What are the new regulations for vehicle annual inspections in 2021?

2021 adjustments to vehicle annual inspection items are divided into two parts: private cars and freight vehicles, with specifics as follows: Private car section: Private cars now include a "safety defect recall" step in the online inspection process. If a vehicle has safety issues and is subject to a manufacturer recall, the inspector will notify the owner about the recall status. The new regulations clarify and relax the exterior inspection standards, allowing modifications to the grille, pedals, roof rack, bumper, and wheel hubs during the visual inspection. Freight vehicle section: Freight vehicles implement a "three additions, six reductions" policy, removing six original inspection items and adding three new ones. The newly added inspection items are tire tread depth, wheel lifting device, and wheelbase. The six removed items are noise, speedometer, suspension efficiency, fuel economy, power performance, and headlight offset.

Is it necessary to perform an oil change immediately when it's due?

An oil change is indeed required immediately when it's due. Here are the specific details: Reasons: If the oil change is overdue, it should be replaced as soon as possible after driving approximately 3,000 to 5,000 kilometers. Expired oil is not beneficial for the engine. Oil is highly absorbent and over time, it absorbs moisture from the air, leading to oil degradation and a decline in performance. Precautions for oil change maintenance: Replace both the oil and the oil filter simultaneously, as this helps extend the engine's lifespan. When removing the oil filter, use a filter wrench or appropriate tools to prevent damage to the connecting threads. Do not mix single-grade and multi-grade oils. Different brands of oil can be temporarily mixed, but long-term mixing should be avoided. Do not use machine tool oil or other non-engine oils in car engines, as this can cause premature wear or damage to the engine.

What are the effects of overfilling car coolant?

After overfilling the coolant, it may cause excessive pressure in the coolant expansion tank. The introduction of car coolant and precautions when filling are as follows: Introduction: The full name should be antifreeze coolant, meaning coolant with antifreeze function. Coolant consists of three parts: water, antifreeze, and additives. According to different antifreeze components, it can be divided into alcohol type, glycerol type, ethylene glycol type and other types of coolant. Precautions: Do not rashly open the cap when the radiator "boils over". Do not spill water on the engine when adding water. The human body should not come into contact with antifreeze. Different types of antifreeze should not be mixed. Do not operate with insufficient water. After the water inlet shows full, start the engine and run it. When the engine temperature rises to the thermostat opening and the air in the water jacket is discharged, the water level will drop. At this time, the radiator can be filled up again.

What height is suitable for a motorcycle with a seat height of 790mm?

A motorcycle with a seat height of 790mm is suitable for riders over 170cm tall. Notes for riding a scooter: 1. During the entire break-in period, try to choose high-quality mineral oil for lubrication: It is not recommended to use fully synthetic lubricating oil, mainly because the oil change cycle during the break-in period is relatively short, and adding fully synthetic lubricating oil would be a bit wasteful. Ordinary high-quality mineral lubricating oil can meet the basic lubrication needs of a scooter engine. 2. Change the lubricating oil and control the engine speed: During the break-in period of a scooter, apart from changing the lubricating oil, there are not too many things to pay attention to as long as you control the engine speed and maintain a reasonable speed. 3. Operation cannot be separated from the lubrication of oil: The operation of the engine cannot be separated from the lubrication of oil, otherwise it will cause dry friction, and the internal parts of the engine will soon be worn out and fail prematurely.

What color rims go with a red car?

Red cars can be paired with rims of any color, as there are no fixed requirements. Black rims: In the early days, cars mostly used steel rims because steel is prone to rusting—even stainless steel can rust—which can look very unsightly and even affect the rim's strength. Therefore, steel rims require anti-rust paint, typically black, as a base coat. When plastic decorative hubcaps are installed over them, the black base ensures that any gaps don't look too odd. Silver rims: Silver rims are made of aluminum alloy. Aluminum does not rust; instead, it reacts with oxygen in the air to form "aluminum oxide." This substance, commonly called "aluminum rust," tightly adheres to the surface of the aluminum rim, preventing further reaction between external air and the internal aluminum. As a result, aluminum alloy rims do not rust and do not require anti-rust paint.

What is the general exhaust air volume of an exhaust fan?

Generally speaking, the air volume of an exhaust fan with an opening of about 300mm is 200-400 cubic meters per hour. The commonly used product with an opening of 280mm*280mm has an exhaust air volume below 240 cubic meters per hour, which means the volume of air discharged per minute is below 40 cubic meters, generally 4-6 times the room's space volume. Below is a related introduction to the low air volume from car air conditioning vents: 1. Specific reasons: Incorrect air direction selection in car air conditioning, a faulty blower can lead to small air conditioning vents, and a dirty air filter can obstruct the airflow. 2. Solutions for low air volume from car air conditioning vents: Owners can regularly clean the air filter, using a vacuum cleaner to remove dust from the filter or an air compression gun. If the filter is too dirty, it is recommended to replace it. The price of an air filter is not expensive, and the replacement cycle is 10,000 kilometers or half a year.
