Does the Examiner Stepping on the Brake Mean Failing the Test?

Generally speaking, if the examiner steps on the brake, it won't directly result in the examinee failing the test. However, it may cause the vehicle to stall during the subsequent examination. If the car suddenly stalls while passing through an intersection or a crosswalk, it will lead to a failure. Below is more information about the driver's license examination: 1. Subject 1: Examination on road traffic safety laws, regulations, and related knowledge. The structure of the exam question bank and the basic question types are formulated by the Ministry of Public Security, while provincial traffic management departments under the public security authorities establish the question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. 2. Subject 2: Examination on field driving skills, including test items such as reversing into a parking space, stopping and starting on a slope, making a right-angle turn, driving along a curve, and parallel parking. 3.

What is Sunwide Tire?

It is a Sunwide tire, which is a semi-steel passenger car tire. It is primarily produced and processed by Shandong Linyi Fomax Tire Co., Ltd., specializing in the design, development, production, and processing of semi-steel radial tires for various series such as passenger cars, light trucks, and off-road vehicles. Tires are ring-shaped elastic rubber products assembled on various vehicles or machinery. They are usually mounted on metal rims to support the vehicle body, maintain contact with the road surface, and ensure driving performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high/low temperatures during operation, so they must have high load-bearing, traction, and cushioning performance. Additionally, they require high wear resistance and bending flexibility, as well as low rolling resistance and heat generation. Its product lineup mainly includes car tires, SUV tires, winter tires, commercial tires, taxi tires, light truck tires, run-flat tires, and high-performance tires, meeting most tire needs. Sunwide tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high/low temperatures during operation. Therefore, they must have high load-bearing, traction, and cushioning performance, along with high wear resistance and bending flexibility, as well as low rolling resistance and heat generation. They directly contact the road surface and work with the vehicle suspension to absorb shocks during driving, ensuring good ride comfort and smoothness. They also ensure strong adhesion between the wheels and the road, improving traction, braking, and off-road performance while bearing the vehicle's weight. Sunwide Tire Maintenance Methods: Enhance awareness of tire safety and inspect tires regularly. Regularly adjust wheel balance, as unbalanced wheels can cause high-frequency vibrations at high speeds, leading to uneven tire wear. Rotate tires periodically. To ensure even wear on all tires of the same vehicle, rotate them every 5,000 kilometers. In daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear, the tread grooves gradually become shallow. If the tread is worn out, it loses its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks can also pose a risk of blowouts at high speeds. Additionally, remove stones from the grooves immediately. Park on flat ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may degrade rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool tires. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, stop to let the tires cool naturally. Never deflate or splash water to cool them, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear caused by dragging between the tires and the ground.

What does a white background with red text in traffic signs mean?

According to the relevant regulations of "Road Traffic Signs and Markings Part 2: Road Traffic Signs" (GB5768.2-2009), signs with a white background and red text are prohibition signs. These signs indicate the prohibition or restriction of vehicle and pedestrian traffic behaviors. There are a total of 50 prohibition signs. There are various types of traffic signs, which can be categorized in different ways: main signs and auxiliary signs; movable signs and fixed signs; illuminated signs, luminous signs, and reflective signs; and variable message signs that reflect changes in the driving environment. Road traffic signs are divided into two main categories: main signs and auxiliary signs. Main signs are further divided into six types: warning signs, prohibition signs, directive signs, guide signs, tourist area signs, and road construction safety signs. Warning signs serve to alert and there are 49 types in total. Warning signs alert drivers and pedestrians to dangerous locations. They feature a yellow background with black borders and black patterns, shaped as an equilateral triangle with the apex pointing upward. Prohibition signs have a white background with red circles, red bars, and black patterns, with the pattern overlaid on the bar. Among these, signs indicating the end of no-overtaking or speed limit restrictions have a white background with black circles, black bars, and black patterns, with the pattern overlaid on the bar. These signs are circular in shape, while yield signs are shaped as an equilateral triangle with the apex pointing downward. Directive signs have a blue background with white patterns. Their shapes include circles, rectangles, and squares. Guide signs, except for milestones, hundred-meter posts, and highway boundary markers, generally have a blue background with white patterns. Except for location identification signs, they are mostly rectangular or square in shape. Tourist area signs have a brown background with white characters. Road construction safety signs come in many types and color schemes, including blue background with white text, yellow background with black patterns, red and white stripes, and yellow and black stripes. Their shapes include rectangles, columns, and cones. The main functions of road traffic signs are: Providing road information, serving as the language of the road. Directing and controlling traffic to ensure road safety. Guiding and orienting to improve driving efficiency. Serving as a basis for law enforcement by traffic management authorities. Important Notes: Novice drivers, due to their lack of personal experience with traffic signs, are most likely to violate traffic sign regulations. Additionally, due to misunderstanding or failing to notice traffic signs in time, they may easily take wrong routes or unnecessary detours. These situations are often unavoidable. To better observe traffic signs, novice drivers should pay attention to signs placed on the roadside or overhead while driving, maintaining a high and far-reaching field of vision. They should understand the meaning of traffic signs before proceeding. Moreover, when approaching intersections, there are often directional markings on the road. Novice drivers, often fixated on the road ahead, may overlook these directional traffic signs, leading to violations or unnecessary detours. Therefore, when approaching an intersection, it is important to slow down in advance, carefully observe the traffic signs on the road and at the intersection ahead, and correctly choose the driving route.

What engine does Changan Oushang use?

Changan Oushang's engine is independently produced by Changan Company, with its production base located in Chongqing, making it a domestically manufactured engine. In the Changan Oushang series, the Oushang X7 is equipped with the JL476ZQCF engine model, featuring a maximum power of 131kW, maximum horsepower of 178, and maximum torque of 265Nm. The 1.5T version of the Oushang X5 uses the Blue Whale NE1.5T engine model, delivering a maximum power of 132KW, maximum torque of 300Nm, and maximum horsepower of 180. For daily maintenance of Changan Oushang's engine, the following methods can be applied: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine issues. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. 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 becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, 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 particles from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

How Many Kilograms is 20 Liters of Gasoline?

The weight of 20 liters of gasoline ranges between 28 to 31.2 kilograms. The density of gasoline varies slightly depending on the type of gasoline and seasonal climate, with gasoline density ranging from 0.70g/cm³ to 0.78g/cm³. If the gasoline density is taken as 0.70g/cm³, then 20*0.70=14=28 kilograms. If the gasoline density is taken as 0.78g/cm³, then 20*0.78=15.6 kilograms=31.2 kilograms. The weight of gasoline itself also depends on temperature. Due to different seasonal climates, the density of gasoline changes slightly. When the temperature rises, the volume of each liter of gasoline increases, and the density decreases. When the temperature drops, the density of each liter of gasoline increases, and the volume decreases. This means that the same liter of gasoline has different weights and densities in different temperature seasons. Therefore, the mass of 1 liter of 92-octane gasoline should be m=0.725g/ml*1000ml=0.725kg=1.45 kilograms; the density of 95-octane gasoline is 0.737g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.737g/ml*1000ml=0.737kg=1.47 kilograms; the density of 90-octane gasoline is 0.72g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.72g/ml*1000ml=0.72kg=1.44 kilograms; the density of 93-octane gasoline is 0.725g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.725g/ml*1000ml=0.725kg=1.45 kilograms; the density of 97-octane gasoline is 0.737g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.737g/ml*1000ml=0.737kg=1.47 kilograms. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Its main components are C5~C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is divided into common grades such as 92, 95, and 98 based on octane levels. The calorific value of gasoline is approximately 44000 kJ/kg. The ignition point of gasoline is between 415-530°C. The surface of gasoline is a transparent liquid and is flammable. Gasoline usually contains mechanical impurities and water. Mechanical impurities can cause serious consequences such as clogged fuel lines and increased wear. Important characteristics of gasoline include volatility, stability, anti-knock properties, corrosiveness, and cleanliness. When adding gasoline, car owners can check the appropriate gasoline grade in the car manual or on the fuel tank cap, which is usually marked. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, those between 10.0-11.5 should use 95-octane gasoline, and those with higher compression ratios should use 98-octane gasoline. However, with the use of some new technologies, the gasoline grade cannot be determined solely based on the compression ratio. High compression ratios can also be adjusted to use lower-grade gasoline because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role.
