Is coasting in neutral or coasting in gear more fuel-efficient?

Between coasting in neutral and coasting in gear, coasting in gear is more fuel-efficient. Coasting in neutral: This involves shifting into neutral and letting the car glide forward by inertia. It's important to note that coasting in neutral is only applicable to automatic transmissions; manual transmissions should never coast in neutral. When a manual transmission is in neutral while moving, the transmission is still operating, and the lack of lubrication can cause wear. Coasting in gear: The engine is between low-speed fuel cutoff and high-speed fuel cutoff. At this point, the onboard computer detects that the car is idling, but the speed is higher than the engine RPM, so the computer will stop the fuel supply to the engine. Precautions for using a car engine are as follows: 1. Avoid driving in neutral: The engine itself has a deceleration fuel cutoff function, and driving in neutral is not conducive to fuel economy. 2. Pay attention to observation when using the vehicle: If you find oil on the ground, determine whether there is an engine oil leak and communicate with the car dealership promptly to eliminate safety hazards. 3. Do not turn off the engine immediately after high-speed driving or climbing a hill: For cars equipped with turbochargers, let the engine idle for 10 minutes before shutting it off. Turbocharged cars accumulate carbon deposits several times faster than naturally aspirated cars. 4. If water is mixed into or absorbed by the brake fluid: Replace or carefully filter it promptly; otherwise, it may cause insufficient braking pressure, affecting braking performance.

What are the precautions and common knowledge for car maintenance?

Here are the precautions for car maintenance: 1. Verify vehicle information: Check relevant details such as license plate number, chassis number, and in/out time to prevent billing errors. 2. Reclaim spare parts: If there are damaged parts, try to reclaim them to prevent unscrupulous businesses from substituting inferior products, which could pose risks to the car owner. 3. Labor hours: During repairs, labor costs are usually included. If billed separately, it may result in duplicate charges. For example, when replacing brake calipers, the brake pads must be removed, and the labor cost should be included in the repair fee. If the bill lists additional labor fees for caliper repair, you can question it. 4. Mileage: For serious car issues, the vehicle might need to stay at the repair shop for a while. Note the mileage to prevent dishonest mechanics from taking the car out for joyrides. Generally, test drives should not exceed 20 km. 5. Avoid unnecessary major repairs: Some shops may exaggerate minor issues or suggest unnecessary repairs to inflate costs. If unsure, ask for proof. 6. Check repair items: Understand the maintenance operations being performed. If they exceed the agreed service scope, consult the service advisor or mechanic. 7. Take excess oil: It's hard to buy the exact amount of oil needed. For example, if you buy 5 liters but don't need that much, take the excess with you. 8. Review the repair bill: Carefully check the settlement list before signing. Keep the receipt as proof of payment. 9. Utilize free inspection services: 4S shops and chain stores often offer free inspections. Periodic checks are essential. 10. Common areas for scams: Three filters (air, fuel, and oil filters) and cleaning services (intake tract, throttle body, and fuel injectors).

What Causes the Engine Warning Light to Illuminate in a Haval Vehicle?

There are primarily 7 reasons for the engine warning light to illuminate: Sensor malfunction: The sensors referred to here include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, which triggers the engine warning light. Fuel quality issues: If fuel and engine oil are not added as required by the manufacturer, it may cause engine wear, leading to the illumination of the warning light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockages can all cause poor combustion of the engine's air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the vehicle's intake, it may cause engine pipeline blockages, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can lead to intake problems. Exhaust issues: Exhaust system faults can also cause the engine warning light to illuminate. The rear oxygen sensor, catalytic converter, exhaust camshaft, and bearing failures are all potential causes of exhaust problems, with the catalytic converter being the most common. Using leaded gasoline, lead or silicon-containing lubricant additives, physical damage to the catalytic converter, and fuel supply system failures can easily lead to catalytic converter issues. Anti-theft system malfunction: If the vehicle's electronic anti-theft system malfunctions or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally, and the engine warning light will illuminate. If the engine warning light is on, follow these steps: First, check if the engine is running normally and if there are any issues such as shaking or black smoke. If so, avoid restarting the engine. Particularly, do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The vehicle will perform a self-check after powering on. Wait 5-10 seconds and observe if the warning light on the dashboard turns off. If the warning light remains on, visit a service station as soon as possible to diagnose the issue. The service station can use a portable diagnostic tool to read the fault codes, obtain fault information, and perform targeted repairs.

Does Engine Start-Stop Damage the Engine?

Engine start-stop does not damage the engine. The specific reasons are as follows: 1. Long lifespan of the start-stop function: Modern engines equipped with start-stop systems and the start-stop mechanisms themselves are designed to endure hundreds of thousands of cycles, essentially lasting as long as the vehicle itself. 2. Start-stop function protects the engine: The start-stop feature only halts engine operation, but the oil circulation system remains active. This means that even when the engine isn't running, oil continues to flow internally, ensuring better lubrication upon restart and providing additional engine protection.

Why is water dripping under the front of the Buick Excelle?

There are several reasons for water dripping under the front of the Buick Excelle: 1. Air conditioning condensation: When using the vehicle's air conditioning, condensation forms and flows down the exhaust pipe, causing water to accumulate under the chassis. 2. Radiator leakage: The radiator is located next to the engine, and if the connections are loose, it can lead to leakage, with the water dripping under the chassis. 3. Damage from scraping: While driving, accidental scraping of the chassis can cause leaks. Therefore, it's important to drive carefully, especially on rough roads, to avoid damaging your vehicle.

Can I Switch from Learning Manual to Automatic Transmission?

You can switch from learning manual to automatic transmission, and the change can be made before taking the Subject 2 exam. The following are the differences between manual and automatic transmissions: 1. Different operation difficulty: Manual transmission mainly relies on the driver stepping on the clutch to complete gear shifting; automatic transmission mainly relies on the hydraulic transmission principle of the torque converter to automatically shift gears. 2. Different shifting methods: Manual transmission involves manually moving the gear lever to change the gear engagement inside the transmission, altering the gear ratio. Automatic transmission does not require the driver to shift gears manually; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions.
