Summary of the invention
The purpose of this utility model is to produce for the existing air inlet system of diesel engine that strength of vortex is low, deficiency that can not on-line control, and a kind of online adjustable variable air inlet eddy current runner constructional device is provided.
Technical solution adopted in the utility model is:
The utility model device is structure ringwise, is installed in the suction port place of cylinder jacket of diesel engine, specifically comprises blade assembly, driver, wire rope, live axle, driveshaft; Install on the annular circumferential corresponding with the cylinder jacket of diesel engine suction port and have a plurality of fan-shaped gas inlet mouths, in the fan-shaped gas inlet mouth blade assembly is installed, and the head and the tail blade of blade assembly links to each other with wire rope respectively along the neutral position of short transverse, form the enclosed link; Driver is installed on the device between adjacent two blade assemblies, and live axle is installed in the driver, and steel wire disk is fixed with driveshaft on the live axle on live axle, and live axle can clockwise or rotate counterclockwise, and drives the wire rope that is coiled on the live axle;
Described blade assembly is comprised of a plurality of blades, rotating shaft, connecting rod, and blade is streamlined or plate, and rotating shaft is installed on the device and leans on the top and bottom of cylinder of diesel engine side fan-shaped gas inlet mouth, but flexible rotating, for an end of stator blade; Connecting rod connects the other end of adjacent two blades, and its length equates with the rotating shaft spacing of adjacent two blades, thereby makes adjacent two blades form parallelogram shape, so that several pieces blades interlocks freely.
The utility model device working procedure is as follows:
The live axle of driver is connected with fuel-flow control bar or the speed regulator of diesel engine, when diesel engine moves under the low speed, fuel-flow control bar or speed regulator make the live axle deflection on the driver, the pulling wire rope makes all blade synchronization of blade assembly, rotates along the rotating shaft beat in the same way, form the variable air inlet runner that cuts angle, regulate air along the direction air inlet closer to tangent line, thereby improved intake vortex strength, reached can make under the low speed air-fuel mixture more evenly, the more fully purpose of burning.
The beneficial effects of the utility model:
In general, when diesel engine moves under the low speed since intake swirl a little less than, make air-fuel mixture inhomogeneous, the burning insufficient.The utility model can be with the variation of diesel engine speed, the on-line control intake vortex strength especially under the low speed, can obviously increase intake vortex strength, thereby solved the problem of fuel consumption and emission under the diesel engine low speed, had significant economy, society and environmental benefit.
