Is There Intentional Screening in Subject Two?

Subject Two does not involve intentional screening. As long as you have truly mastered traffic regulations knowledge and driving skills, you will definitely pass the Subject Two test smoothly. Content of Subject Two Assessment: Subject Two, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the field driving skills test. For the C1 license, the test items include five mandatory components: reverse parking, parallel parking, hill start and stop, right-angle turn, and curve driving (commonly known as the S-curve). Some regions also include a sixth item: highway toll card collection. For the C2 license, the test items include four mandatory components: reverse parking, parallel parking, right-angle turn, and curve driving (commonly known as the S-curve). Precautions for the Subject Two Test: Pay attention to controlling the speed during reverse parking. You must start within 30 seconds; maintain a reasonable 30cm side margin and reference points during parallel parking; adjust the vehicle body slowly during curve driving, ensuring the wheels do not cross the lines; and find the right moment to turn the steering wheel during right-angle turns.

What does L2-level intelligent driving mean?

L2-level autonomous driving, which means partial automation of the vehicle, simply put, requires the system and the driver to control the car together. The advanced driver-assistance system (ADAS) must at least include longitudinal and lateral automatic control functions, allowing the vehicle to operate automatically under certain specific conditions. Here is some relevant information: 1. L2-level autonomous driving falls under partial automation, where basic operations are performed by the vehicle, while the driver is responsible for monitoring the surroundings and taking over the vehicle when necessary. Key features include ACC (Adaptive Cruise Control), automatic follow-up driving, automatic parking, etc. For example, when using automatic parking, if an unexpected person enters the surrounding area while the vehicle is automatically parking, the driver must immediately intervene. 2. When using ACC, if the vehicle ahead suddenly slows down or brakes unexpectedly, manual intervention is required for an immediate response. Therefore, most vehicles equipped with ACC have certain speed range limitations. Vehicles equipped with full-speed adaptive cruise control (with higher autonomous capabilities) can also be referred to as L2.5-level autonomous driving.

Is it okay to change the oil for a new motorcycle at 500 kilometers?

It is perfectly fine to change the oil for a new motorcycle after running 500 kilometers. Many motorcycles require the first oil change at 300-500 kilometers, while some models recommend the first oil change at 1,000 kilometers. The exact mileage for an oil change is not strictly fixed—being slightly earlier or later is generally not a problem, as long as you remember to change it promptly. Engine Oil: Engine oil, also known as engine lubricant (English name: Engine oil), has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions for the engine, including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a vehicle. Composition: Engine oil consists of two main components: base oil and additives. The base oil is the primary ingredient of lubricants, determining their fundamental properties. Additives, on the other hand, compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. They are a crucial part of lubricants.

What causes the Kia K5 to make a rattling noise when cold but not when warm?

The reason why the Kia K5 makes a rattling noise when cold but not when warm is: 1. During a cold engine start, the oil pump cannot immediately establish oil pressure, and oil films cannot form between components, leading to insufficient lubrication during cold starts. Whether it's hydraulic lifters or mechanical rocker arms, there will be some valve clearance, resulting in the rattling noise; 2. After the engine runs for a while, oil pressure is established, oil films form, and the engine oil temperature rises. Once the engine operates normally, the rattling noise disappears. The Kia K5 is a mid-size sedan under Dongfeng Yueda Kia. Taking the 2020 Kia K5 as an example, its body dimensions are 4980mm in length, 1860mm in width, and 1445mm in height, with a wheelbase of 2900mm. The body structure is a 4-door, 5-seater sedan. In terms of power, the 2020 Kia K5 is equipped with 1.5T and 2.0T turbocharged engines, paired with a 7-speed dual-clutch transmission and an 8-speed automatic transmission.

Why Does a Car Feel Floaty at High Speeds?

There are several reasons why a car may feel floaty at high speeds: 1. The lower the chassis, the more floaty the car feels at high speeds, while a higher chassis provides more stability: Vehicles with higher chassis have stiffer suspension support, offering better stability, and the steering wheel feels heavier, reducing the sensation of floatiness at high speeds. 2. Aerodynamic design factors: This includes how streamlined the car's design is, the strength of air resistance, and the level of friction between the tires and the road. 3. The position of the car's center of gravity: The height of the center of gravity from the ground acts as a lever arm. According to the principle of leverage, if the force applied is equal, a longer lever arm results in a greater torque. When the centrifugal torque exceeds the gravitational torque, the car may roll over. Even if the centrifugal force isn't strong enough to cause a rollover, it can still create unequal force distribution on the left and right tires. One side may experience increased contact area, while the other side's contact area decreases, significantly affecting the car's handling stability and potentially leading to loss of control.

What engine does the Familia use?

Familia uses two types of engines in total, one is a 1.6-liter turbocharged engine, and the other is a 1.5-liter naturally aspirated engine. The maximum power of the 1.6-liter naturally aspirated engine is 92kw, matched with either a 6-speed manual transmission or a 6AT transmission; the maximum power of the 1.5-liter turbocharged engine is 115kw, matched with a 6AT transmission. The Familia is a compact sedan under Haima. Taking the Familia 2017 1.6L Automatic Comfort model as an example: its length, width, and height are 4698mm, 1806mm, and 1477mm respectively, with a wheelbase of 2685mm, and the body structure is a 4-door 5-seater sedan. In terms of the chassis system, the Familia 2017 1.6L Automatic Comfort model adopts a front MacPherson independent suspension and a rear multi-link independent suspension, with a front-engine, front-wheel-drive layout.
