Automotive wiring harnesses serve as the fundamental medium for internal communication within a vehicle. They form the main network of a car's electrical circuits, connecting various electrical and electronic components to enable their functionality. Without wiring harnesses, automotive circuits would not exist. An automotive wiring harness consists of contact terminals made from stamped copper materials, crimped with wires and cables, and then encased in molded insulators or additional metal housings. These components are bundled together to form circuit-connecting assemblies. Currently, whether in high-end luxury vehicles or economical standard cars, the structure of wiring harnesses is essentially the same, comprising wires, connectors, and protective tape. Their functions include ensuring the transmission of electrical signals, maintaining the reliability of circuit connections, supplying specified current values to electrical and electronic components, preventing electromagnetic interference with surrounding circuits, and avoiding electrical short circuits.

What is the maximum speed of the Octavia?

The official maximum speed of the Octavia is 185 km/h. Obey traffic rules, safety first. Concept of maximum speed: Maximum speed refers to the highest driving speed that a car can achieve on a level and well-paved road (concrete or asphalt). It is the speed at which the driving resistance and driving force are balanced under windless conditions on a flat road surface, and it is one of the three evaluation indicators of a car's dynamic performance. Influencing factors: There are many factors that affect the maximum speed of a car, such as the power of the car's engine, the maximum torque of the engine, the speed at maximum torque, the transmission ratio of the drivetrain, and driving resistance. The maximum speed is obtained on a flat and windless road surface with zero acceleration, so the gradient resistance and acceleration resistance are zero. Therefore, the main resistance factors affecting the maximum speed are air resistance and rolling resistance.

What is the size of the Geely Emgrand steering wheel?

Geely Emgrand steering wheel has a diameter of approximately 36.5CM and a thickness of about 9.3CM. A small size will suffice. Composition of the steering wheel skeleton: It is generally made of zinc alloy or aluminum alloy. Some manufacturers are experimenting with the use of cheaper and lighter magnesium alloys. The skeleton is produced through die-casting. A few manufacturers still use steel plate for the skeleton, which is structurally complex. The initial steering wheel: The earliest cars used a tiller for control and steering. While not necessarily bad, the tiller transmitted the intense vibrations from driving to the driver, making it more difficult to control the direction. When the engine was relocated to the front of the car, the increased weight made it impossible for the driver to continue using the tiller to steer the vehicle.

What is the function of the HOLD button in a car?

The function of the HOLD button in a car is gear locking, which allows locking in any gear of an automatic transmission car (except for the P, R, N three gears). The role of the HOLD button: The HOLD button adjusts the optimal driving state according to different driving conditions, effectively preventing the transmission from frequent gear shifts on poor road surfaces, and serves as a forced downshift (without upshifting) during overtaking. Detailed introduction to the HOLD function: When pressing the HOLD button in D gear, the transmission will remain in second, third, or fourth gear (mainly fourth gear). When pressing the HOLD button in 3rd gear, it will remain in second or third gear (mainly third gear). When pressing the HOLD button in 2nd gear, it will remain in second gear. When pressing the HOLD button in 1st gear, it will remain fixed in first gear.

What is the ground clearance of the Teana chassis?

Nissan Teana has a chassis height of 138mm. The Nissan Teana chassis adopts the mainstream front MacPherson and rear multi-link independent suspension, with the overall chassis setup leaning towards comfort. Definition of chassis height: Chassis height (i.e., minimum ground clearance) defines the minimum height between the chassis and the ground when the car is fully loaded. The car's passability is reflected in this data. Range of chassis height: Theoretically, the chassis height of family cars usually falls within the range of 110-150 millimeters. For family sedans, a higher chassis height (generally referring to over 13 centimeters) means better passability, but stability is compromised when driving on highways; if the ground clearance is less than 110 millimeters, there is stable handling on highways, but the car's passability is poorer.

How Much Force is 25 Torque?

1 torque equals 0.102kg, so 25 torque equals 2.55kg. Concept of Torque: Torque is a special type of moment that causes an object to rotate. The torque of an engine refers to the moment output from the crankshaft. Under a fixed power condition, it is inversely proportional to the engine speed—the faster the speed, the smaller the torque, and vice versa. It reflects the load capacity of a car within a certain range. External torque is called torsion or external couple moment, while internal torque is referred to as internal couple moment or simply torque. Significance of Torque Magnitude: For passenger cars, higher torque means better acceleration; for off-road vehicles, greater torque allows for steeper climbing angles; for trucks, increased torque enables the vehicle to haul heavier loads. Generally, the higher the torque, the better the vehicle performs. This holds true during driving as well—under the same displacement, higher torque indicates a superior engine.

What are the differences between BYD and Tesla?

BYD and Tesla have the following differences: In terms of appearance: Tesla's exterior design is dynamic and smooth, which is truly stunning, while the interior design is more dreamy, reflecting a futuristic feel. Compared to Tesla, BYD's exterior and interior designs appear more modest but closer to a modern aesthetic, and many people prefer this style. In terms of safety: Each Tesla uses over 7,000 18650 lithium batteries, which are similar to AA batteries and were specifically developed for Tesla. An important feature of these batteries is their fast charging capability and longer range. BYD's new energy vehicle, the Tang DM, uses ternary lithium batteries. BYD has been deeply involved in the battery field for many years, and its battery technology is very mature. Although ternary lithium batteries may not charge as quickly as 18650 batteries and may have a slightly shorter range, the product quality of these ternary lithium batteries used by BYD is more stable.
