Abstract
The utility model discloses a novel exhausting pipeline for a motor, wherein the exhausting pipeline is composed of a set of exhaust manifolds connected in sequence, a corrugated pipe is arranged between every two exhaust manifolds, and each exhaust manifold is in connection with each corrugated pipe through a V-shaped clamp. The novel exhausting pipeline for the motor overcomes the shortcomings that thermal expansion of an exhausting pipeline of an existing motor can be produced due to high exhausting temperature, and thermal deformation, big pressure fluctuation and short service life of the exhausting pipeline can be easily caused. The novel exhausting pipeline for the motor has the advantages that expansion amount of the exhausting pipeline can be compensated, thermal deformation and big pressure fluctuation are avoided, and efficiency is improved.
Description
Technical field
The utility model belongs to the venting gas appliance field of motor, is specifically related to a kind of novel exhaust pipe for engine road.
Background technique
At present, exhaust-gas turbocharger on the motor, that the waste gas inertia impulsive force that utilizes motor to discharge promotes the interior turbine of turbine chamber, turbine drives again coaxial impeller, the air that the impeller force feed is sent here by the air-strainer pipeline, make it supercharging and enter cylinder, when engine speed speeds, the waste gas velocity of discharge and secondary speed also speed synchronously, impeller just compresses more air and enters cylinder, the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and adjust the rotating speed of motor, just can increase the output power of motor, exhaust duct one end is fixed on the cylinder head by flange and is connected with relief opening, the other end links to each other with the turbine case suction port of exhaust-gas turbocharger, what existing exhaust duct adopted is single exhaust duct, and single exhaust duct is because the temperature of waste gas, cause thermal expansion of pipeline, thereby cause exhaust duct easily to cause deformation fracture, in addition, the waveform that pressure wave forms during exhaust causes the fluctuation of outlet pipe internal pressure large, pressure wave disturbs normally carrying out of scavenging, caused the outlet pipe exhaust energy to lose, caused efficient low, working life is short.
The model utility content
The technical problems to be solved in the utility model is high because of delivery temperature for existing engine exhaust pipeline, produce thermal expansion, easily cause exhaust duct temperature distortion, pressure surge is large, working life is short defective, a kind of swell increment that compensates exhaust duct is provided, keep from heat distortion, pressure surge is large, a kind of novel exhaust pipe for engine road of raising the efficiency.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: a kind of novel exhaust pipe for engine road, and wherein, exhaust duct is connected to form successively by one group of gas exhaust manifold, be provided with bellows between each gas exhaust manifold, gas exhaust manifold and bellows are by the V-type clip connected.
Adopt a kind of novel exhaust pipe for engine road of technical solutions of the utility model, because exhaust duct is connected to form successively by one group of gas exhaust manifold, be provided with bellows between each gas exhaust manifold, gas exhaust manifold and bellows are by the V-type clip connected, pressure wave forms continuous waveform during exhaust, by the bellows interaction pressure wave wave amplitude is reduced, guarantee normally carrying out of scavenging, the exhaust energy restriction loss is reduced, in addition, bellows is the tubulose elastic sensing element that connects into along the folding retractable direction with collapsible wrinkle sheet, utilize auxiliary helical spring or reed to increase elasticity, therefore, bellows can compensate the swell increment of outlet pipe, realizes the free-extension that expands with heat and contract with cold, avoid expanding with heat and contract with cold and cause that exhaust duct is out of shape, break, gas exhaust manifold and bellows are by the V-type clip connected, and the setting of V-type clip avoids waste gas to overflow from the slit between gas exhaust manifold and the bellows, affects efficient.
Further, a kind of novel exhaust pipe for engine road is provided with seal ring between bellows and the gas exhaust manifold, for bellows and gas exhaust manifold are connected to form good the cooperation, guarantees sealing, avoids waste gas to leak.
Adopt a kind of novel exhaust pipe for engine road of technical solutions of the utility model, when waste gas enters exhaust duct, seal ring and V-type clip have guaranteed the sealing of joint, pressure wave is by gas exhaust manifold and bellows, at first because the scalability of bellows, bellows has compensated because the expansion that waste-gas heat produces, realize expanding with heat and contract with cold of exhaust duct, avoid causing the distortion of exhaust duct and breaking, in addition, pressure wave is through gas exhaust manifold and bellows, because the ripple of bellows is so that the pressure wave wave amplitude reduces, the assurance scavenging is normally carried out, and exhaust energy is fully used, improve working efficiency, prolonged working life.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is a kind of novel exhaust pipe for engine road embodiment's of the utility model schematic diagram.
Embodiment
As shown in Figure 1, a kind of novel exhaust pipe for engine road of the utility model, wherein, exhaust duct is connected to form successively by one group of gas exhaust manifold 2, is provided with bellows 1 between each gas exhaust manifold 2, and gas exhaust manifold 2 is connected by V-type clip 3 with bellows 1; Be provided with seal ring 4 between bellows 1 and the gas exhaust manifold 2.
In specific implementation process, waste gas enters exhaust duct, seal ring 4 and V-type clip 3 have guaranteed the sealing of joint, when the exhaust gas pressure ripple passes through gas exhaust manifold 2 and bellows 1, at first because the scalability of bellows 1, bellows 1 has compensated because the expansion that waste-gas heat produces, realize expanding with heat and contract with cold of exhaust duct, avoid causing the distortion of exhaust duct and breaking, in addition, pressure wave is through gas exhaust manifold 2 and bellows 1, because the ripple of bellows 1 is so that the pressure wave wave amplitude reduces, the assurance scavenging is normally carried out, and exhaust energy is fully used, improve working efficiency, prolonged working life.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. novel exhaust pipe for engine road, it is characterized in that: exhaust duct is connected to form successively by one group of gas exhaust manifold, is provided with bellows between each gas exhaust manifold, and gas exhaust manifold and bellows are by the V-type clip connected.
