Reasons for Engine Burning Oil

Engine burning oil is caused by worn or aged valve seals or excessive piston clearance. Below are relevant introductions regarding engine burning oil: 1. Symptoms of engine burning oil: The exhaust pipe emits blue smoke during startup or during normal engine operation, while no pulsating blue smoke is observed at the oil filler port, or the exhaust pipe emits blue smoke, and at the same time, pulsating blue smoke is emitted from the oil port. 2. Solutions for engine burning oil: Cold engine burning oil: When the car temperature has not fully warmed up, the engine exhaust pipe emits a lot of blue smoke, but it returns to normal after the engine warms up. This phenomenon is caused by aging valve seals. Replacing the valve seals can solve the problem. If the engine burns oil when hot and the situation is not severe (for safety, a cylinder pressure test can be performed first), the oil pan can be directly removed, the piston taken out, and the piston rings replaced.

Do Seat Covers Affect Airbags?

Seat covers can affect airbags. Here is relevant information about airbags: 1. Introduction to airbags: The electronic control safety airbag system is a passive safety protection system. When used in conjunction with seat belts, it provides effective collision protection for occupants. In the event of a car collision, airbags can reduce head injuries by 25% and facial injuries by approximately 80%. 2. The protective principle of airbags: When a car is subjected to a certain level of collision force, the airbag system triggers a chemical reaction similar to the detonation of a small amount of explosive. The airbag hidden inside the car inflates and deploys instantly, positioning itself between the occupant's body and the car's interior components before impact occurs. When the body comes into contact with the airbag, the airbag begins to deflate through the pores on its surface, cushioning the impact and ultimately reducing the severity of injuries to the occupants.

Which Symbol Represents the China V Emission Standard?

The symbol for the China V emission standard is: China V. Below is relevant information about the national vehicle emission standards: 1. Definition of national vehicle emission standards: Vehicle emission standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. Regulations on national vehicle emission standards: Global vehicle emission standards coexist, primarily divided into European, American, and Japanese systems. The European standard testing requirements are relatively lenient and are widely adopted by developing countries. Since most passenger car models in China are introduced from Europe, China largely follows the European standard system. China's emission standards have progressed annually: On July 1, 2004, the China II emission standard was implemented nationwide; on July 1, 2007, the China III emission standard was implemented nationwide. In 2013, Beijing implemented the "China IV Emission Standard for Motor Vehicles" for all newly registered vehicles. The China V standard was implemented nationwide on January 1, 2017. On June 22, 2018, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine issued the "Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI)", which came into effect on July 1, 2019.

Differences Between Mineral Oil and Full Synthetic Oil

Mineral oil and full synthetic oil have certain differences, mainly reflected in four aspects: price, viscosity, service life, and production method. The following are the main distinctions between the two: 1. Price difference: Mineral oil is refined from natural substances, generally with lower production costs; whereas full synthetic oil is chemically synthesized, resulting in higher production costs, hence a significant price gap naturally exists between them. 2. Viscosity difference: Mineral oil is more affected by temperature changes, exhibiting poor fluidity at low temperatures. In contrast, full synthetic oil is less influenced by temperature variations and can maintain good fluidity even at very low temperatures. 3. Service life difference: Under the same working conditions, full synthetic oil has a much longer service life compared to mineral oil. 4. Production difference: Mineral oil is manufactured by adding certain additives to petroleum-refined mineral oil as a base, while full synthetic oil is entirely synthesized, fundamentally differing from mineral-based oil.

How to Check if a Vehicle Has an ETC Account?

Currently, there is no online channel to check whether your new car has been registered for ETC by the previous owner. You can only inquire at a bank branch by presenting relevant documents such as your ID card and vehicle license. ETC Usage Precautions: The ETC transaction sensing range is 8 meters. When the vehicle in front stops, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters to avoid automatic payment for the front vehicle. The recognition speed for ETC lanes is 20 km/h. If the vehicle speed is too fast, the system may fail to read the vehicle's device information, resulting in a failed transaction. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, may cause the electronic tag to become invalid. In such cases, you can take it to the bank where the ETC card was issued or to the highway service office for inspection. If the tag becomes loose or falls off due to non-human factors, it only needs to be reactivated.

Can I drive without carrying the vehicle license in the car?

You cannot drive without carrying the vehicle license in the car. Below is some information about the driver's license: 1. Driving a motor vehicle: When driving a motor vehicle on the road, you must display the vehicle license plate, place the inspection qualification mark and insurance mark, and carry the vehicle license with you. The vehicle license plate should be displayed clearly and completely as required, and must not be intentionally obscured or damaged. 2. Vehicle license plate: No unit or individual may confiscate or detain the vehicle license plate. It is prohibited to assemble a motor vehicle or alter the registered structure, construction, or features of a motor vehicle without authorization.
