What is the fuel tank capacity of the Baojun 310?

The fuel tank capacity of the Baojun 310 is 30 liters. In the same class, the 2020 Kia Pegas 1.4L Automatic Comfort Sunroof version has a fuel tank capacity of 40 liters, while the 2022 YARiS L ZhiXiang 1.5L CVT Leading PLUS version has a fuel tank capacity of 42 liters. Maintenance of the fuel tank is as follows: Check for fuel leaks in the fuel lines; ensure the vent hole is unobstructed; the filter screen at the fuel filler neck should remain intact; the sealing gasket on the fuel filler cap should also be in good condition. Maintenance of the fuel tank is as follows: Drain any accumulated water and sediment from the fuel tank, and inspect the fuel line connections and valves for any signs of leakage. For fuel tank caps equipped with air and vapor valves, also check that the vent holes are clear. The filter screen at the fuel filler neck should be kept intact to prevent impurities from entering the fuel tank during refueling, which could clog the fuel lines. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel from spilling out while driving. If the owner wants to check the remaining fuel level, they can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is close to E, it indicates that the fuel is almost empty, and when it is near F, it means the fuel level is sufficient.

Is the Transmission the Same for the Bora Legend and the New Bora?

The Bora Legend and the New Bora are equipped with the same engine, although there are slight differences in tuning. Additionally, they share identical transmissions, chassis steering, wheel braking systems, and primary and passive safety features. In terms of control configurations, the Bora Legend has an additional cruise control function, which is its only advantage. On the other hand, the New Bora comes standard with LED daytime running lights across all models, highlighting the distinction between the two. The New Bora is overall larger than the Bora Legend, as it is built on Volkswagen's new MQB platform—the same platform used for the new Sagitar and Lavida—while the Bora Legend remains on the PQ34 platform. As a result, the New Bora offers significantly better space and comfort compared to the Bora Legend.

Can Motorcycle Shock Absorbers Be Filled with Engine Oil?

Motorcycle front shock absorbers should not be filled with ordinary engine oil, as their properties and viscosity are different, and using them in shock absorbers will not achieve good damping performance. Suspension System: In the suspension system, elastic components generate vibrations when impacted. To improve ride comfort, shock absorbers are installed in parallel with the elastic components in the suspension to dampen vibrations. Shock Absorber Working Principle: Most shock absorbers used in automotive suspension systems are hydraulic shock absorbers. Their working principle is that when relative motion occurs between the frame (or body) and the axle due to vibrations, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different orifices. At this time, the friction between the orifice walls and the oil, as well as the internal friction between oil molecules, creates a damping force that converts the vehicle's vibration energy into heat energy of the oil, which is then absorbed by the shock absorber and dissipated into the atmosphere.

What does TPI mean for tires?

TPI=threads per inch, which refers to the number of fabric threads per inch, indicating the density of the fabric. A higher TPI count means lower rolling resistance. Most of a tire's rolling resistance is caused by rubber deformation. Since high-TPI casings contain less rubber, they can more efficiently convert the rider's energy into forward momentum. Tires are not entirely made of rubber; they have internal fibers as reinforcement materials. A higher TPI indicates more fibers per inch. A denser weave means finer fibers, requiring less rubber to fill the gaps; conversely, a less dense weave has thicker fibers and requires more rubber. TPI parameter: TPI is a density reference value. The higher the number, the thinner the tire sidewall, the more challenging the manufacturing process, the higher the material requirements, and the better the air retention.

Do I need to retake the test when switching from manual to automatic transmission?

No, the manual transmission test is for the C1 driver's license, while the automatic transmission test is for the C2 driver's license. If you want to switch, the previous results of Subject 1 will be invalidated, and you will have to retake the test, which is simply not worth it. A manual transmission, also known as a manual gearbox (MT), requires the driver to manually shift gears by moving the gear lever to change the gear engagement inside the transmission, thereby altering the gear ratio to achieve speed changes. Working principles of manual and automatic transmissions: 1. The impeller and turbine form a working pair: They function like two fans placed opposite each other, where the wind from one fan drives the rotation of the other fan's blades, with the wind acting as the medium for kinetic energy transfer. If a liquid is used instead of air as the medium for kinetic energy transfer, the impeller will drive the turbine to rotate via the liquid. By adding a guide wheel between the impeller and turbine, a speed difference between them can be achieved through reaction force, enabling variable speed and torque. 2. Insufficient torque range: Due to the limited torque range of the hydraulic torque converter in automatic transmissions, several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system automatically operates the planetary gears according to changes in engine operation, thereby achieving automatic speed and torque variation. The auxiliary mechanism for automatic gear shifting cannot meet all driving needs, such as parking or reversing, so intervention devices and manual levers are also included, marked with P (Park), R (Reverse), N (Neutral), and D (Drive). Additionally, within the Drive gear, there are "2" and "1" sub-gears for starting or climbing slopes.

How many kilowatt-hours does a fast charge for new energy vehicles consume in one hour?

Charging for one hour consumes 0.22 kilowatt-hours. General situation: A 48v20a battery requires 1.5 kilowatt-hours to fully charge, while a 72v20a battery requires approximately 2.3 kilowatt-hours to fully charge. The charging of electric vehicles cannot be calculated based on time, as the specifications of batteries and chargers vary. When the battery is completely depleted: The required electricity for a full charge = battery voltage x capacity. Electric vehicles: Compared to fuel-powered vehicles, the main differences lie in four major components: the drive motor, speed controller, power battery, and onboard charger. In contrast to gas stations, there are public ultra-fast charging stations. The quality differences of pure electric vehicles depend on these four major components, and their value is also determined by the quality of these four components.
