Automobile exhaust emission pipe

Abstract

The invention discloses an automobile exhaust emission pipe. The automobile exhaust emission pipe comprises an exhaust main pipe and a silencing pipe arranged on the exhaust main pipe, wherein the silencing pipe is transversely arranged; an upper partition plate and a lower partition plate are arranged in the silencing pipe; the top of the upper partition plate is fixedly connected to the inner top wall of the silencing pipe; the bottom of the upper partition plate is suspended; a first silencing cavity is defined between the left side of the upper partition plate and the left end of the silencing pipe; the bottom of the lower partition plate is fixedly connected to the inner bottom wall of the silencing pipe; the lower top of the lower partition plate is suspended; a second silencing cavity is defined between the left side of the lower partition plate and the right side of the upper partition plate; a third silencing cavity is defined between the right side of the lower partition plate and the right end of the silencing pipe; a lower notch is formed between the bottom of the upper partition plate and the bottom wall of the silencing pipe; an upper notch is formed between the top of the lower partition plate and the top wall of the silencing pipe; the first silencing cavity and the second silencing cavity are communicated through the lower notch; and the third silencing cavityand the second silencing cavity communicate through the upper notch. In the abovementioned way, after exhaust passes through the first silencing cavity, the second silencing cavity and the third silencing cavity, noise mixed in the exhaust can be greatly lowered.
