption tax = (600,000 + 90,000) / (1 - 5%) × 5% = 36,000 yuan; 3. Value-added tax: VAT = (600,000 + 90,000 + 36,000) × 13% = 94,400 yuan. 4. Total tax: The total tax to be paid is 90,000 + 36,000 + 94,400 = 220,400 yuan.

How to Check if Water Has Entered the Fuel Tank?

Check if the color of the engine oil is abnormal. If the engine oil turns milky white, it indicates that water has entered the fuel tank or engine. Below is an introduction to faults related to water entering the fuel tank, fuel tank, or engine crankcase: 1. Water in the fuel tank can cause rust, corrosion, and aging of the tank. If there is water in the fuel system, it can lead to decreased engine power, increased fuel consumption, vehicle shaking, and difficulty starting in winter. Symptoms of water in the fuel tank include difficulty starting, engine backfire, high idle speed, or insufficient power. 2. If water enters the fuel tank, in mild cases, the vehicle may be hard to start and lack acceleration power after starting; in severe cases, the vehicle may not start at all. 3. If water enters the engine crankcase, in mild cases, it can cause abnormal lubrication noise, reducing the service life of components such as crankshaft bearings, connecting rod bearings, camshaft bearings, and valve guides in the valve train. In severe cases, it can lead to crankshaft seizure, connecting rod breakage, or cylinder block cracking.

What does the wrench light mean?

The wrench-shaped light on the dashboard is called the maintenance reminder light. It automatically illuminates every certain mileage to remind the owner to perform timely maintenance, and does not indicate a fault with the vehicle. Therefore, it is recommended that the owner schedules maintenance as soon as possible. There are three types of exclamation mark warnings on the dashboard: 1. An exclamation mark inside a circle with brackets: Indicates brake pad wear or insufficient brake fluid. The solution is to release the parking brake and check if the brake fluid is low. If the light remains on, visit a repair shop to replace the brake pads. 2. An exclamation mark inside a triangle: Indicates an issue with the exterior lights. The solution is to check if any lights are malfunctioning. If the light remains on without any visible issues, it is advisable to visit a repair shop for further inspection. 3. An exclamation mark inside yellow brackets: Indicates a problem with tire pressure. The solution is to check if any tire is punctured or leaking air. If not, drive at low speed and find an auto repair shop, car care center, or roadside car wash, as they usually have air pumps to inflate the tires. After inflating, observe the dashboard. If the warning light persists, locate the settings in the vehicle's central console and recheck the tire pressure. The light should turn off once the pressure is normal.

Can a tire with peeled skin continue to be used?

Tire peeling needs to be judged based on the extent of the damage to determine whether it can continue to be used. If the area is large or the damage is deep, it should not be used further, as continued use may lead to bulging. Below are precautions for using car tires: 1. Bulging occurs: If bulging is observed on the tire, it must be replaced immediately; otherwise, it increases the risk of a blowout. 2. Tire lifespan: Tires are a crucial component of a car, directly affecting driving stability and safety. As rubber products, tires will age over time with prolonged use. Under normal circumstances, tires installed on a car can last for four years. 3. Regularly check tire pressure: During regular vehicle use, it is also important to frequently check the tire pressure. The tire pressure should neither be too high nor too low. If the pressure is too high, it reduces the contact area between the tire and the ground. If the tire pressure is too low, the tire may experience wave deformation during high-speed driving, increasing the risk of a blowout and potentially shortening the tire's lifespan.
