A waterproof and anti-biological exhaust pipe

Abstract

The invention belongs to the field of automobile exhaust pipes, in particular to a waterproof and anti-biological exhaust pipe, which includes an exhaust pipe, a muffler, a pressure divider, a slide plug, a screw, a spring A, a ring sleeve C, an L rod, and a cone plate , leaf spring, guide rod, ring sleeve D, connecting rod, cover plate, spring B, in which three pressure divider tubes are evenly installed in the upper direction of the exhaust cylinder with the muffler installed, and the pressure divider tube and the exhaust cylinder are close to the engine One end of the screw is connected; the three screw rods in the present invention are driven by a series of transmissions under the joint action of the gas pressure of the engine entering the partial pressure pipe and the spring A to open and close the three cone plates that are formed into a complete conical cylinder in the merged state, ensuring that the Whether the engine is refueling or defueling, the pressure of the exhaust gas discharged from the exhaust pipe is kept balanced, so as to avoid the water absorption phenomenon of the exhaust pipe caused by the addition and subtraction of the throttle when the car passes through the road with a lot of water, and to avoid the accumulation of water in the exhaust pipe. Failure to discharge the corrosion in time will result in damage to the oxygen sensor and reduction in exhaust efficiency.

Description

technical field [0001] The invention belongs to the field of automobile exhaust pipes, in particular to a waterproof and anti-biological exhaust pipe. Background technique [0002] The automobile exhaust pipe is the main part of the automobile, which is mainly responsible for discharging the exhaust gas produced by the automobile engine and improving the efficiency of the engine. [0003] In heavy rain, due to the deep water on the road surface, the exhaust pipe may be submerged when the car passes through water. At this time, the large or small exhaust pressure of the exhaust pipe caused by the switch of the throttle of the car will cause rainwater to be sucked or flushed into the exhaust pipe. If the inhaled or flushed rainwater cannot be drained in time, it will stay in the exhaust pipe for a long time In the gas cylinder, plus a lot of gasoline contains sulfur, which will cause serious corrosion of the exhaust cylinder and affect the exhaust efficiency of the exhaust cy...

AI Technical Summary

Problems solved by technology

At this time, the large or small exhaust pressure of the exhaust pipe caused by the switch of the throttle of the car will cause rainwater to be sucked or flushed into the exhaust pipe. If the inhaled or flushed rainwater cannot be drained in time, it will stay in the exhaust pipe for a long time In the gas cylinder, plus a lot of gasoline contains sulfur, which will cause serious corrosion of the exhaust cylinder and affect the exhaust efficiency of the exhaust cylinder

At the same time, too much water in the exhaust pipe will damage the oxygen sensor in the three-way catalytic converter, thereby affecting the air-fuel ratio of the engine and reducing engine efficiency
