Abstract
A kind of S-shaped folds its structure of internal combustion engine its structure main of mouth formula annular groove mainly by piston only (11), first S-shaped folds choma groove (12), second S-shaped folds choma groove (13), piston pin bore (14) is constituted, described this S-shaped is folded mouth formula groove piston and be it is characterized in that: at piston only (11) upper processing twice S-shaped lap-ended piston ring annular groove, i.e. first S-shaped folds choma groove (12) and second S-shaped folds choma groove (13), piston pin bore (14) it is machined with by normal piston, the piston ring annular groove fabrication and processing of this piston becomes S-shaped and folded mouth structure to not only increase piston abrasion-proof, sealing, also reduce the harmful gas of engine emission simultaneously, thus reach to extend the purpose that electromotor serviceability improves.
Description
Technical field:
The invention belongs to an important spare part piston of automobile engine, it is specifically related to a kind of S-shaped and folds mouth formula annular groove
Internal combustion engine.
Background technology:
It is known that along with automobile volume of production and marketing constantly rises, auto Parts Industry is risen the most therewith, day must be met increasingly
Acute automobile production industry, is exactly after market subsequently.Manufacture automobile engine all kinds of resource transition consumption useless, environment for human survival day
Benefit is contaminated, and the most day by day becomes the obstacle of modernization, also result in countries in the world and the great attention of expert at different levels.Send out
Motivation, as the core component of the vehicles, is that power consumption total amount is most at present, the power product that discharge amount of exhaust gas is maximum.And start
The utilization of the how many pairs of social energy of effective work efficiency size of machine and the harmful gas of discharge and environmental Kuznets Curves serve to
Close important effect.To this end, countries in the world have put into effect engine emission standard the most in succession, Environmental Protection in China general bureau has also promulgated pressure
Property discharge standard.Therefore pass by traditional piston and seal far from adapt to this high leakproofness of current electromotor, low emission
The requirement of property.For meeting above-mentioned performance and requiring that I spy has invented this S-shaped and folded the internal combustion engine sealing of mouth formula annular groove
Good, reduce its noxious gas emission.
Summary of the invention:
Technical solution of the present invention, can improve the sealing of piston, effectively reduces the noxious emission of internal combustion engine；
A kind of S-shaped folds its structure of internal combustion engine its structure main of mouth formula annular groove mainly by piston only (11), and first
Road S-shaped folds choma groove (12), and second S-shaped folds choma groove (13), and piston pin bore (14) is constituted, and described this S-shaped folds mouth
Formula groove piston is characterized in that: at piston only (11) upper processing twice S-shaped lap-ended piston ring annular groove, i.e. first S-shaped folds mouth
Annular groove (12) and second S-shaped fold choma groove (13), are machined with piston pin bore (14) by normal piston, and this piston fills
After upper lap-ended piston ring, sealing is preferable.
For reaching above-mentioned purpose, the piston ring annular groove fabrication and processing on piston is become S-shaped and folded mouth structure；
In such scheme, this S-shaped folds the internal combustion engine of mouth formula annular groove, is fabricated to piston ring annular groove fabrication and processing
S-shaped and folded mouth structure not only increase piston abrasion-proof, sealing, also reduce the harmful gas of engine emission simultaneously, from
And reach to extend the purpose that electromotor serviceability improves, and then also reach economic benefit and the situation of social benefit multi-win.
Accompanying drawing illustrates:
Fig. 1 is the internal combustion engine structural representation that a kind of S-shaped of the present invention folds mouth formula annular groove
Detailed description of the invention:
S-shaped a kind of to the present invention is folded the internal combustion engine of mouth formula annular groove and is described in further detail below in conjunction with the accompanying drawings, this
Kind of S-shaped folds the internal combustion engine of mouth formula annular groove mainly by piston only (11), and first S-shaped folds choma groove (12), second S-shaped
Folded choma groove (13), piston pin bore (14) is constituted.
Described this S-shaped is folded the internal combustion engine of mouth formula annular groove and be it is characterized in that: it is characterized in that: on piston only (11)
Processing twice S-shaped lap-ended piston ring annular groove, i.e. first S-shaped fold choma groove (12) and second S-shaped folds choma groove (13), by just
Often piston is equally machined with piston pin bore (14), and after this piston loads onto lap-ended piston ring, sealing is preferable.
A kind of S-shaped of the technical program folds the internal combustion engine of mouth formula annular groove, for reaching above-mentioned purpose, by the piston on piston
Ring annular groove fabrication and processing becomes S-shaped and folded mouth structure.
In such scheme, this S-shaped folds the internal combustion engine of mouth formula annular groove, is fabricated to piston ring annular groove fabrication and processing
S-shaped and folded mouth structure not only increase piston abrasion-proof, sealing, also reduce the harmful gas of engine emission simultaneously, from
And reach to extend the purpose that electromotor serviceability improves, and then also reach economic benefit and the situation of social benefit multi-win.
Claims (1)
1. a S-shaped folds its structure of piston of mouth formula annular groove mainly by piston only (11), and first S-shaped folds choma groove (12),
Second S-shaped folds choma groove (13), and piston pin bore (14) is constituted, and described this S-shaped is folded mouth formula groove piston and be it is characterized in that:
Choma groove (12) and second S-shaped is folded at piston only (11) upper processing twice S-shaped lap-ended piston ring annular groove, i.e. first S-shaped
