What cleaning agent should be used to wash a motorcycle?

Engine cleaner should be used to wash a motorcycle. Below is relevant information about cleaning agents: Function of cleaning agents: Engine internal cleaning agents are products developed to address the formation of sludge, gum, carbon deposits, paint films, dirt, and other sediments inside the lubrication system. Composed of highly effective cleaning components, they are additives capable of automatically cleaning the internal system of the lubrication system. Gasoline cleaner: The main component of engine carbon deposits is impurities in gasoline. Therefore, gasoline with higher cleanliness has a weaker tendency to form carbon deposits. Choosing a genuine gasoline cleaner helps remove carbon deposits inside the engine, effectively preventing the formation of carbon deposit layers on metal surfaces, gradually activating existing carbon deposit particles and slowly removing them, thereby protecting the engine from damage.

Which invention principle is used in automotive airbags?

Automotive airbags operate on the principle that substances such as sodium azide or ammonium nitrate inside the airbag rapidly decompose upon a severe collision during high-speed driving, producing a large volume of gas to inflate the airbag. Below is relevant information about airbags: Introduction to airbags: The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. Protection principle of airbags: When a vehicle experiences a certain level of collision force, the airbag system triggers a chemical reaction similar to a small explosive detonation. The airbag, hidden within the vehicle, inflates and deploys instantly, positioning itself between the occupant and interior components before impact occurs. Upon contact with the occupant, the airbag begins to deflate through vent holes on its surface, cushioning the impact.

What Causes the Rattling Noise Like Pebbles in the Car?

Rattling noises resembling pebbles inside the car can be attributed to door rattles, sunroof rattles, or dashboard rattles. For door rattles, first check if the screws are loose. Sunroof rattles are generally normal. Dashboard rattles are usually related to the overall build quality and materials of the vehicle. Below are detailed explanations of the causes: Door Rattles: Door rattles occur because the door structure is relatively simple. First, check if the screws are loose. Sunroof Rattles: Sunroof rattles are generally normal. Over years of use, small pebbles or dust may accumulate in the sunroof tracks, and over time, poor sealing can lead to rattling. Inspect the sunroof's sealing and replace the weatherstrip if necessary. Dashboard Rattles: Dashboard rattles are typically related to the vehicle's overall build quality and materials. Consider whether the dashboard panel has been removed before, if a navigation system wiring was installed, or if it was reassembled properly. Alternatively, visit a repair shop for a thorough inspection.

What causes the buzzing sound after starting the car?

Car starting with a buzzing sound is due to the excessive sensitivity of the anti-theft device. Below is the relevant introduction about car automatic alarms: Excessive sensitivity of the anti-theft device: Generally, the most common reason for the car's anti-theft horn to sound automatically is the excessive sensitivity of the anti-theft device, which causes the alarm to be triggered even with slight vibrations. If it is confirmed that there is no risk of theft, no active people, animals, or objects inside the car, the sensitivity can be adjusted to a lower level. Issues with anti-theft components or circuits: Another reason is the system's false alarm triggered by problems with the anti-theft device components or circuits. It is necessary to promptly go to a repair facility for an electrical system inspection. After identifying the problem, repair or replacement can resolve the issue.

Should car tires be replaced after five years of use?

Tires that have been in use for 5 years should be replaced promptly. The longer the tires are used, the higher the risk of tread deformation and blowouts. Tires are rubber products. When exposed to air for extended periods, especially in contact with air and sunlight, they gradually age, leading to a decline in performance and a sharp increase in the likelihood of blowouts. To extend the service life of tires, it is recommended to rotate the front and rear tires every 10,000-20,000 kilometers. Generally, front tires wear out more severely than rear tires. Rotating them ensures more even wear and prevents excessive wear on the front tires, which could render them unusable. When rotating the tires, it is also advisable to perform a four-wheel alignment and tire dynamic balancing. This helps prevent uneven tire wear that may necessitate premature replacement. Four-wheel alignment adjusts the suspension parameters to ensure the wheels are aligned straight forward, while dynamic balancing uses counterweights to ensure the weight distribution of the entire wheel is balanced. Before driving, always check the tire pressure—neither too high nor too low. Generally, maintain it around 2.2-2.5 Bar. In winter, due to the effects of thermal contraction, tire pressure tends to drop as temperatures decrease. It is recommended to inflate the tires appropriately during colder months.

Which year was the Haojue 125-2 old model produced?

The Haojue 125-2 old model was produced between July 2010 and July 2019. Below are some relevant introductions about motorcycle riding: Cooling before washing: Always let the hot engine cool down before washing. Suddenly rinsing the engine, exhaust pipe, and other components with cold water can damage the oil seals in various parts due to thermal expansion and contraction, leading to engine oil leakage. Many motorcycle enthusiasts experience slight engine oil leakage due to this reason. It can also cause the chrome plating at the connection between the exhaust pipe and the engine to peel off, oxidize, and rust. Wipe cleaning: It is best not to directly rinse areas such as the headlight, left and right handrails, ignition switch, exhaust pipe outlet (it's better to block it with something), horn, spark plug, air filter, and battery with water. These areas contain circuits, and getting them wet can cause short circuits or leakage, resulting in issues like non-functioning lights, unresponsive horn, failure to start, and weak performance. It is recommended to use a cloth for wiping. Drying with a cloth: After washing the motorcycle, the entire vehicle should be dried with a dry cloth, especially areas like the ignition switch, instrument panel, left and right handrails, spark plug, and fuel tank cap. Special attention should be paid to removing the spark plug cap and shaking it a few times to remove any water inside the sleeve, as it may affect ignition.
