The energy-saving piston of described 6160 diesel engines is characterized in that piston crown is provided with four road piston ring grooves.
The energy-saving piston of described 6160 diesel engines, the breach that is characterized in skirt section, pin-and-hole seat lower end is the circular arc cutaway that makes progress from the bottom surface.
The energy-saving piston of described 6160 diesel engines, the circular arc cutaway that is characterized in skirt section, pin-and-hole seat lower end is made up of three sections circular arcs, central segment is to be the circular arc of R with the radius, two ends are respectively to be the circular arc of R1 and R2 with the radius, they respectively with the tangent bottom surface that carries out the transition to of central segment circular arc, to keep the due intensity of piston and to avoid a direct circular arc to be connected the stress undue concentration that causes the joint with guide surface.
The energy-saving piston of described 6160 diesel engines, annular groove one, two, the three road width that are characterized in piston crown assembling piston ring are that 3.5mm is used to install flat ring, the 4th road is an oil ring groove, be used to install the support spring oil ring, width 6mm, reduce 2mm than original structure, such effect more can embody the effect of cloth oil control oil, and has reduced the area of contact of friction.
The energy-saving piston of described 6160 diesel engines is characterized in that piston head thickness is 20 ± 1mm, has both kept the reliability of mechanical strength and work, avoids the interference with parts that is associated such as coupling rod partss, and has reduced piston only weight again effectively.
The energy-saving piston of described 6160 diesel engines is characterized in that the breach in skirt section, pin-and-hole seat lower end forms at above position, bottom surface, piston skirt borehole, and institute's borehole shape can be multiple shape, the same purpose that realizes alleviating piston only weight.
In order to keep the guidance quality of piston, be provided with the guide surface of certain width in lower end, pin-and-hole Vertical direction skirt section, effectively to alleviate piston only weight.
It is 160mm that piston of the present utility model is used in particular for the working cylinder diameter, and number of cylinders is 6 cylinders, and discharge capacity is 6160 diesel engines of 27L.
The beneficial effect that the utility model is obtained is: piston weight is reduced to 4280-4380 by 5180-5230g, reduced 800-950g, thereby make the to-and-fro motion inertial force of diesel engine reduce by 25%, the impact of the inertial force when greatly reducing host work and the loss of useful horsepower; Adopting Fourth Ring groove structure and skirt section is the circular arc cutaway structure, and the kinetic friction area of contact has reduced 20%, makes the frictional work loss of diesel engine reduce by 20%, simultaneously the corresponding leakage path that reduced; Because the optimal design of skirt section shape face and cylinder prepareding gap, reduced the gas leakage amount of diesel engine effectively and improved useful horsepower; The combination property of piston shows as: the useful horsepower of diesel engine has improved 12KW, has promoted 5%; Fuel consume has reduced by 4%; Lubricating oil consumption has reduced by 20%; Piston life has improved 2000h; Reduced the discharging and the operational noise of pollutant simultaneously, reached saving petroleum-based energy, protection atmosphere environment, improved the product purpose in working life, this piston is convenient to processing, has reduced cost.
