Can I Use the Highway Without ETC After Installation?

It is possible to use the highway without ETC. According to the State Council's regulations, vehicles without ETC installed by 2020 will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, requiring drivers to pay tolls manually. Additionally, newly installed ETC devices cannot be used immediately on highways; they must be activated first. During free holiday periods, highways can still be used. For vehicles with ETC installed, passing through ETC lanes during these periods will not incur charges. ETC Billing Principle: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's onboard electronic tag (installed on the windshield) and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks in the background. This allows vehicles to pass through toll stations without stopping, based on the principle of "pass first, pay later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions since vehicles do not need to stop at toll stations; Cost-saving: Reduces vehicle wear and fuel consumption by minimizing frequent starts and stops. Users also enjoy a 5% discount on toll fees; Improved efficiency: ETC lanes can theoretically increase traffic flow efficiency by 2-3 times, making traditional ETC systems faster, more advanced, and more efficient. Compared to license plate payment systems, 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 urban clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." The plan also sets a target of "50% ETC usage rate for road passenger vehicles by 2020" in its main indicators for comprehensive transportation development. Future possibilities: Beyond improving the convenience of ETC installation and increasing its usage rate among passenger vehicles, future efforts will focus on promoting ETC adoption for trucks and exploring deeper integration of ETC systems with smart transportation initiatives like 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 usage.

Which is the High Gear, L or H?

L stands for low gear, while H represents high gear. High gear is used when road conditions are favorable, the engine has sufficient power, or the vehicle is lightly loaded. Driving in high gear allows for higher speeds, smaller traction force, higher engine RPM, lower fuel consumption, and reduced engine wear, making it suitable for long-distance travel on good roads. Low gear: Low gear features a large speed ratio and slower driving speed, enabling the drive wheels to obtain greater torque and increased traction. Therefore, it is used when starting, climbing steep slopes, or navigating difficult road sections with high driving resistance. However, low gear results in slower vehicle speed, higher engine RPM, increased engine temperature, and higher fuel consumption. Thus, driving in low gear should not be prolonged. Medium gear: Medium gear serves as a transitional gear between low and high gears. It is typically used when turning, crossing bridges, meeting other vehicles, driving on general slopes, or passing through moderately difficult road sections. However, prolonged driving in medium gear is also not advisable. Downshifting (from high gear to low gear): When downshifting is necessary, reduce the vehicle speed to a certain level, then release the accelerator pedal while depressing the clutch pedal. Shift the gear lever from high gear to neutral, then release the clutch pedal and briefly press the accelerator ("empty throttle"). Next, depress the clutch pedal again and shift the gear lever to the next lower gear. Finally, quickly release the clutch pedal to the semi-engaged position, then smoothly press the accelerator pedal while gradually releasing the clutch pedal to continue driving. The principle of downshifting with "empty throttle" is: more "empty throttle" when the vehicle speed is high, less when it is low; more "empty throttle" when the engine RPM is low, less when it is high; more "empty throttle" on flat roads, less when going uphill.

Can 95 and 98 be mixed?

92 gasoline and 95 gasoline cannot be mixed because the isooctane content of 92 gasoline and 95 gasoline is different. 92 gasoline is suitable for engines with low compression ratios, while 95 gasoline is suitable for engines with high compression ratios. If 92 gasoline is added to a car that should originally use 95 gasoline, abnormal combustion will occur, leading to knocking. Knocking not only damages the combustion chamber but also directly affects the normal operation of the engine, and in severe cases, may cause engine damage. If 95 gasoline is added to a car that should originally use 92 gasoline, although it will not damage the engine, 95 gasoline is more expensive than 92 gasoline, resulting in waste. The differences between 92, 95, and 98 gasoline: Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock properties, and its octane number is defined as 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with its octane number defined as 0. If the gasoline is labeled as 92, it means that the gasoline has the same anti-knock properties as standard gasoline containing 92% isooctane and 8% n-heptane. The principles for 95 and 98 are the same. Handling methods for adding the wrong gasoline: If the gasoline added has a higher octane number than the car's specified gasoline, for example, if 95 is added when 92 is specified, you can simply switch back to 92 gasoline after the current fuel is consumed. If the gasoline added has a lower octane number than the car's specified gasoline, for example, if 92 is added when 95 is specified, you only need to add a high anti-knock fuel additive. Of course, you can also directly drain the fuel and refill with 95 gasoline. To find out which gasoline your car requires, you can refer to the car's user manual or check the fuel grade marked on the fuel tank cap.

Should Automatic Transmission Cars Shift to Neutral at Red Lights?

For longer red lights, you can choose to shift to neutral while waiting, which helps reduce fuel consumption and minimizes wear on the transmission. For shorter red lights, staying in drive (D) is acceptable. Below are some uses and tips regarding the neutral gear: 1. Temporary parking. When the vehicle needs to stop temporarily, such as waiting briefly for someone, shifting to neutral is suitable. For extended waiting periods, it's recommended to turn off the engine. 2. Towing. If the vehicle requires repairs or needs to be towed for other reasons, the gear must be shifted to neutral. 3. Starting and stopping. Using neutral during startup and temporary stops reduces wear on the car.

What does ESP mean?

ESP is the abbreviation for Electronic Stability Program, which is an extension of the functions of the anti-lock braking system (ABS) and traction control system (TCS) in vehicles. It is also part of the vehicle's active safety system. ESP primarily controls the longitudinal and lateral stability of the vehicle, ensuring that it moves according to the driver's intentions. ESP mainly consists of three major components: sensors, actuators, and the electronic control unit (ECU). The sensors include wheel speed sensors, steering angle sensors, lateral acceleration sensors, yaw rate sensors, and brake master cylinder pressure sensors. The actuators include traditional braking systems and hydraulic modulators. The electronic control unit works in conjunction with the engine management system, allowing for intervention and adjustment of the engine's power output.

How to Open the Fuel Tank Cap of Borgward?

Borgward's fuel tank cap can be opened simply by pressing it when the vehicle is unlocked. The fuel tank cap refers to the box on the car used for storing gasoline, which is square in shape, made of stainless steel, and has excellent sealing. It is necessary to clean the fuel tank regularly, as gasoline usually contains impurities. If the fuel tank has not been cleaned for a long time, the mixture inside can become excessive, affecting the use of gasoline and the performance of the car. Borgward cars originated in Bremen, Germany. The Borgward BX7 is one of its models, powered by a 2.0T turbocharged direct injection engine with a maximum power of 165 kW and a maximum torque of 300 Nm, paired with an Aisin 6-speed automatic transmission.
