The manual regeneration function of the Fengjun 5 is simple and easy to use. Let me guide you step by step. Park in a safe and open area, not in a garage, as the high exhaust temperature may pose a carbon monoxide risk. Then, keep the engine running in neutral—don’t turn it off. Locate the DPF regeneration button or a specific key combination on the steering wheel or dashboard, hold it for a few seconds to activate, and you’ll hear the engine sound louder with increased RPM, which is normal. The regeneration process takes about 15-20 minutes, and the dashboard indicator light will change—wait for it to turn off, indicating completion. During operation, avoid getting near the rear exhaust pipe to prevent burns, keep away from flammable materials, and ensure good ventilation. If manual regeneration isn’t performed regularly, DPF clogging may lead to reduced power or even failure to start. Usually, driving at high speeds will trigger automatic cleaning, but if you frequently encounter traffic jams or drive at low speeds for extended periods, it’s best to manually trigger it to avoid unexpected issues. Always refer to the user manual to confirm the exact procedure—safety first!

What engine is used in the Chevrolet Boyue?

The engine of the Chevrolet Boyue is independently produced, and having its own intellectual property rights is a highlight of the Boyue. The engine model used in the Chevrolet Boyue is the JLE-4G18TDB, with a maximum horsepower of 184 HP, a maximum power of 135 KW, a maximum power speed of 5500 rpm, and a peak torque of 300 N.m. For daily maintenance of the Chevrolet Boyue's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and keep the oil level moderate; When engine oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and the oil cannot pass through the filter element, it may burst the filter element or open the safety valve, bypassing through the relief valve and carrying contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

Is it Vehicle U-turn or Turnaround?

The correct term is vehicle u-turn. According to the "Great Chinese Dictionary," the explanation of "u-turn" refers to vehicles or vessels turning in the opposite direction. The original clauses mentioned in the Road Traffic Law and the "Urban Road Traffic Signs and Markings Setting Standards" both use the term "u-turn." Permissible u-turn situations: Intersection with a u-turn sign: If there is a clear u-turn sign at the intersection, a u-turn can be made. If there is a u-turn signal light, the u-turn must follow the signal's instructions. In the absence of a signal light, a u-turn can be made based on the specific situation, provided it does not hinder other vehicles or pedestrians. Intersection without explicit prohibition of u-turns or left turns: If there is no explicit prohibition of u-turns at the location, a u-turn is allowed. "No explicit prohibition of u-turns" means that as long as there are no "no u-turn signs," "no left turn signs," or solid center lines at the intersection, a u-turn can be safely made. Yellow grid lines also permit u-turns: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary parking, important facility entrances, or other necessary locations. Any vehicle stopping on these grid lines (including waiting for traffic lights) is considered a violation. Although parking is prohibited in yellow grid zones, u-turns are allowed. As long as there is no central barrier, yellow grid lines are equivalent to "u-turn permitted." Intersection with a u-turn signal light: This is straightforward—if there is a u-turn signal light, a u-turn can only be made when the light is green. Simultaneous presence of "no left turn" and "u-turn permitted" signs: U-turns are allowed, but left turns are prohibited. However, "no u-turn" is not the same as "no left turn." Precautions when making a u-turn at an intersection: Observe road markings—if they are solid lines, u-turns are prohibited under any circumstances, and the driver should continue forward to find a suitable location. If there is a "no left turn" sign ahead, even if there is no mention of prohibiting u-turns, u-turns are not allowed at that intersection because the actions for left turns and u-turns are similar, and u-turns always involve a left turn first. U-turns must be made from the innermost left-turn lane. If the vehicle is in the second left-turn lane, u-turns are not permitted at that intersection. When making a u-turn, drivers must yield to oncoming vehicles and only proceed if it does not interfere with their normal movement; otherwise, they will bear full responsibility for any accidents. Near intersection stop lines, lanes usually have guiding arrows for vehicle direction. The leftmost lane does not always have a left-turn arrow—if a straight arrow is present, even without explicit "no u-turn" signs, u-turns are not allowed. U-turns must not be made on pedestrian crosswalks, as this constitutes a traffic violation.
