When the fuel pump fuse is not blown but there's no power, check whether the wiring plug is loose or if there is water ingress causing a short circuit. Additional information: 1. Fuel Pump: As the most fundamental component in the engine fuel supply system, the fuel pump is responsible for drawing fuel from the fuel tank during engine operation and delivering it continuously to the engine at a certain pressure through the fuel supply line. The high-pressure fuel pump then performs secondary pressurization, supplying a measured amount of fuel to each cylinder according to the engine's firing order. 2. Fuse: In the automotive electrical system, many electrical devices are connected by wires of different colors, among which the most important should be the fuse. The term 'fuse' is a customary name, referred to as a 'fusible link' in national standards. The function of a fuse is to protect the circuit (wiring) and electrical devices.

Why Does the Car Shake Violently After Refueling?

The reasons for car shaking after refueling may include: 1. Poor fuel quality, such as high water content or excessive impurities, leading to abnormal engine operation and shaking; 2. Fuel pump malfunction due to internal or wiring issues, causing overheating, poor operation, short circuit, or burnout, resulting in insufficient or stopped fuel supply; 3. Clogged fuel filter or excessive foreign particles, obstructed fuel supply, or issues with the fuel line such as blockage, rupture, corrosion, or deformation (due to scraping or collision, etc.); 4. Faulty fuel injector, abnormal fuel injection, or injector clogging (due to foreign particles or impurities).

Continental or Michelin for the 10th-gen Civic?

Even within the Michelin brand, different tread patterns represent different product positioning. If you prioritize tire comfort, noise reduction, and mileage, we recommend choosing the PRIMACY-3-ST, a high-end comfort-oriented tire tread pattern. If you place more emphasis on tire grip and handling, the Pilot-sport4 is suggested, a tire designed for entry-level sports cars and mid-to-high-performance sedans. Below is relevant information about tires: 1. Purchasing tips: Generally, when selecting tires, pay attention to the speed rating, load index, production date, and size. If the tire's production date is three years old, do not purchase it, as tires degrade when stored unused. 2. Timely replacement: Replace tires every four years, even if the mileage driven within those four years is minimal. Since tires are rubber products, they will age over time, and not replacing them for extended periods can pose safety hazards.

Can I still drive if my driver's license has expired and I haven't renewed it?

If your driver's license has expired and you haven't renewed it, you cannot drive. Otherwise, you may be treated as driving without a license, so you should renew it as soon as possible. Time regulations: If the expiration is less than one year, you can renew it normally; if it has been expired for more than one year but less than three years, the license will be revoked, but you can renew it by passing the subject one exam; if it has been expired for more than three years, the license will be invalid and cannot be renewed. Penalties for driving with an expired license: You must not drive a motor vehicle during the expiration period, otherwise you may be treated as driving without a license. If your driver's license has been expired for less than one year, you can renew it at any time, but if you drive on the road, you will face a fine of 200 yuan. If your driver's license has been expired for more than one year without renewal, the traffic management department will revoke it according to the law. If the expiration is less than three years, the driver must retake and pass the subject one exam to restore their driving qualification. If they drive on the road during this period, they will face a fine ranging from 200 to 2000 yuan. If the driver's license has been expired for more than three years, it will be completely revoked. The driver must retake the driver's license exam if they want to drive again. Otherwise, driving on the road will be treated as driving without a license, resulting in a fine of 2000 yuan and administrative detention for up to 15 days.

Is there an age limit for driving? What is the maximum age one can drive until?

Individuals aged 60 and above are prohibited from driving large buses, tractors, urban buses, medium-sized buses, large trucks, trolleybuses, and trams. Those holding a driver's license for large buses, tractors, urban buses, medium-sized buses, or large trucks must visit the vehicle management office at the place where their motor vehicle driver's license was issued to exchange it for a license that permits driving small cars or small automatic transmission vehicles. Individuals aged 70 and above are prohibited from driving low-speed trucks, three-wheeled vehicles, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, and wheeled self-propelled machinery. Those holding a driver's license for ordinary three-wheeled motorcycles or ordinary two-wheeled motorcycles must visit the vehicle management office at the place where their motor vehicle driver's license was issued to exchange it for a license that permits driving light motorcycles. Article 11 states that applicants for a motor vehicle driver's license must meet the following requirements: (1) Age conditions: 1. Applicants for small cars, small automatic transmission vehicles, or light motorcycles must be between 18 and 70 years old. 2.

Does a Turbocharger Require Maintenance?

Turbochargers do require maintenance. For turbocharged models, in addition to using high-quality engine oil, it's also essential to regularly clean or replace the air filter and oil filter. This is because the clearance between the turbocharger's rotating shaft and its bushing is extremely small. If the air drawn into the engine or the engine oil contains impurities, it can accelerate wear between the turbine components, leading to operational issues, damage to the turbocharger, oil leaks, and other problems. Key points to note: Air filters and oil filters must effectively remove impurities to ensure the turbocharger remains clean and functions properly.

Can ETC be used without installation?

ETC cannot be used without installation. According to the "Rules for the Use of Non-Stop Fast Passage Systems," ETC requires installation and the insertion of a card into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card. When the ETC card is inserted into the OBU device, a prompt sound will indicate that the device is activated. Without the card inserted, the device remains in a dormant state and cannot recognize vehicle information at toll stations. Therefore, ETC cannot be used without installation or card insertion. ETC is a non-stop electronic toll collection system, also known as an automatic road toll system. It is a specialized method for toll roads, commonly seen on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's windshield-mounted electronic tag and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks, allowing vehicles to pass toll stations without stopping. This is based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions by avoiding stops at toll stations. Cost-saving: Reduces vehicle wear and fuel consumption by minimizing frequent starts and stops. Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" explicitly states the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also sets a target of "achieving a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of comprehensive transportation development during the 13th Five-Year Plan. Future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC usage for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.
