What Are the Causes of Unstable Idle Speed in Car Engines?

What is the length of a fire truck?

The dimensions of the Dongfeng dual-rear-axle water/foam dual-purpose fire truck are: Length × Width × Height = 9550 × 2500 × 3400 (mm). Modern fire trucks are typically equipped with steel ladders, water guns, portable fire extinguishers, self-contained breathing apparatus, protective clothing, rescue tools, first aid equipment, and some may also carry large firefighting equipment such as water tanks, water pumps, and foam fire suppression systems. Vehicles generally come in standard, basic, mid-range, and high-end configurations, which respectively refer to: 1. Basic: Usually a simplified version without leather seats or power windows, lacking many electronic control functions; 2. Standard: Includes standard electric controls such as power windows, power steering, and air conditioning; 3. Mid-range: Slightly more advanced than the standard version, including all standard features and possibly additional features like airbags, sunroof, leather seats, power seats, and seat heating; 4. High-end: Higher than all the above configurations, often considered the flagship model of the vehicle.

Can Guowu Vehicles Still Be Licensed in Baoding?

Baoding officially implemented the China 6 emission standards on July 1, 2019. After July 1, models that do not meet the China 6 emission standards will be prohibited from sales, registration, and relocation. This means Guowu vehicles can no longer be licensed. Below is the relevant information: 1. Deadline for Licensing Guowu Vehicles in Baoding: The deadline for licensing Guowu vehicles coincides with the implementation date of the China 6 emission standards in Baoding. After July 1, 2019, Guowu vehicles can no longer be licensed. Some cities may have policies such as "Guowu vehicles invoiced before July 1 can be licensed until August 1." 2. Implementation of China 6 Standards: The China 6 standards, also known as the "National Sixth Stage Emission Standards for Motor Vehicles," include the "Limits and Measurement Methods for Emissions from Light-Duty Vehicles (China 6)" and the "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China 6)." Compared to China 6A, China 6B imposes stricter requirements on emissions of carbon monoxide, non-methane hydrocarbons, nitrogen oxides, and PM particulate matter. The data shows significantly stricter regulations, with China 6A serving as a transitional phase to China 6B.

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.
