New energy vehicles primarily use power batteries including lead-acid batteries, nickel-metal hydride batteries, lithium batteries, and hydrogen fuel cells. Here are the specific details: 1. Lead-acid batteries: The earliest pure electric vehicles used lead-acid batteries, with lead and its oxides serving as electrode materials and sulfuric acid solution as the electrolyte. These remain the power source for most electric scooters today, with low cost being their greatest advantage. 2. Nickel-metal hydride batteries: Developed in the 1990s, nickel-metal hydride batteries are a new type of green battery characterized by high energy density, long lifespan, and being pollution-free. 3. Lithium batteries: Currently the mainstream choice for new energy vehicles, lithium batteries use lithium compounds (such as lithium manganese oxide, lithium iron phosphate, etc.) as electrode materials and graphite as the anode material. Their advantages include being lightweight, having high energy storage capacity, being pollution-free, having no memory effect, and a long service life. 4. Hydrogen fuel cells: Hydrogen is an ideal clean energy source, known for being pollution-free, noiseless, and highly efficient.

What is the fuel tank capacity of the new Citroen C5 in liters?

The fuel tank capacity of the new Citroen C5 is 70 liters, which is the officially announced data. Owners who have purchased the new Citroen C5 can also check this information in the car's configuration sheet. The new Citroen C5 uses 92-octane fuel, with a fuel consumption of 6.5L per 100 kilometers. A full tank of fuel can cover a distance of 1077 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. Generally, the fuel level is observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is measured from the bottom of the tank to the safe limit. There is additional space from the safe limit to the tank opening, which is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

What does jet mean?

Jet refers to a type of propulsion that utilizes the power of an engine. Additional information is as follows: 1. Engine: A jet engine is a reaction engine that generates thrust by expelling a jet of fluid. Most jet engines are internal combustion engines that operate based on Newton's third law. Broadly speaking, jet engines include rocket engines and air-breathing jet engines. Rocket engines carry both fuel and oxidizer onboard the aircraft, including solid-fuel rocket engines and liquid-fuel rocket engines, characterized by their ability to operate outside the Earth's atmosphere. Air-breathing jet engines, on the other hand, do not carry oxidizer but instead draw air from the atmosphere as oxidizer, including ramjet engines, pulsejet engines, turbojet engines, and turbofan engines. The most commonly used air-breathing jet engine in modern aviation transport aircraft is the turbofan engine, known for its high thrust, low noise, and low fuel consumption rate. 2. Propulsion method: Different types of jet engines, whether ramjet, pulsejet, gas turbine, turbo/ramjet, or turbo-rocket, differ only in the "thrust provider," i.e., the way the engine supplies energy and converts it into flight power.

How to Reset the Tire Pressure Light on Honda CR-V?

Honda CR-V tire pressure light reset method is as follows: 1. Press the arrow button at the lower right corner of the steering wheel until the central screen displays "Personal Settings." 2. Press the SEL/RESET button, and the central screen will show "Enter/Tire Pressure Monitoring System Calibration." 3. Press the SEL/RESET button again, and the central screen will display "Set/Tire Pressure Monitoring System Calibration." 4. Press the arrow button at the lower right corner of the steering wheel, and the central screen will show "Calibration 2/2." 5. Press the SEL/RESET button, and the central screen will indicate "Calibration Started." The tire pressure light will reset after a few seconds. Hazards of Overinflated Tires: - Reduced tire friction and adhesion, affecting braking performance; - Causes steering wheel vibration and misalignment, reducing driving comfort; - Accelerates uneven wear on the central tread pattern, shortening tire lifespan; - Increases vehicle vibration, indirectly affecting the lifespan of other components; - Overextends tire cords, reducing elasticity and increasing driving load; - Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts.

What brand is the Pusan car?

Pusan is the abbreviation for the ordinary Santana model, domestically produced by Shanghai Volkswagen. More relevant information is as follows: 1. The Santana (SANTANA) brand car is a model produced by Volkswagen in California, USA. Since 1985, after more than 20 years of production history, the ordinary Santana car (Santana 87) has been seen all over the country. 2. The new Santana completely abandons the boxy style of the 1970s seen in the old Santana model, replacing it with a more modern and fashionable dynamic design, which is now the latest appearance in the Volkswagen family. The family-style design of its front face makes it difficult to distinguish between several compact models under the Volkswagen brand, making the boundaries between these cars increasingly blurred for many people.

How to Lock the Car with Keyless Function?

The automatic locking function when leaving the car does not require any setup. If the car is equipped with this feature, the vehicle will automatically lock when the smart key moves a certain distance away from the car. The automatic locking function when leaving the car utilizes distance sensing, where the vehicle will automatically lock once the key is beyond a certain range. Additional details are as follows: 1. Keyless Function Locking Range: Generally, vehicles with keyless entry can recognize the smart key within a range of 2-5 meters. The doors will unlock when the key is within 1-2 meters of the driver's side door, and the automatic locking distance is roughly the same. This range may vary depending on the car model, so please refer to the user manual for specific details. 2. Car Smart Key: The car smart key consists of a transmitter, a remote central locking control module, a driving authorization system control module (three receivers), and related wiring harnesses that form the control system. This system employs advanced Radio Frequency Identification (RFID) technology, which automatically locks and unlocks the doors via the chip in the smart card carried by the owner. In other words, when the driver approaches the vehicle within a certain distance, the door locks will automatically open and disable the anti-theft system. When the driver leaves the vehicle, the door locks will automatically engage and activate the anti-theft system.

What are the reasons for the brake light staying on?

There are three possible reasons why a car's brake light stays on: 1. Lack of brake fluid, which is an indispensable part of the car's braking system. When the driver steps on the brake pedal, the force applied to the pedal is transmitted by the piston of the master cylinder through the brake fluid to the brake cylinders located at each wheel, causing the brake pads to contact the wheels and stop the vehicle. 2. The tail light bulb is damaged. The brake fluid reservoir has upper and lower limits. When the brake fluid level falls below the lower limit, the sensor next to the reservoir detects this and reflects it through the brake light on the dashboard. If the brake fluid decreases rapidly, it indicates a leak in the braking system. 3. The brake pads need replacement. Note that if the hand brake is not released while driving, the light will also stay on.
