What is the standard for engine oil consumption in cars?

The national regulatory standard is 0.3 liters per thousand kilometers. Here are the reasons for excessive oil consumption: 1. Piston ring wear or damage, misaligned or incorrectly installed piston rings: When piston rings wear out, their elasticity weakens, reducing the pressure on the cylinder walls and diminishing their oil-scraping effect. Additionally, wear between the piston rings and ring grooves increases side and back clearances, leading to more oil leakage. This is especially true when the oil ring is damaged, causing oil leakage to multiply. Moreover, misaligned or incorrectly installed piston rings create a pathway for oil splashed onto the cylinder walls to enter the combustion chamber, significantly increasing oil consumption. 2. Excessive clearance between the piston and cylinder wall: When the clearance between the piston and cylinder wall is too large or the cylinder becomes tapered or oval, the piston rings, piston, and cylinder wall cannot fit tightly. This allows splashed oil to leak into the combustion chamber and burn, drastically increasing oil consumption. 3. Use of low-viscosity oil: Low-viscosity oil is more prone to leakage and forms thinner oil films, making it easier to burn. Additionally, low-viscosity oil has a higher evaporation rate. 4. High engine speed: The higher the engine speed, the greater the centrifugal force on the crankshaft and connecting rods, causing more oil to be splashed onto the cylinder walls. The oil ring may not have enough time to scrape off this oil, leading to more oil entering the combustion chamber and burning. Furthermore, increased oil circulation raises the temperature of the oil in the oil pan, thinning the oil. Additionally, more atomized oil is carried out through the crankcase ventilation port. As a result, oil consumption increases.

Can ETC cards be recharged via WeChat?

ETC cards can be recharged via WeChat. To recharge ETC via WeChat, the mobile phone needs to support NFC or use an official Bluetooth card reader for recharging; after entering WeChat, select [Me] - [Payment] - [City Services]; under [Highway Services], choose the [Highway ETC] option; click [ETC Recharge] and follow the prompts to complete the payment and other operations. Precautions for using ETC: The ETC transaction sensing range is 8 meters. When encountering a vehicle in front that has stopped, to prevent the vehicle in front from having a faulty ETC device or no ETC device at all, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The speed limit for ETC lane recognition is 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to become invalid. It can be sent to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also result in a failed fee deduction. Follow the guidance of the on-site staff to go to the manual MTC lane and use cash or card for passage. Poor sensing due to excessively thick car windshield. Especially vehicles that have had their windshields replaced after an accident or vehicles with modified front windshields need to be careful.

What kind of glue can be used to repair car tires?

Hot vulcanizing glue and quick-drying glue can be used to repair car tires. Here is a detailed introduction about car tires: 1. Overview: Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help to mitigate the impact during driving, ensuring good ride comfort and smooth driving. 2. Function: They ensure good adhesion between the wheels and the road surface; improve the vehicle's traction, braking, and off-road capability; and bear the weight of the car. The important role of tires in vehicles is increasingly being recognized by people.

What are the causes of engine oil pressure failure?

Reasons for low oil pressure failure: 1. Insufficient oil quantity leading to low oil pressure. 2. Oil pump wear or damage causing low oil pressure. 3. Engine overheating leading to oil aging and deterioration resulting in low oil pressure. 4. Suction filter blockage causing low oil pressure. 5. Pressure relief valve damage or improper adjustment leading to low oil pressure. 6. Oil cooler leakage resulting in low oil pressure. 7. Oil viscosity being too low causing insufficient pressure. 8. Malfunction of oil pressure display device leading to low oil pressure.

What does light hybrid mean for small cars?

Light hybrid for small cars refers to vehicles being light hybrid electric vehicles. Below is a related introduction to light hybrid: 1. Hybrid system: The 48V light hybrid system is not simply an upgrade from 12V to 48V voltage. It is an addition—retaining the original 12V system while adding a 48V light hybrid system as an auxiliary. 2. Benefits: The greatest advantage of the 48V light hybrid system lies in its optimization during engine start-stop, acceleration, braking, and other conditions, which can directly save a significant amount of fuel. The higher voltage drives a more powerful start-stop motor, making it easier to turn the engine crankshaft, resulting in shorter system delays and reduced jerkiness.

What are the conditions for declaring a car as a total loss?

When the actual repair cost of the insured vehicle reaches or exceeds 80% of its actual value, and both the insurer and the insured agree through negotiation, the vehicle can be declared a total loss. Here is detailed information about auto insurance: 1. Overview: Auto insurance, also known as motor vehicle insurance or car insurance, is a type of commercial insurance that covers personal injuries or property damage caused by natural disasters or accidents involving motor vehicles. 2. Additional Information: Auto insurance is a category of property insurance and is relatively new in the field of property insurance. In its early stages, auto insurance primarily covered third-party liability and gradually expanded to include risks such as collision damage to the vehicle body.
