Can a Regular Battery Replace an Auto Start-Stop Battery?

Certainly, a regular battery cannot replace an auto start-stop battery. Below are the battery maintenance methods. Check the battery every six months: To keep the battery in optimal condition, it is best to have it tested at a 4S shop every six months to check its charging capacity. Generally, a battery's lifespan is around 3 years, and with good maintenance, it can last up to 4 years. However, as the battery ages, the intervals between checks should be shortened. Monitor the battery status indicator promptly: Many modern vehicles have a battery status indicator on the LCD display, which shows the battery's usage condition. When the battery voltage is insufficient, this indicator will flash as a reminder, prompting a thorough inspection. Therefore, it is important to pay attention to this indicator regularly. Additionally, there is a battery charge indicator on the battery itself, which can be observed directly on the battery.

Is it normal for fuel consumption to increase after cleaning the throttle body?

After cleaning, the fuel injector's spray diameter increases, leading to more fuel being injected per unit of time, which results in higher fuel consumption. This is a normal phenomenon. Below are specific methods to reduce fuel consumption: Lightly press the accelerator: When starting at low speeds, the car enters a peak fuel consumption zone. Therefore, gently pressing the accelerator during startup prevents excessively high RPMs and effectively reduces fuel consumption. Avoid high RPMs: Try to avoid unnecessary high RPMs, as fluctuating engine speeds can significantly increase fuel consumption. Regular maintenance: Change the engine oil and remove carbon deposits periodically. Avoid sudden braking: Anticipate road conditions in advance to avoid sudden braking, which not only improves driving safety but also saves fuel. For example, gradually slowing down before traffic lights and using inertia to coast.

What is Cylinder Pressure?

Cylinder pressure refers to the magnitude of compression force in the cylinder when the piston reaches the top dead center at the end of the compression stroke. Insufficient cylinder pressure indicates reduced cylinder sealing, which will lead to decreased engine power and difficulty in starting. If individual cylinders have insufficient pressure, it will cause unstable engine operation. For gasoline engines, the cylinder pressure typically ranges from 8 to 11 bar, while for diesel engines, it ranges from 12 to 16 bar. Specific values should be referenced according to the manual. Methods for checking gasoline engine cylinder pressure: 1. The engine temperature should be between 80 to 90 degrees, and the battery discharge level should not be less than 50%. 2. Remove all spark plugs and fully open the carburetor's throttle and choke valves. 3. Press the rubber tip of the cylinder pressure gauge firmly into the spark plug hole of the cylinder to be tested and hold it firmly. 4. Use the starter to rotate the crankshaft for 3 to 5 seconds at a speed of 150 to 180 rpm, and record the pressure indicated by the gauge. Repeat the measurement twice, and check the remaining cylinders in sequence. 5. If the cylinder pressure is below the specified value, add 20 to 30 grams of fresh engine oil to the top of the piston and recheck the pressure. If the pressure rises significantly, it indicates severe wear of the piston rings and cylinder. If the pressure remains the same as before, it suggests air leakage from the valves or cylinder gasket, and further inspection is required.

How Many Years Until a Private Car Used for Didi Chuxing is Scrapped?

For household 5-seat sedans and 7-seat SUVs, non-commercial small and micro vehicles have no usage lifespan. When the normal mileage reaches 600,000 kilometers, the state will guide them to be scrapped. In addition to the above vehicles, small and micro non-commercial passenger vehicles, large non-commercial sedans, and wheeled special machinery vehicles also have no usage lifespan restrictions. Commercial vehicles have a scrapping lifespan, as follows: Small and micro taxi passenger vehicles have a scrapping lifespan of 8 years, medium-sized taxi passenger vehicles have a scrapping lifespan of 10 years, and large taxi passenger vehicles have a scrapping lifespan of 12 years. Public bus passenger vehicles have a scrapping lifespan of 13 years, other small and micro commercial passenger vehicles have a scrapping lifespan of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping lifespan of 15 years. Micro commercial trucks have a scrapping lifespan of 8 years, light and large commercial trucks have a scrapping lifespan of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out an "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" and stamp it with the owner's seal. The registration desk will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping age. For vehicles that have not reached the scrapping age, after inspection and confirmation by the vehicle inspection desk that they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner will choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner will submit the "Modification Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the vehicle inspection desk for verification and signature. The license plates will be reclaimed, and the application will be submitted for approval according to regulations to complete the scrapping registration. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can hand over the scrapped vehicle to a local motor vehicle recycling company. Commercial vehicles converted to non-commercial use must be scrapped according to the original commercial vehicle's scrapping time. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer registration or deregistration of a motor vehicle, the original owner can apply to the vehicle management office to use the original license plate number when registering a newly purchased motor vehicle. The application to use the original license plate number must meet the following conditions: (1) The application must be submitted within six months after completing the transfer registration or deregistration; (2) The owner must have owned the original vehicle for more than three years.

What is the ETC discount?

Banks offer varying discounts to promote and encourage ETC applications. Starting from 2020, vehicles without ETC or not using ETC will not enjoy toll discounts. In the future, only one manual lane will remain at highway toll stations, requiring manual toll payment, and the efficiency will be lower compared to ETC lanes. ETC toll deduction principle: Highways will have one or more ETC lanes. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, computer networking technology is used for backend settlement with banks. This allows vehicles to pay tolls without stopping at toll stations, all based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and emissions by eliminating the need for vehicles to stop at toll stations, thus lowering pollution; Reduced wear and tear: Saves costs by minimizing frequent starts and stops, reducing vehicle wear and fuel consumption. Improved efficiency: ETC lanes can theoretically process vehicles 2-3 times faster, making traditional ETC more advanced, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, intercity transportation cards will be widely used in key city clusters, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year Plan" for comprehensive transportation development: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will promote ETC usage for trucks and explore deeper integration of ETC systems with smart transportation directions such as vehicle-to-vehicle communication and vehicle-to-infrastructure coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC. ETC usage precautions: The ETC transaction sensing range is 8 meters. If the vehicle ahead is stationary, maintain a distance of over 10 meters to prevent accidental toll payment for the vehicle ahead due to ETC device failure or absence. The recognized speed for ETC lane passage is 20 km/h. Excessive speed may prevent reading vehicle device information, leading to toll deduction failure. Unauthorized removal or movement of the OBU device, or detachment/loosening of the ETC electronic tag, will render the tag invalid. It can be taken to the bank where the ETC card was issued or a highway service center for inspection. If the detachment is not due to human error, reactivation is sufficient. When using a debit card linked to ETC, insufficient balance may cause toll deduction failure. Follow on-site staff guidance to use manual MTC lanes for cash or card payment. Thick windshields may cause poor signal reception. This is especially important for vehicles that have had windshield replacements after accidents or modified front windshields.
