Is It Normal for a Car's Exhaust Pipe Not to Drain Water?

It is normal for a car's exhaust pipe not to drain water. When gasoline burns completely, it produces water and carbon dioxide. At high temperatures, water exists as steam and is colorless and transparent. However, when the temperature drops below 100 degrees Celsius, the steam condenses into water. If the condensed water droplets are very small and suspended in the air, the steam appears as white gas. In colder environments, white smoke from the exhaust pipe is actually steam. If the condensed water droplets accumulate, they may drip. The car's exhaust pipe is installed between the engine's exhaust manifold and the muffler, providing flexible connections for the entire exhaust system. This helps reduce vibration and noise, facilitates installation, and extends the lifespan of the exhaust muffler system.

What does NVH mean for a car?

NVH in cars refers to Noise, Vibration, and Harshness, which is a comprehensive indicator for measuring automotive manufacturing quality, providing users with subjective and surface-level perceptions. NVH issues in vehicles are one of the key concerns for major global automotive manufacturers and component suppliers. For automobiles, NVH problems are ubiquitous. Based on their sources, NVH can be categorized into three main areas: engine NVH, body NVH, and chassis NVH, with further subdivisions including aerodynamic NVH, air conditioning system NVH, road driving NVH, and braking system NVH.

How to Add Refrigerant?

There are two methods for adding refrigerant, but the procedures differ depending on the state of the refrigerant: 1. Liquid refrigerant must only be added through the high-pressure side, which is safer and faster, making it suitable for initial filling after evacuation. Note that liquid refrigerant must be added in an inverted position. 2. Gaseous refrigerant must be added through the low-pressure side. Due to its slower filling speed, this method is suitable for supplemental filling. Methods to determine if your car needs refrigerant oil: 1. If the air conditioning reaches the set temperature quickly after normal operation for a period of time, it indicates normal conditions; otherwise, refrigerant oil needs to be added. 2. Measure the temperature difference between the air inlet and outlet of the indoor unit with a thermometer. If the difference is below approximately 8°C, refrigerant oil needs to be added.
