Description
Technical field
The invention belongs to the vehicular engine technical field.
Background technique
In the engine cylinder direct injection technology most critical be to control well mixture strength spatial distributions with and over time, rely on and adopt air-flow control technique in high-precision high pressure fuel injector, the cylinder, switch combustion mode according to operation range, can reach high fuel economy and high-performance, reduce pollution environment.
What traditional in-cylinder direct fuel-injection engine adopted is the remote arrangement of oil sprayer away from spark plug, oil sprayer is arranged in the air inlet reveal, the opening of corresponding piston crater points to the air inlet side, spark plug is arranged in the middle of the cylinder head, inhaled air is forced to flow downward along cylinder wall by the vertical intake duct with special shape in intake stroke, stream is rolled in formation, lights near at last the fuel oil of the fuel oil that sprays and evaporation being delivered to spark plug.Above-mentioned this wall and air-flow guidance mode make mist of oil and piston head and cylinder wall bump easily, and the temperature of casing wall is lower, thereby causes fuel oil catching fire not as good as evaporation fully, and " wet wall " problem takes place, piston crown is easy to generate carbon distribution, thereby causes deterioration of emission." wet wall " also can make oil dilution, causes main movement parts poor lubrication, serious wear, the working life of reducing correlated parts.
Summary of the invention
The objective of the invention is to propose a kind of can avoiding " wet wall ", motor with good fuel economy and feature of environmental protection.
Motor of the present invention comprises piston, cylinder, oil sprayer and spark plug, particularly be provided with an oil sprayer in each cylinder of motor, described oil sprayer is arranged on the central authorities of cylinder head, described spark plug is near near the also oil nozzle of oblique oil sprayer of the oil nozzle of oil sprayer, and the lateral electrode of described spark plug deviates from the oil nozzle direction of oil sprayer and is positioned at the oily Shu Bianyuan of oil nozzle ejection.
Oil sprayer is arranged in the central authorities of cylinder head, and the oil bundle meeting nature of oil sprayer ejection forms the mixed gas of layering distinctness.Because no matter be homogeneous combustion or stratified mixture combustion, the formation of mixed gas is not very big with intake process, the related of piston face design, so mid-oil sprayer motor of the present invention has saved the air door conversion equipment that traditional side oil sprayer motor need be provided with in intake manifold, make things convenient for the conversion of aflame modes of inflation, simplified the design of intake manifold structure and electronic control.
Tilting oil sprayer utilizes air-flow and wall to make a large amount of rich mixtures concentrate on the spark plug annex, make flame when weak mixture relay towards periphery, cross rare extinguishing because of mixed gas easily, therefore tilting oil sprayer arrangement all has strict requirement to oil sprayer in angle of inclination that cylinder cap is placed and inclined jetting angle etc., must consider the piston face shape simultaneously, air-flow power in the cylinder, injection timing, injection pressures etc. are all multifactor, if being set, the improper mixed gas that causes possibly adheres to wall, fuel gasification deficiency and mixed gas are divided into situations such as not good, thereby influence the process of whole burning.And the present invention is placed on cylinder head central authorities with oil sprayer, spark plug is near near the oil nozzle of oil sprayer, utilize the penetration of spontaneous charge stratification of oil sprayer and oil bundle, guaranteed that mixed gas propagates uniformly, after in whole firing chamber, being full of weak mixture, around spark plug, still have to form the rich mixture of lighting, guaranteed the stability that mixed gas is lighted.Burning occurs over just the peripheral region of spark plug in this stratified charge pattern, so the temperature variation of cylinder wall is little, so thermal losses is less and the thermal efficiency has also improved, avoided the problem of " wet wall " effect and piston carbon distribution, heat in the air inlet is absorbed, thereby obtains cooling, has so just reduced the possibility of engine knock and has improved compressibility, fuel oil is burnt fully, reduced oil consumption and toxic emission.
The oil nozzle of the oblique oil sprayer of described spark plug can guarantee the oil nozzle close together of spark plug and oil sprayer like this, also can not influence the rigidity of cylinder head because the mounting point of spark plug and oil sprayer not cross near.
The lateral electrode of described spark plug deviates from the oil nozzle direction of oil sprayer, promptly is positioned at oily Shu Bianyuan, can avoid mist of oil attached to above the lateral electrode, has prolonged the life-span of spark plug greatly, has saved user cost.
Described oil sprayer can guarantee mist of oil even stratification under jet power and action of gravity, sufficient combustion perpendicular to cylinder head.
Described spark plug utilizes screw thread and cylinder head to fix, the screw place of plug surfaces and cylinder head is provided with the installing and locating mark, by the initial position of screw thread on the spark plug of location and the initial position that spark plug is installed screw thread, the position that can guarantee spark plug its lateral electrode when tightening deviates from the oil nozzle direction just, guarantees the setting angle and the soundness of spark plug.
The external sealed packing ring of described spark plug adopts copper faced washer, stable performance, long service life.
The top of described oil sprayer is pressed abd fixed on the cylinder head by high pressure oil rail, and the oil nozzle of oil sprayer inwardly protrudes in the firing chamber, and high pressure oil rail has not only played the effect of fixing fuel injector, can also kill two birds with one stone to the oil sprayer fuel feeding.
Engine structure of the present invention is simple, has solved " wet wall " problem of conventional engines, has the good fuel economy and the feature of environmental protection, meets the development trend of modern motor.

Embodiment 1:
As shown in Figure 1, the motor of present embodiment comprises piston 1, cylinder, oil sprayer 3 and spark plug 4, particularly be provided with an oil sprayer 3 in each cylinder of motor, described oil sprayer 3 is vertically set on the central authorities of cylinder head 2, near the oil nozzle 31 of described spark plug 4 close also oblique oil sprayers, the lateral electrode 41 of spark plug 4 deviates from oil nozzle 31 directions of oil sprayer 3 and is positioned at the oily Shu Bianyuan of oil nozzle 31 ejections.
For guaranteeing the setting angle and the soundness of spark plug 4, spark plug 4 utilizes screw thread and cylinder head 2 to fix, and the screw place of spark plug 4 surfaces and cylinder head 2 is provided with the installing and locating mark.The external sealed packing ring of spark plug 4 adopts the copper faced washer, and the top of oil sprayer 3 is pressed abd fixed on the cylinder head 2 by high pressure oil rail, and the oil nozzle of oil sprayer 3 inwardly protrudes in the firing chamber.
