Mechanical disaligned connecting pipe communication system

Abstract

A mechanical disaligned connecting pipe communication system in the technical field of mechanical design comprises intake pipes, an engine, exhaust pipes, an air compressor, a turbine, connecting pipes, a volume chamber, a moving body and a spring, the moving body is mounted in the volume chamber and is in tight contact with the inner wall of the volume chamber, two penetrating pipes run through the upper and lower walls of the moving body, and both ends of the spring are respectively connected with the left wall of the moving body and the left wall of the volume chamber. When the engine is in a low-speed working condition, the moving body moves to the right in the volume chamber, the second connecting pipe communicates with the fifth connecting pipe, the intake air is heated by the residual heat of the exhausted air, and therefore the cold starting performance of the engine is good; when the engine is in a high-speed working condition, the moving body moves to the left in the volume chamber, and the second connecting pipe is partitioned from the fifth connecting pipe. The design of the mechanical disaligned connecting pipe communication system is reasonable, the structure is simple, and the mechanical disaligned connecting pipe communication system is applicable to an engine intake air heating system with a turbocharger.

Description

technical field [0001] The invention relates to an intake and exhaust system in the technical field of mechanical design, in particular to a mechanical connecting pipe dislocation communication system with a turbocharger. Background technique [0002] Harmful emissions from engines are a major source of air pollution. With the increasing importance of environmental protection, the goal of reducing harmful emissions from engines has become an important direction for engine development in the world today. With the world's consumption of petroleum products increasing year by year, the international oil price remains high, and the economy of the engine is becoming more and more prominent. Therefore, it is the primary task of engine designers to carry out research on the control methods of engine harmful emissions. By heating the intake system of the engine, it can not only improve the cold start performance of the engine under harsh conditions, but also reduce the exhaust pollu...
