What Happens When Gasoline Quality is Poor?

Poor gasoline quality can lead to increased carbon deposits in the combustion chamber, cause knocking combustion, and result in reduced power and elevated temperatures. Below are the effects of gasoline quality on vehicles and the manifestations of fuel quality. Impact of gasoline quality on vehicles: Gasoline is the heart of a car, and whether its quality meets the national standards for automotive gasoline has a significant impact on the vehicle. Poor fuel quality can 'poison' the car, with minor effects like reduced acceleration and severe cases causing engine damage that requires disassembly for repair. Abnormal car malfunctions are often caused by the use of substandard gasoline. Manifestations of fuel quality: Standard fuel appears colorless, transparent, or golden yellow, while substandard fuel looks cloudy, dark, dull, and may contain suspended impurities. Qualified fuel has a faint, pleasant smell; substandard fuel, if diluted with water, may have a weak odor or extreme pungent and sour smells, leading to exhaust emissions with abnormal odors. Standard gasoline feels cool when dripped on the hand, while slow evaporation or residue indicates poor quality. Cars using substandard fuel may produce noticeable abnormal noises during driving, accompanied by vibrations. Shaking gasoline will produce bubbles; the faster the bubbles disappear, the better the fuel quality.

Can 3 points deducted for no annual inspection be deducted from someone else's license?

Can 3 points deducted for no annual inspection be deducted from someone else's license? As long as the fine is paid, the demerit point system will automatically reset the previous demerit points from the next demerit point cycle, i.e., the second year, after the fine is paid. Regulations on the deduction of points for motor vehicle driving licenses: If a motor vehicle driver's demerit points do not reach 12 points within a demerit point cycle and the imposed fine has been paid, the demerit points will be cleared. If the demerit points have not reached 12 points but there are still unpaid fines, the demerit points will be carried over to the next demerit point cycle. Precautions regarding the deduction of points for motor vehicle driving licenses: When a Class C driving license accumulates 12 demerit points within a demerit point cycle, the driver must attend a training course at the vehicle management office as required and then take an exam. The driving license can only be used again after passing the exam. During the period before passing the exam, driving on the road is not allowed, otherwise it will be considered as driving without a license.

What does 'cruise' displayed on the car mean?

cruise refers to the car's electronic cruise control system. Generally, when the vehicle speed exceeds 20km/h, pressing the cruise button will activate the cruise control mode, where the engine computer automatically controls the speed without the need to press the accelerator pedal. The driver only needs to steer the wheel. When the green cruise indicator light on the dashboard illuminates, it indicates that the cruise control switch is now activated. Below is a detailed classification of cruise functions: 1. Speed Cruise Control: This is the most common type. The basic operation involves activating the cruise mode and then selecting the desired speed, allowing the driver to release the accelerator pedal while maintaining the set speed. The speed can be adjusted using control buttons (or levers) during driving. To cancel the cruise setting, simply press the brake or turn off the cruise switch. 2. Speed Limiter Cruise: This is very similar to speed cruise control, with the key difference being that after setting the speed limit, the driver must keep their foot on the accelerator pedal to maintain the set speed. Once the set speed is reached, the computer automatically determines the required fuel supply. Unless the accelerator is pressed deeply and quickly, slight increases in the accelerator will have no effect. 3. Adaptive Cruise Control: The most notable feature of adaptive cruise control is the addition of radar or infrared detectors, giving the cruise system 'artificial intelligence.' It helps the driver maintain higher safety in conditions like fog or sandstorms and can perform advanced driving tasks such as following another vehicle, similar to an experienced driver.

What is the national emission standard for a 2004 vehicle?

Vehicles from 2004 comply with the China II emission standard. Here are several ways to check your vehicle's emission standard: 1. Refer to the environmental protection label issued during vehicle inspection. 2. Inquire at the vehicle management office. 3. Check the vehicle model directory on the Motor Vehicle Environmental Protection Website. Below are the implementation timelines for emission standards: 1. China I standard, implemented nationwide on July 1, 2001, mainly imposing restrictions on carbon monoxide, hydrocarbons, and particulate emissions. 2. China II standard, implemented nationwide on July 1, 2004, requiring a 30% reduction in carbon monoxide and a 55% reduction in hydrocarbons and carbon oxides. 3. China III standard, implemented nationwide on July 1, 2007, requiring a 40% reduction in total pollutant emissions compared to China II. 4. China IV standard, implemented nationwide on July 1, 2010, requiring a 50% to 60% reduction compared to China III. 5. China V standard, implemented nationwide on January 1, 2018, requiring a 25% reduction in nitrogen oxide emissions compared to China IV. 6. China VI standard, with China VIa implemented nationwide on July 1, 2020, and China VIb on July 1, 2023.

How to Turn Off the Engine Auto Start-Stop?

Methods to turn off the auto start-stop are as follows: 1. Press the auto start-stop button directly (a circular arrow containing the letter A), and the dashboard will indicate that the system is turned off. 2. If you want to use this function again, press the button to turn it back on. 3. After turning on the auto start-stop, pressing the brake pedal slightly harder will turn off the engine, and pressing the brake again will start the engine, thereby saving fuel. The following are the disadvantages of auto start-stop: 1. Higher maintenance costs for the battery and starter: Frequent engine starts and stops can damage related components, such as the starter and battery. Although vehicles with auto start-stop systems use enhanced starters and batteries, in actual use, their failure rates are higher than those of ordinary vehicles without auto start-stop systems. 2. Poor user experience: Different models from various brands have different designs for the auto start-stop system. Some models have poor start-stop logic, with inaccurate intervention timing. Sometimes, the system does not activate even during prolonged stops. 3. More fuel consumption in traffic jams: In severe traffic jams, if the engine stops for a long time, the combustion chamber temperature drops, and unburned hydrocarbons and paraffin can form carbon deposits on the cylinder walls. If the fuel quality is poor, the situation can worsen. Carbon deposits increase fuel consumption and reduce power. The auto start-stop function, designed to reduce fuel consumption, may instead increase it.

What is the appropriate slope height for car passage at the entrance?

Generally, it should not exceed 15%. The straight gentle slope within 3.6 meters at the entrance and exit should be 7.5%, and the curved gentle slope within 2.4 meters should also be 7.5%. This prevents the front and rear chassis of the vehicle from scraping. Relevant introduction to car ramp slopes: Straight ramp: The ramp width should not be less than 1200, and the slope should not exceed 1:12. Double-turn ramp: The ramp width is 1200, the slope is 1:12, and the depth of the ramp start, end, and rest platform is 1500. L-shaped ramp: The ramp width is 1200, the slope is less than 1:12, and the depth of the ramp start, end, and rest platform is 1500. Slopes greater than 10%: When the slope exceeds 10%, gentle slopes should be set at both the upper and lower ends. The horizontal length of the straight gentle slope section should not be less than 3.6m, and the gentle slope gradient should be half of the ramp slope. The horizontal length of the curved gentle slope section should not be less than 2.4m, the curve radius should not be less than 20m, and the midpoint of the gentle slope section should be the original start or end point of the ramp.
