Can the Driving Test Be Transferred Back After Being Transferred Out?

It is possible to transfer to another location for the Subject 3 test. Below are the relevant details about the Subject 3 driving test: 1. Introduction: Subject 3 includes the road driving skills test and the safety and civilized driving knowledge test. It is part of the motor vehicle driver's license assessment and is the abbreviation for the road driving skills and safety and civilized driving knowledge test subjects in the motor vehicle driver's examination. The content of the road driving skills test varies for different types of vehicles. 2. Specific Content of Subject 3: The road driving skills test generally includes: preparation before driving, simulated light test, starting, driving straight, gear shifting operations, changing lanes, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and nighttime driving. The safety and civilized driving knowledge test generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and knowledge of handling after traffic accidents.

How to Read the Vehicle Temperature Gauge?

Automobile water temperature gauges are marked with the letters "C" and "H", or distinguished by white and red zones. "C" stands for the first letter of the English word "cool", meaning cold. "H" stands for the first letter of the English word "hot", meaning heat. Relevant information about the automobile water temperature gauge is as follows: 1. Introduction: The water temperature refers to the temperature of the coolant. After the engine warms up, it generally displays between 70-90 degrees as normal. When the water in the cooling tank is low, the water temperature will rise, and it is necessary to add water at this time. If the temperature gauge approaches the "H" or the red danger zone, and in severe cases, the water temperature warning light comes on, it indicates that the engine coolant temperature is too high. 2. How the Water Temperature Gauge Works: The sensor of the water temperature gauge is a thermistor-type sensor. It is fixed with threads on the engine cooling water passage. The thermistor determines the magnitude of the current flowing through the coil winding of the water temperature gauge.

Is the BYD e2 Equipped with Blade Battery?

BYD e2 is equipped with blade battery. Here is the relevant introduction about BYD e2: 1. Introduction of BYD e2: BYD e2 made its official debut at the 2019 Shanghai Auto Show. As a "new intelligent pure electric crossover" of the e-series, it is built based on BYD's all-new e-platform. The e2 adopts a fashionable design concept inspired by the starry sky, equipped with core three-electric technology, trendy design, and intelligent technological configurations. 2. Advantages of BYD e2: BYD e2 is a compact electric vehicle under BYD Auto. The latest model is equipped with BYD's cutting-edge technology—the blade battery. Three variants come with blade lithium iron phosphate batteries, with a battery capacity of 43.2kWh. The blade battery offers similar range and performance to ternary lithium batteries but is more stable, safer, and has a longer lifespan. Thanks to its unique shape and structural layout, the blade battery significantly improves space utilization and energy density, making its range and overall performance no less than that of ternary lithium batteries.

What is the detection method for the crankshaft position sensor?

Detection method for the crankshaft position sensor is as follows: Turn on the ignition switch, measure the voltage of the two signal lines to ground should be 1.4V, which is the preset voltage on the signal line by the engine control unit. When starting the starter, measure the signal voltage of the crankshaft position sensor should be close to 1.6V. If there is an open or short circuit inside the sensor, signal lines, or engine control unit, it will cause the computer to be unable to receive the crankshaft position signal, and the engine will fail to start. Extension: If the crankshaft position sensor is damaged, the rotation angle of the crankshaft cannot be confirmed, and the engine computer cannot receive the signal from the crankshaft position sensor. To protect the engine, it will not ignite or inject fuel. The symptoms shown by the car are no high voltage, no fuel injection, and failure to start. The most obvious phenomenon is that the engine fault light on the dashboard lights up.

What Causes Engine Shaking When Spark Plugs Get Wet?

Generally, spark plug issues can lead to poor engine performance, resulting in abnormal phenomena such as difficulty starting, unstable idle, poor acceleration, backfiring during sudden acceleration, excessive exhaust emissions, and increased fuel consumption. A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. Spark plugs are installed on the side or top of the engine. In earlier designs, spark plugs were connected to the distributor via ignition cables. However, over the past decade or so, engines in passenger cars have largely transitioned to direct connection between ignition coils and spark plugs. Under high voltage, the air between the center electrode and side electrode of a spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. This creates a discharge channel between the gap, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body known as a "spark." Along with the heat and expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2,000 to 3,000°C, which is sufficient to ignite the air-fuel mixture in the engine's combustion chamber.

What do C and H on the dashboard represent?

The CH on the dashboard represents the water temperature gauge. The water temperature ranges from C to H. C stands for 60 degrees Celsius. Once the needle of the water temperature gauge reaches C, it indicates that the water temperature has reached 60 degrees. The red H mark represents a temperature of 110 degrees Celsius. The span from 60 to 110 degrees Celsius allows for an estimation of the temperature indicated by the water temperature gauge. Introduction to the water temperature gauge: Automobile water temperature gauges generally use a scale from 60 degrees Celsius to 120 degrees Celsius or are labeled with Cold (C) to Hot (H). The water temperature indicator light is used to show the temperature of the coolant inside the engine. Some indicators use colors to display different statuses: blue indicates the water temperature is too low, red indicates the water temperature is too high, and no light indicates normal operation. When a car engine is running, the combustion of gasoline generates significant heat, with some being expelled through the exhaust pipe and some transferring to the engine block. If the engine block temperature becomes too high, it can cause thermal expansion of components and lead to damage. Therefore, water is used for circulating cooling. Hazards of excessively high or low water temperature: Hazards of low water temperature: It can cause incomplete combustion of the air-fuel mixture, reduce power output, increase fuel consumption, lead to poor lubrication, and result in excessive emissions. Hazards of high water temperature: Normally, when the water temperature is within the normal range, the needle will point to the middle position of the water temperature gauge (this may vary between different car models; it is recommended to check the warranty manual). However, there is usually a red zone on the right side of the water temperature gauge indicating the high-temperature range. When the needle approaches this zone, caution is required as it indicates the water temperature is too high. If no action is taken and driving continues, it can easily lead to the radiator boiling over.
