What does A3B4 mean for engine oil?

A3B4 refers to the grade of engine oil. Here are the detailed explanations: 1. 'A' indicates engine oil for gasoline engines; 'B' indicates engine oil for diesel engines; the number following the letter represents the grade of the oil, with a higher number indicating a higher grade; A3B4 engine oil means it can be used in both gasoline and diesel engines. 2. Engine oil is very important for the engine, often referred to as the 'blood' of the engine. Without engine oil, the engine cannot operate normally. 3. Besides lubrication, engine oil also plays roles in cleaning, sealing, buffering, rust prevention, and heat dissipation. 4. During engine operation, the oil forms a thin film inside the engine, preventing direct contact and friction between components, thus protecting the engine. 5. Without engine oil, components would directly contact and create friction during operation, generating excessive heat instantly, which can severely damage the engine. 6. Overheating in the engine can lead to knocking, which reduces engine power and increases fuel consumption.

What is the Purpose of a Central Differential?

In multi-axle drive vehicles, the drive axles are connected by drive shafts. To allow each drive axle to potentially have different input angular velocities and eliminate the sliding phenomenon of the wheels on each axle, a central differential, also known as an inter-axle differential, can be installed between the drive axles. Below is an introduction to this mechanism: 1. When turning, the distances covered by the inner and outer wheels along their respective curves in the same time period are obviously different, with the outer wheels covering a greater distance than the inner wheels. If both wheels are fixed to the same rigid rotating shaft and rotate at the same angular speed, the outer wheel will inevitably experience a combination of rolling and sliding, while the inner wheel will experience a combination of rolling and skidding. 2. When driving straight on uneven road surfaces, the actual distances covered by the left and right wheels are also unequal, necessitating adjustment by the central differential.

Can modified xenon bulbs pass the annual inspection?

Self-modified xenon bulbs can pass the annual inspection if they are equipped with lenses and have a color temperature below 6000 lumens. Those without lenses will not pass the inspection. Some relevant information about modifying xenon bulbs is as follows: 1. When choosing xenon bulbs for modification, the first thing to consider is the tube. Select one with a smooth surface, straight alignment, and uniform thickness. 2. It is recommended to follow relevant regulations when modifying xenon lights. Do not install bare xenon bulbs; add lenses if necessary. 3. Good xenon bulb brands from abroad include Philips and Osram, but due to cost factors, these international brands generally pay little attention to the domestic modification market.

How often should Kia K3 tires be replaced?

Kia K3 tires typically need to be replaced every 50,000-60,000 kilometers. The lifespan of tires is influenced by various external factors such as climate, road conditions, driving habits, and maintenance, so specific situations should be analyzed individually. Below are the circumstances under which tires need to be replaced: 1. Tires must be discontinued when worn down to the wear limit indicator, meaning the tread depth is below 1.6 millimeters. 2. Tires with deformed treads or damaged bead areas, those damaged by driving under-inflated leading to sidewall compression, or those corroded by chemicals should not be used further. 3. Bulging tires or severely aged tires should be replaced promptly.

Where to Look at Tire Tread Patterns?

Tire tread pattern models can be found on the side of the tire. Generally speaking, tire treads refer to the grooves composed of various longitudinal, transverse, and diagonal patterns on the tire surface. Here is an introduction to tire tread patterns: 1. Longitudinal tread patterns, due to their continuous longitudinal characteristics, primarily serve the function of draining water in rainy conditions and also help with tire heat dissipation, but they lack sufficient grip. 2. Transverse tread patterns, on the other hand, provide greater grip, thereby compensating for the inherent shortcomings of longitudinal tread patterns. 3. The longitudinal tread patterns on tires mainly serve to quickly drain water, but they result in insufficient grip; whereas the transverse tread patterns on tires offer higher grip but have poor water drainage and directional stability. Therefore, hybrid tread patterns were developed, combining the quick-draining longitudinal treads in the middle with the grip-providing transverse treads on the shoulders, achieving an optimal balance.

How Often Should a New Car Be Serviced Normally?

Different vehicles have varying service intervals. Generally, it is recommended to service every 5,000 kilometers or every six months. The first service typically includes an oil change and replacing the three filters. Some manufacturers may recommend an initial service at 2,500 kilometers or three months. Here is an introduction to car maintenance: 1. The period before the first service is the vehicle's break-in period. During this time, as the engine gradually breaks in, contaminants such as dust, metal wear, and carbon deposits will continuously mix into the engine oil. Since the oil during the break-in period contains many impurities, driving at high speeds can lead to abnormal engine wear. Therefore, replacing the oil and oil filter during the first service is crucial. If the debris and particles generated by the engine are not promptly removed, they may cause abnormal damage to the internal components of the cylinders. 2. During the first service of a new car, the nuts and bolts in various parts of the vehicle should be inspected. Due to the break-in period, some screws may not be tightened to their full specifications. During the first service, all screws will be tightened to the specified torque. The car will also be lifted to inspect the undercarriage for any scratches, impacts, corrosion, or oil leaks. Additionally, the tires will be checked to ensure even wear. If one tire shows significantly more wear than the others, it may indicate misalignment. Tire pressure will also be checked and adjusted as needed.
