The utility model has the advantages that the bypass exhaust pipe is arranged, and the requirement of the vehicle on noise during running under normal road conditions is ensured by controlling the opening and closing of the exhaust bypass valve in the bypass exhaust pipe; and when the vehicle runs under special road conditions, a part of exhaust gas discharged by the engine does not pass through the silencer device and is directly discharged into the atmosphere through the bypass exhaust pipe, so that the backpressure of the engine is effectively reduced, and the power utilization rate of the engine is improved.
Description
Technical field
The utility model relates to the automobile engine to exhaust device, relates in particular to the engine exhaust by-pass collar of limit-condition automobile.
Background technique
Existing automobile engine to exhaust device all is equipped with air exhaust muffler device in order to satisfy noise requirements, and the waste gas that motor is discharged enters atmosphere after all eliminating the noise by silencing apparatus.Can produce certain engine back pressure during waste gas process silencing apparatus, consume a part of engine power, the power of motor can not be utilized fully.The road conditions of mainly travelling of limit-condition automobile be desert, grassland and plateau etc. meagrely-populated, to the abominable location that noise not is not strict with, these abominable road conditions are had relatively high expectations to vehicle power, and are not high to noise requirements.When the vehicle of the existing automobile engine to exhaust device of equipment travelled under above-mentioned abominable road conditions, because the back pressure that produces in the noise elimination process has consumed the part engine power, the power that causes motor to produce descended the oil consumption height.
The model utility content
When being to discharge at engine exhaust, the purpose of this utility model produces the problem of back pressure consumption of engine power through silencing apparatus, a kind of engine exhaust by-pass collar is provided, making it can satisfy limit-condition automobile is having relatively high expectations to vehicle power, under the not high abominable road conditions travel situations of noise requirements, give full play to the power of motor.
For achieving the above object, the utility model adopts following technological scheme: the engine exhaust by-pass collar, it is characterized in that this device comprises the other bypass outlet pipe that is connected in the silencing apparatus front end engine exhaust pipe, in the bypass outlet pipe, be provided with the exhaust by-pass valve of control bypass outlet pipe break-make, and the valve operating mechanism of control exhaust by-pass valve valve opening and closing.
In such scheme, described exhaust by-pass valve is made of valve body, valve and valve hinges, and valve is on the valve hinges between valve body suction port and the air outlet, and valve hinges links to each other with the valve operating mechanism, and valve body is fixed on the bypass outlet pipe pipeline.
Above-mentioned valve body can be fixed on the flange 7, and flange 7 is connected with flange 6 on being fixed on the bypass outlet pipe.
In such scheme, described valve operating mechanism is by pedestal, cylinder block, piston, piston rod, piston reset spring, connecting rod and pivoted arm constitute, described pedestal is fixed on the valve body, the rear end of described cylinder block is hinged on the pedestal, the front end of piston rod stretches out and fixedlys connected with the rear end of connecting rod from the front end of cylinder block, the rear end of piston rod is fixed on the piston, described piston and piston reset spring are placed in the cylinder block, one end of described pivoted arm is fixedlyed connected with valve hinges, the other end of pivoted arm and the front end of connecting rod are hinged, and cylinder block links to each other with gas holder through control valve by pipeline.
Described control valve is manual one control air valve, and manually the one control air valve control knob is installed in operator cabin inside.
The utility model is divided into two outlet pipes with engine exhaust pipe segment distance behind engine body, fixes a silencer on the outlet pipe, above the other bypass outlet pipe exhaust by-pass valve is installed, and does not fix a silencer.When vehicle travels in the higher location of noise requirements, be installed in the manual one control air valve control knob of operator cabin inside by manipulation, close exhaust by-pass valve, the waste gas that motor is discharged is discharged through silencing apparatus, reduces the vehicle driving noise; When vehicle when travelled in the abominable location of noise no requirement (NR), be installed in the manual one control air valve control knob of operator cabin inside by manipulation, open exhaust by-pass valve; Allow most waste gas enter atmosphere, reduce the exhaust back pressure that produces because of silencer, the power of motor is utilized under this road conditions as much as possible, reduce unnecessary kinetic equation loss by the exhaust duct of no muffler.
The utility model is owing to be provided with the bypass outlet pipe, by handling opening and closing of exhaust by-pass valve in the bypass outlet pipe, both guaranteed when vehicle travels the requirement to noise under normal road conditions; When vehicle was travelled under special road conditions, a part of waste gas that motor is discharged directly entered atmosphere without muffler through the bypass outlet pipe, has reduced engine back pressure effectively, has improved the engine power utilization ratio.

Embodiment:
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described further.As Fig. 1, Fig. 2, shown in Figure 3, present embodiment comprises the other bypass outlet pipe 3 that is connected in the silencing apparatus 4 front end engine exhaust pipe 2, in bypass outlet pipe 3, be provided with the exhaust by-pass valve 5 of control bypass outlet pipe break-make, and the valve operating mechanism of control exhaust by-pass valve valve opening.
Exhaust by-pass valve 5 is connected with flange 6 usefulness bolts on being fixed on bypass outlet pipe 3 by the flange 7 that is fixed on the exhaust by-pass valve; Exhaust by-pass valve 5 is made up of valve body 10, valve 8 and valve hinges 9, and described valve body 10 has suction port 21 and air outlet 20, and valve 8 is fixed on the valve hinges 9 between suction port 21 and the air outlet 20.
Described valve body operating mechanism is made of cylinder block 15, piston 17, piston rod 16, piston reset spring 14, connecting rod 13 and pivoted arm 11 and pedestal 19.Pedestal 19 is fixed on the valve body 10, and the rear end of described cylinder block 15 is hinged on the pedestal 19 with bearing pin 18, and cylinder block 15 links to each other with gas holder through control valve by pipeline, and described control valve is manual one control air valve, and manually one control air valve is installed in operator cabin inside.Described piston 17 and piston reset spring 14 are placed in the cylinder block 15, and the rear end of piston rod 16 is fixed on the piston 17, and the front end of piston rod 16 stretches out and fixedlys connected with the rear end of connecting rod 13 from the front end of cylinder block 15.One end of described pivoted arm 11 is fixedlyed connected with valve hinges 9, and the front end of the other end of pivoted arm 11 and connecting rod 13 is hinged with bearing pin 12.
