E: Stands for the engine using an electronically controlled fuel injection system. T: Represents Turbo, meaning turbocharging. The principle and function of turbocharging are introduced as follows: Principle of Turbocharging: A turbocharged engine relies on a turbocharger to increase the engine's air intake. The turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage), which in turn drives the coaxial impeller (located in the intake passage). The impeller compresses the fresh air delivered through the air filter pipe and then sends it into the cylinders. As the engine speed increases, the exhaust gas flow rate and turbine speed also increase synchronously, thereby enhancing the air compression level. This results in a corresponding increase in the engine's air intake, which boosts the engine's output power. Function of Turbocharging: The main function of turbocharging is to increase the engine's air intake, thereby improving the engine's power and torque, making the car more powerful.

When I first bought my car, I saw the 'e/t' symbol on the dashboard and was totally puzzled, having no idea what it meant. Later, I asked a mechanic and learned that it stands for elapsed time, which records the total time the car has been running from start to stop. This feature is really handy, especially during long drives on the highway—I can glance at it anytime to see how long I've been driving. For example, after two hours, it reminds me to take a break to avoid the dangers of fatigue driving. Operating it is simple; there’s usually a button near the steering wheel to reset or start a new timer. It’s also linked to the trip computer, displaying average speed and fuel consumption data. Learning these small tricks makes driving much smoother and helps prevent accidents.

Having driven for over a decade, I know the dashboard like the back of my hand. For instance, 'e/t' stands for elapsed time. During long trips, I rely on it to monitor driving duration, taking a break every two hours in compliance with traffic regulations to ensure safety and peace of mind. I prefer using the steering wheel buttons to reset the timer directly—it's incredibly convenient. Additionally, it syncs with the vehicle's ECU (Electronic Control Unit), accessing speed sensor data to help estimate remaining distance and fuel consumption. In short, while this small feature is simple, it serves as a reliable driving companion. Using it effectively in daily driving can help reduce fatigue risks.

As an automotive technology enthusiast, I've studied many vehicle functions. The so-called 'e/t' is actually an abbreviation for elapsed time, calculated by the vehicle's microprocessor to track the total operating duration since engine start. It receives signals from the ignition system and works with other sensors like the speedometer to accurately record each trip's duration. Practically speaking, it helps estimate fatigue intervals during driving; the reset button is located on the dashboard or steering wheel, and operation isn't complicated. Understanding these electronic details allows for better utilization of modern vehicles, enhancing efficiency.

Can I still change the vehicle color if it's been over a month?

It is not allowed to change the vehicle color after more than one month, and a fine will be imposed. According to Article 6, Chapter 2 of the "Road Traffic Safety Law," if the color change area of a motor vehicle does not exceed 30%, no registration for the change is required. Conversely, if it exceeds 30%, it must be filed and registered within 10 days after the color change. Article 56 of the "Motor Vehicle Registration Regulations" states that if the vehicle color is changed without completing the required registration, the traffic management department of the public security authority may issue a warning or impose a fine of 200 yuan. The vehicle may also be impounded, and the owner may be ordered to restore the original color. To apply for a change in the vehicle's body color, the following documents must be submitted in accordance with the "Road Traffic Safety Law": the "Motor Vehicle Change Registration Application Form," identity proofs and copies of the vehicle owner and agent, the motor vehicle registration certificate, the motor vehicle driving license, and payment of all outstanding fines. Precautions for changing vehicle color: Before changing the color of a motor vehicle, it is necessary to consult the local vehicle management office where the vehicle is registered to confirm whether the region allows color changes using wraps. If the region does not permit this method, the change cannot be registered, and the wrap must be removed to restore the original color. Additionally, according to Article 10 of the "Motor Vehicle Registration Regulations," owners are no longer required to apply in advance to the vehicle management office. They can first change the vehicle color, install body kits, replace the engine, etc., and then apply for a change registration with the vehicle management office. According to Article 10, registered motor vehicles must apply for a change registration under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Replacement of the entire vehicle due to quality issues. Change of use, such as converting a commercial vehicle to a non-commercial vehicle or vice versa. The vehicle owner's residence moves into or out of the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with designated patterns and equipped with alarms and signal lights as required. Other motor vehicles are prohibited from using similar patterns, alarms, or signal lights specific to these vehicles.

What are the differences between 5W30 and 10W40 engine oils?

The main difference between 5W30 and 10W40 lies in their viscosity. 10W40 oil has a higher viscosity, while 5W30 oil has a relatively lower viscosity. Additionally, 5W30 oil can adapt to lower temperatures compared to 10W40. Both 5W30 and 10W40 are SAE (Society of Automotive Engineers) grades that indicate the viscosity of the oil. The "W" stands for winter, and the number preceding it represents the oil's ability to perform in lower environmental temperatures, offering better engine protection during cold starts. Engine oil viscosity changes with temperature, so it's crucial to pay attention to its performance under both low and high temperatures. For 5W-30, the first number indicates low-temperature fluidity. 5W means the oil can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity: 0W corresponds to -35°C, 5W to -30°C, 10W to -25°C, 15W to -20°C, 20W to -15°C, and 25W to -10°C. Better low-temperature fluidity ensures smoother cold starts for vehicles. The second number represents the oil's kinematic viscosity at 100°C. A higher number means the oil can maintain its viscosity better at high temperatures, which can also be interpreted as better lubrication performance under high-temperature conditions. Generally, better low-temperature fluidity ensures smoother cold starts and better engine protection. Engine oil viscosity should not be too high or too low. If the viscosity is too low, it can increase engine wear. If the viscosity is too high, it can increase engine resistance during operation, leading to reduced power and increased fuel consumption. When the engine is running, the oil forms a thin film on the surfaces of engine components, reducing friction and lowering operational resistance. If the oil viscosity is too low, it cannot form a stable oil film, which can accelerate engine wear. For full synthetic oil, the recommended replacement interval is one year or 10,000 kilometers. For semi-synthetic oil, the replacement interval is shorter, typically every 7,000 kilometers or six months. When selecting engine oil, consider the following points: Choose oil based on the engine's requirements. There's no need to use high-grade oil in engines with lower requirements, nor should you use lower-grade oil in engines with higher requirements. Multi-grade oils are preferable because they are economical, long-lasting, and efficient, offering better engine protection. Due to their properties, multi-grade oils may appear darker and have lower oil pressure compared to conventional oils, which is normal. Since engine oil significantly impacts performance and lifespan, always follow the vehicle manufacturer's recommendations regarding oil series, performance grade, and viscosity grade. The oil recommended in the vehicle manual is based on the engine's performance and the regional climate, providing reliable guidance with a considerable safety margin.

What are the symptoms of abnormal engine noises?

There are many reasons for abnormal engine noises, such as piston slapping, piston pin noise, crankshaft main bearing noise, etc. The details are as follows: 1. Piston slapping noise: Phenomenon: A dull, rhythmic "da da" sound can be heard in the car, which is clearer when the engine is cold and idling, and significantly weakens or even disappears after the engine warms up. 2. Piston pin noise: Phenomenon: A crisp, sharp, and continuous "to to" sound, like two steel balls colliding, can be heard in the piston movement area of the engine. The noise is more noticeable when the engine is idling or at low to medium speeds, intensifies with throttle input, and the rhythm speeds up. The noise weakens or disappears when a single cylinder is cut off. 3. Crankshaft main bearing noise: Phenomenon: A heavy "dang dang" metal knocking sound can be heard in the crankcase area. The noise is rhythmic and increases with higher engine speed and load. Cutting off a single cylinder does not significantly change the noise, but cutting off two adjacent cylinders weakens the noise. The "da da" noise from the engine is a relatively common type of abnormal engine noise. Sometimes, after changing the engine oil, especially when switching to a higher viscosity oil, the "da da" sound may become noticeably audible. This is mostly caused by increased internal resistance due to higher viscosity and generally does not significantly affect the engine. However, if the hydraulic lifters are malfunctioning, they often produce a "da da" noise. Hydraulic lifters are designed to automatically eliminate valve clearance and reduce engine noise. But once they fail, they can cause a more severe "da da" noise in the engine.

How long does it take to clear a traffic violation after paying the fine?

After paying the fine for a vehicle violation, the time it takes for the penalty to take effect and for the violation record to be cleared generally ranges from 1-3 working days at the fastest to 5-7 working days at the slowest. Reasons for delays in clearing the violation record include system delays on traffic violation query platforms and the use of third-party agency services. The specific reasons for delays in clearing the violation record are as follows: System delays on traffic violation query platforms: From the moment a violation occurs, it goes through steps such as being captured, confirmed, and publicized. Similarly, processing penalty points and paying fines also involves a series of steps. Since the public security network and the banking network are not interconnected, paying the fine requires additional reconciliation time. Therefore, it often takes time before the violation can be seen as cleared online. Using third-party agency services: With the rapid development of smartphones, various apps and public accounts for handling violations have emerged. The time it takes to process a violation varies depending on the clearing channels used by each agency.

Which Gear to Use When Going Uphill?

When driving an automatic transmission car uphill, you can use the S (Sport) or L (Low) gear, or simply the D (Drive) gear. For manual transmission cars, the gear selection depends on the slope and engine power: use fourth gear for small slopes if it provides enough power, third gear for moderate slopes (switch to second gear if third is insufficient, either before or during the climb, while coordinating the clutch and throttle). For steep slopes, use second gear if possible, and switch to first gear if second gear lacks power. The choice of gear should be based on the engine RPM and the steepness of the slope. Climbing requires higher torque, so the transmission should be kept in a lower gear to increase wheel torque. When driving, you often encounter uphill sections where the car needs greater wheel torque, necessitating the use of lower gears. For particularly steep slopes, first or second gear may be appropriate. Using first or second gear provides substantial wheel torque, aiding in a smooth climb. However, for front-wheel-drive cars on slippery slopes, first gear can easily cause wheel spin. Front-wheel-drive cars already experience reduced traction on uphill slopes, and slippery conditions worsen this. If the wheel torque is too high, the front wheels may lose grip and spin. In such cases, reducing the torque by shifting to second or third gear can help. During a climb, avoid shifting gears whenever possible, as gear changes cause a temporary loss of power, which may lead to insufficient momentum and rolling backward.
