Abstract

The invention relates to a turbine pressurize diesel engine variable-discharge-tube-volume modular pulse converting pressurize device, formed by a modular pulse converter, an auxiliary discharge tube, a three-way tube and a two-way control valve. The modular pulse converter is formed by an injector and a cylinder discharge tube, wherein, the injector is mounted at one side of discharge channel of the cylinder, the discharge tube of ascending cylinder forms the ascending discharge tube, and the discharge tube of descending cylinder forms the main discharge tube, the descending end of ascending discharge tube is connected with the ascending end of three-way tube; two descending ends of three-way tube are respectively connected to the main discharge tube and the ascending end of the auxiliary discharge tube; the cross of three-way tube is mounted with a two-way control valve; the descending ends of main and auxiliary discharge tube are respectively connected with two ascending ends of pulse converter whose descending end is connected with the inlet of turbine; the ascending end of pulse converter has two reducing tubes while the descending end is mixing tube with equal section. The invention has adjustable volume of discharge tube, to meet the work adjustment of diesel engine, while the application is not limited by the cylinder number.

Description

[0001] This application is a divisional application of the original patent application for the invention, the original application date: August 4, 2004, the application number: 200410050996.3, the name of the invention: a variable modular pulse conversion supercharging device for a turbocharged diesel engine. technical field [0002] The invention belongs to a variable exhaust pipe volume module type pulse conversion supercharging device of a turbocharged diesel engine. Background technique [0003] Diesel engine is the most widely used type of power machinery. Most of the medium and high-power diesel engines adopt turbocharging technology to increase power and reduce fuel consumption. protrude. The two basic supercharging systems of turbocharged diesel engines are constant pressure supercharging system and pulse supercharging system. The structural feature of the constant pressure booster system is that the volume of the exhaust pipe is large, the exhaust pipe plays a role...
