What Causes Thick White Smoke from the Exhaust Pipe?

Thick white smoke from the exhaust pipe is caused by the engine burning coolant. Here are the specific reasons: 1. Reasons for the engine burning coolant: Cracks in the cylinder block; cracks in the cylinder head gasket. 2. Inspect the cylinder block and cylinder head gasket separately: If the cylinder block is cracked, it should be replaced; if the cylinder head gasket is cracked, it should be replaced. Below is some information about coolant: 1. Function: Water-cooled engines rely on coolant continuously circulating within the engine to dissipate heat, as the coolant carries away excess heat. 2. Note: Coolant needs to be replaced regularly. If not changed for a long time, it can lead to an increase in the freezing point and a decrease in the boiling point of the coolant.

What is the Principle of Tire Pressure Sensors?

Tire pressure sensors primarily operate based on the following two principles: 1. Direct Tire Pressure Monitoring: This method uses pressure sensors installed in each tire to directly measure the air pressure. A wireless transmitter then sends the pressure data from inside the tire to a central receiver module, which displays the pressure readings for each tire. 2. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds among the tires, the system monitors the tire pressure. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tires to monitor air pressure.

What are the symptoms of a faulty car air conditioning compressor?

The symptoms of a faulty compressor are as follows: 1. Compressor seizure - The compressor fails to rotate. The cause is poor lubrication or lack of lubrication. For instance, if the refrigeration oil leaks due to refrigerant leakage, or if the oil overflow pipe of the evaporator, the oil overflow valve of the POA valve, or the oil hole of the oil-gas separator (accumulator) in the CCOT system is blocked, the compressor may seize due to insufficient refrigeration oil. 2. Compressor leakage - There are two scenarios: oil leakage and gas leakage. In minor cases, only refrigerant leaks; in severe cases, both refrigerant and refrigeration oil leak. There is also slight leakage at the shaft seal. If the annual leakage is less than 14.2g, it does not affect the refrigeration system's performance and is considered normal. If the leakage exceeds 14.2g, maintenance is required, including replacing the seals. If the compressor's cylinder block cracks and causes leakage, the compressor should be replaced. 3. Poor compressor operation - A manifold pressure gauge can be used to measure the compressor's suction and discharge pressures. If both pressures are the same and the compressor feels abnormally hot when touched, the cause may be cylinder gasket blow-by. High-pressure gas from the discharge valve leaks back into the suction chamber through gaps in the cylinder gasket, gets compressed again, and produces even hotter vapor. This cycle can carbonize the refrigeration oil, rendering the compressor useless. If the intake or discharge valve springs are damaged or weakened, the compressor may fail to compress the refrigerant or compress poorly. In this case, the suction and discharge pressures may be the same or similar, but the compressor will not overheat.

How to Use the Key to Raise and Lower the Windows on the Envision?

Specific usage method: Short press: The window will automatically lower all the way; Short pull: The window will automatically rise all the way; Long press: Release during the window's descent to stop it; Long pull: Release during the window's ascent to stop it. Below is relevant information: 1. One-touch window operation: One-touch window operation refers to a system where the car window glass can be controlled to raise or lower into position with a single button press. Cars equipped with one-touch window operation have two-stage window control switches. The first button position functions like a regular power window. The second position allows the window to automatically fully open or close with a single press and release. 2. Precautions: When the window encounters an obstacle (such as a hand or head) during ascent, it can automatically reverse to the bottom to prevent accidents. Many anti-pinch windows use Hall sensors to determine the glass position. If an obstacle blocks the glass during ascent, the power window immediately stops rising and lowers all the way to achieve anti-pinch functionality.

Do I need to sign for confirmation if I fail Subject 2?

Theoretically, whether you pass or fail the Subject 2 exam, you need to sign the score sheet for confirmation (electronic score sheets can also be signed). However, in practice, it usually doesn't matter even if you don't sign, as the score will still be recorded and uploaded. Just to be safe, it's best to sign and confirm your score after each exam. Signing the score sheet doesn't mean you've passed the exam. Theoretically, you need to collect the score sheet and sign it regardless of whether you pass or fail. In practice, many candidates who know they've failed don't collect the score sheet to sign but leave the exam site directly. The score sheet records the candidate's exam results, so checking your score will let you know whether you've passed. If you fail the Subject 2 exam on the first attempt, you can retake it once. If you don't take the retest or still fail the retest, the exam ends, and the applicant should reschedule the exam after ten days. Within the validity period of the driving skill test permit, the number of scheduled exams for Subject 2 and Subject 3 road driving skills tests must not exceed five. If you still fail the fifth scheduled exam, the results of other subjects you've passed will be invalidated.
