Description

Technical Field

[0001] The utility model relates to the technical field of automobile exhaust pipes, in particular to an automobile exhaust pipe with a tail gas purification function. Background Technique

[0002] With the development of society, automobiles have gradually entered ordinary families. However, the tail gas emitted by automobiles contains three harmful gases, namely CO, hydrocarbons and nitrogen oxides, which seriously pollute the air. Therefore, automobiles are gradually improved during manufacturing, and an exhaust pipe purification device for eliminating harmful gases in the tail gas is developed.

[0003] The prior art (publication number: CN219101449U) discloses an automobile exhaust pipe with a tail gas purification function, including a shell, the shell includes an outer shell, and an inner shell is arranged inside the outer shell, and the outer shell is used to protect the inner shell; a purification component, the purification component is installed inside the shell and is used for purifying the tail gas; the shell also includes a gas collecting hood, the gas collecting hood is fixedly installed at the left and right ends of the inner shell, an air inlet pipe is arranged at the left end of the left gas collecting hood, and an exhaust pipe is arranged at the right end of the right gas collecting hood. The beneficial effect of the utility model lies in that: by arranging a second air inlet pipe, a certain amount of air can be injected into the tail gas, and a flow dividing plate is used to mix the tail gas and the air. Under the idle state, a heating wire is used to heat the mixed gas so that the temperature of the mixed gas reaches the optimal working temperature of the three-way catalytic converter. The O2 in the air reacts with the C in the tail gas to convert the carbon deposit into CO and CO2, avoiding the carbon deposit from blocking the catalyst core. After the engine speed is increased, a cooling pipe can be used to cool the inner shell to avoid damage to the catalyst core due to excessive temperature.
