Abstract
The utility model discloses an upright internal combustion engine exhaust silencer, comprising a silencer housing with a gas inlet pipe and a gas outlet pipe, and a core body arranged in the silencer housing; the gas outlet pipes of the silencer housing are combined as a whole with the silencing cavity through a streamline transition surface. Thanks to the technical characteristics that the gas inlet and the gas outlet pipe of the silencer housing are combined as a whole with the silencing cavity through a streamline transition surface, the utility model has the advantages of greatly improving the fatigue strength at the joint of the gas inlet and outlet pipes and the silencing cavity, consequently prolonging the service life of the utility model and reducing the running maintenance cost of the internal combustion engine.
Description
Technical field:
The utility model relates to a kind of exhaust muffler for internal combustion engine, especially relates to a kind of vertical exhaust muffler for internal combustion engine.
Background technique:
The existing structure that is used for the vertical exhaust muffler for internal combustion engine is muffler shell and the noise reduction core body that sets within it.Air inlet/outlet on the muffler shell is that two vertical surfaces combine by welding with the combination of noise reduction chamber.Because this baffler is vertically arranged in use, the vibration of sound wave baffler that air-flow causes during work, make described two vertical surface junctions easily produce metal fatigue point and damage, not only influenced erasure effect, and the working life of having reduced this baffler, increased the operating cost of internal-combustion engine.
The model utility content:
The purpose of the utility model is to provide a kind of vertical exhaust muffler for internal combustion engine at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can take following technical proposals to realize:
The utility model comprises the silencer casing that has the inlet, outlet mouth of pipe, is arranged on the core body in the described silencer casing, and the air inlet mouth of pipe and the noise reduction chamber of described silencer casing are combined as a whole by streamlined transitional surface.
The give vent to anger mouth of pipe and the noise reduction chamber of described silencer casing are combined as a whole by streamlined transitional surface.
Advantage of the present utility model just is to adopt with the inlet, outlet mouth of pipe of silencer casing and noise reduction chamber by streamlined transitional surface this technical characteristics that is combined as a whole, this has just improved the fatigue strength of the described inlet, outlet mouth of pipe and noise reduction chamber junction widely, thereby prolonged working life of the present utility model, reduced the operating maintenance expense of internal-combustion engine.
Description of drawings:
Fig. 1 cuts open figure for master of the present utility model.
Embodiment:
As shown in the figure, the utility model comprises the silencer casing 3 that has the inlet, outlet mouth of pipe 1,2, be arranged on the core body 4 in the described silencer casing 3, the inlet, outlet mouth of pipe 1,2 and the noise reduction chamber 5 of described silencer casing 3 are combined as a whole by streamlined transitional surface 6.
