Abstract
The utility model relates to an engine regulating the current distribution in a water jacket of an internal combustion engine. The multi-cylinder internal combustion engine is provided with water outlet pores with different diameters, and the cooling water enters a water hole in a cylinder gasket and the water hole in a cylinder cap through the water outlet pores of a plurality of cylinders, and at least two cylinders are provided with water outlet pores with different diameters which are arranged at the corresponding place of the horizontal cylinders. By adjusting the flow rate of the water holes, the current distribution in the water jacket of the internal combustion engine can be optimized. The different apertures of the water holes of the cylinders are determined by the means of computational fluid dynamics and the test method. The utility model has the advantages of obvious effect of optimizing the current distribution in the water jacket, simple manufacture and reliable structure.
Description
One, technical field
The utility model relates to a kind of water cooling internal combustion (IC) engine airframe.
Two, technical background
Along with to efficient, oligosaprobic internal-combustion engine active demand, requirements at the higher level are proposed for the design of I. C. engine water cooling system.The task of I. C. engine water cooling system is that the assurance internal-combustion engine is worked under suitable temperature conditions.Cooling water of internal combustion engine flows and drives by water pump, and water flow is crossed conference and enlarged markedly pump power consumption; The internal-combustion engine different parts to cylinder head " bridge of the nose district " and the close higher zone of firepower bank face operating temperature of body, needs enough coolings avoid local superheating to cooling system demand difference in addition, needs insulation for partial structurtes.Under limited water flow,, need take effective current mean of calculating for guaranteeing reasonably current distribution in the internal combustion (IC) engine airframe water jacket.At concrete Structure of Internal-Combustion Engine arrangement, can adopt the method for adjusting the seal ring aperture or adjusting aperture, head gasket water hole to adjust current distribution in the water jacket in the comparatively advanced water jacket design.Adjust the method in seal ring aperture, the needs that distribute according to current are taked the seal ring of different diameter of bores, and this mode assembly process process is poor, and in maintenance in batches, dress is wrong easily in the assembling, seldom adopts in the batch process.It is more to regulate the method employing of aperture, head gasket water hole, but has following situation inapplicable: 1. for the structural design that top board is arranged between body and cylinder head.2. head gasket complex structure, difficulty of processing is big, leaks easily, leaks gas.3. head gasket itself is very thin, take to control the water hole measure after, can cause the throttle orifice local velocity too high, local negative pressure is low excessively, if be lower than water saturation pressure and will cause local cavitation.The utility model is body osculum size is taked the adjusting measure, reaches to optimize the purpose that current distribute in the water jacket, and structural design is simple, reduces number of spare parts, and is cheap for manufacturing cost, effective.
Three, summary of the invention
The technical problems to be solved in the utility model provides a kind of body that current distribute in the water jacket of internal combustion engine of regulating, and this body can be suitable for any type, and assembly process process is strong, and simple in structure, easy operating.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of body of regulating current distribution in the water jacket of internal combustion engine, multi-cylinder engine cooling water each cylinder osculum on body, enter gentle cylinder cap water hole, head gasket water hole, be distributed in each the cylinder osculum on the multi-cylinder body, have two cylinders at least or the osculum aperture at horizontal each cylinder opposite position place is inequality successively more than two cylinders.
The body that current distribute in the above-mentioned adjusting water jacket of internal combustion engine, be distributed in the osculum of six cylinders on the body, inequality in the osculum aperture at horizontal each cylinder opposite position place successively, horizontal six cylinders in the aperture of first housing osculum are followed successively by 8 respectively, 7,7,7,6,6 millimeters, horizontal six cylinders in the aperture of second housing osculum are followed successively by 8 respectively, 7,7,6,6,6 millimeters, horizontal six cylinders in the aperture of the 3rd body osculum are followed successively by 17 respectively, 9,9,8,8,8 millimeters, horizontal six cylinders in the aperture of the 4th body osculum are followed successively by 17 respectively, 14,9,9,8,8 millimeters.
The processing of body osculum can select for use the cutter of different-diameter directly to process realization in common body osculum course of working.The beneficial effects of the utility model are: by adjusting each water hole water flow in the different osculum aperture of body end face processing, current distribute in the water jacket thereby optimize, and are strong to the regulating power of current.
Four, description of drawings
Fig. 1 is for regulating the body schematic representation that current distribute in the water jacket of internal combustion engine, and Fig. 2 is the plan view of Fig. 1.
Among the figure: 1 is the cylinder head water hole, and 2 is body, and 3 is the head gasket water hole, and 4 is first housing osculum, and 5 is second housing osculum, and 6 is the 3rd body osculum, and 7 is the 4th body osculum.
Five, preferred forms
Preferred forms of the present utility model as shown in Figure 1, 2, a kind of body 2 of regulating current distribution in the water jacket of internal combustion engine, cooling water is through the osculum of body 2, enter 3 gentle cylinder cap water holes 1, head gasket water hole, be distributed in each the cylinder osculum on the body 2, all inequality in the osculum aperture at horizontal each cylinder opposite position place.The osculum aperture design adopts the computation fluid dynamics method to draw by analog computation, and the design later stage can adopt test method that the aperture is adjusted.The processing of body osculum can select for use the cutter of different-diameter directly to process realization in the former body osculum course of working.Realize current distribution optimization in the whole water jacket by adjusting different body osculum apertures, directly choosing principle for different osculums is: laterally take different osculums to distribute in order to the current of adjusting between each cylinder between each cylinder for motor, for advancing of each cylinder, the exhaust both sides take different apertures in order to form pressure difference in both sides, increase bridge of the nose district and body near the higher zone of firepower bank face operating temperature, have enough coolings and avoid local superheating, and under limited water flow, take effectively to regulate the means of flow, guarantee reasonably current distribution in internal combustion (IC) engine airframe 2 water jackets.When internal-combustion engine be cylinder bore be 121 millimeters six cylinders at a high speed in during power diesel engine, each cylinder that is distributed on the body 2 has 4 osculums that the aperture is different, simultaneously successively on horizontal six cylinders the osculum aperture at opposite position place also inequality, horizontal six cylinders in the aperture of first housing osculum 4 are followed successively by 8 respectively, 7,7,7,6,6 millimeters, horizontal six cylinders in the aperture of second housing osculum 5 are followed successively by 8 respectively, 7,7,6,6,6 millimeters, horizontal six cylinders in the aperture of the 3rd body osculum 6 are followed successively by 17 respectively, 9,9,8,8,8 millimeters, horizontal six cylinders in the aperture of the 4th body osculum 7 are followed successively by 17 respectively, 14,9,9,8,8 millimeters.
The utility model processing technology is simple, reliable in structure, and between body 2 and cylinder head, have head gasket, top board, the isostructural type of top plate pads and still can realize, do not influence the sealing problem of head gasket for circulating water and combustion gas.
