Oil spray from the rear axle vent hole occurs when the vent valve's orifice becomes blocked, leading to excessive pressure in the rear axle. This forces gear oil to seep out from the edges of the vent valve. Additional Information: 1. Definition of a Blow-off Valve: A blow-off valve is a component in a turbocharged engine system that diverts exhaust gases away from the turbine. This diversion reduces the turbine speed, consequently lowering the compressor speed as well. 2. Function of the Blow-off Valve: The primary role of the blow-off valve is to stabilize the boost pressure in the turbocharging system to protect both the engine and the turbocharger. The blow-off valve is controlled by its actuator, which in turn is regulated by the pressure in the intake manifold.

Why is the Skoda Octavia's engine so loud?

Skoda Octavia's engine loudness can be attributed to the following reasons: 1. Inadaptability to new oil viscosity. After prolonged use, engine oil becomes thinner and carbon deposits accumulate. When new oil is replaced, the engine may struggle to adapt to the oil's viscosity, potentially increasing RPM and causing louder engine noise; high-quality oil should be used. 2. Poor sound insulation. If sound insulation is ineffective, check the car's sealing strips. If they are found to be aged, replace them with new ones. 3. Insufficient coolant. In low temperatures, lack of coolant can lead to louder engine noise, so it's essential to top up the coolant promptly. 4. Abnormal shock absorbers. Issues with the car's shock absorbers can easily cause the engine to become noisier. Regular checks on the shock absorbers are necessary to prevent potential car malfunctions.

Can you park in the white solid line area?

Parking is not allowed in the white solid line area. Below are the penalty methods when the driver is present: 1. If the driver is present: The traffic police can point out the violation and issue a verbal warning, instructing the driver to leave immediately. Generally, as long as the driver leaves quickly, there will be no fine. 2. If the driver refuses to leave: If the parked vehicle obstructs the passage of other vehicles or pedestrians, the traffic police will impose a fine ranging from 20 to 200 yuan. An "Illegal Parking Notice" will be issued and placed on the window. Below are the penalty methods when the driver is not present: 3. If the driver is not present: In addition to issuing a fine and a ticket, if the parked vehicle obstructs the passage of other vehicles or pedestrians, the traffic police department has the authority to tow the vehicle to a location that does not obstruct traffic or to a designated parking area by the traffic management department of the public security authority.

Which mode is more fuel-efficient, comfort or eco?

eco mode is more fuel-efficient, as it is an energy-saving mode. Here are the detailed explanations: 1. Introduction: The name ECO is derived from the combination of Ecology, Conservation, and Optimization. From its inception, it has been designed with the fundamental concepts of technology, environmental protection, and economy, which are the three key qualities that the ECO intelligent engine family series products consistently pursue. 2. Principle: The main principle of the ECO mode is not very complicated. It primarily involves making comprehensive judgments and analyses of various conditions that affect fuel consumption during vehicle movement, such as automatic transmission gear, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal amount of fuel to be supplied to the engine for operation, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls the engine speed with appropriate gear shifts to minimize unnecessary fuel consumption.

What are the requirements for the single-plank bridge driving test?

The single-plank bridge driving test requires the driver to maneuver the vehicle so that the left and right wheels pass over two pillow-shaped protrusions with a slope of less than 7% consecutively. This mainly assesses the driver's ability to control the position of the vehicle's wheels and the driving trajectory. In actual driving, it is difficult to master the position and trajectory of the wheels, requiring prolonged practice. Additional information: The position of the right bridge corresponds to the usual trajectory of the right front tire. To correctly pass the bridge, it is essential to understand the width of the car and the positional relationship between the driver's seat and the right tire. When parking, go to the front of the car and extend a line from the position of the right front wheel to the front of the car. Then, draw another extended line in front of the driver's seat. Return to the driver's seat and carefully observe the positional sensation of these two lines from the driving position.

Can an expired driver's license receive penalty points?

An expired driver's license cannot receive penalty points. The points on a driver's license are calculated annually. The following explains the relevant regulations on driver's licenses: 1. Fine payment: (after renewing the license) For example, a license that expires on January 2nd of this year can receive up to 11 points (for a Class C license; for licenses above Class C, the holder must attend education) before January 2nd. The fines for the penalty points must be paid on January 1st to ensure the points are automatically reset to 12 on January 2nd. The key point is that the fines must be paid. 2. Timely renewal: An expired license without renewal is equivalent to driving without a license. However, it can be renewed within one year of expiration, but a retest is required. Points can only be deducted after renewing the license.

What is the normal tire pressure for Geely Boyue?

The tire pressure for Geely Boyue is 220kpa, and the generally recommended normal tire pressure is between 220kpa-250kpa. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: standard tires should be 2.4-2.5bar; reinforced tires should be 2.8-2.9bar; while the maximum pressure should not exceed 3.5bar. However, due to seasonal factors, the tire pressure may fluctuate within the standard range. In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2bar. In summer, the tire pressure can generally be set at the lower limit of the standard tire pressure, such as 2.4bar for standard tires. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures.
