Is the Parking and Card Retrieval Test Part of Subject 2 or Subject 3?

Parking and card retrieval is part of Subject 2. Below is a detailed introduction to the precautions for parking and card retrieval: 1. Avoid crossing the line: When entering the parking and card retrieval section, in addition to looking at the front of the car and aligning the body, you should also pay attention to the rearview mirror to prevent the rear wheels from crossing the line. 2. Find the correct position: During the test, control the speed, find the correct parking position, and stop in time. Otherwise, missing the correct position will make it impossible to retrieve (or swipe) the card, or reversing to adjust the position will result in failing the test. 3. Control the distance: Similar to parallel parking, the parking position for card retrieval must be well-controlled—you cannot cross the line, but you also cannot be too far away. Exceeding 500mm will result in a deduction of 100 points.

What are the advantages and disadvantages of 360-degree car mats?

The advantages of 360-degree car mats are water absorption, dust absorption, stain removal, sound insulation, and protection of the main unit, while the disadvantage is that universal mats are prone to slipping. It is recommended that car owners choose custom-fit car mats, which are safer and more aesthetically pleasing to use, help maintain effective interior space, and are less likely to slip. Below is an introduction to windshield washer fluid: 1. Cleaning performance: Windshield washer fluid typically has functions such as wetting, penetrating, and solubilizing, thereby serving the purpose of cleaning and removing stains. 2. Antifreeze performance: The presence of alcohol and ethylene glycol can significantly lower the freezing point of the liquid, thus serving an antifreeze purpose and quickly dissolving frost.

Is it necessary to install car floor mats?

It is highly necessary to install car floor mats for private vehicles. Below is an analysis of why floor mats should be installed based on their functions: 1. Floor mats integrate five major functions: water absorption, dust absorption, stain removal, sound insulation, and protection of the main carpet, making them an eco-friendly automotive interior component. 2. Car floor mats serve as interior decorations that maintain cleanliness both inside and outside the vehicle, adding aesthetic and comfortable touches. 3. The water absorption, dust absorption, and stain removal capabilities of car floor mats can effectively prevent residual moisture and dirt from shoe soles from causing slippage between the clutch, brake, and accelerator, thereby avoiding potential safety hazards and reducing the likelihood of interior contamination and damage. After all, cleaning floor mats is more convenient and economical than cleaning the interior.

Which country's engine is used in the BJ80?

BJ80's engine is provided by Liuzhou Wuling Liuji Power Co., Ltd., which is a domestic engine. The 2.3T version of the BJ80 engine has the model number B231R, with a maximum power of 170kw and a maximum torque of 280 Nm. The 3.0T version has the model number 6G30TQY, with a maximum power of 206kw and a maximum torque of 420 Nm. The following methods can be used for daily maintenance of the BJ80 engine: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance will deteriorate, causing various problems for the engine. To avoid faults, change the oil regularly according to usage conditions and keep the oil level moderate. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry dirt back to the lubrication parts, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine works properly but also extends the overall lifespan of the radiator and engine.

What Are the Causes of Car Shock Absorber Oil Leakage?

Car shock absorber oil leakage is mainly caused by the following reasons: 1. Poor internal cleanliness of the shock absorber, with welding slag, iron filings, and other debris causing oil seal wear. 2. Harsh working conditions of the shock absorber, allowing external debris like mud and sand to enter the oil seal, leading to wear and oil leakage. 3. Aging of the sealing lip of the shock absorber oil seal, resulting in loss of sealing function. 4. Failure to properly cover the shock absorber during chassis armor spraying, causing the armor to adhere to the shock absorber piston rod and leading to oil seal wear and leakage. 5. The control rod for piston movement needs to extend from one end of the metal tube, and this area requires strict sealing. General oil leakage is directly related to inadequate sealing in this part.

What is the function of a car chassis?

The function of a car chassis is to support and install the car engine and its various components and assemblies, forming the overall shape of the car. It receives the power from the engine, enabling the car to move and ensuring normal operation. The car chassis is another important component besides the engine. The chassis consists of the transmission system, running gear, steering system, and braking system. The transmission system is generally composed of the clutch, gearbox, universal transmission device, main reducer, differential, and half-shaft. The function of the transmission system is to transfer the power generated by the car engine to the driving wheels. The transmission system has functions such as deceleration, speed change, reversing, power interruption, inter-wheel differential, and inter-axle differential. Working in coordination with the engine, it ensures the normal operation of the car under various working conditions, providing good power performance and fuel economy. The running gear consists of the car frame, axle, wheels, and suspension. The function of the running gear is to receive the power from the transmission system and generate traction through the interaction between the driving wheels and the road surface, enabling the car to operate normally. It bears the total weight of the car and the reaction force from the ground, mitigates the impact of uneven road surfaces on the car body, dampens vibrations during driving, and maintains smooth operation.
