Description
Technical field
The invention belongs to Diesel Engine Technique Field, it is related to a kind of burning chamber of diesel engine and improves burning chamber of diesel engine carbon distribution
Method.
Background technique
Diesel engine belongs to wet combustion, during operation, can generate hard carbon in portion in the combustion chamber.With piston
It moves back and forth, carbon is deposited in cylinder jacket top, generates friction with cylinder liner internal wall, and it is inclined to may cause cylinder jacket generation part
Mill aggravates the abrasive wear of cylinder sleeve and piston, shortens the service life of the components such as cylinder jacket, piston ring, piston.
Summary of the invention
In order to solve the problems, such as that burning chamber of diesel engine carbon is accumulated, the invention proposes a kind of burning chamber of diesel engine and change
The method of kind burning chamber of diesel engine carbon distribution avoids carbon distribution hardening, accumulation in burning chamber of diesel engine, extends the use of relative motion pair
Service life improves the reliability of diesel engine.
In order to solve the above-mentioned technical problem, technical scheme is as follows:
A kind of burning chamber of diesel engine, piston and cylinder jacket are equipped with step structure near top dead center locations, for placing
Scrape carbocyclic ring；It scrapes carbocyclic ring clearance fit and is mounted on cylinder jacket at the step structure of near top dead center position.
Further, scraping carbocyclic ring is thin wall cylinder-shaped part.
Further, it is dismountable for scraping carbocyclic ring.
Further, carbocyclic ring use material identical with cylinder jacket is scraped.
A method of improving burning chamber of diesel engine carbon distribution, is included in piston and cylinder jacket in top dead center position and step is set
Structure scrapes carbocyclic ring in step structure clearance fit installation.
Further, scraping carbocyclic ring is thin wall cylinder-shaped part.
Advantageous effects of the invention:
1, the cutting edge that the present invention can make the carbon distribution of piston crown constantly be scraped carbocyclic ring in the reciprocating motion of piston strikes off, and hinders
The accumulation of piston crown carbon is stopped；The carbon distribution being removed is blown out with exhaust, the micro carbon distribution base of residue of piston crown
Cylinder liner surface will not be touched on this, also just not adsorbing lubricating oil brings combustion chambers burn into.Avoiding problems a large amount of lubricating oil
" pump " burn up this " pump oil phenomenon " into combustion chamber, it is ensured that cylinder liner-piston group remains good lubricating status, makes
The abrasion and lubricating oil oil consumption of cylinder sleeve and piston ring substantially reduce.
2, with scrape the matched cylinder sleeve of carbocyclic ring and will not change the size dimension of diesel engine or cylinder head when redesigning,
Versatility is good.
3, scraping carbocyclic ring is thin wall cylinder-shaped part, uses material identical with cylinder jacket, it can be ensured that scrape carbocyclic ring and cylinder
Consistency when set thermal expansion.
4, the present invention is at low cost, quick, profitable, easy to spread.
Detailed description of the invention
Fig. 1 is to cooperate schematic diagram without the piston and cylinder sleeve for scraping carbocyclic ring；
Fig. 2 is that band scrapes the piston of carbocyclic ring and cylinder sleeve cooperates schematic diagram.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of burning chamber of diesel engine provided by the invention, piston 1 and cylinder jacket 2 are equipped with step near top dead center locations
Structure scrapes carbocyclic ring 4 for placing；It scrapes carbocyclic ring clearance fit and is mounted on cylinder jacket at the step structure of near top dead center position.
The present invention, can be by early stage carbon distribution by the way that in burning chamber of diesel engine cylinder jacket, close to top dead centre position, carbocyclic ring is scraped in installation
It is removed in time, avoids carbon distribution hardening, accumulation, extend the service life of relative motion pair, improve the reliability of diesel engine.
It scrapes carbocyclic ring design installation to be gap-matched, cooperates matched cylinder sleeve and piston, operated in diesel engine
Cheng Zhong achievees the purpose that carbon remover.Fig. 1 is to cooperate schematic diagram without the piston and cylinder sleeve for scraping carbocyclic ring, and Fig. 2 is that band scrapes carbocyclic ring
Piston and cylinder sleeve cooperate schematic diagram.
With the design structure for scraping carbocyclic ring, piston and cylinder sleeve have step structure design in top dead center position, for putting
It sets and scrapes carbocyclic ring.
Scraping carbocyclic ring is the thin wall cylinder-shaped components for being assemblied in cylinder jacket top (piston top dead centre position), by
Gap cooperation is placed in cylinder jacket.On the one hand, the design for being less than inner diameter of cylinder sleeve due to scraping carbocyclic ring internal diameter, in reciprocating motion of the pistons
In the process, the carbon of generation of burning constantly is scraped carbocyclic ring and the cutting edge of piston ridge strikes off, and prevents piston crown carbon
Accumulation；On the other hand, scrape that carbocyclic ring is quick detachable, replaceable, at low cost, be able to extend the components such as cylinder sleeve, piston uses the longevity
Life.
The present invention has the advantages that
The cutting edge that the present invention can make the carbon distribution of piston crown constantly be scraped carbocyclic ring in the reciprocating motion of piston strikes off, and prevents
The accumulation of piston crown carbon；The carbon distribution being removed is blown out with exhaust, and the micro carbon distribution of residue of piston crown is basic
On will not touch cylinder liner surface, yet just do not adsorb lubricating oil and bring combustion chambers burn into.Avoiding problems a large amount of lubricating oil
" pump " burn up this " pump oil phenomenon " into combustion chamber, it is ensured that cylinder liner-piston group remains good lubricating status, makes
The abrasion and lubricating oil oil consumption of cylinder sleeve and piston ring substantially reduce.Meanwhile with scrape the matched cylinder sleeve of carbocyclic ring redesign when
The size dimension of diesel engine or cylinder head will not be changed, versatility is good.Scrape carbocyclic ring be thin wall cylinder-shaped part, using with gas
The identical material of cylinder sleeve, it can be ensured that scrape consistency when carbocyclic ring and cylinder jacket thermal expansion.Its is at low cost, quick, profitable,
It is easy to spread.
Embodiments of the present invention are elaborated above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of one of ordinary skill in the art can also be before not departing from spirit of the invention
Put that various changes can be made.
