What does car exhaust resonance feel like?

Car exhaust resonance feels like the vehicle's floor is vibrating, accompanied by some buzzing sounds. Exhaust resonance can significantly affect the comfort of the vehicle. Most factory-installed exhaust systems do not exhibit resonance; this phenomenon is usually found in aftermarket or modified exhaust systems. Modifying the exhaust header can enhance performance, especially for turbocharged engines, where the performance improvement is quite noticeable. The exhaust header contains a component called the catalytic converter, which reduces the levels of pollutants in the exhaust gases. Other causes of exhaust resonance include vibrations generated by the engine. Typically, bellows are installed in the front and middle sections of the exhaust system. With proper design, these can effectively reduce most of the exhaust vibrations, but some residual vibrations may still remain inside the vehicle.

What is the purpose of alternating between high and low beams?

Alternating between high and low beams is used for nighttime encounters with oncoming vehicles, overtaking, etc. The purpose of switching between high and low beams is to serve as a warning. Below are additional details: 1. High beams: Should be turned on in conditions of poor visibility, such as on highways or rural roads. 2. Low beams: Should be used when visibility is good, as well as when encountering oncoming vehicles, following another vehicle, encountering pedestrians, or non-motorized vehicles. 3. Alternating beams: When overtaking large trucks, because they have large blind spots and high chassis, it is necessary to repeatedly flash the lights to alert the truck driver and ensure safety before overtaking.

Why is there no sound when playing songs after successful Bluetooth connection in Cruze?

In this case, re-pairing is required. The reason is that an abnormality occurred during the pairing process, which is not considered a fault issue. Before re-pairing, you need to turn off and then restart your phone, and also turn off and restart the vehicle's multimedia system to resolve this issue. Relevant information about in-car Bluetooth is as follows: 1. Function: After successful Bluetooth pairing, you can use your phone to play audio files or answer calls, which is very convenient. While driving, it ensures driving safety. Once the car's system and Bluetooth are connected, you can make calls directly through the car's system in hands-free mode. 2. Automatic connection: Once your phone and car system are connected, they will automatically connect the next time you use them, provided that your phone's Bluetooth is turned on. This eliminates the need for frequent manual connections, saving time and adding convenience to vehicle use. However, when using Bluetooth calls, privacy should be taken into consideration.

What brand is the engine of Hanteng Motors?

The engine of Hanteng Motors is produced by Jiangxi Tenle Power, so it belongs to domestic engines. Different models of Hanteng Motors have different engine models. The engine model of Hanteng X5 is TLE4G15D, with a maximum horsepower of 156, a maximum power of 115KW, a maximum power speed of 5600rpm, and a maximum torque of 215N.m. The engine model of Hanteng X7 new energy is TN4G18T, with a maximum horsepower of 170, a maximum power of 125KW, a maximum power speed of 2000-5800rpm, and a maximum torque of 245N.m. The engine of Hanteng Motors can be maintained daily by the following methods: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust system and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, and the selection standard should not be lower than the requirements specified by the manufacturer. Change the oil and filter regularly. The oil quality of any grade of lubricating oil will change during use. After a certain mileage, the performance will deteriorate, causing various problems for the engine. To avoid failures, the oil should be changed regularly according to the usage conditions, and the oil volume should be moderate. When the oil passes through the fine holes of the filter, the solid particles and sticky substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element will burst or the safety valve will open, allowing the oil to pass through the bypass valve and bring dirt back to the lubrication part, accelerating engine wear and increasing internal pollution. Clean the crankcase regularly. During engine operation, high-pressure unburned gas, acid, water, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing with metal powder generated by part wear to form sludge. When the amount is small, it is suspended in the oil; when the amount is large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Use a radiator cleaner to clean the radiator regularly. Removing rust and scale can not only ensure the normal operation of the engine but also extend the overall life of the radiator and the engine.
