Abstract
The utility model relates to a using accessory of a silencer for an engine, in particular to a clapboard for a silencer for a power engine. The clapboard comprises a clapboard body, an air inlet and an air outlet which are formed on the clapboard body and an exhaust pipe which is communicated with the air outlet, wherein the exhaust pipe is provided with an arc-shaped section for prolonging the time of air flow whirl; and the air inlet is smaller than the air outlet; an air inlet of the exhaust pipe, which is smaller than the air outlet, is formed at the air inlet end of the exhaust pipe and is communicated with the air outlet by a backflow cavity of the silencer. Due to the adoption of the structure, the clapboard has the advantages of reducing the temperature of an exhaust port and reducing noise along with energy conservation and environment friendliness.
Description
Technical field
The utility model relates to the use accessory of motor with baffler, specifically is that a kind of power engine baffler that reduces relief opening temperature and energy-conserving and environment-protective is used dividing plate.
Technical background
In existing technical field of engines, baffler generally is installed is reduced noise, improve engine power and play effect in energy saving and environmental protection.But can existing motor silencer central diaphragm be to discharge tail gas temperature in the baffler and play conclusive effect through EPA (EPA refers to Environmental Protection Agency) authentication emission request; The dividing plate of existing technology is that an outlet pipe is set on partition body; On the outlet pipe of inlet end, offer inlet hole; High-temperature tail gas waiting time in baffler that the dividing plate of this structure makes motor discharge is shorter; Wherein harmful carbon monoxide and carbon dioxide can't fully reflect, can't reach the emission request of EPA authentication, and owing to high-temperature tail gas waiting time in baffler of motor discharge is shorter; So the EGT of discharging through the relief opening of outlet pipe is easy to take place the scald accident just than higher; And reduced engine power.
In sum, the dividing plate of existing technology makes the relief opening temperature high, the big and not environmental protection of energy consumption.
Summary of the invention
The purpose of the utility model provides a kind of power engine baffler that reduces relief opening temperature and energy-conserving and environment-protective and uses dividing plate.
For realizing that the technological scheme that the utility model purpose adopts is: a kind of power engine baffler is used dividing plate, the outlet pipe that comprises partition body, is arranged on suction port and the air outlet on the partition body and communicates with the air outlet; Wherein: said outlet pipe has increases the circle round arcuate segment of time of air-flow, and said suction port is less than the air outlet.The inlet end of said outlet pipe is provided with the outlet pipe suction port less than the air outlet, and the outlet pipe suction port is communicated with the air outlet through the baffler refluxing chamber.
Because said structure, the utility model has reduced the relief opening temperature, has further improved engine power, has also just reached energy-conservation purpose; CO, CO
2And other harmful gas time lengthening in outlet pipe and baffler refluxing chamber, fully reaction back discharging, but reaching the EPA emission request, this just is beneficial to environmental protection, the noise that reduces simultaneously more.
Description of drawings
The device of the utility model can further specify through the indefiniteness embodiment that accompanying drawing provides.
Accompanying drawing 1 is the structural representation of the utility model.
Accompanying drawing 2 is the rear view of accompanying drawing 1.
Accompanying drawing 3 is the right elevation of accompanying drawing 1.
Among the figure: 1, partition body; 2, suction port; 3, air outlet; 4, outlet pipe; 5, arcuate segment; 6, outlet pipe suction port; 7, exhaust outlet.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to accompanying drawing 1,2 and 3, the power engine baffler in the accompanying drawing is used dividing plate, the outlet pipe 4 that comprises partition body 1, is arranged on suction port 2 and the air outlet 3 on the partition body 1 and communicates with air outlet 3; Wherein: said outlet pipe 4 has increases the circle round arcuate segment 5 of time of air-flow, and said suction port 2 is less than air outlet 3.In the using process, increase the circle round arcuate segment 5 of time of air-flow, make CO, CO because outlet pipe 4 has
2And other harmful gas time lengthening in outlet pipe 4 and baffler refluxing chamber, reduced the temperature of gas when making its abundant sufficient reacting, also just reduced the temperature of outlet pipe 4 exhaust outlets 7.
For further improving CO, CO
2And the reflux time of other harmful gas in the baffler refluxing chamber, in the foregoing description: the inlet end of said outlet pipe 4 is provided with the outlet pipe suction port 6 less than air outlet 3, and outlet pipe suction port 6 is communicated with air outlet 3 through the baffler refluxing chamber.
In sum, this structure has reduced relief opening temperature and energy-conserving and environment-protective.
