Should the oil filter be replaced when changing the engine oil?

What are the reasons for a new car failing the exhaust emission test?

The reasons for a new car failing the exhaust emission test include high sulfur and phosphorus content in gasoline, frequent vehicle start-stop and idling, incomplete combustion, and clogging of the three-way catalytic converter by carbon deposits and particulate matter in the engine. Solutions: Replace spark plugs; clean the contacts of the distributor and distributor rotor; adjust ignition timing; clean the air filter; use cleaning agents to clean the throttle body; clean the three-way catalytic converter and oxygen sensor, among other methods. Automotive exhaust emission testing standards: Automotive exhaust emission testing is based on whether the smoke opacity value meets the standards, and whether the emissions meet the standards is primarily determined by the vehicle's testing data, confirming compliance based on the smoke opacity value. If the exhaust emission values do not meet the standards, the annual inspection will not pass. The environmental standards for automotive exhaust emission testing are: the limit for carbon monoxide is 6.3g/km, and the total limit for hydrocarbons and nitrogen oxides is 2.0g/km.

Why does the B48 require spark plug replacement every 20,000 kilometers?

BMW B48 requires spark plug replacement every 20,000 kilometers to prevent insufficient ignition energy, which can lead to poor engine combustion, increased fuel consumption, and weak acceleration. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended at 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is advisable to follow the owner's manual. You can refer to the following maintenance standards for replacement: platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for spark plug replacement: Open the hood, lift the engine's plastic cover, and remove the high-voltage ignition wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Insert the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the correct firing order and secure the cover.

Does the VOGE 500AC have GPS?

VOGE 500AC comes with built-in GPS, allowing real-time location tracking via the APP. Introduction to GPS: The Global Positioning System, also known as the Global Satellite Positioning System, is a medium-range circular orbit satellite navigation system. It can provide accurate positioning, speed measurement, and high-precision time standards for most areas on the Earth's surface. Components of GPS: The GPS system mainly consists of the space segment (satellite constellation), the control segment (ground monitoring), and the user segment (equipment). Developed and maintained by the U.S. Department of Defense, the system meets the needs of military users anywhere on Earth or in near-Earth space for continuous and precise determination of three-dimensional position, three-dimensional motion, and time.

Automobiles do not require commercial insurance, and the necessity of purchasing commercial insurance varies from person to person. However, compulsory traffic insurance must be purchased. After obtaining compulsory traffic insurance, car owners can opt for commercial insurance if they desire more comprehensive coverage.

Basic insurance is further divided into vehicle damage insurance and third-party liability insurance. Coverage of Automobile Insurance: Vehicle damage insurance provides compensation for the loss of the insured vehicle; third-party liability insurance covers damages to objects outside the insured vehicle, such as pedestrians, public property, and other vehicles; passenger liability insurance compensates for injuries and property losses of people inside the insured vehicle; theft insurance provides compensation in case the insured vehicle is stolen.

Can You Add Water to a Car Battery?

You can add water to a car battery. Early electric vehicle batteries required the addition of electrolyte after prolonged use. Currently, electric vehicles (commonly) use maintenance-free lead-acid (gel) batteries, which, as the name suggests, do not require water replenishment. Battery maintenance methods: Frequent charging: Car batteries should be charged regularly. If left unused for extended periods, they will gradually self-discharge and eventually become unusable. Therefore, it's advisable to start the car periodically to charge the battery. Regular cleaning: Clean the battery terminals periodically and apply specialized grease to protect the wiring harness. Regularly inspect the battery components and connecting circuits. Avoid using electrical devices after turning off the engine: Do not use car electrical devices after the engine is turned off. Using the battery alone when the engine is not generating power can cause damage to it.
