Abstract
A kind of supercharged direct-injection engine cylinder head, includes cylinder head, air intake duct, exhaust manifold.Its spark-plug hole central axis and oil injector hole central axis are coplanar, and spark-plug hole central axis and oil injector hole central axis coplanar flat are located among cylinder head in the middle part of oil sump.At an angle, oil injector hole central axis and vertical direction are at an angle for spark-plug hole central axis and vertical direction in the plane.Each cylinder injector hole, spark-plug hole are located at the top of cylinder cap, and fuel injector is directly to cylinder injection fuel.Coordinate unique chamber structure shape, and highest 350bar fuel-injection pressure, can greatly optimize fuel combustion efficiency, improve burning efficiency, reduce oil consumption, improve emission effect.Spark plug and fuel injector the oil sump central plane among cylinder head, and its center axis uses the arrangement of small angle with vertical direction, can shorten length of the cylinder cap in horizontal and vertical direction, saves arrangement space.
Description
Technical field
The utility model belongs to automobile technical field, and in particular to a kind of supercharged direct-injection engine cylinder head.
Background technology
Engine cylinder cap is the important component of internal combustion engine, by with closing cylinder upper, forming combustion chamber；And do
For the support of numerous annexes.As regulation automobile emission regulation and combustion fuel economy regulation are more and more stricter, and the demand in market, need
Cylinder head performance is optimized, upgraded；Simultaneously with Engine Downsizing trend, it is proposed that reduce cylinder head arrangement space
Requirement.
Utility model content
The purpose of this utility model is intended to overcome deficiency of the prior art to provide, and a kind of high combustion efficiency, oil consumption be low, row
Put and pollute small, the small supercharged direct-injection engine cylinder head of arrangement space.
The utility model adopts the following technical scheme that realization：
A kind of supercharged direct-injection engine cylinder head, the cylinder head include multiple spark-plug holes and with each spark-plug hole phase
The oil injector hole of matching, the central axis of the spark-plug hole are in same plane, and the central axis of the oil injector hole
In the plane.The plane is arranged on cylinder and covers two row's cylinder cap mounting hole middles.
Further, the spark-plug hole and oil injector hole are arranged in the square mounting groove of engine cylinder cap, described
Square mounting groove and the oil sump of cylinder head independently separate, and are sealed by valve mechanism cover.
Further, the spark-plug hole central axis and vertical direction are in 6.5 ° of -8.5 ° of angles, preferably 7.5 °, oil spout
Device hole central axis and vertical direction are in 7 ° of -9 ° of angles, preferably 8 °.
Further, the spark-plug hole central axis and oil injector hole central axis are on cylinder cap and cylinder body fitting surface
Distance is 10mm-12mm, preferably 11mm.
Further, the cylinder head is provided with fuel injector installation bolt hole between spark-plug hole and oil injector hole.
Due to being respectively positioned on square installation among cylinder head using said structure, the utility model oil injector hole and spark-plug hole
In groove, spark-plug hole central axis and oil injector hole central axis are coplanar, spark-plug hole central axis and oil injector hole central shaft
Line coplanar flat is located among cylinder head in the middle part of oil sump, can so shorten length of the cylinder cap in horizontal and vertical direction, saves
Arrangement space.In the plane spark-plug hole central axis and vertical direction at an angle, oil injector hole central axis with it is vertical
Direction at an angle, can greatly optimize fuel combustion efficiency, improve burning efficiency, reduce oil consumption, reaching the discharge of state six will
Ask.
In summary, present apparatus spark plug and fuel injector are in square mounting groove, its center axis is with hanging down among cylinder head
Nogata can shorten length of the cylinder cap in horizontal and vertical direction, save arrangement space to the arrangement using small angle.Respectively
Cylinder injector hole, spark-plug hole are located at the top of cylinder cap, and fuel injector is directly to cylinder injection fuel.Coordinate unique chamber structure shape
It shape, and highest 350bar fuel-injection pressure, can greatly optimize fuel combustion efficiency, improve burning efficiency, reduce oil
Consumption, reaches the emission request of state six.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 be in Fig. 1 A to sectional view.
In accompanying drawing：The square mounting grooves of 1-, 2- spark-plug holes, 3- oil injector holes, 4- fuel injector installation bolts hole, 5- cylinder caps peace
Fill hole.
Embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, a kind of supercharged direct-injection engine cylinder head, the engine cylinder cap include cylinder head, air inlet
Road, exhaust manifold；Square mounting groove 1 is specially designed among cylinder head, oil injector hole 3 and spark are arranged in square mounting groove 1
Consent 2.Square mounting groove 1 independently separates with cylinder head oil sump, is sealed by valve mechanism cover, avoids cylinder head oil sump inner fluid from entering
Enter square mounting groove.In this example, number of cylinders is 4 in cylinder head, the central axis of spark-plug hole 2 and the oil injector hole 3 of each cylinder
Central axis is coplanar, and the central axis of spark-plug hole 2 and the central axis coplanar flat of oil injector hole 3 are located at square peace among cylinder head
Tankage.Fuel injector installation bolt hole 4 is located at the lateral position of oil injector hole, and among both oil injector hole and spark-plug hole
Position.
Further, on spark-plug hole central axis and oil injector hole central axis coplanar flat, spark-plug hole center
Axis and vertical direction, oil injector hole central axis and vertical direction have certain less angle, referring to Fig. 1, Fig. 2, spark
The central axis of consent 2 and the central axis of oil injector hole 3 are coplanar；Spark-plug hole central axis is 7.5 degree with vertical direction angle α；
Spark-plug hole central axis is 8 degree with vertical direction angle β.
Further, on cylinder cap and cylinder body fitting surface, spark-plug hole central axis is set with oil injector hole central axis
One determining deviation.In this example, cylinder cap is with cylinder body fitting surface spark-plug hole central axis and oil injector hole central axis spacing A
11mm.Spark-plug hole central axis is 46.8mm with oil injector hole central axis coplanar flat and the distance B of cylinder cap mounting hole 5.
In the present embodiment, square structure mounting groove 1 independently separates with cylinder head oil sump, is matched somebody with somebody by top surface and valve mechanism cover
Sealing is closed, avoids cylinder head oil sump inner fluid from entering square structure mounting groove 1.Fuel injector installation bolt hole 4 is located at oil injector hole 3
Lateral position, and be located at both oil injector hole and spark-plug hole middle part.
