Embodiment approach

[0042] Such as Figure 11 :

[0043] 1. When the engine exhaust gas is discharged ( Figure 11 10 and 11 in the example), directly hitting the wind rotor blades with a certain twist angle to drive the wind rotor blades to rotate, directly plays a significant effect of comprehensive noise reduction of anti-elimination and resistance elimination.

[0044] 2. When one or more groups of through-holes on the wind rotor blades work continuously, the exhaust gas flow produces a Helmholm resonance effect in this confined space, which has the effect of shock absorption, noise reduction and energy saving.

[0045] 3. Helmholtz resonance principle explains Helmholtz resonator "Resonance tube" is a general term for Helmholtz resonators (it is named after Herman von Helmholtz (1821-1894), an authoritative scientist in this field Its name. Its design principle is very simple. A large box with a small opening will resonate at a certain frequency. Multi-stroke engines also produce sound wav...

Abstract

The invention provides an energy-saving silencer, and relates to the technical field of silencers. The silencer comprises a silencer housing and a silencing core arranged in the silencer housing, wherein the silencing core comprises a wind power generator, wind wheel blades of the wind power generator naturally form spoilers, the spoilers are sleeved on a transmission shaft of the wind power generator in a penetrating way to drive the wind power generator to rotate so as to generate electricity. The silencing core, i.e., the wind power generator can directly transmit power to accumulator batteries through a power cord. In the silencer provided by the invention, the silencing core is composed of a plurality of elongated spoilers which are provided with vent holes and are sleeved on the transmission shaft of the wind power generator in a penetrating way, i.e., the wind wheel blades of the wind power generator, exhaust gas is eliminated by sequentially passing through the vent holes of the spoilers, noise generated by exhaust gas can be effectively reduced, and the silencing effect is obvious. The energy-saving silencer has the advantages of small structure, simplicity in manufacture and convenience for disassembly, cleaning and maintenance, not only has silencing and noise reduction functions, but also can generate electricity and provide electric energy. The silencer not only can be used on an exhaust pipe of an engine of an automotive vehicle, but also can be used on exhaust pipes of other internal combustion engines, boilers, tractors, internal-combustion electric generators, aerodynamic equipment, and the like.

Description

technical field [0001] The invention relates to a muffler which is used together with an internal combustion engine and an aerodynamic device. Its technology skillfully combines the impedance composite noise reduction principle with the Helmholtz resonance principle, and is innovatively linked with a generator for application. Background technique [0002] Since the birth of the internal combustion engine, so have the muffler. Relevant technologies are constantly updated. At present, typical noise reduction technologies include resistive noise reduction technology, resistive noise reduction technology, Hollmholtz noise reduction technology, active noise reduction technology and so on. [0003] The so-called resistive muffler mainly uses sound-absorbing materials to reduce noise, and the sound-absorbing materials are fixed on the inner wall of the pipeline where the air flow circulates or arranged in a certain way in the pipeline. When the sound wave enters the muffler, most...
