What Causes Bad Odor Inside the Car?

Reasons for bad odor inside the car: 1. The extensive use of plastic, rubber, and other materials in car interiors. The organic solvents and additives in these materials gradually release into the cabin environment during vehicle use. This is one of the main causes of unpleasant odors inside the car, especially in new cars. 2. Odor caused by the cabin air filter. Many car owners report a sour, musty smell blowing out when the air conditioning is turned on, which is quite unpleasant but tends to fade after a while. In fact, this odor is a sign that the cabin air filter needs replacement, as it has become moldy due to bacterial decomposition. Replacing the filter will alleviate the odor. 3. Odor caused by the evaporator core. If the odor persists after replacing the cabin air filter, the issue likely stems from the evaporator core. Mold growth inside the evaporator core cannot be resolved by simply changing the filter; instead, cleaning the evaporator core and air conditioning ducts is necessary. 4. Lastly, individual habits vary not only in driving but also in car usage. Differences in how the car is used can also lead to unpleasant odors, such as eating or smoking inside the vehicle, which naturally causes odors over time.

Where is the car timing belt located?

In a car engine, the timing belt is generally located at the front of the engine, behind components such as the alternator belt and fan belt. Function of the timing belt: The primary role of the timing belt is to drive the engine's valve train. It connects the timing gear on the engine cylinder head at the top and the crankshaft timing gear at the bottom, ensuring that the engine's intake and exhaust valves open or close at the appropriate times to allow the engine cylinders to properly intake and exhaust air. More relevant information is as follows: 1. The timing belt is a wear-and-tear component. If it breaks, the camshaft will not operate in sync, which can lead to severe damage due to valve and piston collision. Therefore, the timing belt must be replaced according to the mileage or time interval specified by the manufacturer. 2. During engine operation, the four processes of intake, compression, combustion, and exhaust continuously occur in the cylinders. Each step must be synchronized with the movement and position of the pistons to coordinate intake, exhaust, and piston movement. The timing belt acts as a "bridge" within the engine, transmitting power from the crankshaft to the corresponding components. 3. Many high-end vehicles use metal chains instead of belts to ensure the stability of the timing system. Since a broken timing belt can cause internal valve damage, posing significant risks, manufacturers typically specify a replacement cycle for the timing belt.
