Waterproof and anti-biological exhaust cylinder

Abstract

The invention belongs to the field of automobile exhaust pipes, and particularly relates to a waterproof and anti-biological exhaust cylinder. The waterproof and anti-biological exhaust cylinder comprises an exhaust cylinder body, a silencer, three pressure dividing pipes, sliding plugs, screw rods, springs A, a ring sleeve C, L rods, conical plates, plate springs, guide rods, a ring sleeve D, connecting rods, a cover plate and springs B, wherein the three pressure dividing pipes are uniformly mounted on the exhaust cylinder body provided with the silencer in the circumferential direction, andthe pressure dividing pipes communicate with one end, close to an engine, of the exhaust cylinder body. According to the waterproof and anti-biological exhaust cylinder, under the combined action ofthe gas pressure of the engine entering the pressure dividing pipes and the springs A, the three screw rods drive the three conical plates which are combined into a complete conical barrel to be opened and closed through a series of transmission, it is guaranteed that the pressure of waste gas exhausted by the exhaust cylinder is kept balanced no matter the engine is oiled or deoiled, the water absorption phenomenon of the exhaust cylinder caused by acceleration and deceleration of an accelerator when an automobile passes through a road surface with much accumulated water is avoided, and damage to an oxygen sensor and reduction of exhaust efficiency due to corrosion caused by the fact that accumulated water in the exhaust cylinder cannot be drained in time are avoided.

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
