Abstract

The invention provides an adjustable diesel engine exhaust pipe connecting device. The adjustable diesel engine exhaust pipe connecting device comprises a lining pipe, a corrugated pipe and a clamp. The two ends of the lining pipe are of a spherical structure. The spherical structures of the two ends of the lining pipe are connected to a first exhaust pipe connector and a second exhaust pipe connector correspondingly. The corrugated pipe is connected between the outer portions of the first exhaust pipe connector and the second exhaust pipe connector and fixed through the clamp. According to the adjustable diesel engine exhaust pipe connecting device, flexible exhaust pipeline connection is achieved, the purpose of adjustable assembling is achieved, and the design tolerance and the processing and manufacturing error are effectively offset; and the sealing reliability of an exhaust system is improved, the air leakage probability of an engine is reduced, exhaust energy losses of a flow guiding barrel are effectively avoided through the lining pipe of the spherical structure, and the energy utilization rate is increased.

Description

technical field

[0001] The invention belongs to the technical field of engines, and in particular relates to an adjustable diesel engine exhaust pipe connection device. Background technique

[0002] For multi-cylinder V-type engines, especially those with more than 8 cylinders, the exhaust pipe often adopts a segmented structure. This is because the exhaust pipe mostly adopts casting technology, and traditional casting has the defect of large dimensional error. The air pipe is adjustable to make up for the error caused by the process. At the same time, as an engine peripheral part, the exhaust pipe is installed relatively late in the assembly of the whole machine, and the problems of assembly over-positioning and tolerance accumulation are more prominent. Therefore, an adjustable structure needs to be applied between the pipes to ensure good assemblability and To meet the sealing problem between parts.
