Abstract
The utility model relates to an energy saving piston of a vortex diesel engine. The top part of the piston is provided with circular air inlet and outlet vortex pits with unequal diameters corresponding to the position of air inlet and outlet valves. The depth of the two vortex pits are unequal, and the bottom part is a plane. The middle of the two vortex pits is provided with a flow guiding groove, both sides of which is cut with the vortex pits. The horizontal central line of the two vortex pits is arranged on the horizontal central line of the top part of the piston. The vertical central line of the flow guiding groove is arranged on the vertical central line of the top part of the piston. The diameter and the depth of the circular air inlet vortex pit with unequal diameters are bigger than the diameter and the depth of the air outlet vortex pit. The volume ratio of the air inlet vortex pit and the air outlet vortex pit is 1.5 to 1.6: 1. In the compression stroke, mixture gas forms a tridimensional vortex in a vortex chamber. The utility model has the advantages that the intensity of the vortex is enhanced, the combustion process is more sufficient, the powerful burning explosive force is generated, the utilization rate of fuel oil and the engine power is increased, the energy source is effectively saved and the environmental pollution is reduced.
Description
Technical field
The utility model relates to a kind of diesel motor piston, especially a kind of vortex type diesel engine energy-saving piston
Background technique
Structure of piston directly has influence on the power and the economic performance of motor in the internal-combustion engine, China is producing at present and the diesel engine majority that uses is vortex type, large in number and widely distributed, owing to the reason in the piston structure design, general reaction power deficiency, oil consumption are higher, the heat energy transformation efficiency is low, causes energy waste, environmental pollution, cost of production increase, productivity effect to descend.
Summary of the invention
The purpose of this utility model is to provide a kind of vortex type diesel engine energy-saving piston that can improve diesel engine heat energy transformation efficiency and reduce environmental pollution.
The piston head that is characterised in that of the present utility model is provided with and corresponding waney round inlet and outlet eddy current hole, inlet and outlet door position, the depth in two eddy current holes is unequal, the bottom is the plane, centre in two eddy current holes is provided with guiding gutter, cut mutually with the eddy current hole guiding gutter both sides, the horizontal center line in two eddy current holes is on the horizontal center line of piston head, and the vertical center line of guiding gutter is on the vertical center line of piston head.
The diameter and the depth ratio exhaust eddy current hole in above-mentioned waney round intake swirl hole are big, and its volume ratio is preferably 1.5-1.6: 1.
The utility model is in compression stroke, and mixed gas can form three-dimensional eddy current in the vortex chamber, strengthened strength of vortex, make combustion process more abundant, produce more powerful burning explosive force, improved fuel utilization ratio and engine power, save the energy effectively, reduced environmental pollution.
