Is it normal for the tenth generation accord to make a deep voice?

Not normal. According to the inquiry of Guangqi Honda official website, the muffled sound of 10 Accord is due to serious carbon deposition. By controlling the throttle opening of the carburetor, the filling quantity of the cylinder and the metered fuel flow of the fuel regulator, the output power of the engine is determined, so that the engine can generate thrust and avoid abnormal noise caused by excessive carbon deposition. The 10th generation Accord 20 18 went on the market, with brand-new design and modeling, and the overall visual experience was younger and more energetic.
