Description
Technical field
The present invention relates to the explosive motor field, relate in particular to a kind of no carbon distribution motor.
Background technique
Along with the development of society, automobile production and sales volume constantly increase, and motor car engine carbon distribution problem constantly manifests, and carbon distribution also is the difficult problem on the world car development history.Carbon distribution is meant behind the gas blowby mixing partial combustion of explosive motor fuel and lubricant oil and the sediments that produces.It is reported that Japan and Korea S should remove one time carbon distribution about the general 30000KM of vehicle, most for hanging down the high pili torti motivation of commentaries on classics because Japan and Korea S are open form, emphatically than the slow speed driving, carbon distribution is relatively little to engine's motive power and oil consumption influence.On the contrary, the America and Europe will remove one time carbon distribution about the general 20000KM of vehicle, the America and Europe is a high rotating speed engine during the vehicle majority is, reaching certain rotating speed becomes real power just to export, majority is high rotating speed driving in being, but in high rotating speed must pass through the slow-speed of revolution earlier, carbon distribution embodies more obvious when the slow-speed of revolution is quickened to the influence of engine.During engine operation, because the burning and a large amount of heat of the friction-produced between moving parts of fuel, make the operating temperature of motor very high, the component (piston, piston ring, cylinder wall, intake valve, cylinder head, spark plug, head gasket etc.) that particularly constitute the firing chamber directly contact with high-temperature gas, its temperature is higher, reach about 2000 ℃, if not suitably and timely cooling, motor is with regard to cisco unity malfunction.And along with motor adopts compact more design and has bigger specific power, the used heat density that motor produces also obviously increases thereupon.
The too high meeting of engine temperature makes lubricant oil become rare because of oily temperature rise, the oil film of each lubricant housings of motor is difficult for forming or is destroyed, semi-dry friction or even dry friction will appear in each matching pair surface, cause easily that lubricant oil burns, carbon distribution and lose lubricating function, thereby the acceleration component wear, the working life of reducing motor; Engine overheat, metal parts is under long high temperature action, and its intensity, elasticity, wear resistance all can descend, and produce thermal stress, distortion, crackle and expansion finally occur, and change the matching gap between the part, influence the engine operation performance; Engine overheat makes the air expanded by heating that enters cylinder, and air density reduces, and causes volumetric efficiency to descend; Diesel engine produces pre-ignition, and aeration quantity reduces, and frictional loss increases; Because the air inlet amount reduces relatively, fuel oil and Air mixing are out of proportion, make the combustion process of diesel engine undesired, and pre-ignition or deflagration phenomenon can take place, thereby oil consumption increases, and power descends, the outlet pipe over-emitting black exhaust, and the reliability of work and durability worsen; When serious, can make moving parts lose normal clearance because of expanded by heating, frictional force increases, and causes piston scraping or pernicious fault such as stuck.
Summary of the invention
The technical problem to be solved in the present invention provides the no carbon distribution motor of a kind of simple in structure, good cooling results, good operation stability.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of no carbon distribution motor, comprise cylinder block, this cylinder block is provided with water-cooled cavity and at least two sleeve ports, each sleeve port all mates is equipped with cylinder, with the cylinder sleeve hole wall of cooling water contact on or in corresponding cylinder, offer the groove or the open-work of some on the cylinder sleeve hole wall of piston stroke section.
The longitudinal section of described groove or open-work is a variable cross section.
A kind of no carbon distribution motor comprises single cylinder, and on this cylinder outer wall that contacts with cooling water or offer the groove of some on the cylinder outer wall of piston stroke section, and the longitudinal section of groove is a variable cross section.
Described groove is round table-like, or is the terrace with edge shape, or is coniform, or is pyramid-shaped.
The cross section of described groove is n angle star, and n is less than 10 natural number greater than 3.
Spacing between the described groove is 2～25mm.
The cylinder wall thickness of described bottom portion of groove position is 2～30mm.
The upper edge diameter of described groove is 1.5～10mm.
Described cylinder outer wall and groove surfaces lining hard formation or carry out nitriding treatment, improve its surface hardness and degree of finish, as adopt chromium plating, nitriding, spray pottery, be coated with epoxy resin or be coated with technologies such as nylon, coat different coating layers at cylinder outer surface and groove surfaces, can effectively resist the cavitation pitting of cylinder block outer wall.Also can on cylinder or sleeve port outer wall, be coated with anti-cavitation pitting material and absorbing material, as far as possible reduce its roughness, increase technical measures such as aiding support.
The present invention has positive beneficial technical effects:
1. increase the heat exchange area of cylinder outer wall and cooling water, be beneficial to and strengthen reaching in the cylinder distributing of cylinder wall heat, to reduce the high temperature of cylinder wall fast and effectively, the lubricity that keeps cylinder, make cylinder inner wall moistening and as bright as a sixpence, and the flexibility and the working life of having improved parts such as cylinder, piston, connecting rod, bent axle, can make engine life prolong one times; And can prevent high temperature sintering carbon distribution (motor does not almost need de-carbon all the life), and make cylinder be in suitable heat load state, the abundant burning of favourable fuel oil keeps powerful power output, saves fuel oil 5～13%.
2. adopt the present invention can not reduce the intensity of cylinder or cylinder block, owing to cylinder wall became uneven one, can reduce or avoid the generation of resonance phenomenon simultaneously, to strengthen the motor traveling comfort.
3. the present invention has the heat load of simple in structure, good cooling results, reduction piston, cylinder, makes the more reliable advantage of its work, is widely used in various types of water-cooled IC engines.
