cleanzone is an in-car air purification system. Here are the relevant details about cleanzone: 1. Function: The "Cleanzone system" addresses three aspects - "incoming," "intermediate," and "outgoing" - corresponding to ensuring the air entering the cabin is clean enough, optimizing the in-car air quality, and reducing external emissions. Within 7 minutes, the Cleanzone system can control the in-car air quality and PM2.5 levels to Nordic-level fresh air, allowing users to breathe air as pure as that in Nordic regions. 2. Activation conditions: (1) All doors and windows of the vehicle must be fully closed to ensure the vehicle is sealed. (2) The air conditioning mode in the car must also be set to external circulation mode.

I often use the Cleanzone function when driving my Volvo. It's actually an in-car air quality control system specifically designed to filter out air pollutants, such as PM2.5 particles, pollen, bacteria, and even harmful volatile gases. With it turned on, the air feels fresh and crisp every time I get in the car, especially on smoggy days or during city traffic jams, significantly reducing respiratory discomfort. I frequently take my family on outings, and my kids never sneeze in the car because they're sensitive to dust. The system automatically monitors and purifies the air, requiring no manual adjustments—simple and convenient. Expanding on this topic, with air pollution being such a serious issue nowadays, this kind of feature has become an essential driving companion, not only enhancing health protection but also making long trips more comfortable and enjoyable.

What causes oil discharge from the exhaust under exhaust brake operation?

The reasons for oil discharge from the exhaust under exhaust brake operation: Damaged cylinder gasket. Poor valve sealing. Excessive clearance between the valve and the guide. Insufficient tension of the piston rings or incorrectly installed piston rings. Piston rings stuck; newly repaired engines not properly run-in, the oil discharge phenomenon will naturally disappear after a period of running-in. Other reasons include: Excessive clearance between the piston and cylinder wall: If the clearance between the piston and cylinder wall is too large and the engine does not reach the proper temperature for a long time, oil leakage faults are prone to occur. Too long low-speed ignition time: This causes the engine temperature to rise too slowly; excessive clearance in the connecting rod bearings increases the amount of oil splashed on the cylinder wall and sucked into the combustion chamber. Injection pressure too low: Injection pump pressure is too low, and the injector pressure is also too low (so-called injector dripping).
