Abstract
The utility model relates to an energy saving type piston of a vortex diesel engine, which is characterized in that the top part of the piston is provided with two double shallow vortex pit type circular vortex chambers, the middle parts of which are provided with flow guiding grooves. The bottom parts of the two vortex chambers are plane surfaces. Both sides of each flow guiding groove are intercrossed with the two vortex chambers. In the process of the compression of the utility model, mixed gases flow on the vortex chambers of the top part of the piston and inclined planes of the flow guiding grooves to form three-dimensional compression vortexes and flat compression vortexes. In a stroke of explosion (operation), overrich mixed gases which are sprayed out of the vortex chambers are sufficiently mixed with the compression vortexes in a gas way at the top part of the piston, and therefore, the vortex intensity is reinforced, the complete burning process is improved, powerful burning explosive power is formed, the utilization rate of burnt oil and the efficiency of an engine are improved, and the oil consumption and the environment pollution are reduced.
Description
Technical field:
The utility model relates to a kind of diesel motor piston, the energy-saving piston of especially a kind of vortex type diesel engine.
Background technique:
Piston is the critical piece that in the internal-combustion engine heat energy is changed into mechanical energy, and its structure determines the efficient of transformation of energy to a great extent, directly has influence on the power and the economic performance of motor.Use diesel engine in China very big quantity to be arranged as the farm tractor of power, as Dongfanghong 802/70,75/60, type tractors such as car pusher 55/55c, it is the major impetus type of the present agricultural production of China, owing to the reason on its structural design, in production run, show as dynamic property less than the nominal power value, efficient is low, cause energy waste and discharge nonconforming and befouling environment, the direct result that causes to the peasant then is that agriculture production cost increases, productivity effect descends, and has had a strong impact on the development of agricultural production.
Technology contents:
The purpose of this utility model is to provide a kind of energy-saving piston of vortex type diesel engine that can improve engine efficiency largely and reduce environmental pollution.
The piston head that is characterised in that of the present utility model is provided with the formula circular vortex chamber, two shallow eddy current hole that two centres have guiding gutter, and the bottom of two vortex chambers is the plane, and cut mutually with two vortex chambers the both sides of described guiding gutter.
The length direction of above-mentioned guiding gutter preferably departs from the center of circle of piston, and is, the center of circle one end shallow inclined-plane dark by piston edge one end.
Above-mentioned guiding gutter can be rectangle, and cut mutually with two vortex chambers both sides; Also can be V-shaped, two corners of " V " shape are stopped up mutually with eddy current and are cut.
The top-ring groove of above-mentioned piston is best apart from the piston head edge<8mm.
The utility model in compression process, mixed gas the piston head eddy current stop up and the inclined-plane of guiding gutter on flow, form the compression swirl of existing solid, also have the flat compressed eddy current.When outburst (work done) stroke, carrying out more fully by the Over-rich mixture of vortex chamber ejection at piston head and compression swirl, gas mixes, strengthen strength of vortex, improve the perfect combustion process, form more powerful burning explosive force, improve the utilization ratio of fuel oil and the efficient of motor, reduced oil consumption rate and environmental pollution.
