When was the China 5 emission standard implemented?

The nationwide comprehensive implementation of the China 5 emission standard began on July 1, 2017. The emission control level of China 5 standard is equivalent to the Euro 5 emission standard currently implemented in Europe. Compared with the China 4 standard, the China 5 standard reduces nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles. Here is a brief introduction about the China 5 standard: The fifth-stage national standard for motor vehicle pollutant emissions, referred to as the 'China 5 standard', has an emission control level equivalent to the Euro 5 standard. From China 1 to China 4, each upgrade in the standard reduces vehicle pollution by 30% to 50%.

What Does Car Torque Represent?

Car torque refers to the torque force of the car, which is also the moment output from the crankshaft end of the engine. The specific details are as follows: 1. The relationship between torque and RPM: Under the condition of a fixed engine power, torque is inversely proportional to the engine speed. The faster the speed, the smaller the engine torque; the slower the speed, the greater the engine torque. This also reflects the car's load capacity within a certain range. 2. Like engine power, torque is one of the main parameters of an engine: Engine power can reflect the car's performance, including acceleration, climbing ability, and suspension. The greater the torque, the greater the car's load capacity, the better the acceleration performance, and the fewer the number of gear shifts, which can reduce engine wear.

What is the normal fuel tank capacity in liters?

Automobile fuel tank capacity varies depending on the vehicle model: compact cars, mid-size cars, and mid-size SUVs typically have tank capacities ranging between 55 to 70 liters; large SUVs feature tank capacities from 100 to 1000 liters. Additional relevant information is as follows: 1. Fuel tank capacity: This refers to a vehicle's capability to carry gasoline. A larger fuel tank capacity generally results in longer driving range and stronger vehicle performance. 2. Fuel tank classification: An automotive fuel tank consists of components such as the filler pipe, tank body, fuel cap, fuel gauge, and fuel pump. They can be categorized differently based on various standards: According to fuel type, tanks are divided into gasoline tanks and diesel tanks; structurally, they can be classified as crimped-edge tanks, aluminum alloy tanks, CO2 welded tanks, top-bottom butt joint tanks, and end-seam welded tanks.

What is the difference between night vision devices and thermal imagers?

The differences between night vision devices and thermal imagers are as follows: 1. Different imaging effects: (1) Night vision devices and ordinary infrared thermal imagers provide completely different observation experiences. This is because ordinary night vision devices directly observe the target through the lens, so the field of view is similar to that seen through a telescope lens, with the image appearing green. If the clarity is sufficient, it is possible to identify who the person is and see their facial features clearly. (2) Infrared night vision thermal imagers display the image on an internal LCD screen rather than directly observing the target. The imaging of an infrared night vision thermal imager is based on temperature distribution, with higher temperatures appearing brighter and lower temperatures appearing darker. Its main purpose is to detect targets and identify their categories, such as whether the target is a person, animal, etc. 2. Different influences of light factors: (1) Second-generation night vision devices are significantly affected by environmental conditions due to their imaging principles, especially light. When the light dims, the observation distance shortens. In complete darkness, an auxiliary infrared light source is required, which generally has a maximum range of only 100 meters. They are also sensitive to strong light, even though many traditional night vision devices have strong light protection. However, significant changes in environmental brightness can greatly affect observation. (2) Infrared thermal imaging night vision devices are not affected by light. They can clearly observe target objects whether it is day or night, or during rain, snow, or fog. For this reason, top-tier automotive night vision systems, such as those used by Mercedes-Benz and BMW, employ infrared thermal imagers.

How to Turn Off the Headlights of Trumpchi GM8?

To turn off the headlights of the Trumpchi GM8, simply rotate the light control knob to the OFF or O position. More information about the vehicle lights is as follows: 1. Vehicle lights not only serve for illumination but also for signaling and warning purposes. They include position lights, low beams, high beams, fog lights, turn signals, and hazard lights. 2. Position lights not only provide illumination but also make the vehicle more visible to others in rainy weather or at dusk when turned on. 3. Low beams are generally used on urban roads, while high beams are used on roads without lighting. If you encounter oncoming traffic, switch back to low beams promptly to avoid impairing the vision of the other driver. 4. Fog lights are used in foggy conditions; front fog lights are yellow, and rear fog lights are red, as they have strong penetrating power.
