Description
Technical field
The utility model is related to a kind of diesel engine without cylinder sleeve cylinder body, belongs to Diesel Engine Technique Field.
Background technology
At this stage, the backwardness of China's diesel technology, poor product quality and vehicle are taken effective measures using middle maintenance,
Low performance, maximum discharge diesel vehicle is caused to be had undesirable effect in use to urban environment and air quality.With diesel engine to
High power, high reliability, low oil consumption development, for China's engine fuel consumption quantity is big, burning is insufficient, noise is big, urgently
Treat the reality that technology upgrading is regenerated, and market for the requirement that diesel engine is more compact, power per liter is big, noise is small, vibration is small, ginseng
See Fig. 1, existing six cylinders Diesel engine obviously can not meet the demand of future market, need to design and develop for this brand-new
It is efficient, energy-conservation, low-emission high-power engine.
Utility model content
The utility model is in view of the deficienciess of the prior art, provide a kind of diesel engine without cylinder sleeve cylinder body, using without cylinder sleeve
Without seam at design, cylinder-bore, compared with having cylinder sleeve diesel engine, due to eliminating cylinder sleeve, the wall thickness of cylinder holes is added, can be subtracted
The deformation of small cylinder holes, the sealing of piston ring, reduces air leak amount when further improving diesel engine work.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of diesel engine is without cylinder sleeve cylinder body, including machine
Housing, described casing body is provided with cylinder-bore, and cylinder-bore is connected with apopore, cylinder-bore and is connected with piston component, described
Piston component includes piston ring, and the piston ring of the piston component is directly contacted with cylinder-bore inwall；Set on the downside of the casing body
There is cooling liquid inlet, the apopore bore described in coolant flow direction gradually increases.
A kind of diesel engine as described above is without cylinder sleeve cylinder body, and described cylinder-bore inwall is carved with flat-top cob-webbing.Cylinder-bore
Inner surface carries out laser and beats quarter flat-top cob-webbing, possesses oil storage effect, it is possible to increase cylinder holes lubricity, wearability.
A kind of diesel engine as described above is provided with fixed seat, machine housing top surface without cylinder sleeve cylinder body, described casing body side
It is provided with bolt hole, alignment pin.Fixed seat, bolt hole, alignment pin are mainly used in stationary housing.
A kind of diesel engine as described above is without cylinder sleeve cylinder body, and described casing body side is provided with blast pipe.Blast pipe is used
In the gas of discharge cylinder block bad student.
A kind of diesel engine as described above is without cylinder sleeve cylinder body, and described apopore is arranged on described cylinder-bore side, goes out
Water hole bore increases and increased with the distance away from cylinder-bore.Using such a design can make coolant according to flow velocity and pressure not
Together, uniformly discharged from each apopore.
The beneficial effects of the utility model are：Cylinder body is used without cylinder sleeve design, and piston ring, piston directly act on cylinder
Body, due to eliminating cylinder sleeve, adds the wall thickness of cylinder holes, can reduce the deformation of cylinder holes, when further improving diesel engine work
The sealing of piston ring, reduces air leak amount, while enabling the heat that diesel engine is produced when working directly by piston ring and cylinder
The contact of body is delivered in the coolant of diesel engine, further improves the heat-sinking capability of diesel engine, with efficient, energy-conservation excellent
Point, cylinder body service life is long, perfect heat-dissipating.
Brief description of the drawings
Fig. 1 is conventional diesel engine housing structure schematic diagram；
Fig. 2 is the utility model diesel engine without cylinder sleeve housing structure schematic diagram.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in Fig. 2 the present embodiment provides a kind of diesel engine without cylinder sleeve cylinder body, including casing body 1, described casing body 1
Cylinder-bore 2 is provided with, cylinder-bore 2, which is communicated with apopore 3, cylinder-bore 2, is connected with piston component 4, and the piston component 4 includes
Piston ring, the piston ring of the piston component 4 is directly contacted with the inwall of cylinder-bore 2；The downside of casing body 1 is entered provided with coolant
Mouth 5, the bore of apopore 3 described in coolant flow direction gradually increases.
Diesel engine is without in cylinder sleeve cylinder body one embodiment, and the described inwall of cylinder-bore 2 is carved with flat-top cob-webbing.Cylinder-bore 2
Inner surface carries out laser and beats quarter flat-top cob-webbing, and flat-top cob-webbing possesses oil storage effect, it is possible to increase cylinder holes lubricity, wearability.
Diesel engine is without in cylinder sleeve cylinder body one embodiment, and the described side of casing body 1 is provided with fixed seat 6, the top surface of casing body 1
It is provided with bolt hole 7, alignment pin 8.Fixed seat 6, bolt hole 7, alignment pin 8 are mainly used in stationary housing.
Diesel engine is without in cylinder sleeve cylinder body one embodiment, and the described side of casing body 1 is provided with blast pipe.Blast pipe is used for
Discharge the gas of cylinder block bad student.
Diesel engine is without in cylinder sleeve cylinder body one embodiment, and described apopore 3 is arranged on the described side of cylinder-bore 2, goes out
