Application Range of Gear Oil 85w140?

Gear oil 85w140 is typically suitable for use in temperatures ranging from -16°C to 50°C throughout the year. Functions of gear oil: Gear oil should possess excellent anti-wear properties, load-bearing capacity, and appropriate viscosity. It should also have good thermal oxidation stability, anti-foaming characteristics, water separation capability, and rust prevention performance. Since gear loads generally exceed 490 MPa, and hypoid gear face loads can reach up to 2942 MPa, gear oil accounts for approximately 6%-8% of the total lubricant consumption. Gear oil is a high-performance lubricant. Properties of gear oil: Appropriate viscosity and good viscosity-temperature characteristics are fundamental properties of gear oil. Higher viscosity results in a thicker lubricating oil film and relatively greater load-bearing capacity. Extreme pressure anti-wear performance is the most important and distinctive characteristic of gear oil, which prevents tooth surface wear, scuffing, and scoring during operation.

What Container Should Be Used for Gasoline?

The best container is a glass barrel, which does not deteriorate over long-term storage, but the downside is that it is fragile and inconvenient to transport. Metal barrel container: Metal barrels can also hold gasoline because even if static electricity is generated, the metal barrel conducts electricity, allowing the charge to transfer easily without accumulating, thus preventing sparks. Of course, the best container is still a glass barrel, which does not deteriorate over long-term storage, but the downside is that it is fragile and inconvenient to transport. Storage location for gasoline barrels: Gasoline barrels should be placed in areas where they are unlikely to be knocked over, not in kitchens, stairwells, under beds, or near any fire sources. When refueling motorcycles or cars, choose an open area with no open flames nearby. After refueling, promptly tighten the cap and wipe off any spilled gasoline.

Should You Press Both the Clutch and Brake When Stopping at a Traffic Light?

When encountering a traffic light, it is necessary to press both the clutch and brake simultaneously. This is because during deceleration, the gear may not match the engine speed, leading to a dragging gear situation. Only by pressing the clutch can the power connection between the transmission and the engine be cut off, allowing for deceleration without affecting the engine. Short Duration: If the remaining time of the traffic light is very short—meaning it will soon turn green—you can keep pressing the brake. Once the light turns green, release the brake and press the accelerator to quickly move away. Low Traffic Volume: If the traffic light is about to turn green, you can control the throttle to try to reach the queue point when the light changes. If the traffic starts moving at this point, you can directly shift to second gear and go. If a brief stop is needed, use first gear with the clutch halfway engaged, then proceed to start and go.

What is the Difference Between Tire Pressure Monitoring and Tire Pressure Warning?

The difference between tire pressure monitoring and tire pressure warning is that tire pressure monitoring allows for a direct view of tire pressure, while tire pressure warning is merely an alert system. Below is an introduction to tire pressure monitoring and tire pressure warning: 1. Hazards of improper tire pressure: Both underinflation and overinflation are harmful and can trigger the tire pressure monitoring or warning system. Insufficient tire pressure can also lead to excessive tire wear, poor vehicle control, reduced fuel efficiency, and may even cause wheel deformation. 2. Normal tire pressure values: It is generally recommended to maintain tire pressure between 2.2-2.5 bar. In winter, tire pressure should be slightly higher than in summer, but it is best not to exceed 2.7 bar. In summer, tire pressure can be appropriately reduced by 0.1-0.2 bar. The tire pressure for drive wheels should be slightly higher than that for non-drive wheels, and tire pressure should also increase correspondingly with heavier loads.

What is ETC?

ETC stands for Electronic Toll Collection in Chinese. It is currently the most advanced toll collection method for roads and bridges in the world. It utilizes dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station. ETC employs dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station. It uses computer networking technology to perform backend settlement processing with banks, thereby achieving the goal of vehicles passing through highway or bridge toll stations without stopping to pay tolls. Fully automated electronic toll collection (ETC) is one of the service functions of the intelligent transportation system, particularly suitable for use in highway or busy bridge and tunnel environments. Currently, there are dedicated ETC toll lanes at highway toll stations. Vehicle owners only need to install a transponder card on the windshield and preload funds. When passing through the toll station, there is no need for manual payment or stopping, as the highway toll will be automatically deducted from the card, enabling automatic toll collection. This system takes less than two seconds per vehicle, and the traffic capacity of ETC lanes is 5 to 10 times that of manual toll lanes. Using a fully automated electronic toll collection system can make highway toll collection paperless and cashless, fundamentally eliminating the loss of toll revenue and solving financial management chaos in highway toll collection. Additionally, implementing a fully automated electronic toll collection system can save on infrastructure and management costs. Documents required to apply for ETC: The vehicle owner's original valid ID card, the original and a copy of the vehicle registration certificate (the page with the most recent annual inspection stamp must 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 major bank branches, a debit or credit card from the corresponding bank must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the funds as a security deposit when binding with a debit card. ETC deduction principles: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, backend settlement is performed with banks using computer networking technology, achieving the goal of vehicles paying tolls without stopping at road or bridge toll stations. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of queuing and waiting. Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution. Reduced wear and tear: Saves costs by reducing the frequency of vehicle starts and stops, lowering wear and fuel consumption. Improved efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC newer, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation smart cards in key urban clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC adoption rate for passenger vehicles, efforts will be made to promote ETC usage for trucks in the future. There will also be exploration of deep integration between the ETC system and smart transportation development directions such as vehicle-to-vehicle communication and vehicle-to-infrastructure coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of more than 10 meters to prevent automatic sensing and payment for the vehicle ahead, in case the vehicle ahead has a faulty ETC device or no ETC device at all. The recognized speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle's device information cannot be read, leading to failed deductions. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will render the electronic tag invalid. It can be taken to the bank where the ETC card was issued or the highway service office 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 will also cause deduction failures. Follow the guidance of on-site staff to use the manual MTC lane and pass by paying with cash or swiping a card. Excessive thickness of the car windshield may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after accidents or for those who have modified their windshields.

Can I make a U-turn when the navigation says to?

You cannot rely entirely on navigation; you should drive safely according to the actual road conditions. Here are the relevant details: 1. Updates needed: Navigation maps require regular updates. If not updated in time, some roads may not be included in the navigation map, or there may be intersections marked with "No U-turn" or "No left turn" signs that the navigation hasn't updated. Making a U-turn at such locations may result in a traffic violation. 2. Article 39: Traffic management departments of public security authorities can implement measures such as guidance, traffic restrictions, or prohibitions for motor vehicles, non-motor vehicles, and pedestrians based on specific road and traffic conditions. In cases of large-scale public events or extensive construction, traffic restriction measures or decisions directly affecting public road traffic activities should be announced to the public in advance.
