What Causes the Noise When a Car Encounters Bumps?

What does it mean when a car fails remote sensing monitoring?

Remote sensing monitoring of a car failing means that the vehicle's exhaust emissions did not meet the standards during remote sensing detection, and it needs to be retested at another remote sensing point. Below is relevant information about automotive exhaust remote sensing detection: Specific meaning: Exhaust remote sensing detection vehicles utilize advanced technologies such as tunable infrared laser diode differential absorption spectroscopy, ultraviolet differential absorption spectroscopy, weak signal detection technology, and image recognition technology. By leveraging the fact that different pollutants absorb light waves of varying frequencies differently, the absorption spectrum can serve as a 'fingerprint' to identify different gas molecules, determining their composition and concentration based on the position and intensity of the absorption lines. Working principle: The measurement of CO and CO2 in vehicle exhaust employs near-infrared laser diode absorption spectroscopy technology, while the measurement of NO and HC uses ultraviolet differential absorption spectroscopy technology with a deuterium lamp as the light source. This enables automatic remote sensing of multiple pollutants in vehicle exhaust emissions during actual driving, including CO, CO2, NO, HC, and exhaust smoke density, with real-time output of monitoring results. Combined with vehicle identification technology, measures can be taken against vehicles exceeding emission standards to improve air quality.

Will points be deducted for touching the dotted line during parallel parking?

Touching the dotted line during parallel parking will result in a 10-point deduction. The following are precautions for the Subject 2 driving test: 1. Mock test: The purpose of a mock test is to familiarize candidates with the test environment and allow the instructor to point out areas prone to point deductions. Therefore, mock tests are absolutely essential; thorough preparation is key to performing your best. 2. Ensure adequate sleep: Make sure to get a good night's sleep before the test day to avoid involuntary nervousness or dizziness during the test. 3. Bring your ID card: Always bring your ID card to the test. Without it, you cannot take the test. After all the preparation, don't let the absence of an ID card prevent you from taking the test. Additionally, turn off your mobile phone during the test, as any activity from the phone may be considered cheating.

What Causes Excessive Transmission Fluid Temperature?

The reasons for excessive transmission fluid temperature are as follows: 1. High engine and coolant temperature: Affects transmission cooling, requires engine repair. 2. Clogged radiator grille: Can be cleaned. 3. Transmission clutch slipping: Generates additional heat, requires coupling repair. 4. Insufficient flow in transmission cooling oil circuit: Requires valve body repair or oil pump replacement. 5. Thermostat sticking: Requires thermostat replacement. Below is additional information about transmissions: 1. Automotive transmission (Transmission): Commonly referred to as "gearbox" in vehicles; often called "speed variator" in industrial machinery, it's a mechanical or hydraulic device for mechanical power conversion. 2. Transmission damage: 90% of transmission failures are caused by high temperature. Transmission overheating shows no obvious symptoms during use, but prolonged high temperature will cause internal seals to age and plastic components to become brittle.

What are the hazards of installing streamers on the front of a car?

The hazard of installing streamers on the front of a car is that it may cause traffic police to mistake the vehicle for a suspicious one and intercept it. The following is an introduction to car decoration: 1. Meaning: Car decoration refers to improving the aesthetics of the car's exterior and interior by adding some accessories, which are called decorative items. 2. Interior: Car interior decoration involves altering the appearance of the car's inner roof, floor, console, and other surfaces by installing, replacing fabrics, or placing ornaments. 3. Exterior: Car exterior decoration involves adding or modifying external parts such as front and rear bumpers, body kits, and spoilers without changing the car's original functions and structure.

How many points are deducted for stalling during the hill start in Subject 2?

During the hill start in the fixed-point parking exercise, stalling once deducts 10 points. Other point deduction items are as follows: After parking, if the right side of the vehicle body is more than 30 cm away from the roadside line, 10 points are deducted; if more than 50 cm, 100 points are deducted; crossing or touching the line results in a 100-point deduction. After parking, if the front bumper is not aligned with the pole line and the deviation is within 50 cm, 10 points are deducted; if the deviation exceeds 50 cm, 100 points are deducted. After parking, if the parking brake is not fully engaged, 10 points are deducted. Failing to complete the start within 30 seconds results in a 100-point deduction. Starting the engine without the gear in neutral or park results in a 100-point deduction. During the start, if the vehicle rolls back less than 30 cm, 10 points are deducted; if it rolls back more than 30 cm, 100 points are deducted. Key points for the hill fixed-point parking operation: Upon hearing the instruction for "hill fixed-point parking" (approximately 20 meters from the pole), turn on the right turn signal, steer appropriately to the right, and slowly drive the vehicle straight along the right side of the road, paying attention to the distance between the vehicle body and the right roadside line. When the vehicle is about 10 meters away from the parking pole, slowly, accurately, and steadily approach the target position. Aim accurately at the target, using a specific point on the parking pole and the windshield (or hood) (this point should be determined during practice due to differences in vehicle models and driver height). When the specific point on the windshield aligns with the parking pole, meaning the vehicle’s bumper is aligned with the parking pole line, stop immediately.
