Description
One, technical field:
The utility model relates to a kind of cylinder head of multi-cylinder diesel engine, relates in particular to a kind of cylinder head of two cylinder diesel engine.
Two, background technique:
The cylinder core distance that generally uses is 130 millimeters a two cylinder diesel engine at present, its main specifications has 2100 and 2105 etc., its cylinder bore is 105 millimeters to the maximum, when rated speed is 2500r/min, its 12h output power is about 27kW, along with haulage vehicle, tractor, engineering machinery etc. are to the power character of its supporting two cylinder diesel engine and the progressively improve of exhaust index requirement, requirement can be existing 2100, on the basis of 2105 two cylinder diesel engines, promptly at cylinder core distance, under the constant situation such as stroke, can further improve the output power of two cylinder diesel engine, simultaneously can reduce the discharging of diesel engine 12h nominal power under the 27-28kW operating mode, according to the diesel engine design principle, realize above-mentioned requirements, then should increase the cylinder diameter of diesel engine, increase the discharge capacity of diesel engine.And be on 130 millimeters the two cylinder diesel engine at existing cylinder core distance, be difficult to realize the requirement of above-mentioned expansion cylinder, because in existing 2100,2105 two cylinder diesel engines, be in the system of coordinates of rectangular coordinates initial point with first cylinder axis, the position coordinate of ten cylinder head bolt settings on the diesel engine is:
Can learn that from last table the distance of the centre distance first cylinder axis O1 in No. 5 holes is 73.78 millimeters, the distance of the centre distance first cylinder axis O1 in 2 and No. 4 holes is 76.32 millimeters; The distance of No. 8 hole centre distance second cylinder axis O2 is 73.78 millimeters, and the distance of the centre distance second cylinder axis O2 in 4 and No. 9 holes is 76.32 millimeters; Want further to enlarge the cylinder diameter of two cylinders of above-mentioned two cylinder diesel engine, its cylinder diameter is expanded to greater than 105 millimeters less than between 110 millimeters, must be from the distributing position of new layout cylinder head bolt, make 2,4, No. 5 cylinder head bolts install that the distance apart from the first cylinder axis O1 increases in the screw, same 4,8, No. 9 cylinder head bolts are installed screw also will be increased apart from the distance of the second cylinder axis O2.
Three, summary of the invention:
In order to make cylinder core distance is that 130 millimeters double cylinder diesel function adapts to above-mentioned supporting requirement, problem to be solved in the utility model is: how under the constant condition of the boundary dimension of the cylinder head of existing two cylinder diesel engine 2100,2105 and cylinder core distance, by position and the size that changes the cylinder head bolt mounting hole again, rearranging of air flue and water channel is to adapt to the expansion cylinder requirement of above-mentioned two cylinder diesel engine.
The utility model is to solve the problems referred to above by following technical solution:
A kind of cylinder core distance is the cylinder head of 130 millimeters two cylinder diesel engine, comprise cylinder head bolt mounting hole, intake duct, air outlet flue, suction valve cone hole, exhaust valve seat hole, oil nozzle mounting hole and cooling water channel hole, be in the system of coordinates of rectangular coordinates initial point with the first cylinder axis O1, the position coordinate of above-mentioned each cylinder head bolt mounting hole setting is:
The coordinate position and the shape of suction valve cone hole, exhaust valve seat hole, oil nozzle mounting hole are identical with existing cylinder head, and the shape in cooling water channel hole and inlet and outlet road is along with adaptations is made in the variation of cylinder head bolt mounting hole.
As to further improvement of the utility model, the diameter of described bolt cylinder mounting hole is 12.5～15.5 millimeters.
Because the distributing position to each cylinder head bolt mounting hole on the cylinder head of existing 2100,2105 two cylinder diesel engines has been done to rearrange, for further expanding cylinder, above-mentioned two cylinder diesel engine provides necessary space, can make existing 2100,2105 two cylinder diesel engines further expand cylinder to 106～110 millimeter, thereby improve its output power; While can also make the diesel engine behind the expansion cylinder be further improved in the discharging of exporting under the power condition that 12 one hour rated outputs are 27～28kW.
