How to Improve the Kinematic Viscosity of Engine Oil?

The following are methods to improve the kinematic viscosity of engine oil: 1. Use viscosity improvers: Add about 5% viscosity improvers, such as ethylene-propylene viscosity improvers or chloroprene rubber viscosity improvers. This method is low-cost and can also enhance the viscosity index, making it suitable for cold starts. 2. Use high-viscosity base oils: Incorporate 25% of high-viscosity base oils like 500SB or bright stock 150BS. Since these base oils have a viscosity ranging between 24~30, they can be used for adjustment, though this method is more costly. Additional information: 1. Winter oil grades: 0W, 5W, 10W, 15W, 20W, 25W. The symbol 'W' stands for Winter, and the smaller the number before 'W', the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. 2. Summer oil grades: 20, 30, 40, 50. The larger the number, the higher the viscosity, and the higher the applicable maximum temperature.

What is the reason for the right rear turn signal not working on the new Elysee?

The reason for the right rear turn signal not working on the new Elysee could be due to a short circuit fault, a faulty flasher relay, excessive contact gap, and other factors. The specific reasons and solutions are as follows: Short circuit fault: Automotive circuit short circuits can be categorized into soft short circuits and hard short circuits. In the case of a soft short circuit, the fuse will blow with a delay, causing the wiring to heat up, while a hard short circuit will cause the fuse to blow immediately. The solution is to use a short circuit detector to identify and resolve the short circuit fault. Flasher relay fault: Open the flasher relay cover and check if the coil and resistor are intact. If the resistor heats up and the contacts fail to close, press the movable contact. If the turn signal lights up at this point, it indicates a fault with the relay. The solution is to replace the component. Excessive contact gap: This can lead to delayed ignition timing and faults such as the light not working. The solution is to adjust or replace the component.

Is the gas refueling for small cars CNG or LNG?

Automotive natural gas refueling involves compressed natural gas, known as CNG, which is natural gas pressurized and stored in containers in a gaseous state. It shares the same composition as pipeline natural gas, with methane being the primary component. CNG vehicles typically have a driving range of up to 250 kilometers, making them suitable for small household cars, buses, and light-duty trucks. Applications of Compressed Natural Gas: Compressed natural gas is an ideal alternative fuel for vehicles, with application technologies that have matured over decades of development. It features low cost, high efficiency, no pollution, and safe, convenient usage, demonstrating strong growth potential. Natural gas refueling stations are generally categorized into three basic types: fast-fill, slow-fill, and a combination of both. Limitations of Compressed Natural Gas: While using CNG as automotive fuel reduces atmospheric pollution, natural gas itself is a resource with limited reserves and is already a primary energy source for urban living. Its application in vehicles further exacerbates its scarcity. This approach may not be as effective as fully utilizing the already scarce petroleum resources. For now, the reliance on petroleum as the primary energy source for vehicles may remain unchanged. Compressed natural gas contains significant amounts of methane, a greenhouse gas that also contributes to ozone layer depletion (O3, another greenhouse gas). Leaks can pose substantial hazards. Methane combustion produces water and carbon dioxide. While water is harmless, the chemical reaction generates considerable amounts of carbon dioxide, another greenhouse gas.

Can I Use the Manual Lane with ETC Installed?

With ETC installed, you can use the manual payment lane, but you need to remove the ETC card and hand it to the toll collector. When using the manual lane, be sure to stop the vehicle, take the card out of the OBU device, and let the toll collector swipe the card to obtain exit information. When passing through the toll station, proceed in an orderly manner and avoid cutting in line to prevent congestion in the manual lane. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a specialized method for collecting tolls on roads, commonly used on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principles: Highways have one or more ETC lanes. Through microwave short-range communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane, and using computer networking technology for backend settlement with banks, the system allows vehicles to pass through toll stations without stopping to pay tolls. This is based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line. Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass through toll stations without stopping. Reduced wear and tear: Saves costs by minimizing frequent starts and stops, lowering vehicle wear and fuel consumption. Improved efficiency: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" explicitly states the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020." Future possibilities: In addition to improving the convenience of ETC installation and usage, future efforts will promote ETC use for trucks and explore deeper integration of ETC systems with smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle ahead stops, maintain a distance of over 10 meters to prevent accidental toll payment for the vehicle ahead. The ETC lane recognition speed is 20 km/h. Driving too fast may result in failure to read the vehicle's device information and toll deduction failure. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, may render the tag invalid. It can be taken to the bank where the ETC card was issued or a highway service office for inspection. If the issue is not caused by human interference, reactivation may be sufficient. When using a debit card linked to ETC, insufficient balance may cause toll deduction failure. Follow the guidance of on-site staff to use the manual MTC lane with cash or card payment. Thick windshields may cause poor signal reception, especially for vehicles that have had windshield replacements after accidents or modifications.

What does the yellow fuel tank light mean?

When the yellow fuel tank light on the car dashboard illuminates, it serves as a warning that the remaining fuel is low or the fuel pump is experiencing high temperatures. Immediate refueling or seeking professional maintenance personnel for troubleshooting and repair is necessary. Typically, when the yellow fuel gauge light comes on, there is still more than 12.5% of fuel remaining in the tank, approximately around 8 liters. The distance the car can travel after the fuel light comes on varies depending on the fuel tank capacity of different vehicle models and driving conditions. When the fuel tank light turns yellow, you should promptly refuel at the nearest gas station to avoid running out of fuel while driving. It is advisable to control your speed reasonably, turn off unnecessary electrical devices in the car such as air conditioning and music, and slightly close the windows to reduce wind resistance. Try to drive on flat road sections and plan your route carefully to avoid taking wrong turns and consuming extra fuel. When the fuel level drops below the fuel pump, the fuel pump lacks sufficient fuel for cooling, and the more fuel is consumed, the more severe the heating of the fuel pump becomes, which can shorten its lifespan. High temperature phenomenon in the fuel pump: Modern gasoline vehicles mostly use electric fuel pumps and electronic fuel level sensors, both of which require immersion in gasoline for cooling. If the gasoline level is too low, the cooling of the fuel pump will be significantly affected, not only reducing the pump's lifespan but also potentially causing fuel line blockages. It is essential to seek professional help to troubleshoot and eliminate safety hazards promptly. During daily driving, it is important to always monitor the remaining fuel level in the tank. This is usually done by observing the readings on the vehicle's fuel gauge. If there are no other issues, the fuel level will be accurately reflected on the gauge. The dashboard fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by car manufacturers is measured from the bottom of the tank to the safety limit, with additional space remaining from the safety limit to the tank opening. This extra space is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
