What is the general temperature of an exhaust pipe?

Generally, the exhaust pipe temperature of small family cars ranges between 30–120 degrees Celsius. 1. Introduction: The outlet temperature of a car's rear exhaust pipe varies depending on the vehicle model, the length of the exhaust pipe, and the number of mufflers. Some modified cars can even have exhaust pipes that emit flames, with outlet temperatures reaching several hundred degrees. 2. Factors affecting temperature: The longer the exhaust pipe, the lower the outlet temperature at the tail end. Additionally, higher engine speeds result in higher exhaust temperatures. When the vehicle is idling, the outlet temperature is only around 30 to 50 degrees. 3. Temperatures at different locations: The temperature of the exhaust gas exiting the engine to the exhaust manifold is 800–900 degrees. After passing through the primary catalytic converter, the temperature drops to 600–700 degrees. The temperature at the mid-section of the muffler decreases further, typically to 200–300 degrees, while at the tail end of the muffler, it is around 150 degrees. The exhaust gas cooled by the muffler baffle is slightly above ambient temperature, ranging from 20 to 50 degrees.

Is car maintenance calculated by age or mileage?

Car maintenance intervals are determined by whichever comes first: mileage or age. Generally, engine oils are categorized into three types: full synthetic, semi-synthetic, and mineral oil. Below are the recommended replacement intervals for different types of engine oil: 1. Full synthetic oil typically requires replacement every 10,000 kilometers or once a year. 2. Semi-synthetic oil usually needs replacement every 7,500 kilometers or every 7-8 months. 3. Mineral oil generally requires replacement every 5,000 kilometers or every six months. Note: Prolonged failure to change the engine oil can lead to oil degradation, reducing its lubricating effectiveness. Without proper lubrication during engine operation, internal components may wear out, shortening the engine's lifespan.

What to Pay Attention to When Driving in Deep Water

When driving through deep water, shift into a low gear, maintain steady throttle, and proceed slowly. If the car stalls during the process, occupants should exit the vehicle immediately and avoid attempting to restart the engine, as this can damage the engine. Additional tips: 1. Slow down or stop to observe: When encountering waterlogged roads, check if the water level reaches the bumper or two-thirds of the tire height. If the water level is high, try to detour instead of forcing your way through. 2. Avoid stopping, shifting gears, or releasing the throttle: Besides maintaining a low speed, try not to stop, shift gears, release the throttle, or accelerate. Instead, drive steadily at a low gear with moderate throttle. 3. Do not restart the engine if it stalls: Take measures to tow the car to a safe area with less water as soon as possible. Water entering the engine is a serious issue—it can pass through the air filter into the intake valve and then into the cylinder block. Never attempt to restart the engine in this situation, as it may cause critical components like the crankshaft and connecting rod to deform, leading to engine vibration or even component breakage.

Why Lift the Wipers in Snow?

The following are the reasons for lifting car wipers in snowy weather: 1. To protect the car wipers. In winter, temperatures are relatively low, and wipers are prone to freezing. Many people instinctively turn on the wipers, which can easily cause the motor to burn out. 2. To clean the windshield more effectively. After snow, wipers are prone to freezing together with the car windshield, requiring timely snow removal. Therefore, lifting the wipers in advance on snowy days reduces the difficulty of snow removal. Here are the correct methods for snow removal: 1. First, remove the snow from the windshield, then use the car's heater to defrost the windshield. 2. Turn the air conditioning to hot air and direct it toward the windshield. If the wipers are frozen, they can also be thawed while blowing air on the windshield. After removing all the ice and snow from the windshield, proceed with other operations.
