An Alto minicar was in motion when a rhythmic, continuous noise emerged from the lower part of the engine. The sound was heavy and metallic, resembling a "clunk," and the vehicle would vibrate severely when the issue became more pronounced. Upon investigation and testing, it was determined that the abnormal noise originated from the lower part of the engine. The sound became more noticeable during rapid acceleration or deceleration, and it remained consistent regardless of the engine's temperature. This suggested a potential issue with the crankshaft bearing. Typically, the rear main bearing produces a dull, heavy sound, while the front bearing tends to be lighter and more brittle. However, in this case, the sound was clearly out of the ordinary. The possible causes of the abnormal noise at the crankshaft bearing include: If the issue is caused by excessive wear on the axial thrust washer, the resulting abnormal noise may be non-rhythmic due to excessive axial clearance and misalignment of the crankshaft. However, if the noise is caused by other factors, it often becomes more noticeable when the engine is cold after starting. During the abnormal noise, the cylinder head of the affected cylinder may vibrate in sync with the sound. When performing a single-cylinder ignition cut-off test, the noise remains largely unchanged. However, if two adjacent cylinders are disabled simultaneously, the abnormal sound may decrease or become less noticeable, indicating a problem between those two cylinders. After removing the crankshaft, it was discovered that the axial thrust washer had worn significantly. Replacing it with a new one and reassembling the engine resolved the issue, confirming the cause of the noise.

The primary purpose of a Smart Toilet seat is to provide gentle and effective cleansing after using the toilet. It uses water jets to spray a controlled stream of water onto the user's intimate areas, replacing the need for traditional toilet paper. This not only ensures a more hygienic clean but also reduces irritation and discomfort associated with wiping.
Smart bidet seats often come with adjustable water pressure and temperature settings, allowing users to personalize their cleansing experience according to their preferences. Some models may also offer additional features such as oscillating or pulsating spray modes for a more comprehensive clean.
In addition to cleansing, bidet seats may offer additional functionalities for enhanced comfort. Many models are equipped with a heated seat, providing warmth and comfort during colder seasons. Some bidet seats also feature air dryers that eliminate the need for toilet paper altogether, further reducing waste and promoting environmental sustainability.
The installation of a bidet seat is typically straightforward, requiring only basic plumbing skills. Most bidet seats can be easily attached to the existing toilet bowl using mounting brackets and connecting hoses. Some models may require access to a nearby electrical outlet for certain features like seat heating or air drying.
