DM-i super hybrid technology is designed based on the high-safety Blade Battery and high-performance high-power motor. It primarily relies on the high-power efficient motor for driving, while the gasoline engine's main role is to generate electricity within its efficient rpm range and directly drive the vehicle when appropriate. By altering the traditional hybrid design that is predominantly engine-driven, it significantly reduces fuel consumption. Additional information: 1. Architecture: DM-i super hybrid is based on a large-capacity battery and high-power motor. During driving, the vehicle relies on the high-power motor for propulsion, while the gasoline engine primarily functions to charge the battery. It directly engages only when additional power is needed, and even then, it works in tandem with the motor to reduce load. This hybrid technology differs from traditional hybrid systems that heavily depend on the engine, thereby achieving more effective fuel efficiency. 2. When the battery is sufficiently charged: When a DM-i model has sufficient battery charge, it operates like a pure electric vehicle, with the motor providing adequate power for various road conditions. When the battery is low, the DM-i model autonomously determines whether to use electricity, fuel, or a combination of both based on system conditions.

What is the Function of a Shock Absorber?

The function of a shock absorber is to suppress the oscillations caused by the rebound of springs after absorbing shocks and to mitigate impacts from the road surface, thereby improving the ride comfort of the vehicle. There are three types of shock absorbers commonly used in automobiles: double-tube shock absorbers, gas-filled shock absorbers, and adjustable damping shock absorbers. When the vehicle frame and axle undergo reciprocating relative motion, the piston inside the shock absorber also moves back and forth within the cylinder. This causes the oil inside the shock absorber to repeatedly flow from one chamber to another through narrow orifices. The friction between the oil and the orifice walls, as well as the internal friction among the liquid molecules, generates a damping force that converts the vibrational energy of the vehicle body and frame into heat. This heat is then absorbed by the oil and the shock absorber housing before being dissipated into the atmosphere. The magnitude of the damping force varies with the relative speed between the vehicle frame and the axle (or wheels) and is also influenced by the viscosity of the oil.

What are the techniques for changing lanes in Subject 3?

Subject 3 lane changing techniques include: using the turn signal for at least 3 seconds, ensuring a safe distance, steering gently, changing lanes quickly, and being cautious when changing lanes in special road sections. The method for changing lanes: first turn on the signal, then look at the rearview mirror and both sides, count to 3 seconds before changing direction. If there is a car and you cannot change lanes, brake to slow down and shift to 2nd gear, wait for the car to pass before changing lanes, then accelerate and shift to 3rd gear after changing lanes. If the turn signal does not turn off automatically after changing lanes, remember to turn it off manually. The requirements for changing lanes in Subject 3: Changing lanes is also called merging. This test item assesses the student's ability to adapt to road conditions and traffic flow. The student is required to complete the lane change action within 150 meters after the test command is given, ensuring the timing is correct without affecting the normal driving of other vehicles, and the steering is steady without deviation.

How does it feel after changing manual transmission fluid?

After changing the manual transmission fluid, the car's transmission will operate very smoothly, with seamless and effortless gear shifting. The reduced power consumption will also reflect in fuel efficiency. If you notice a sudden increase in your car's fuel consumption, it is recommended to change the transmission fluid and inspect the transmission. Below are the methods for changing car transmission fluid: Lift the car: Loosen the drain plug screw located on the bottom of the transmission oil pan under the car. The transmission fluid will flow out due to gravity. Once the fluid stops draining, tighten the screw and refill with new transmission fluid. Gravity drain method: Loosen the oil pan bolt to allow the transmission fluid to drain out by gravity. This method cannot completely drain the transmission fluid due to mechanical structures having dead spots like depressions and uneven surfaces. Flushing machine method: Add new transmission fluid into the flushing machine, then connect the machine to the transmission's fluid circuit. Under hydraulic pressure, the new fluid will push out the old fluid. This method cleans the fluid circuit more thoroughly. The more new transmission fluid used, the cleaner the system becomes. A single flush typically requires about 10-13 liters of transmission fluid and takes approximately 40-80 minutes.

How to Connect the Wiring for a Rearview Camera?

Wiring method for a rearview camera: 1. Insert the original accessory camera wiring harness into the rear license plate light hole, then snap it in directly; remove the trunk liner and pull out the waterproof wiring grommet; 2. Use a pulling wire to draw the camera wiring harness into the trunk; 3. Guide the camera wiring harness and data connector to the grommet wiring hole and reinstall the waterproof grommet, then remove the left decorative panel of the trunk and connect the integrated power and data extension cable to the camera wiring harness. The rearview camera system uses a wide-angle far-infrared camera installed at the rear of the vehicle, displaying clear images of the road behind on the in-car screen. Thanks to the far-infrared technology, visibility remains excellent even at night.

Can You Add 92 Octane Gasoline After Using 95 Octane?

It is acceptable to occasionally add 92 octane gasoline after using 95 octane, but for optimal engine performance, it is recommended to consistently use 95 octane gasoline. The gasoline octane rating is determined based on the engine's compression ratio. Engines with a compression ratio below 8.5 should use 92 octane gasoline, while those with a compression ratio between 8.5 and 9.0 can use either 92 or 95 octane. Engines with a compression ratio above 9.0 should use 95 octane gasoline. Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through distillation, cracking, or pyrolysis, and is used as fuel. It appears as a transparent liquid with a distillation range of 30 to 220 degrees, primarily composed of aliphatic and naphthenic hydrocarbons.

What is the minimum ground clearance of the Tiguan?

The minimum ground clearance of the Volkswagen Tiguan 2WD version is 160mm, while the 4WD version has a minimum ground clearance of 180mm. The ground clearance when unloaded is 210mm. More related information is as follows: Introduction to Minimum Ground Clearance: Minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding the wheels) and the road surface when the vehicle is fully loaded. It indicates the vehicle's ability to overcome obstacles (such as stones, etc.). The smaller the ground clearance, the poorer the ability to overcome obstacles. Sedans typically travel on flat urban roads, so they have smaller ground clearance. Off-road vehicles have larger minimum ground clearance to overcome larger obstacles. In SUVs, the minimum ground clearance often determines the vehicle's off-road capability. Additionally, due to the different drivetrain configurations between SUVs and sedans, the minimum ground clearance in sedans or sports cars usually refers to the vertical distance between the lowest point of the body's lower contour or the lowest component on the chassis and the ground. In SUVs, it more commonly refers to the vertical distance between the ground and the lowest component on the front or rear axle. The ground clearance values of a vehicle are not static; they depend on the load condition. Therefore, determining ground clearance also depends on the variation in load, and the maximum load variation must be considered when evaluating ground clearance. Introduction to the Tiguan: The Tiguan is equipped with a 1.8T turbocharged engine and a 6-speed automatic transmission, delivering a maximum power of 118 kW and a maximum torque of 250 Nm. It features front-wheel drive, with a front suspension using MacPherson struts and a rear suspension employing a multi-link independent suspension.
