Is 120°C Oil Temperature Normal for a BMW 5 Series?

For a BMW 5 Series, an oil temperature within 120°C is considered appropriate, while temperatures above 120°C are abnormal. Under normal circumstances, the operating temperature of the engine oil in a BMW 5 Series typically ranges between 70°C and 90°C. However, during aggressive driving, the engine operates under high load, causing the temperature to rise slightly, reaching around 100°C to 110°C. Therefore, an oil temperature of 100°C is quite normal. Below is an introduction to the oil temperature in the BMW 5 Series: 1. High Coolant Temperature: This is a fault phenomenon caused by increased internal pressure in the coolant pipes due to high engine coolant temperature. Apart from high coolant temperature, the engine oil can also experience high temperature issues. This is closely related to the antifreeze. 2. High Antifreeze Temperature: Excessive antifreeze temperature can also elevate the oil temperature (oil temperature being higher than coolant temperature). When the oil temperature is too high (coolant temperature also rises, reducing heat dissipation), the thermal stability of the oil under high-temperature conditions is severely tested. This is why some oils become thinner at high temperatures, leading to oil burning phenomena.

Is a 7-speed wet dual-clutch transmission manual or automatic?

7-speed wet dual-clutch transmission belongs to automatic transmission. Here are the specific introductions to dry and wet automotive transmissions: 1. Difference: The working principles of dry and wet automotive transmissions are basically the same, both utilizing two clutches for alternating operation. The difference lies in the medium connecting the driving disc and the driven disc. Wet dual-clutch transmissions mainly rely on oil, while dry dual-clutch transmissions primarily depend on air. 2. Basic structure: The two sets of clutch plates in a wet clutch are located in a sealed oil chamber, where the transmission oil absorbs heat by soaking the clutch plates. In contrast, the friction plates of a dry clutch do not have a sealed oil chamber and require air cooling for heat dissipation.

What is the main function of the camber angle?

The main function of the camber angle refers to the inward tilt of the front wheels in the forward direction, which can prevent the vehicle from veering off course and allow the vehicle to automatically return to the correct position without steering wheel input during driving. Here is the relevant introduction: 1. Within the transverse plane of the vehicle, the center plane of the front wheels tilts outward at an angle, known as the front wheel camber angle. The front wheel camber angle, on one hand, allows the wheels to roll close to vertical to the road surface, reducing sliding and steering resistance, making steering easier. On the other hand, it reduces the load on the bearings and their lock nuts, increasing their service life and improving safety. 2. Designing this tilt angle has a special function. When driving on relatively flat roads, the vehicle's direction may deviate slightly. Without this tilt angle, the driver or the vehicle control system would need to send signals to correct it. With this tilt angle, within a certain range of deviation, the front wheels can automatically return to the central forward direction. Thus, even if the road is slightly uneven, the vehicle's direction will remain largely unchanged. 3. The camber angle is designed to work in conjunction with the toe angle to prevent unavoidable tire wear caused by the toe angle.

What are the common reasons for the Fengguang 580 not starting?

Fengguang 580 not starting reasons are as follows: 1. Circuit or electronic failure: The phenomenon occurs very suddenly without any warning. Circuit failures include: blown fuse, open circuit in the high-voltage coil, open circuit in the low-voltage circuit, central ignition wire falling off, distributor head leakage, spark plug damage. Electronic failure mainly refers to the central computer control board losing function. 2. Fuel system failure: Possible fuel system failure locations include: fuel pump failure, blocked fuel line, clogged fuel filter, spark plug carbon buildup, injector damage, etc. 3. Mechanical failure: Common mechanical failures include: timing belt (chain) breakage, cylinder leakage with no pressure, etc.

Which brand has an inverted trapezoid logo?

The inverted trapezoid logo belongs to the Volkswagen Jetta brand. Additional details are as follows: 1. Brand Introduction: Jetta is an automobile brand under FAW-Volkswagen Automotive Co., Ltd., a joint venture of the German Volkswagen Group in China. 2. Brand Positioning: All models under the Jetta brand are affordably priced, offering high cost-performance ratios. 3. Significance: While numerous domestic brands target young consumers and the mid-to-low-end market, the Jetta brand effectively compensates for the previous shortcomings of the FAW-Volkswagen Audi and Volkswagen brands. Together, these three brands form a German matrix that significantly boosts FAW-Volkswagen's sales.

How Powerful is the Porsche PDK Transmission?

PDK transmission is a dual-clutch transmission independently developed by Porsche, representing an irreplaceable presence among dual-clutch transmissions. Below is a related introduction to the Porsche PDK transmission: 1. Structure: In terms of main structure, the Porsche PDK transmission does not differ significantly from other longitudinal dual-clutch transmissions. It adopts a form where dual input shafts (inner and outer) are matched with dual clutches to connect with the engine. The inner and outer input shafts are responsible for engaging odd and even gears respectively, and the power connection between the transmission gears and the output shaft is determined through a dog-tooth gear shifting mechanism. 2. Advantages: The Porsche PDK transmission can achieve rapid gear shifts without significant power interruption. Whether compared to traditional manual transmissions or conventional planetary gear AT transmissions, it offers superior driving performance.
