The consequences of excessive engine oil temperature include harming the engine, causing localized overheating, and reducing oil viscosity. Below are the specific details: 1. Harm to the engine: When the engine oil temperature is too high, it will affect the normal operation of the engine and cause certain damage. The water temperature mainly indicates the thermal condition of the engine combustion and high-temperature components such as pistons and cylinder walls. 2. Localized overheating: Due to poor heat conduction, localized overheating can occur, especially in parts far from the radiator in the cooling water circulation direction and structurally weak areas, leading to localized deformation, cracks, and burn damage. 3. Low oil viscosity: This results in reduced oil viscosity, oil burn-off, destruction of the oil film in the engine's lubrication points, accelerated wear of components, and in severe cases, can cause bearing seizure or cylinder scoring.

Are Cars Cheaper at Auto Shows?

Buying a car at an auto show may not necessarily be cheaper. Small-scale auto shows primarily aimed at sales often create an atmosphere of scarcity and discounted prices. However, as a consumer, it's essential to stay clear-headed. Before attending the show, visit a 4S store to check out the car and confirm the specific model you want, then understand the actual price floor. Only then negotiate with sales at the auto show. If you can indeed secure a better deal than at the 4S store, proceed with the purchase. Below is an introduction to auto shows: 1. Large-scale auto shows: These are directly participated by manufacturers, mainly aimed at showcasing their brand's vehicles, especially new car launches, and promoting brand culture. The prices are generally no different from buying directly at a 4S store. 2. Small-scale auto shows: These are truly organized for selling cars. Usually hosted by local governments or automotive sales companies to boost sales, they rent a venue for the event. Participants are mostly 4S stores or secondary dealers.

What Causes a Vehicle to Stall When Driving Through Water?

It is strictly prohibited to attempt a second start without any treatment after a car stalls due to water immersion. Although the engine may start normally, water has already entered the engine cylinders through the exhaust pipe backflow. The engine's protection system causes the vehicle to stall. Even if the engine is later repaired, a second start significantly reduces its lifespan and increases the likelihood of malfunctions. Ultimately, there are only two outcomes: replacing the engine or selling the car. The reasons for stalling when driving through water are as follows: Moisture or water ingress causing a short circuit in the high-voltage distribution system, leading to stalling: This is relatively common. The water may appear shallow, and the car seems capable of passing through, but stalling occurs, usually due to splashing water. Water entering the exhaust pipe: The exhaust pipe is positioned low, and if the water level rises above it, the engine stalls due to inability to exhaust. Water entering the air intake: This occurs when water reaches the air filter, causing stalling. This situation is less common and usually happens only when the water level is relatively high.

What does it mean to drive off the designated route in Subject 2?

Driving off the designated route in the Subject 2 test refers to failing to follow the required route specified for the exam. For instance, not adhering to the designated path or sequence during the reverse parking maneuver will result in an immediate deduction of 100 points, leading to automatic test failure. Relevant details are as follows: 1. Category C: The Subject 2 test for small vehicles (C1/C2) includes five mandatory items: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving. 2. Large Vehicle License: The test for large vehicles (A1/A2/A3/B1/B2) covers pile test, stopping and starting on a slope, parallel parking, single-plank bridge crossing, curve driving, right-angle turns, passing through a limited-width gate, navigating continuous obstacles, driving on undulating roads, narrow-road U-turns, as well as simulated scenarios like highways, continuous sharp mountain curves, tunnels, rain/fog conditions, slippery roads, and emergency handling.

What is the Road Traffic Sign System?

The Road Traffic Sign Recognition System alerts drivers to road sign information, such as current speed limits and no-passing zones. If the vehicle has just passed a sign, the information will be displayed on the multi-information display and heads-up display. System Operation: While driving, a camera located behind the rearview mirror captures traffic signs, and the system will display the recognized signs designated for the vehicle. The sign icons will be displayed for a certain period until the vehicle reaches a predetermined time and distance. Relevant information about traffic signs is as follows: 1. Introduction: Signs are symbols of civilization, referring to directions in public places, including commercial areas, non-profit public institutions, urban transportation, communities, etc. 2. Introduction to Urban Sign Systems: The urban sign system is part of the city's public welfare configuration. It refers to visual image systems set up in the city that clearly indicate content, location, direction, principles, and other functions in the form of text, graphics, and symbols.

Is there a paper transcript for Subject One?

Subject One is a computer-based test, and the results are directly displayed in the personal information section of the traffic management network. A paper transcript is also available, typically kept in the archives of the driving school where you registered, and is not issued to individuals. Relevant details are as follows: 1. Content: Subject One refers to the theoretical driving test conducted at the vehicle management office, a mandatory licensing exam for driver's license applicants. The test covers fundamental driving theory, road safety laws and regulations, traffic signals, traffic rules, and local regulations. The scheduling of the theoretical driving test is determined by the local vehicle management office. 2. Driver's License Exam: Subject One is part of the teaching and examination outline for motor vehicle driver training. The examination section of this outline is divided into three subjects, organized by the traffic management department of the public security authority. The exams proceed in the order of Subject One, Subject Two, and Subject Three. Passing the previous subject allows you to proceed to the next; failing the previous subject requires retaking that subject.
