Structure of engine exhauster

Abstract

A structure of engine exhauster includes a front case, a board and a rear case. The front case has an opening and the rear case has a hole. Exhaust gas passes through the board combined between the front case and the rear case. A bending part is disposed in the board. An opening is disposed on the bending part. A beehive portion is disposed above the bending part for exhausting the exhaust gas. A check valve is disposed in the front case for entering unidirectional secondary air. Whereby, the exhaust gas from the front case is mixed up with the secondary air from the check valve of the front case, and then is exhausted from the hole of the rear case via the beehive portion of the board for further reducing air pollution.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a structure of engine exhauster, installing a board between front and rear case of the association when exhaust gas passes, according to Bernoulli Theorem to generate pressure differences. A check valve is disposed at the largest point of pressure difference allowing secondary air to enter from the front case of check valve and mix with exhaust gas, then gas through the honeycomb structure of the catalytic to increase catalytic efficiency, this air-gas mixture is then exhaust through holes on the rear case. This important design is to provide advantage of fast and significant air pollution reduction performance, this important engine exhauster is suitable and idea use with all gasoline-engines type gardening equipment or similar equipment. BACKGROUND OF THE INVENTION [0002] In General, the engine exhauster is the most widely used have been broadly used, users and manufacturers attach great importance to application of en...

AI Technical Summary

Benefits of technology

"The present invention provides an engine exhaust structure that uses a board to create a pressure difference between the front and rear cases, which helps to reduce air pollution. A check valve is placed at the location with the highest pressure difference to allow secondary air to enter the system and increase catalytic efficiency. The air is then exhaled from holes in the rear case, resulting in a firm combination and significant air pollution reduction. Overall, this structure improves engine performance and reduces harmful emissions."

Problems solved by technology

However, although noise is eliminated, air exhausted is still exhaust gas.

The air pollution issue is not improved yet.
