What Causes Excessive Emissions?

Where is the sunroof drain pipe of the 2013 Bora?

The sunroof drain pipes are usually located inside the A-pillars and C-pillars of the vehicle. When water enters the sunroof channel, it flows to the drain holes and then exits the vehicle through the drain pipes. If the sunroof drain holes or pipes are blocked by debris, water will accumulate in the sunroof channel and eventually overflow into the interior, soaking the headliner. Below is an introduction to the Bora's sunroof drain outlets: 1. Total number of drain outlets: The Bora's sunroof has four drain outlets, one at each corner (front left, front right, rear left, rear right). The two rear drain outlets are the easiest to locate, positioned under the chassis near the rear wheels, one on each side. 2. Location of drain outlets: The front drain outlets are inside the A-pillars on both sides. Normally, water drains directly through the gaps in the vehicle. 3. Drain outlet maintenance: Improper maintenance of the sunroof can easily lead to clogged drain outlets. Once the sunroof drain outlets are blocked, water may leak into the car during rain. 4. Drain outlet cleaning: If the vehicle is parked for a long time, it's best to thoroughly clean the sunroof with talcum powder to prevent the rubber seals from chemically reacting with the air and aging naturally. 5. Drain outlet sealing: Pay attention to the sunroof's sealing strips. Check if the strips show signs of aging or poor sealing. If there are issues with the sealing strips, they should be replaced.

Can Car Interiors Be Repainted?

Car interiors can be repainted. Changing the color of a car's interior does not affect the vehicle's annual inspection, but exterior modifications will impact the inspection. The new "Road Traffic Safety Law" clearly stipulates that no unit or individual may assemble motor vehicles or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. The structure of a vehicle includes four rigid standards: body color, length, width, and height, as well as the relevant technical parameters of the engine. Before modifying a licensed vehicle, the owner must register and declare the modification to the vehicle management office. The modification can only proceed after the vehicle management office reviews and approves the technical report. After the modification is completed, the owner must also complete the modification change procedures at the vehicle management office. Whether the modification is legal depends on whether the vehicle matches the photo on the vehicle registration certificate and the technical parameters from the factory. If it does not comply with the regulations, it will not pass the annual inspection. Interior spray painting for color change involves using specialized paint to alter the color of surfaces. This method is relatively mature abroad, where leather can retain its color for a long time without fading. Whether the dyes used for interior spray painting in China can also achieve long-lasting color retention remains to be seen over time.

Where to Buy Driving Test Insurance in 2021?

In 2021, you can purchase driving test insurance on Alipay or Taobao. Below is an introduction to auto insurance: Introduction: Types of auto insurance, also known as motor vehicle insurance, referred to as types of vehicle insurance. Content: It refers to a type of commercial insurance that covers personal injury or property damage caused by natural disasters or accidents involving motor vehicles. Auto insurance is a type of property insurance, and within the field of property insurance, auto insurance is a relatively young category. Reason: This is because auto insurance emerged and developed alongside the appearance and popularization of automobiles. At the same time, unlike modern motor vehicle insurance, in the early stages of auto insurance, the main coverage was third-party liability insurance for automobiles, which gradually expanded to include risks such as collision damage to the vehicle body.

Do 7-seater vehicles still require lettering in 2021?

Whether 7-seater vehicles require lettering in 2021 depends on the nature of the vehicle. Generally, non-commercial household 7-seaters are not mandated to have lettering, while commercial 7-seaters must have it. Below are the relevant details about lettering: Purpose: For travel safety and the safety of passengers, the aim is to remind drivers to load passengers according to regulations, enhance public supervision of van transportation, raise awareness of traffic safety among the public, and consciously resist illegal activities such as overloading to reduce road safety hazards. Consequences of not having lettering: According to relevant regulations, commercial motor vehicles must have mandatory lettering. Vehicles without lettering are not allowed on the road by traffic police. If caught, the driver may face fines and penalty points.

Can the BMW 5 Series Use 92 Octane Gasoline?

BMW 5 Series cannot use 92 octane gasoline; it should use 95 octane gasoline, as this fuel grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, it can also be found on the fuel tank cap. Typically, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is higher, 98 octane gasoline should be selected. However, with the application of new technologies, the fuel grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower octane gasoline, as factors like ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after consumption. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles designed for lower octane gasoline, using higher octane gasoline will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher octane gasoline, using lower octane gasoline can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstably. Mild knocking only increases noise without significant engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.
