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.
