Abstract

This device is the attachment of internal-combustion engine purging system.

The problem that needs to solve is:

1. after machine started several minutes, the temperature in the smoke-eliminating silencer could raise, just can be with unburnt useless cigarette resume combustion.

2. owing to the transfer function of machine itself, internal-combustion engine is when work, and the impact noise that parts produced is also very big, to this noise, attachment is helpless, wants to address this problem, preferably make one and machine shape sound insulation shell of a size, internal-combustion engine is sealed.

This device major character is:

When noise and useless cigarette pass through this device, further consumed, decompose, prolong its process, and reach the outlet port, what just become is very little.

Description

Smoke-eliminating silencer for internal combustion engines

This device is the attachment of internal-combustion engine purging system.

It is made up of inlet, preceding catch, preceding metal noise reduction smoke elimination pipe, middle catch, intermediate metal noise reduction smoke elimination pipe, filter disc and outlet.

Its shell is a bimetallic strip, the high temperature resistant material of middle filling foam-like is formed, preceding catch and middle catch respectively have big holes, garden such as eight diameters and metal hush pipe, be used for installing four pairs of metal noise reductions smoke elimination pipes respectively, the metal tube sidewall is abound with the aperture that diameter is 1mm, and noise reduction eliminates smoke and manages the back is totally four of filter discs, its area equates with catch, the aperture that also is covered with diameter 1mm, the external chimney in outlet port, inlet is connected the exhaust ports of body cylinder.This device inlet and relief opening to be connected distance short more good more, but length no matter, its connecting tube is necessary for the pipeline of double-deck centre filling exotic material.

According to actual needs, this device specification is changeable, and shape can be made arbitrarily.

Its noise reduction principle:

Under the insulation effect of double-deck filling foam-like exotic material shell, when noise that is produced during machine works and exhaust fumes eliminate smoke pipe and filter disc by the metal noise reduction, temperature increases suddenly in the device because the high temperature of friction and useless cigarette makes, imperfect combustion so useless cigarette has just carried out a resume combustion, thereby reach the smoke elimination purpose, noise is by metal hush pipe and filter disc the time, owing to disperse the deadening of prolongation, friction and shell simultaneously, when exporting, what just become is very low little.

Its aufbauprinciple is as scheming:

Fig. 1: the organigram of this device, wherein A is the ingress; B is the outlet port; C is the shell of double-deck middle filling foam-like exotic material; D is preceding catch and middle catch; E is a filter disc; F is a metal noise reduction smoke elimination pipe.

Claims

The major character of this device is:

Under the insulation and deadening of the double casing of the high temperature resistant material of middle filling foam-like, sound and useless cigarette are by in the device time, and sound is produced dispersion, prolongs operation, hinders and transmits, and weakened gradually; Useless cigarette can fire again and reduce, and reaches the purpose of noise reduction and smoke elimination.

Protection domain:

The whole constituent element of this device and noise and the useless cigarette running principle in passing through device.

Claim:

1, the double casing of middle filling foam-like exotic material.
2, noise reduction smoke elimination metal tube.
3, filter disc.
