Summary of the invention
The object of the invention 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, a kind of online adjustable variable air inlet eddy current runner constructional device is provided.
The technical solution used in the present invention is:
Apparatus of the present invention are structure ringwise, is arranged on the suction port place of cylinder jacket of diesel engine, specifically comprises blade assembly, driver, wire rope, live axle, driveshaft; Install in the annular circumferential corresponding with cylinder jacket of diesel engine suction port and have multiple fan-shaped gas inlet mouths, in fan-shaped gas inlet mouth, blade assembly is installed, and the head and the tail blade of blade assembly is connected with wire rope respectively along the neutral position of short transverse, form enclosed link; Driver is arranged on the device between adjacent two blade assemblies, and live axle is installed in driver, and steel wire disk, on live axle, is fixed with driveshaft on live axle, and live axle can clockwise or rotate counterclockwise, and drives the wire rope being coiled on live axle;
Described blade assembly is made up of multiple blades, rotating shaft, connecting rod, and blade is streamlined or plate, and rotating shaft is arranged on device by the top and bottom of cylinder of diesel engine side fan-shaped gas inlet mouth, can flexible rotating, for one 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 link freely.
Apparatus of the present invention working procedure is as follows:
The live axle of driver is connected with fuel-flow control bar or the speed regulator of diesel engine, in the time that diesel engine moves under the low speed, fuel-flow control bar or speed regulator make the live axle deflection on driver, pull wire rope to make all blade synchronization of blade assembly, rotate along rotating shaft beat in the same way, form the variable air inlet runner cutting 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 object more fully of burning.
Beneficial effect of the present invention:
In general, when diesel engine moves under the low speed, a little less than intake swirl, make air-fuel mixture inhomogeneous, burn insufficient.The present invention can be with the variation of diesel engine speed, on-line control intake vortex strength, especially under the low speed, can obviously increase intake vortex strength, thereby the problem that has solved fuel consumption and emission under diesel engine low speed, has significant economy, society and environmental benefit.
