The consequence of insufficient engine oil is severe internal wear of the engine. In extreme cases, it can lead to complete engine failure beyond repair. When the engine oil is depleted, the oil warning light on the dashboard will flash, prompting a check of the oil level. Ignoring this and continuing to drive will result in dry or semi-dry friction between the engine cylinders and pistons, accelerating component wear. Here is relevant information: 1. Working Principle: Engine oil, or engine lubricant, is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. Engine oil is used for lubricating internal combustion engines. 2. Engine Oil: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption and cushioning for the engine.

What is the fuel tank capacity of the Great Wall Pao Diesel version?

The fuel tank capacity of the Pao-2022 model 2.0T Commercial Edition manual diesel four-wheel-drive Tea King Edition long box GW4D20M is 80L. The engine is equipped with a 2.0L turbocharged engine, and the transmission is a 6-speed manual transmission (MT). The drive type is front-engine four-wheel drive. The front suspension type is double-wishbone independent suspension, and the rear suspension type is leaf spring. In the same class, the fuel tank capacity of the Navara-2021 model 2.5L manual two-wheel-drive Comfort Edition QR25 is 73L. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity calibrated by the car manufacturer is from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is reserved to ensure that the fuel in the tank expands when the temperature rises without overflowing the tank's safety space. If the fuel is filled up to the tank opening during refueling, the actual refueling amount will be larger than the calibrated fuel tank capacity. If the owner wants to know the remaining fuel in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it means the fuel is almost empty, and when it is close to F, it means the fuel is sufficient.

What is the normal gap for piston ring ends?

Piston ring end gap is 0.4-0.6mm; side gap is 0.25-0.4mm; back gap is 0.35-0.55mm. Below is an introduction to measuring the three gaps of piston rings: End gap measurement: End gap refers to the gap at the opening when the piston ring is installed in the cylinder, to prevent the piston ring from seizing due to thermal expansion. When checking the piston ring end gap, place the piston ring flat in the cylinder, push it flat with the piston top, and then measure the gap at the opening with a feeler gauge. The first ring has a larger end gap than the other rings because it operates at higher temperatures. Side gap measurement: Side gap refers to the vertical clearance of the piston ring in the ring groove. Excessive side gap affects the sealing function of the piston, while insufficient side gap can cause the piston ring to seize in the groove. To measure, place the piston ring in the groove and use a feeler gauge. Back gap measurement: Back gap refers to the clearance between the back of the piston ring and the bottom of the piston ring groove after the piston is installed in the cylinder. It is generally expressed as the difference between the groove depth and the ring thickness. The back gap of a standard oil ring is relatively large. A common practice is to install the piston ring in the groove; if it sits below the ring land and can rotate freely without any resistance, it is considered suitable.

Can I go to another 4S store for maintenance?

Cars purchased from different 4S stores can be maintained at any 4S store (as long as the store carries the brand of the car). Daily vehicle maintenance is performed by the driver before, during, and after driving. Before driving, one should inspect the car to check if the lighting devices are damaged, if the body is tilted, if there are any leaks such as oil or water, and examine the condition of the tires, doors, engine hood, trunk lid, and windows. Things to note when going to a 4S store: Pay attention to verifying vehicle information: This mainly includes the vehicle repair unit (driver's name), license plate number, engine number, chassis number, entry time, and exit time (settlement time). The key details are the engine number and chassis number. The driver should carefully verify these numbers with those on the vehicle registration to prevent errors in input by the settlement staff. Otherwise, in case of an accident, there may be no recourse for complaints. Try to reclaim spare parts: The spare parts list details which parts were replaced during the current maintenance, along with the price of each part. The driver should check whether the listed parts exceed the scope of those that needed replacement in the maintenance project. Additionally, one can choose to reclaim the replaced parts whenever possible.

What's the matter with not being able to pay for traffic violations on 12123?

12123 traffic violation payment requires entering the confirmation payment page instead of the payment page. There may be several reasons for frequent payment failures: 1. System maintenance: Operations cannot be performed. Most software may undergo system maintenance during specific periods. It is recommended to try again later. This traffic management software may have bugs itself and still needs improvement. 2. Network issues: Check if there are network problems. The network may be unstable, and you can try reconnecting to the network. If there is an issue with the phone, you can try restarting it.

Where to Apply for a Replacement of a Lost Motor Vehicle Document?

If you lose your driver's license, you can apply for a replacement at the vehicle management office where the driver's license was originally issued or at any other vehicle management office outside the original issuing jurisdiction. When applying, you need to fill out an application form and submit the following documents and proofs: the identity proof of the motor vehicle driver; a written statement declaring the loss of the motor vehicle driver's license. After the motor vehicle driver receives the replacement driver's license, the original driver's license becomes invalid and must not be used anymore. Additional information: 1. Driving school registration time: To apply for a motor vehicle driver's license at a driving school, the registration process takes about half an hour to complete. After that, wait for the driving school's notification for a medical examination. Once the medical examination is completed, you can participate in the study for the motor vehicle driver's license subject one. After meeting the required study hours, you can take the exam. Other subjects should be completed in the same order. There is no need to repeat the medical examination within six months. 2. Time to obtain a motor vehicle driver's license: Under normal circumstances, it takes about 45 days to obtain a motor vehicle driver's license, with the maximum time not exceeding three years. This period starts after the completion of the motor vehicle driver's license subject one exam. If the time limit is exceeded, the qualification for the driver's license exam will be canceled, and you will no longer be able to take the exam.

What is the Difference Between Hybrid and Dual Engine?

Hybrid generally refers to gasoline-electric hybrid vehicles, which are equipped with both a conventional fuel engine and an electric motor. Dual Engine refers to vehicles equipped with two power engines: a fuel engine and an electric motor. The main differences between Hybrid and Dual Engine are as follows: 1. Engine Aspect: Hybrid generally refers to gasoline-electric hybrid vehicles. They feature both a traditional fuel engine and an emerging electric motor, with both operating under optimal conditions to achieve efficient energy utilization. Dual Engine, on the other hand, has two power sources—an engine and an electric motor—equivalent to having two power engines. 2. Power Source Aspect: Hybrid vehicles typically use a conventional internal combustion engine (diesel or gasoline) and an electric motor as power sources. Some engines may be modified to use alternative fuels such as compressed natural gas, propane, or ethanol. Dual Engine vehicles possess both an engine and an electric motor as power sources, significantly enhancing performance while greatly reducing fuel consumption. This technology balances tradition and the future, effectively implementing energy-saving and emission-reduction measures. 3. Driving Mode Aspect: Hybrid vehicles utilize both gasoline and electric driving modes. The advantage is that when starting or stopping, the vehicle relies solely on the electric motor. The engine does not engage until a certain speed is reached, ensuring the engine always operates under optimal conditions, delivering strong performance with very low emissions. Additionally, the electricity is generated by the engine, requiring only refueling. Dual Engine vehicles are powered by the electric motor during startup and low-speed driving, while the engine takes over during high-speed and acceleration phases. During normal deceleration, the vehicle can also recover excess energy and store it in the battery, eliminating the need for external charging.
