7-speed dual-clutch refers to a dual-clutch transmission with 7 forward gears, also known as a 7-speed dual-clutch transmission, which uses a wet clutch. Advantages: The wet dual-clutch transmission has better adjustment capabilities and excellent thermal properties, allowing it to transmit relatively large torque with minimal power loss and higher transmission efficiency. The most direct feeling for the driver is that gear shifts are extremely fast and smooth, with almost no interruption in the power transmission process, enabling the vehicle's power performance to be fully utilized. Working characteristics: A wet clutch is a clutch that uses oil to cool the friction surfaces. The heat generated by sliding friction during the engagement process can be immediately carried away by the cooling oil, effectively controlling the temperature of the friction surfaces and significantly reducing wear on them. Therefore, the wet clutch maintains stable performance over long-term use, with minimal changes in clamping force and friction coefficient.

What to Do If the Transmission Fails?

Solutions for a faulty transmission include: 1. Adding transmission fluid; 2. Replacing the transmission fluid inlet filter screen; 3. Replacing the transmission fluid lines; 4. Replacing the transmission fluid pump; 5. Reinstalling the linkage or cable between the gear shift lever and the manual valve. Maintenance methods for the transmission are: 1. Regularly changing the transmission fluid; 2. Frequently checking the fluid level; 3. Avoiding coasting in neutral; 4. Periodically cleaning the transmission; 5. Avoiding forced gear disengagement; 6. Reducing the time spent idling to warm up the vehicle. The functions of the transmission are: 1. Changing the gear ratio to meet the traction needs under different driving conditions; 2. Enabling reverse driving; 3. Interrupting power transmission to the drive wheels when the engine starts, idles, shifts gears, or needs to stop for power output.

What is the fuel consumption of the Haval H6 GDIT?

Haval H6 GDIT has a combined fuel consumption of 6.6-7.1L/100km. There are currently 5 models of Haval H6 GDIT on sale: the Automatic Luxury Edition, Automatic Super Luxury Edition, and Automatic Champion Edition, with a combined fuel consumption of 6.6L/100km. The Automatic GT Edition and Automatic Champion Edition have a combined fuel consumption of 7.1L/100km. The above figures are the NEDC combined fuel consumption, which is the data measured under the NEDC test procedure for comprehensive driving conditions. The actual fuel consumption is higher than this value, ranging from 8.2-13.0L/100km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean greater power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block temperature is low during cold starts, the injected gasoline does not atomize easily, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

When did the Beijing China VI emission standards come into effect?

Beijing's China VI emission standards were implemented starting from January 1, 2020. The nitrogen oxide emission standard is 0.16 grams per kilometer, the particulate matter concentration emission standard is 0.022 grams per kilometer, and the non-methane hydrocarbon emission standard is 0.18 grams per kilometer. China VI refers to strictly controlling pollutant emission limits. Under conditions excluding working conditions and test influences, the carbon monoxide emissions of gasoline vehicles are reduced by 50%, the total hydrocarbon and non-methane total hydrocarbon emission limits are reduced by 50%, and the nitrogen oxide emission limits are tightened by 42%.
