European Lion generator welding machine can use 190A-250A power generation welding unit to weld 4.0 electrodes. Generally, normal welding 190A 3.2mm, spot welding 4.0mm; spot welding Welding 5.0mm welding rod; power generation welding machine is divided into two types: gasoline and diesel.
It is not accurate to judge the quality of the engine by the sound of the engine, and the car owner should use other reference means to judge the performance of the engine through the sound. Unless there is an abnormal noise, it means that the vehicle's engine may have defects and its performance is not particularly perfect.
The engine sounds of different vehicles are louder and quieter, and the types of sounds are also different. When evaluating vehicle performance using engine noise, someCar owners judge only by the loudness of the sound. This approach is not at all scientific.
For example, the engine noise is relatively loud. This phenomenon cannot indicate vehicle performance.
For some good cars, their own performance is significantly better, but their sound is relatively loud. Of course, it is also possible that they have undergone special tuning to deliberately amplify the vehicle's sound. the engine, so we cannot say that the performance of these cars is bad just by having a noisy engine.
The noise of the same engine is relatively low. On the one hand, the vehicle can be modified and adjusted in this way, vehicle friction can be minimized and parts can be adjusted accordingly. better fit. At this time, the engine performance is significantly better and the engine sound will be lower.
In another situationn, the original performance of the motor itself is not particularly good, but it can also reduce the motor noise to a very low level. In this case, the sound insulation effect of the motor can be improved. At this point, even if the vehicle noise is relatively loud, the owner still cannot hear it without opening the hood, so he cannot prove that the vehicle's performance is better.
