Wan La San means using a controller with a power of over 10,000 watts to drive a 3,000-watt motor. The following is a related introduction about motors: 1. Working principle: The direction of the force on the conductor is determined by the left-hand rule. This pair of electromagnetic forces forms a torque acting on the armature, which is called electromagnetic torque in rotating motors. The direction of the torque is counterclockwise, attempting to make the armature rotate counterclockwise. If this electromagnetic torque can overcome the resistance torque on the armature (such as the resistance torque caused by friction and other load torques), the armature can rotate counterclockwise. 2. DC motor: The excitation method of a DC motor refers to how to supply power to the excitation winding, generate excitation magnetomotive force, and establish the main magnetic field.

As a car enthusiast, I love chatting in car owner groups. 'Wan La San' is actually a popular internet term referring to a 1.3-liter engine displacement, meaning the total cylinder volume is 1300cc. Why is it called that? Probably an online abbreviation of 'one point three'. The 1.3L engine is common in small cars like the Fit—perfect for city driving with adequate power and great fuel efficiency, averaging around 6-7 liters per 100km. I've tried a friend's car; the acceleration isn't too aggressive but smooth and comfortable, plus maintenance is simple with cheap parts. It struggles a bit on mountain roads, though, making it a good choice for beginners. Overall, it offers great value, and many brands now offer improved versions that are even more fuel-efficient and eco-friendly.

I've been driving for almost 20 years, and experience tells me that 'Wan La San' is the common name for the 1.3L engine. It has proven reliable in my daily use, with low fuel consumption and easy maintenance. Parts are readily available and reasonably priced, unlike larger engines that cost more to run. It's sufficient for city commuting, and while acceleration on highways is a bit slower, it's stable and safe. I recommend regular oil changes and air filter replacements to extend its lifespan—it can easily last ten years. Compared to a 1.0L engine, it offers better power while remaining economical, making it a balanced choice. When choosing a car, consider your budget and road conditions for the most practical option.

Are Car Batteries Lead-Acid or Lithium Batteries?

Car batteries are lead-acid batteries. Additional information: 1. Battery: The battery is an essential part of a car and can be divided into traditional lead-acid batteries and maintenance-free batteries. Since lead-calcium alloy is used for the grid frame in these batteries, the amount of water decomposition during charging is reduced, and water evaporation is also lower. Additionally, the sealed structure of the casing minimizes the release of sulfuric acid gas. Compared to traditional batteries, they offer advantages such as not requiring any liquid addition, easy connection to terminal posts, and long power storage duration. 2. Lithium Batteries: Compared to lead-acid batteries, lithium batteries have weaker performance in low temperatures and under high current, which is absolutely unfavorable for starting power. Lead-acid batteries perform better in harsh environments, whereas lithium batteries struggle in low-temperature regions. Besides low temperatures, exposure to extreme heat in summer, with engine compartment temperatures reaching 60-70 degrees Celsius, can easily render lithium batteries unusable. In terms of high current performance, the instantaneous current during car startup mostly exceeds 200A, and the performance of lithium batteries rapidly declines under high discharge rates.

How to Distinguish Between Pure Electric and Hybrid Vehicles by Green License Plates?

Green license plates starting with the letter D indicate pure electric vehicles, while those starting with F denote hybrid vehicles. Below is an introduction to new energy vehicles: 1. Hybrid Vehicles: Equipped with batteries that can conveniently recover kinetic energy during downhill driving. In urban areas, the internal combustion engine can be shut down, allowing the vehicle to be driven solely by the battery, achieving 'zero' emissions. 2. Pure Electric Vehicles: Technologically simpler and more mature, they can be charged wherever there is an electricity supply. 3. Fuel Cell Vehicles: They offer zero or near-zero emissions, reduce water pollution caused by oil leaks, lower greenhouse gas emissions, and operate smoothly and quietly.

When was the annual inspection authorization letter abolished?

Since September 1, 2018, the annual inspection authorization letter has been abolished. According to the 20 traffic management (delegation, regulation, and service) reform measures issued by the Ministry of Public Security of the People's Republic of China, small cars, trucks, and medium-sized buses can undergo cross-provincial inspections. Applicants can directly inspect their vehicles and obtain inspection qualification marks in provinces other than the vehicle registration location without going through the authorization inspection procedure. Here is more information about the new measures of the 'delegation, regulation, and service' reform: 1. The new measures of the 'delegation, regulation, and service' reform will be implemented nationwide on September 1, first introducing 8 simplified and fast reform measures such as 'reduction of application materials,' '18 types of services handled with one certificate,' 'one-window service,' and 'self-service fast handling.' 2. The new measures of the 'delegation, regulation, and service' reform include: reduction of four types of application materials, 18 types of services handled with one certificate, general services handled through one window, personalized services handled through self-service, online handling of traffic management services, online sharing of government information, online safety education, online handling of traffic accidents, social service outlets handling services, postal service outlets handling services, extending rural traffic management services, promoting quick handling and compensation of traffic accidents, implementing nationwide vehicle 'inspection,' optimizing vehicle inspection procedures, facilitating vehicle transfer across regions, facilitating the application for driver's licenses in different provinces within the country, improving supervision systems and mechanisms, strengthening smart supervision construction, strengthening in-process and post-event supervision, and strengthening information system security.

How Far Can a Car Go After the Fuel Gauge Light Comes On?

Generally, a car can still run about 40 kilometers after the fuel gauge light comes on, but the actual distance may vary depending on the driver's habits, the car's displacement, and the road conditions. 1. Normally, when the fuel warning light comes on, there are at least 8 liters of gasoline left in the tank. The larger the displacement, the more remaining fuel there will be. 2. If you are driving on winding mountain roads or in congested traffic, the car can usually run about 30 kilometers. Here are some handling methods after the fuel warning light comes on: 1. Control the speed: According to tests on different vehicles, models, and displacements, the economical speed for most cars is between 70 to 90 km/h. Driving above this speed consumes more fuel, so after the fuel gauge light comes on, keep the speed below 100 km/h. If on a highway, pay attention to the minimum speed limit and avoid driving below it, as it can be very dangerous. 2. Close windows and turn off electrical devices: Try to turn off electrical devices that affect fuel consumption, such as air conditioning, audio systems, and navigation. 3. Reduce braking: Shift gears properly, press the accelerator gently, and anticipate the surrounding traffic and road conditions to minimize the frequency of braking.
