Abstract

The utility model relates to a turbo charging device with variable outlet area of an exhaust pipe, belonging to the internal-combustion engine technical field, comprising a turbo, an exhaust branch pipe, an exhaust pipe, a baffle, a baffle axle, a baffle rotary handle, wherein the round baffle is arranged in the pipeline at the outlet of the exhaust pipe and concentrically mounted together with the exhaust pipe; the baffle axle and the baffle are fixed together and one end is fixedly connected with the baffle rotary handle and another end passes through the pipe wall above the exhaust pipe and then through the baffle axle hole and then vertically passes through the groove on the pipe wall of the exhaust pipe to smoothly closely contact with the pipe wall of the exhaust pipe. The rotary baffle not only obtains different outlet areas at different operation conditions to satisfy the requirements of economical efficiency and the power. When in the slow running, the outlet area of the exhaust pipe changes smaller; when in fast running, the outlet area of the exhaust pipe changes larger. The design is reasonable to satisfy the variable operation-condition operation requirement of the engine and the device is free from the number of the cylinder and suitable for the turbo single-inlet and provided with the turbo at the side.

Description

The turbo charging installation of exhaust outlet variable area

Technical field

The present invention relates to a kind of internal combustion engine turbocharging device, the turbo charging installation of the exhaust outlet variable area of import of particularly a kind of turbine list and turbine side belongs to technical field of internal combustion engines.

Background technique

Along with the development of society and the raising of environmental requirement, now the engine booster technology is used more and more widely, in powerful motor major part all adopt turbocharging technology, to improve power and to reduce fuel consumption rate.Two kinds of basic pressurization systems of turbosupercharged engine are constant pressure charging system and impulse pressure charging system.Constant pressure charging system, exhaust pipe volume is big, and the pipe internal pressure keeps constant substantially, and the scavenging interference is little, pumping loss is few, and the high-speed working condition performance is good; Impulse pressure charging system, exhaust pipe volume is little, can avoid scavenging to disturb, and can utilize the exhaust pulses energy preferably again, and low speed operating mode and acceleration loading performance are good.Ideal situation is that motor exhaust pipe volume when low speed and the operation of acceleration loading condition can diminish, and realizes the pulse pressure-charging mode, can make full use of pulse energy; Exhaust pipe volume can become greatly when the high engine speeds operating mode is moved, and realizes the constant pressure supercharging mode, and pumping loss is reduced.This shows, if a motor is if be equipped with constant pressure supercharging mode and pulse pressure-charging mode simultaneously, use constant pressure charging system during high-speed working condition, use impulse pressure charging system when low speed and instantaneous conditions, this is comparatively desirable, but the exhaust pipe volume of existing engine booster system substantially all can not be regulated.

The model utility content

In order to overcome the deficiency of prior art, the utility model provides a kind of turbo charging installation of exhaust outlet variable area.The discharge area of outlet pipe changes with the variation of the operating conditions of motor, the exhaust outlet area diminishes during the low speed operating mode, the exhaust outlet area becomes big during high-speed working condition, so that each operating conditions of motor can both obtain more excellent performance, and satisfy the requirement of Economy and power character aspect simultaneously.

The technological scheme that the utility model adopted is for achieving the above object: this device comprises turbine, exhaust branch pipe, outlet pipe, baffle plate, damper shaft, baffle plate rotating handles, turbine is single import turbine, the import of exhaust branch pipe is connected with the cylinder head air outlet flue, the outlet of exhaust branch pipe is connected with outlet pipe, outlet pipe is a pipe, its outlet is connected with the import of turbine, baffle plate is a plectane, place in the pipeline in outlet port of outlet pipe, its diameter is less than the outlet pipe internal diameter, and baffle plate is installed with outlet pipe is concentric; Damper shaft and baffle plate are solidified as a whole, one end and the baffle plate rotating handles of damper shaft are solidified as a whole, after the tube wall break-through of the other end of damper shaft directly over the outlet pipe, pass the axis hole of baffle plate, vertically pierce into again in the tube wall groove under the outlet pipe and with smooth tight contact of tube wall of outlet pipe.In the utility model, the tubular type outlet pipe can guarantee the mobile performance of exhaust preferably.Realize the rotation of baffle plate by the rotation of baffle plate rotating handles, thereby regulate the discharge area of outlet pipe.When motor when the low speed operating mode is moved, butterfly makes its windward side become big, the discharge area of outlet pipe has just diminished like this.When the discharge area of outlet pipe diminished, pumping loss increased, and the available energy before the turbine also increases simultaneously, and the inlet stream quantitative change is big, and in-cylinder combustion improves, and oil consumption reduces.When motor when high-speed working condition moves, butterfly diminishes its windward side, the discharge area of outlet pipe just becomes big like this.When the discharge area of outlet pipe became big, pumping loss reduced, and oil consumption reduces.

The beneficial effects of the utility model: this device is not limited by cylinder number, satisfy the requirement of motor variable parameter operation, be applicable to the turbo charging installation of import of turbine list and turbine side, motor can make burning improve in whole load operation scope, oil consumption reduces, and obtains more excellent performance.
