Abstract
A car engine body relates to the technical field of an engine body, which comprises an integral-cast crank box and a cylinder body,; wherein, the rate of cylinder center distance and the cylinder diameter is L[0]/ D=1.08-1.18, a loam core is arranged in the space between two cylinders, the corresponding surfaces between the cylinder body and the cylinder are curved faces, and the front and back end surfaces of the crank box apron are provided with strengthening rib. The engine made by the utility model, compared with the engine of the similar category, is smaller in outline dimension, and less in weight, and has a positive significance in reducing the noise pollution of the engines.
Description
Technical field
The technical field that technical solutions of the utility model relate to is an engine body.
Background technique
In the production of automobile, its motor generally adopts multi-cylinder, and the engine body of this multi-cylinder is made up of the crankcase that is cast as one, cylinder block.Particularly in the design of automobile engine body, is the compact degree that solves motor at body, reduces motor boundary dimension, reduces engine weight, adopt less cylinder core distance, and the cylinder core distance/cylinder diameter of single-column type machine body is generally L at present as far as possible
0/ D (two adjacent cylinder core distance/cylinder diameters)=1.20～1.25.Body is the framework of motor, and it shakes under the exciting of combustion gas power and mechanical force, is the main noise source of motor.
Summary of the invention
Technical problem to be solved in the utility model is to design a kind of automobile engine body, to reduce the noise that the vibration generation takes place body, minimizing motor boundary dimension and weight.
The technological scheme of the utility model technical solution problem is: it is made up of the crankcase that is cast as one, cylinder block; The cylinder barrel that its cylinder block is provided with, its cylinder core distance/cylinder diameter are L
0/ D=1.08-1.18, two adjacent cylinder is provided with core chaplet in the interval; With corresponding cylinder surface, cylinder barrel both sides be circular arc camber; Crankcase case skirt front/rear end is provided with stiffening rib, and the wide ratio of muscle height and muscle is between the 1-3.Cylinder barrel is provided with cooling water hole in the interval.
Owing to adopt technique scheme, distance is between the 6-10mm only between the utility model two adjacent casing walls; The motor that the utility model is made is compared with similar motor, and weight reduces by 5 kilograms, and boundary dimension reduces 10mm, and noise reduces by 1.5 decibels.The engine cooling performance is further enhanced.

Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is that the utility model is along crankcase case skirt ear end face schematic representation;
Fig. 4 is that the utility model is along crankcase case skirt front-end face schematic representation;
The B-B place horizontal cross of Fig. 5 Fig. 3;
Among the figure: 1, cylinder block; 2, crankcase; 3, cylinder barrel; 4, core chaplet; 5, cooling water hole; 6-11, stiffening rib.
Embodiment
In conjunction with Fig. 1, Fig. 2, a kind of automobile engine body, it is made up of the crankcase 2 that is cast as one, cylinder block 1.Distance is 8mm between cylinder barrel 3 walls that cylinder block 1 is provided with, and cylinder core distance/cylinder diameter is L
0/ D=1.11.Present embodiment has been abandoned the design of water jacket between two adjacent cylinder barrels, makes for ease of foundry goods, is provided with core chaplet 4 (with reference to Fig. 2) in the interval of two adjacent cylinder barrels 3.For solving the reinforcement cooling problem of motor, be provided with cooling water hole 5 (with reference to Fig. 2) in the interval of two adjacent cylinder barrels 3, cooling water hole 5 is arranged in a crossed manner.With reference to Fig. 5, with cylinder barrel 3 both sides corresponding cylinder bodies 1 surface be circular arc camber, this design, not only can reduce casting stress increases body rigidity but also can reduce radiated noise.
In conjunction with Fig. 3, Fig. 4, Fig. 3 is the left view of Fig. 1, and Fig. 4 is the right elevation of Fig. 1, and present embodiment is provided with stiffening rib 6,7 at 2 casees skirt front-end faces of crankcase; Press Fig. 3 scheme, present embodiment is provided with stiffening rib 8,9,10,11 in the crankcase rear end; Utilization is provided with the mode of stiffening rib in 2 casees skirt front end and back end of crankcase, increased by 2 casees skirt transverse bending of crankcase rigidity, suppresses the engine body noise with rigidity control method.Stiffening rib 6,7,8,9,10,11, the wide ratio of muscle height and muscle is 1.1.
Design of the present utility model is applicable to the manufacturing of single-bank engine body.
