Description

Supercharger front connecting pipe for diesel engine

Technical Field

The utility model relates to a take over before booster for diesel engine, mainly used engine technical field.

Background

In the working process of the diesel engine, tail gas exhausted by different cylinders is guided into an exhaust end of a supercharger, and generally, in the process of guiding the exhaust gas into the exhaust end of the supercharger, the energy loss of the exhaust gas is large, and the exhaust gas is limited by compact structure, so that the air flow loss of the exhaust gas is very large, and the structure is not attractive and compact.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: a supercharger front connection pipe for a diesel engine, which can effectively reduce the loss of exhaust energy and has a compact structure.

Take over before booster for diesel engine, including booster connecting plate and air flue connecting plate, set up the booster connector on the booster connecting plate, set up two air flue connectors on the air flue connecting plate, two air flue connectors set up side by side, set up the connecting pipe between booster connector and the two air flue connectors respectively, the inside intercommunication of two connecting pipes, intercommunication department is close to booster and links the interface end.

The two connecting pipes are respectively a first connecting pipe and a second connecting pipe, one end of the second connecting pipe is connected with the air passage connector, and the other end of the second connecting pipe is connected with the first connecting pipe.

The joint of the two connecting pipes is of an arc structure.

The corner positions of the two connecting pipes are arc-shaped.

The supercharger connecting plate and the air passage connecting plate are provided with connecting holes, and the connecting holes are respectively positioned on the peripheries of the supercharger connecting port and the air passage connecting port.

The connecting holes on the peripheries of the supercharger connecting port and the two air passage connecting ports are four.

Based on the condition of prior art, combine current diesel engine structural feature, the structure of taking over before the analysis former booster, optimize the pipeline structure of taking over before the booster, the existence of the inside turning of minimize air flue, all adopt the circular arc to replace sharp before, the merging position of two air flues is optimized, avoids the mutual interference of air current.

The utility model discloses merge into a set of air current two sets ofly by different cylinder combustion gas through mild air flue, during the leading-in booster that advances the diesel engine, can reduce air current energy loss's design principle as far as possible under, guaranteed the compactedness of structure. The novel supercharger front connecting pipe is arranged between the supercharger and the exhaust pipe, and other original structures of the diesel engine are unchanged.

The utility model has the advantages that:

this take over before supercharger for diesel engine not only can lead to the booster smoothly with the tail gas that different cylinders produced, still has compact structure, small in size's characteristics for exhaust air flow is more smooth, and the appearance is pleasing to the eye, compact structure, and the air current is smooth-going, avoids the air current of two air flues to produce and interferes.

Detailed Description

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1-5, diesel engine is with taking over before booster, including booster connecting plate 2 and air flue connecting plate 4, set up booster connector 1 on the booster connecting plate 2, set up two air flue connectors on the air flue connecting plate 4, two air flue connectors set up side by side, set up the connecting pipe between booster connector 1 and the two air flue connectors respectively, the inside intercommunication of two connecting pipes, the intercommunication department is close to booster connector 1 end. The two connecting pipes are respectively a first connecting pipe 3 and a second connecting pipe 5, one end of the second connecting pipe 5 is connected with the air passage connector, and the other end of the second connecting pipe is connected with the first connecting pipe 3. The joint of the two connecting pipes is of an arc structure. The corner positions of the two connecting pipes are arc-shaped. All set up connecting hole 6 on booster connecting plate 2 and the gas circuit connecting plate 4, connecting hole 6 is located the periphery of booster connector 1 and gas circuit connector respectively. The connecting holes 6 on the peripheries of the supercharger connecting port 1 and the two air passage connecting ports are four.

During the use, booster connecting plate 2 connects the booster, and diesel engine exhaust port department is connected to air flue connecting plate 4, with the smooth leading-in booster of tail gas that two cylinders produced. The compactness of the structure is ensured under the design principle that the energy loss of the airflow can be reduced as much as possible. The novel supercharger front connecting pipe is arranged between the supercharger and the exhaust pipe, and other original structures of the diesel engine are unchanged.
