《Go on a study tour to Qufu》 -- FIRE Company

When the high-speed train get into the platform of this "Oriental Holy City", the sunlight was gilding the ten-thousand-foot palace wall. As a stop of the study tour practice, this city built with "The Analects of Confucius" welcomed our seven-person study group with the chirping of cicadas and the fragrance of locust trees.When the high-speed train get into the platform of this "Oriental Holy City", the sunlight was gilding the ten-thousand-foot palace wall.

As a stop of the study tour practice, this city built with "The Analects of Confucius" welcomed our seven-person study group with the chirping of cicadas and the fragrance of locust trees.   The tolling of the bell: The thousand-year-old ritual music of Qufu's opening ceremony reappears   When a beam of sunlight swept across Nishan, three hundred ceremonial guards dressed in Zhou Dynasty ceremonial robes were already standing solemnly in front of the ten-thousand-foot palace wall of the Ming Dynasty's ancient city in Qufu. The chime bells are hung on the bell stand. In a wonderful time, the staff members held bamboo slips and recited loudly, "The thousand-year-old rites and music return to the Eastern Shandong -". Just as they finished speaking, the bell rang, and the sound waves hit the 8.6-meter-high ancient city, causing flocks of birds to fly up.     At noon, visit the Confucian Temple and Mansion: Measure the classics among the pillars with your feet   Stepping on the dents on the bluestone slabs - those potholes, I felt as if I could hear the bamboo slips of "The Analects of Confucius" clanging in the wind. When touching the stone steps in front of the hall, the tour guide said softly, "This dragon beard pattern was made bit by bit by the craftsmen of the Ming Dynasty." Suddenly, I felt that those patterns might not be decorations but rather the marks of time itself. On the walls of the residences on the west side of the Confucius Mansion, the divine beasts have been gazing for four hundred years. In the Wanli era, workers cracked the walls in flames, warning people of the consequences of self-destruction due to greed.     Living in a shabby alley: being neighbors with Yan Hui   When checking into the renovated Yanmiao Homestay area, you can see the sign of "Danpiao Lane" on your way to the dining area. Sunlight slanted through the plaque of "Louxiangfang" at the entrance of the alley, stretching the shadow of the QR code of the "Yan Huiju" ruins onto the bluestone of the Ming Dynasty. Among those interlaced beams of light, there are pottery shards from the Spring and Autumn period, copper coins from the Song Dynasty, and optical fibers from 2025, as if quietly shining in the crevices of the bluestone.       Confucius Museum -" Without Confucius, time would be like a long night."   When the fingertips touch the bronze tripod of the Western Zhou Dynasty, the 54Hz "cultural relic heartbeat" awakens the perception through bone conduction. The digital classics wall on the second floor subverts perception - a Kenyan scholar's annotation of the metaverse "Friends come from afar" proves that classics are always resonating with The Times. When leaving the museum, looking up, Confucius' constellation overlapped with SpaceX's Starlink trajectory. The 85% proportion of dark matter in the universe is just like cultural influence: what truly shapes civilization are always those invisible yet ubiquitous spiritual particles.     The one-week study tour was like a cultural CT scan. When the return train started, the 4K images on my phone were all telling me: Tradition is not a static specimen, but a flowing river. This is probably the contemporary footnote of "reviewing the old to learn the new".

Does a car need a turbocharger?

A car doesn't necessarily have to have a turbocharger. A turbocharger is a device used to increase the intake air volume of an engine, thereby enhancing its power and torque. It utilizes the inertial impact force of the exhaust gas discharged from the engine to drive the turbine fan blades and compress the air sent from the air filter pipe, pressurizing it into the cylinder to achieve the purpose of enhancing the engine's power output.     1. Advantages of turbochargers   Enhanced power ‌ : Turbochargers can significantly increase the power and torque of the engine, making the vehicle more powerful and accelerating faster. Improving fuel economy ‌ : At the same power, turbocharged engines may be more fuel-efficient than naturally aspirated engines. This is because turbocharged engines can generate greater power with a smaller displacement, thereby reducing fuel consumption. Reducing exhaust emissions ‌ : Since engines can generate greater power after being supercharged, turbocharging technology helps to reduce exhaust emissions to a certain extent.   2. Possible problems with the turbocharger   The power output is not linear ‌ : Due to the working principle of turbocharging, it responds slowly to sudden changes in the throttle, resulting in turbo lag. This may cause the driver to feel the discontinuity of power output when accelerating. High maintenance costs in the later stage ‌ : turbochargers generate a large amount of heat during operation and require more advanced fully synthetic engine oil for heat dissipation and lubrication. In addition, the maintenance cost of turbochargers is relatively high. Once a malfunction or damage occurs, the cost of repair or replacement may be quite expensive. Engine lifespan may be affected ‌ : Due to the significant increase in the working pressure and temperature of the engine after supercharging, the lifespan and mechanical performance of the engine may be affected.   In conclusion, whether a car needs a turbocharger depends on the actual needs and budget of the car owner. When making a choice, car owners should comprehensively consider factors such as the vehicle's purpose, purchase budget, and later maintenance costs to make the decision that best suits them.

Turbocharger failure? It can be easily fixed by replacing the repair kit

Self-check and repair kits solution for Turbocharger faults   Common Fault Identification   Insufficient power: Weak acceleration, accompanied by black smoke (wear of turbine blades or sealing rings) Abnormal oil consumption: Blue smoke is coming out of the exhaust pipe (the aging of the sealing ring causes oil to seep into the combustion chamber) ​   Abnormal noise: Metal friction sound (journal bearing damage)   ​Main Operating Steps of the Repair Kit ​​ 1.Disassemble and clean   Use special tools to separate the turbine from the compressor housing   Thoroughly remove the carbon deposits with a chemical cleaner and check if the impeller is scratched   2. Replacement of key components Piston ring: If the thickness difference between new and old is larger than 0.1mm, it needs to be replaced. When installing, align the notch with the locating pin Journal bearing: Apply high-temperature grease and control the axial clearance at 0.03-0.08mm O-rings: Oil-resistant fluorine rubber material is preferred. Apply sealant lightly before installation 3. Assembly and debugging Assemble in the reverse order. Tighten the bolts diagonally in three steps (reference torque: 25-30N·m). After loading the vehicle, let it idle for 10 minutes to check if there is any leakage at the oil pipe interface Precautions after Maintenance Avoid sudden acceleration during the first drive and change the engine oil within 500 kilometers Check the intake pipe of the turbocharger every 20,000 kilometers to prevent secondary damage from impurities

Turbocharger Diagnosis Process--Oil Leakage Diagnosis

Oil leakage at the compressor end (check whether there are obvious traces of oil on the compressor housing and outlet of the turbocharger)   1.Check if the turbocharger intake pipe is throttled or deformed Yes: Replace the intake pipe to eliminate the throttling phenomenon 2. Check if all intake and exhaust pipes are loose or broken Yes: Tighten the pipes and replace the damaged pipes 3. Check if the air filter is too dirty Yes: Clean or replace the filter element 4. Check if there are oil stains at the intersection of the turbocharger compressor intake pipe Yes: Check if the air pump is leaking 5. Check if the compressor wheel is damaged by foreign objects Yes: Clean and repair the air intake system and replace the turbocharger   6. Check if the turbocharger shaft and radial clearance are enlarged (whether the blades are rubbing against the housing, etc.) Yes: Eliminate the factors that cause the turbocharger clearance to expand and replace the turbocharger   7. Check if the turbocharger return oil pipe is bent or damaged, resulting in return oil throttling Yes: If the return oil is blocked or bent and deformed, it should be repaired or replaced, and the return oil pipe should be kept vertically downward as much as possible   Error diagnosis method: If you start the engine to observe whether there is oil leakage after removing the connecting pipe between the compressor housing outlet and the engine inlet, there will definitely be oil drops spraying out from the compressor outlet. This is not caused by a turbocharger failure, but because this diagnostic method will cause the internal pressure of the compressor end to fail to build up normally, and the lubricating oil will flow to the compressor under the action of the inlet oil pressure, which will 100% cause oil leakage.   Oil leakage at the turbine end (check whether there are obvious traces of oil on the turbocharger turbine housing and outlet) 1. Check if the turbocharger shaft and radial clearance have become larger (whether the blades are rubbing against the housing, etc.) Yes: Eliminate the factors that cause the turbocharger clearance to expand and replace the turbocharger 2.For newly installed turbochargers, check if too much lubricating oil is used for pre-lubrication Yes: Excess lubricating oil will be burned and no measures are required 3. Check if the turbocharger return oil pipe is bent or damaged, resulting in return oil throttling Yes: If the return oil is blocked or bent, it should be repaired or replaced, and the return oil pipe should be kept vertically downward as much as possible   If the above steps do not solve your problem, please refer to other tests.   Other tests: 1. Check whether the crankcase is too full of lubricating oil Refer to the requirements of the engine manufacturer and adjust the oil level in the crankcase to an appropriate height 2. Check whether there is sludge, carbon deposits in the intermediate oil chamber, or the oil return port is blocked, resulting in poor oil return Clean the oil return chamber and the turbocharger oil return port, and repair the engine lubrication system if necessary 3. Check whether the engine crankcase breather is blocked Refer to the engine manufacturer's maintenance manual 4. Check whether the engine has any faults (oil-gas separator failure, etc.) Refer to the engine manufacturer's maintenance manual   Correct driving habits can reduce 80% of oil leakage faults: Is the vehicle idling for too long (more than 20 minutes) Yes: Avoid idling for long periods of time (more than 20 minutes). Just wipe off the oil. No effect on the quality of the turbocharger   Is the vehicle using exhaust brakes for a long time? Yes: Long-term use of exhaust brakes can easily cause a small amount of oil leakage from the turbocharger. Just wipe off the oil. No effect on the quality of the turbocharger.   Is the engine in reverse towing conditions for a long time, such as long downhill driving Long-term reverse towing conditions can easily cause a small amount of oil leakage from the turbocharger. Just wipe off the oil. No effect on the quality of the turbocharger.
