Connecting and mounting structure of diesel engine and matched TPR61 supercharger

Abstract

The invention provides a connecting and mounting structure of a diesel engine and a matched TPR61 supercharger. The connecting and mounting structure comprises a supercharger support fixedly connectedwith a diesel engine shell and used for fixedly supporting the TPR61 supercharger. A waste gas inlet and an exhaust manifold of the TPR61 supercharger are connected through a corrugated connecting pipe. A waste gas outlet of the TPR61 supercharger is connected with an upper circular and lower square variable diameter pipe. An air outlet of the TPR61 supercharger is connected with an air cooler through an air connecting pipe. A lubricating oil inlet of the TPR61 supercharger is connected with an oil outlet of a lubricating oil filter through a lubricating oil inlet pipe. A lubricating oil outlet of the TPR61 supercharger is connected with an oil inlet of the lubricating oil filter through a lubricating oil return pipe. The TPR61 supercharger is not provided with a cooling water pipe. According to the connecting and mounting structure, by making an improvement on an exhaust system, a TPR61 supercharger oil inlet and return pipe system, the overall dimensions, external interfaces and thelike, the TPR61 supercharger is successfully assembled to the diesel engine. Under the condition of ensuring that the whole engine performance level is not lower than original indexes, the environmental adaptability of the diesel engine is improved.

Description

technical field [0001] The invention belongs to the technical field of connection between a diesel engine and a supercharger, and in particular relates to a connection installation structure for a diesel engine matching a TPR61 supercharger. Background technique [0002] The 16PA6V-280STC diesel engine is developed locally, and now the patented VTC304 supercharger (domestic model JT304) is used. The VTC304 supercharger switching point is determined according to the propeller characteristic line, and has not been verified under the external characteristics. During the actual ship operation, the operating area of ​​the diesel engine will exceed the propeller characteristic line. Advanced problems lead to multiple revisions of the real ship. Since the mass production, the 16PA6V-280STC diesel engine has indeed repeatedly experienced the problem of high exhaust temperature in the bench test and the high exhaust temperature of the real ship caused by environmental conditions, re...

Problems solved by technology

The VTC304 supercharger switching point is determined according to the propeller characteristic line, and has not been verified under the external characteristics. During the actual ship operation, the operating area of ​​the diesel engine will exceed the propeller characteristic line. Advanced issues, resulting in multiple revisions of the real ship

Since the mass production, the 16PA6V-280STC diesel engine has indeed repeatedly experienced the problem of high exhaust temperature in the bench test and the high exhaust temperature of the real ship caused by environmental conditions, reflecting the small design margin of the 16PA6V-280STC diesel engine with VTC304 turbocharger
