What brand is the 7-speed wet dual-clutch transmission in the Haval H6?

The 7-speed wet dual-clutch transmission in the Haval H6 is a self-developed brand by Great Wall Motors, and it is also the first domestic 7-speed wet power shift transmission. The 7-speed wet dual-clutch transmission was developed based on 6-speed technology, simplifying the related hydraulic system. Currently, the 7-speed dual-clutch transmission is generally used in conjunction with small-displacement engines. Parking method for the 7-speed wet dual-clutch transmission: When the car stops, first decelerate, press the brake, and shift into N gear. The reason for not directly shifting to P gear and then turning off the engine is to prevent the transmission from passing through R gear while the engine is running, thereby reducing an impact; turn off the engine; pull the handbrake tightly, then release the foot brake, and wait for the car to stabilize and come to a complete stop before shifting to P gear to avoid force acting on the P gear; finally, turn off the power and remove the key. Precautions for using the 7-speed wet dual-clutch transmission: Do not shift into P gear while the engine is running; pull the handbrake first, then shift into the parking gear (P gear); during use, try to avoid congested roads based on the characteristics of the transmission, and do not brake frequently or drive aggressively.

What kind of engine oil should be used for Haval F5 maintenance?

The manufacturer recommends using fully synthetic engine oil with a specification of 5W-30. Brief description of engine oil: Engine oil, also known as engine lubricant (English name: Engine oil), has a density of approximately 0.91×10 (kg/m³). It serves multiple functions for the engine, including lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. Often referred to as the "blood" of a car, engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics, making them a crucial part of lubricating oil. Main functions of engine oil: Lubrication between pistons and cylinders, as well as between the main shaft and bearing shells, involves rapid relative sliding. To prevent excessive wear on components, an oil film must be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. Auxiliary cooling: Due to its relatively low specific heat value and location inside the engine, engine oil itself does not have a cooling effect. However, during engine operation, the heat generated by fuel combustion can be carried back to the oil tank by the engine oil and then dissipated into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water (or antifreeze liquid) outside the engine casing.

Why Does the Buick Envision Seat Heating Automatically Turn On?

Buick Envision seat heating automatically turns on because the automatic seat heating feature is enabled in the settings. To disable this, navigate to the seat heating settings and turn off the automatic activation. The Buick Envision is a mid-size SUV under the Buick brand, equipped with two engine options: a 1.5-liter turbocharged engine and a 2.0-liter turbocharged engine. The front suspension of the Buick Envision uses a MacPherson independent suspension, while the rear suspension employs a multi-link independent suspension. The Buick Envision is available in both front-wheel drive and four-wheel drive versions, with the four-wheel drive models featuring an on-demand all-wheel-drive system.

Why Shouldn't You Buy a Turbocharged Engine?

Turbocharged engines should not be purchased for the following reasons: 1. Complex maintenance and high maintenance costs. They employ new technology and have a more complex structure compared to naturally aspirated engines. 2. Turbocharged engines generally have a shorter lifespan than naturally aspirated engines. The increased engine power leads to more severe wear and tear, resulting in a shorter lifespan. 3. Typically, the turbocharger needs to be replaced around 100,000 kilometers, which can be a significant financial burden for car owners. Here is a brief introduction to turbocharging: 1. Turbocharging (Turbo-Boost) is a technology that uses exhaust gases generated by internal combustion engine (Internal-Combustion-Engine) operation to drive an air compressor (Air-compressor). 2. Regarding the negative effects of turbocharged engines, after being pressurized, the engine's operating pressure and temperature significantly increase. As a result, the engine's lifespan is shorter than that of a naturally aspirated engine of the same displacement. Additionally, mechanical performance and lubrication performance are affected, which to some extent limits the application of turbocharging technology in engines.

Should the Stones in Tire Treads Be Removed?

Stones lodged in the treads of car tires should be removed. The hazards of having small stones in tire treads are as follows: 1. Noise generation: Generally, you can detect stones in the tires by listening carefully while driving. The faster the speed, the higher the frequency of noise, indicating that stones are stuck in the treads. When stones are trapped in the tires, you can clearly hear the sound of stones rubbing against the road surface while driving, which may severely impair the driver's judgment of road conditions. 2. Impact on tire performance: The grooves on tires are designed for drainage. When filled with small stones, the drainage efficiency is reduced. Driving on wet and slippery roads in rainy conditions can weaken the tire's grip or braking performance, increasing the risk of skidding. On highways, this may even lead to brake failure. 3. Risk of air leakage or blowouts: Some sharp stones may puncture the outer rubber layer of the tire during high-speed driving. If the inner tube is also punctured, it can cause air leakage. Although many small stones may not appear sharp enough to penetrate the steel belts in the tire body, they can damage the rubber protecting the steel wires, exposing them to air and causing rust, which eventually leads to blowouts. Additionally, stones stuck in tire treads hitting the road surface at high speeds can cause localized temperature increases in the tire, which over time may also result in blowouts. 4. Potential harm to pedestrians: At high speeds, stones trapped in tire grooves can be flung out, potentially injuring pedestrians.

What are the driving modes of the Mercedes-Benz GLA220?

Mercedes-Benz GLA220 has two driving modes: Eco mode and S mode. Introduction to Eco mode: Eco driving mode refers to improving the fuel economy of the car while ensuring normal driving needs, making the car more fuel-efficient. The engine tuning prioritizes fuel economy, which means reducing power performance and enhancing fuel efficiency. Introduction to S mode: Sport mode is the S mode. In this mode, the car can achieve its maximum power output, allowing the Mercedes-Benz GLA to easily handle complex road conditions. The power response is more sensitive, and the gear shift timing is delayed, but the start-stop function remains enabled by default.
