What are the consequences of missing the Subject 4 exam?

Missing the Subject 4 exam will be treated as a failure. You can reschedule a make-up exam. Below is more information about the subject exams: 1. Immediate failure: Each subject exam can be taken once, and if failed, an immediate make-up exam is allowed. If you don't take the make-up exam or fail it again, the current exam session ends, and the applicant must reschedule the exam, which can only be done after 10 days. 2. Exam rescheduling eligibility: Within the validity period of the driving skills test permit, the number of rescheduled exams for Subject 2 and Subject 3 road driving skills tests cannot exceed five times. If you fail the fifth rescheduled exam, the results of other subjects you have passed will be invalidated. Failing the Subject 4 safety and civilized driving knowledge test does not affect the validity of the passed road driving skills exam results.

Is an Aluminum or Plastic Thermostat Housing More Suitable for Cars?

Both aluminum and plastic thermostat housings are suitable for cars. The thermostat is a valve that controls the flow path of the coolant. It automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity and ensure the engine operates within the appropriate temperature range. Methods to determine if the thermostat is damaged include: 1. After starting the engine, open the filler cap of the coolant reservoir and observe if there is any water flow inside. If not, it indicates the thermostat is damaged or debris is stuck between the main valve's opening and closing mechanism. 2. After starting the engine, feel the upper and lower radiator hoses. If they are at the same temperature, it means the thermostat is damaged.

What to Do When the Motorcycle Key Won't Turn

There are several possible reasons why a motorcycle key won't turn: 1. Check if the key is original: Using a non-original key may prevent it from turning. 2. Inspect the key for damage or deformation: If the key has been subjected to external force causing it to bend or break, it won't turn when inserted. 3. Visit a repair shop: If the above issues aren't present, have a professional check the lock cylinder's condition. Emergency methods for lost keys: 1. DC ignition system: Open the handlebar cover and look below the ignition switch to find a black wire and a red wire. Connect these two wires with a large pin to start the vehicle. 2. AC ignition system: Open the handlebar cover and look below the ignition switch to locate a black-and-white wire. Temporarily cutting this wire will allow the vehicle to start.

Do you need to wait for the red light in the left-turn lane?

You need to wait for the red light when turning left. When the red light is on, vehicles are prohibited from passing, and you cannot make a U-turn or left turn directly. Regulatory basis: The "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" has corresponding provisions: Article 38 states that motor vehicle signal lights and non-motor vehicle signal lights indicate: When the green light is on, vehicles are allowed to pass, but turning vehicles must not hinder the passage of released straight-going vehicles and pedestrians. When the yellow light is on: Vehicles that have already crossed the stop line may continue to pass. When the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle signal lights or pedestrian crossing signal lights, non-motor vehicles and pedestrians shall follow the instructions of the motor vehicle signal lights.

How much is the starting current of an engine starter?

When a gasoline engine starts, the battery output current can reach 200 to 600 amps, while for a diesel engine, it can reach up to 1000 amps. Introduction to starting current: The starting current (CCA) index refers to the minimum current obtainable under specific conditions at -17.8°C and -28.9°C. This index links the starting capability of the battery with important variables such as engine displacement, compression ratio, temperature, starting time, the technical state of the engine and electrical system, and the minimum operating voltage for starting and ignition. Starting current vs. operating current: Generally, the starting current is 20 times the operating current. This occurs when the battery is weak or not fully charged, or possibly when the under-voltage indicator is damaged. It is recommended to test the battery voltage after 25 kilometers. For a 48V battery, a reading around 50V is considered normal.

What kind of oil should be used in a continuously variable transmission?

Continuously variable transmissions require gear oil, and it is recommended to use gear oil with a viscosity below 150, preferably on the lower side. The specific choice depends on the model of the machine and the working environment. Introduction to Continuously Variable Transmission: A continuously variable transmission (CVT) is a type of automatic transmission in vehicles that can continuously obtain any transmission ratio within its range. It allows for optimal matching between the transmission system and the engine's operating conditions. Common types of CVTs include hydro-mechanical continuously variable transmissions, metal belt-type continuously variable transmissions (VDT-CVT), and variable-angle continuously variable transmissions. Difference between CVT and Automatic Transmission: The main difference between a CVT and a conventional automatic transmission is that the CVT eliminates the complex and bulky gear combination for transmission, instead using only two sets of pulleys for variable transmission. By changing the contact radius of the drive belt between the driving and driven pulleys, the CVT achieves variable transmission, showcasing a very ingenious design concept.
