Does a Faulty Fuel Pump Increase Fuel Consumption?

Replacing the fuel pump will not increase fuel consumption. The fuel pump only provides fuel pressure and does not affect fuel efficiency. Maintenance tips for the fuel pump are as follows: 1. Changing the oil for small gasoline engine water pumps: After one month of use or 20 hours of operation, change the oil once. Subsequently, change the oil every six months or after 300 hours of use. Ensure the engine is warm for quick and thorough oil drainage. 2. Maintenance of the air filter for small gasoline engine water pumps: A dirty air filter reduces the airflow into the carburetor. To prevent carburetor malfunctions, regularly maintain the air filter. Increase maintenance frequency under particularly dirty conditions. Do not use the water pump without an air filter. If dirt and dust are sucked into the engine, it can cause rapid engine wear. 3. Maintenance of the spark plug for gasoline water pumps: For the engine to operate normally, the spark plug must have the correct gap and be free of carbon deposits. Exercise caution when removing the spark plug cap. If the engine is running, the muffler will be very hot. Be careful not to touch the muffler.

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.
