Turbocharger failures: 1. Foreign object ingestion failure in turbocharger: The compressor side is damaged by foreign objects, possibly due to poor intake pipe sealing allowing unfiltered air to enter the compressor wheel, or failure to replace air filters as required or using inferior filter elements; 2. Radial damage failure by foreign objects: Damage to components within diesel engine cylinders or foreign objects entering the exhaust manifold during maintenance - any foreign object can disrupt the dynamic balance of the turbocharger rotor, eventually leading to rotor seizure or shaft fracture; 3. Contaminated lubricating oil failure in turbocharger: The engine uses non-compliant lubricating oil filters or inferior filter elements, with the filter element being punctured during operation or the engine's main oil passage filter becoming blocked.

What to Do When a Motorcycle Fails to Start After Long-Term Storage

There are mainly four methods to address the issue of a motorcycle failing to start after long-term storage. Here are detailed explanations of these four methods: Replace the gasoline: In general, if gasoline is not used for more than six months, its quality will deteriorate. It may also develop gum deposits, which can cause the engine to gum up and make starting difficult. Therefore, when the motorcycle fails to start, it's best to replace the old gasoline with fresh fuel. Manually rotate the crankshaft quickly: When a motorcycle is left unused for a long time, the engine loses lubrication from the oil, leading to low cylinder pressure and insufficient lubrication for the crankshaft components. In this case, manual intervention by quickly rotating the crankshaft can help. Recharge the battery: The battery of a motorcycle that hasn't been used for several months is usually in a discharged state. Simply recharge the battery in time. Replace the spark plug: If a motorcycle is left unused for an extended period, the spark plug is likely to become damp. Once damp, the motorcycle is highly likely to fail to start. At this point, the spark plug should be checked first. If the issue lies with the spark plug, it should be replaced with a new one.

What is the fuel consumption per 100 kilometers for a 1.5L naturally aspirated engine?

1.5L engine cars typically have a fuel consumption of 6-8 liters per 100 kilometers. When driving on highways at a speed of around 90 km/h, the fuel consumption is approximately 6.5L/100km; for urban and suburban roads, the combined fuel consumption is around 7.5 liters. Specific details are as follows: 1. Large displacement: Generally, a larger displacement means the engine releases more energy per unit time (converting chemical energy from fuel into mechanical energy), which also means better 'power performance.' It's like comparing a teenager to a healthy adult—the adult is naturally more efficient at physical labor. Therefore, SUVs and sports cars usually have relatively larger displacements. 2. Cylinder displacement: The working volume that the piston moves from the top dead center to the bottom dead center is called the cylinder displacement; if the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is usually expressed in liters (L).

How to Handle Recalled Vehicles?

After a vehicle is recalled, it undergoes a series of inspections and repairs until there are no related safety issues or non-compliant equipment. Here is extended information about the vehicle recall system: 1. Introduction to the vehicle recall system: The vehicle recall system refers to the process where vehicles already on the market are found to have defects due to design or manufacturing issues, which do not comply with relevant regulations and standards and may lead to safety or environmental problems. 2. Manufacturer's actions after a recall: The manufacturer must promptly report to the relevant national authorities about the product issues, the causes of the problems, and the improvement measures, then submit a recall application. Upon approval, modifications are made to the vehicles in use to eliminate potential hazards. Manufacturers are also obligated to keep users informed about the situation, which is crucial for protecting consumers' legal rights. 3. According to the "Regulations on the Recall of Defective Automotive Products": Article 24 states that if a producer violates these regulations under any of the following circumstances, the product quality supervision department shall order corrections and impose a fine ranging from 1% to 10% of the value of the defective automotive products; any illegal gains shall be confiscated; in severe cases, the licensing authority may revoke relevant licenses.

Why Won't the Wiper Return to Its Original Position?

If the wiper does not return to its original position, you should check whether the wiper is stuck or has an open circuit; check if the hardware is sufficiently lubricated; and inspect whether the wiper rubber is aged or if there is dust or other foreign objects trapped between the rubber and the windshield. The inspection methods are as follows: 1. Check if the wiper is stuck or has an open circuit: After confirming that the motor is functioning properly, proceed to check other potential issues besides the motor, such as whether the wiper has an open circuit or is stuck. These are relatively simple checks. 2. Check if the hardware is sufficiently lubricated: If none of the above issues are present, inspect whether the hardware lacks lubrication, causing excessive friction and preventing the spring from automatically returning to its original position. Apply lubricating oil to the surface of the card. 3. Check if the wiper rubber is aged or if there is dust or other foreign objects trapped between the rubber and the windshield: If the wiper's return is obstructed, clean the wiper rubber and windshield with a damp cloth. Replace the wiper or rubber if necessary. 3. Reset method: There are reset contacts inside the wiper motor. After turning off the wiper, the motor continues to operate until it reaches the reset contacts, at which point the wiper stops working. This point is where the wiper blade is at the lowest position on the windshield.
