The steps for the manual stationary exhaust self-cleaning of the Fengjun 7 are: 1. Turn on the power without starting the vehicle; 2. Press and hold the regeneration switch without releasing it. The dimensions of the Fengjun 7 are: length 5095mm, width 1800mm, height 1760mm, with a wheelbase of 3050mm. It features a front-engine, rear-wheel-drive layout, with a double-wishbone torsion bar spring independent front suspension and a leaf spring non-independent rear suspension. The Fengjun 7 is equipped with a 2.0T turbocharged engine paired with a 6-speed manual transmission. This engine delivers a maximum power of 120kW and a maximum torque of 330Nm, featuring direct fuel injection technology and an aluminum cylinder head with an iron cylinder block.

I recently tried the manual regeneration on my FENGJUN 7 and would like to share the experience. First, park your car on level ground, engage the handbrake, and put it in neutral—crucially, stay away from hazardous areas like gas stations. Then, start the engine and let it idle for five minutes to warm up; the coolant temperature gauge should reach the middle position. At this point, locate the regeneration button on the left side of the dashboard, press and hold it for three seconds, and the dashboard will display a 'Regeneration in Progress' message. Keep the engine running without shutting it off—you'll hear the RPM automatically rise to around 2000, and you'll need to wait approximately 20 to 30 minutes. During this time, avoid touching the accelerator or brake, don’t turn on the AC, and definitely don’t step out for a smoke. Once completed, the RPM will automatically drop back to idle, and if the fault light turns off, it means the process was successful. This method is particularly useful for urban drivers who frequently take short trips to periodically clean the DPF.

Last time I helped a friend perform a DPF regeneration on his Great Wall Wingle 7, I noticed several key points. The vehicle must be parked in a well-ventilated area because exhaust temperatures can soar to 600°C. Before starting, check that the DEF fluid level is sufficient and ensure the fuel tank has at least a quarter tank remaining, otherwise the process will abort. After starting the engine, wait until exhaust temperatures exceed 200°C before pressing the regeneration button. I prefer to open the hood beforehand to dissipate heat and prevent engine bay overheating. Monitor dashboard indicators closely during the process - if any warning lights flash, stop immediately. During winter operations, louder engine noise is normal, but any burnt smell should raise immediate concern. It's advisable to keep a timer handy; if regeneration hasn't completed within 25 minutes, check for trouble codes.

How to Replace the Battery in a Volkswagen T-Roc Car Key?

Pull out the mechanical key by releasing the clip at the end of the key, then stand the key upright and use a screwdriver to pry it open. After separating the casing, remove the old battery directly and observe the battery type to determine the battery model. Replace with a new battery and secure the device in reverse order. Improper battery replacement may damage the car key. Before replacing the battery, check the battery model in advance. When selecting a battery, ensure the size, specifications, and rated voltage match those of the old battery.

How to Turn On the Rearview Mirror Heating in a Grand Cherokee?

First, start the car and begin driving smoothly. After pressing the button, a small yellow light will illuminate, indicating that both the rearview mirror and rear window heating are activated. The heating will automatically turn off after approximately 10-15 minutes. An electric heating element is installed inside the lenses of both side rearview mirrors. When the rearview mirror heating function is turned on, the heating element will quickly warm up to a set temperature. The rearview mirror heating function refers to the ability of the rearview mirrors to be heated via electric wires embedded behind the lenses when driving in rainy, snowy, or foggy weather conditions.

What to do if the car door is slightly dented?

As long as the paint on the dented area of the car door is not peeling or chipped, it can be repaired with professional tools without the need for panel beating and repainting. You can purchase a suction bridge-type repair device online. This device uses suction cups to pull out the dented area, with larger suction cups used for bigger dents. You can also buy a leveling pen to flatten the dent by tapping. This method is suitable for car doors with smaller dents. If the car door is severely dented and cannot be repaired, it will have to be replaced. If there is an auto parts store nearby, you can go directly to purchase a new one and then take it to a repair shop. Take protective measures to prevent further dents. Put a protective cover on the car door to prevent it from hitting walls or other sharp objects when opening, which could cause dents.

What are the effects of tire slippage with a burnt smell?

Tire slippage with a burnt smell does not have a significant impact, but it is important to pay attention to tire maintenance. Below is an introduction to tires: 1. Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are usually installed on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. 2. Performance: Tires are often used under complex and demanding conditions. During operation, they endure various deformations, loads, forces, and high and low temperatures. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning performance. Additionally, they require high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, highlighting the significant role of tires in rubber usage. 3. Specifications: Specifications are the geometric parameters and physical performance indicators of tires. Tire specifications are commonly represented by a set of numbers, where the first number indicates the tire section width and the second number indicates the rim diameter, both measured in inches.

How to Install an Aluminum Alloy Police Badge?

Aluminum alloy police badges can be installed depending on their size. Larger ones can be affixed using epoxy resin. Below is an introduction to vehicle modifications: 1. Introduction: Vehicle modification refers to altering the external appearance, interior design, and mechanical performance of a factory-produced vehicle according to the owner's needs, primarily including body modifications and performance upgrades. 2. Brakes: There are multiple methods to upgrade the braking system, such as installing larger brake discs, multi-piston brake calipers, and high-performance, heat-resistant brake pads. Additionally, higher-grade brake fluid or metal high-pressure brake lines can be installed. 3. Suspension: Suspension system modifications can generally be categorized into replacing shock absorbers, reinforcing suspension structural components, and installing stabilizer bars. Among these, shock absorber replacement is the most impactful and commonly modified component. Upgrading shock absorbers typically involves installing units with stiffer damping, higher quality, and better compatibility with springs.
