Does a faulty turbocharger affect the engine?

Yes, it does. A faulty turbocharger can lead to engine power loss, black smoke from the exhaust pipe, oil burning, and insufficient engine oil. Below is more information about turbochargers: 1. Introduction: A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. 2. Working Principle: It utilizes the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber. This turbine, in turn, drives a coaxial impeller, which compresses air delivered through the air filter pipe, pressurizing it before it enters the cylinders. As the engine speed increases, the exhaust gas expulsion speed and turbine rotation speed also rise in sync, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel. By adjusting the fuel quantity and engine speed accordingly, the engine's output power can be enhanced.

Is a Car Considered Totaled if It Gets Flooded?

This depends on the severity of water ingress. Here is some information regarding vehicle scrapping: 1. Legal provisions: According to the 'Mandatory Scrapping Standards for Motor Vehicles', small private passenger vehicles have no usage lifespan limit, but will be guided for scrapping after reaching 600,000 kilometers, though not mandatory. 2. Scrapping conditions: In practical use, these older vehicles face numerous inconveniences, with the biggest obstacles being safety inspections and emission tests, commonly known as annual inspections and emissions. As per regulations, vehicles failing annual inspections are prohibited from road use, and those failing three consecutive annual inspections will be mandatorily scrapped.

Does Taiwan drive on the left or right side?

All vehicles across the country now drive on the right side, and post-recovery Taiwan has also legally adopted right-hand traffic. Below is relevant information about vehicle driving: 1. Precautions: Strictly prevent speeding. Typically, when driving at 72 km/h, a driver with normal 5.1 vision will experience a decline to 4.8, significantly reducing their ability to discern surrounding environments and pedestrians. Speeding disrupts the vehicle's operational indices in specific conditions, increases its workload and stress, and accelerates wear and damage to components. 2. Techniques: To handle rapidly changing traffic conditions on the road, drivers must make quick judgments within 0.75 seconds and take appropriate technical measures to ensure traffic safety. When driving without alcohol consumption, the reaction time from visual perception to applying the brakes upon detecting a hazard ahead is 0.75 seconds.

Why is the reversing radar not responding?

It may be due to sensor malfunction or poor internal contact. Here is an introduction to reversing radar: 1. Introduction: Reversing radar, also known as "reverse collision avoidance radar" or "parking assist device." 2. Components: Mainly consists of ultrasonic sensors, controllers, and displays. 3. Function: The reversing radar is a safety auxiliary device when parking or reversing the car. It can inform the driver of surrounding obstacles through sound or more intuitive displays, eliminating the troubles caused by the driver's need to look around when parking, reversing, or starting the vehicle, and helping the driver overcome blind spots and unclear vision defects.

Do I need to change the oil if I drive 3,000 kilometers a year?

It is not advisable to determine whether an oil change is needed simply based on time or mileage. The decision to change oil depends on many factors, including engine condition and oil quality. Here is a relevant analysis: 1. Engine Condition: A new car's engine is clean internally, with little carbon buildup or other impurities, so the oil change interval can be appropriately extended. However, it should not exceed 7,500 kilometers. For older engines, especially those lacking maintenance, there is often more carbon buildup and sludge inside. New oil can easily become contaminated, leading to discoloration and degradation, so the oil change interval should be shortened accordingly. 2. Oil Quality: Oil has two main standards: quality grade (API) and viscosity (SAE). The quality grade typically ranges from SC, SD up to SM, with higher grades indicating better quality. Modern cars, especially passenger vehicles, often have high-revving engines that demand higher-quality oil. Generally, SF-grade or higher oil provides good oxidation resistance, wear resistance, detergency, and viscosity stability under high-temperature and high-shear conditions, offering reliable protection for the engine. Its quality remains stable for a long time and can fully meet a 5,000-kilometer oil change interval under normal conditions. However, if using SD or even SC-grade oil, the oil change interval should be reduced to 3,000 kilometers or even shorter. 3. Environmental Impact: The environment also affects oil performance. High temperatures, extreme cold, and dusty conditions can accelerate oil degradation. Therefore, it is important not only to choose oil with the appropriate grade and viscosity for the environment but also to shorten the oil change interval accordingly. The specific adjustment depends on the situation, but generally, reducing the interval by 1/5 to 1/3 is advisable.

What materials are needed to apply for ETC for a car?

According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the following materials are required: the original valid ID card of the vehicle owner, the original and a copy of the vehicle registration certificate (the page with the most recent annual inspection stamp should be provided). If applying on behalf of someone else, the original valid ID card of the agent is also required. If applying for ETC through bank branches, a debit or credit card from the corresponding bank is needed. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding with a debit card. Additionally, the vehicle insurance policy for the current year is required. For corporate applications, the agent's ID card (or driver's license), the company's organization code certificate (or business license), and the company seal are necessary. ETC Deduction Principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, and using computer networking technology for backend settlement with banks, the system achieves the purpose of collecting tolls without requiring vehicles to stop at toll stations. All this is based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions, minimizing pollution by allowing vehicles to pass through toll stations without stopping. Reduced wear and tear: Saves costs by reducing the frequency of vehicle starts and brakes, thereby lowering wear and fuel consumption. Improved efficiency: ETC lanes can theoretically improve traffic flow efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More Policy Support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." The plan also set a target of "achieving a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of comprehensive transportation development during the 13th Five-Year period. More Future Possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC use for trucks and explore deeper integration of ETC systems with smart transportation directions such as vehicle-to-vehicle communication and vehicle-to-infrastructure coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of more than 10 meters to prevent automatic sensing and payment for the vehicle in front, especially if its ETC device is faulty or absent. The recognition speed for ETC lanes is 20 km/h. Driving too fast may result in failure to read the vehicle's device information and subsequent deduction failure. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will render the tag invalid. It can be taken to the bank where the ETC card was issued or a highway service center for inspection. If the detachment or loosening is not due to human factors, reactivation is sufficient. When using a debit card bound to ETC, insufficient balance may cause deduction failure. Follow the guidance of on-site staff to use manual MTC lanes and pay with cash or card. Poor sensing may occur due to overly thick windshields. This is particularly important for vehicles that have had their windshields replaced after accidents or for those with modified front windshields.
