Abstract

The utility model relates to a power boosting fuel-saving silencer for motor vehicles. The silencer comprises an air inlet pipe (1), an air outlet pipe (6), a casing (3) and closing caps (2) on both ends of the casing, wherein, horn-shaped power boosting sleeves (4) are alternately arranged in the casing (3), and the peripheral walls of the horn-shaped power boosting sleeves (4) are provided with micropores (5) to form a structure with the characteristics of fast reduction of discharge pressure, smooth discharging, multi-stage penetrated friction, noise reduction and sound absorption. The utility model has the characteristics of simple structure, no special requirement to installation and use, easy synchronous realization of the requirements of power boosting, fuel saving, noise reduction and sound absorption, extended service life of an engine, etc. Proved by actual measurement, the fuel saving ratio of the motor vehicles can be from 12% to 30%; the engine can keep normal operating temperature, and the power can be obviously increased.

Description

Motor Vehicle reinforcing and oil-saving silencing apparatus

The utility model relates to a kind of Motor Vehicle silencing apparatus, especially Motor Vehicle reinforcing and oil-saving silencing apparatus.

The Motor Vehicle silencing apparatus generally is that the capping by suction tude, steam outlet pipe, housing and two ends thereof forms external form, and in housing, be provided with the I chamber that one section center siphunculus and a slice dividing plate are divided into successively at least, another sheet dividing plate and one section off-centre or center siphunculus are divided into the III chamber, be the II chamber between two dividing plates, and the tube wall of dividing plate and siphunculus is evenly equipped with micropore, formation filtering type noise elimination exhaust structure (as the Santana car silencing apparatus of Shanghai Volkswagen Automotive Co., Ltd production).But this structure has such problem, in use for some time, the micropore of dividing plate and sleeve pipe all can have obstruction in various degree, gently then the suction tude flange dash take off or usually cause engine operating temperature to raise fast when running at high speed, fan blade does not change, power reduces, thereby aggravation cylinder wear and increase oil consumption etc.

For addressing this problem.The Chinese patent CN96237522 that the Japanese plum base application of hundred million auto parts machinery factories is pacified Heshan City in Guangdong Province propose between motor and the silencing apparatus socket air entraining pipe identical with cylinder block gas port quantity, in establish the additional devices such as horn-like sleeve, bend connector of flow-limiting valve, can alleviate micropore chocking-up degree in the silencing apparatus, and make waste gas do secondary combustion once more, play certain Synergistic and energy-saving effect.But for the Motor Vehicle of having finalized the design, be difficult to implement this scheme, because accelerate the drainage exhaust velocity, simple possible on the one side claimed structure, because Motor Vehicle is usually worked, require to realize synchronously that noise reduction is eliminated the noise and very big difficulty will take place Synergistic and energy-saving on the other hand under different speed, the gradient and load.

The purpose of this utility model provides a kind of improved Motor Vehicle reinforcing and oil-saving silencing apparatus, it can be under the prerequisite that keeps original noise reduction to eliminate the noise simplified construction, thereby realize the reinforcing and oil-saving of Motor Vehicle effectively.

The purpose of this utility model realizes like this: the compartment of terrain is provided with the tubaeform noise elimination power-assisted cover that perisporium all has micropore in the housing of silencing apparatus, should the noise elimination power-assisted overlap the toy trumpet mouth towards airintake direction, the typhon mouth forms exhaust pressure and reduces soon, discharges unimpeded, the multistage structure that friction absorbs the air-flow voice that penetrates towards outgassing direction.

The utility model is because only need be provided with tubaeform noise elimination power-assisted cover at interval in single ground, so structure is simple especially in original suppressor case; Do not lie in the external form structure that changes silencing apparatus or add device owing to the starting point simultaneously, so its installing and using the same type machine motor-car without any special requirement; Owing to be straight-through type exhaust and multistage expansion step-down cooling to giving vent to anger,, also can prolong the working life of motor in addition so realize the requirement that reinforcing and oil-saving and noise reduction are eliminated the noise easily from air inlet.Survey factually and show: the motor car fuel-saving rate is 12-30%, and motor keeps normal working temperature, and power obviously improves.The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof:

Fig. 1 is the schematic representation according to the Motor Vehicle reinforcing and oil-saving silencing apparatus that the utility model proposes.

Fig. 2 is the tubaeform noise elimination power-assisted cover sectional view according to the Motor Vehicle reinforcing and oil-saving silencing apparatus that the utility model proposes.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete silencing apparatus that the utility model proposes.

This silencing apparatus comprises two cappings [2] at a suction tude [1], a steam outlet pipe [6], a housing [3] and two ends thereof.The interior compartment of terrain of housing [3] is provided with the tubaeform noise elimination power-assisted cover [5] that perisporium is all opened micropore [4].The toy trumpet mouth of tubaeform noise elimination power-assisted cover [5] is towards airintake direction, and the typhon mouth is towards outgassing direction and be fixed on housing [3] inwall edge.

Along the direction of arrow through suction tude [1] in housing [3] during exhaust, part air-flow directly enters from the toy trumpet mouth of the tubaeform noise elimination power-assisted cover [5] in a chamber and is expanded to next chamber, another part air-flow then penetrates friction from the micropore [4] of tubaeform noise elimination power-assisted cover [5] perisporium, the turbulent flow that accomplishes, the decompression of one-level level noise reduction passes straight through to steam outlet pipe [6] and discharges according to this.The semi-cone angle α of tubaeform noise elimination power-assisted cover [5] is preferably between 30 °-60 ° to improve the effect of noise reduction sound-absorbing and step-down; The internal diameter of its toy trumpet mouth should be consistent with the internal diameter of suction tude [1] or steam outlet pipe [6], looses warm unimpeded to guarantee exhaust.According to the motor engine exhaust gas amount, select to be arranged at the interior 3-10 of housing [3] tubaeform noise elimination power-assisted cover [5], air displacement is big more, and number is many more, otherwise, then few.In addition, tubaeform noise elimination power-assisted cover [5] and the same shape of housing [3] are made circle or ellipse etc.
