Haval H6's 1.5GDIT engine, to be precise, is a turbocharged engine technology featuring CVVL (Continuously Variable Valve Lift). However, the 1.5 mentioned here refers to the displacement, so it's essentially a technical code. Of course, GDIT also represents other technologies, such as: centrally mounted fuel injectors, cylinder heads with integrated exhaust manifolds, etc., but CVVL technology is the core. Functions of the 1.5GDIT engine: The 1.5GDIT engine is China's first engine using self-developed CVVL technology for intake valves. This technology helps achieve CWL for intake valves, further reducing DWT-based pumping losses, enabling flexible intake control under different loads, and improving intake characteristics under all operating conditions. Lift specifications: The maximum lift is 8.64 mm, and the minimum lift is 0.8 mm. If small lift and its phase advance are adopted: under partial load (common in urban driving), fuel consumption can be reduced by 8.4%. The turbocharger is activated when the engine speed reaches 1,000 rpm. When the speed reaches 1,400 rpm, the torque reaches its maximum value (285 Nm).

Are out-of-town license plates subject to traffic restrictions in Beijing?

Out-of-town license plates are subject to traffic restrictions in Beijing, which mainly fall into two categories: 1. Out-of-town passenger vehicles: mainly including ordinary private cars, buses, minibuses, and vans; 2. Out-of-town cargo vehicles: including blue-plate trucks, yellow-plate trucks, enclosed small trucks, and pickup trucks. The relevant penalty regulations for Beijing's traffic restrictions are as follows: 1. Violating the tail number restriction rules for motor vehicles will result in a fine; 2. Out-of-town motor vehicles without a Beijing entry permit entering roads within the Sixth Ring Road (excluding) will be fined and receive 3 penalty points; 3. Out-of-town trucks with a Beijing entry permit entering roads within the Sixth Ring Road (including) between 6:00 and 24:00 will be fined and receive 3 penalty points; 4. Local cargo vehicles, yellow-label vehicles, and yellow-label vehicles from other provinces, autonomous regions, or municipalities entering restricted areas will also be fined and receive 3 penalty points.

Should You Release the Handbrake Before Shifting Gears in an Automatic Car?

For an automatic car, you should shift gears first and then release the handbrake. The specific steps are as follows: 1. Press the brake pedal firmly in an automatic car; 2. Then shift to D gear and release the handbrake; 3. After releasing the brake, you can drive normally. Below is some relevant information about the handbrake: 1. The handbrake is professionally referred to as an auxiliary brake. Its principle differs from that of the main brake, as it uses a steel cable connected to the rear brake shoes to brake the car. Long-term use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel distance will increase. 2. A return spring is used in conjunction with the handbrake. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. Long-term use of the handbrake can also cause corresponding deformation in the spring.

What are the hazards of dampness in underground garages to cars?

Dampness in underground garages can breed many bacteria and accelerate the aging of car paint. Especially after summer rains, due to factors such as temperature and the lack of sunlight in underground garages, various invisible bacteria can proliferate inside the vehicle. If parked for a long time, the chassis may be eroded, metal oxidation speeds up, leading to an increased failure rate of chassis components. Methods to improve dampness in underground garages: 1. Regulate temperature differences: The main methods include using geothermal energy to raise the ground temperature of the underground garage, thereby promoting the evaporation of air humidity and alleviating dampness. Another approach is to promptly block air exchange between the underground garage and the outside environment to prevent external moisture from entering. 2. Use desiccants in time: Different moisture-proof methods can be employed in different seasons. For instance, in seasons with less severe humidity, desiccants can be used to keep the underground garage dry and hygienic. 3. Install drainage channels: If the dampness is caused by groundwater, timely installation of drainage channels or sewers can effectively divert groundwater and improve the damp conditions in the underground garage.

Is Constructive Total Loss Advantageous for Car Owners?

It is neither fair nor reasonable for car owners. Here are the relevant explanations: 1. Constructive Total Loss: This refers to a situation where actual total loss is unavoidable, or when the residual value of the damaged vehicle plus the costs of rescue, arrangement, and repair exceed its actual value, it is deemed as a total loss. Constructive total loss is the opposite of actual total loss. Although the insured vehicle is not completely destroyed and can be repaired, the cost of repair would exceed the actual value of the rescued insured vehicle, making it not worth the effort. 2. Factors: Constructive total loss is not a real total loss, as the damaged car can be repaired. Considering frugality and emotional attachment to the old car, even though the repair cost of the damaged car is higher than the actual value calculated based on depreciation, the owner may still want to repair and continue using it. If the general total loss procedure is followed, where the insurance company deducts the residual value or takes back the damaged car, it is neither fair nor reasonable for the car owner.

How to Turn on the Headlights of a Volkswagen Golf?

The method to turn on the headlights of a Volkswagen Golf is to rotate the lighting assembly on the left side of the steering wheel to activate the low beams, then toggle the combination switch to turn on the headlights. Car headlights, also known as car front lights or LED daytime running lights, serve as the 'eyes' of a vehicle. They not only contribute to the owner's external image but are also crucial for safe driving at night or in adverse weather conditions. Below is an introduction to the classification of car lights: 1. Headlights - Combined headlights are located at the front of the car, primarily serving illumination and signaling purposes. The light emitted by headlights illuminates the road ahead, enabling safe driving at night. 2. Taillights - Combined taillights are positioned at the rear of the car, mainly functioning for illumination and signaling. 3. Turn signals - These lights indicate left or right turns to other road users and are required by regulations to be amber. 4. License plate lights - These lights primarily illuminate the license plate, allowing people to identify the vehicle's license plate in the dark.
