Summary of the invention
The objective of the invention is to produce low, the deficiency that can not online adjusting of strength of vortex, a kind of online adjustable variable air inlet eddy current runner constructional device is provided to the existing air inlet system of diesel engine.
The technological scheme that the present invention taked is:
Apparatus of the present invention are 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 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 with the cylinder jacket of diesel engine suction port; 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 to be coiled in the wire rope on the live axle;
Described blade assembly is made up 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, can rotate flexibly, is used for fixing an end of 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.
Apparatus of the present invention working procedure is following:
The live axle of driver is connected with the fuel-flow control bar or the speed regulator of diesel engine; When diesel engine moves under 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, forms the variable air inlet runner that cuts angle, and regulates air along the direction air inlet that more approaches tangent line; Thereby improved intake vortex strength, reached and to make under low speed that oil gas mixes more evenly, the purpose more fully of burning.
Beneficial effect of the present invention:
In general, when diesel engine moves under low speed because a little less than the intake swirl, make oil gas mix inhomogeneous, burning is insufficient.The present invention can be with the variation of diesel engine speed; Online adjusting intake vortex strength under low speed, can obviously increase intake vortex strength especially; Thereby solved the problem of fuel economy and discharging under the diesel engine low speed, had remarkable economical, society and environmental benefit.
