Abstract
The utility model particularly relates to a water cooling four-cylinder diesel engine body, in particular to a four-cylinder diesel engine body provided with a water distribution channel. The four cylinder diesel engine body provided with four cylinder sleeve water cavities is provided with the tubular water channel at the outer sides of the cylinder sleeve water cavities on the engine body, and water outlets communicated with each other are arranged between the tubular water channel and the rear ends of the four adjacent cylinder sleeve water cavities; and a front water outlet is arranged between the front end of the first cylinder sleeve water cavity and the tubular water channel, and the diameter of the front water outlet is 8mm. In the four-cylinder diesel engine body, by adding the water outlet between the front end of the first cylinder sleeve water cavity and the water distribution channel, the flow distribution is optimized, the temperature and quantity of water flowing to each cylinder sleeve are kept to be uniform and consistent, the heat dissipation of the whole engine is uniform, the faults of cylinder score, gas valve breakage and the like of the diesel engine are reduced, and the service life of the whole engine is prolonged.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, is specifically related to water cooling four-cylinder diesel engine body.
Background technique
Diesel engine can produce great amount of heat when work, in order to guarantee diesel oil function long time continuous working, just must take cooling method to diesel engine, makes its operating temperature remain on a proper state.Adopt water-cooled diesel-engine body inside all to be furnished with water cavity at present; The four-cylinder body of common band cloth water jacket has water outlet in each cylinder rear end; The water that certain pressure and flow velocity are arranged that is promptly pumped by water pump flows into water cavity from the cloth water channel; Through each cylinder cylinder sleeve, the entering cylinder head is flowed out from the body top board in each cylinder cylinder sleeve cooling back.There is following major defect in this type of body: the cooling water at the first cylinder cylinder sleeve front end position is not enough; The cooling water of cylinder sleeve bottom all is to flow through through the water outlet of upper end to flow to the first cylinder cylinder sleeve lower end successively from the 4th cylinder cylinder sleeve lower end again behind each cylinder, and adding each cylinder sleeve place top board all has several water holes that leads to cylinder head, and these holes can make cooling water flow before next cylinder sleeve, divide the part of pouring off; The water yield that flows to the back cylinder sleeve like this can be fewer and feweri; Water temperature also can be increasingly high, causes the complete machine heat radiation uneven, and first cylinder heat radiation situation is the poorest; The component state is inconsistent; Reduce the Diesel Engine Complete Machine performance, a fault such as serious meeting makes diesel engine generation scuffing of cylinder bore, die shortens diesel engine working life.
The model utility content
In order to solve the even problem of inhomogeneous cooling that existing diesel cylinder body water cavity exists, the utility model provides a kind of four-cylinder diesel engine body that between the first cylinder cylinder sleeve water cavity front end and cloth water channel, increases water outlet.
The technical solution that realizes above-mentioned purpose is following:
Band cloth water channel four-cylinder diesel engine body; The body 1 that comprises four-cylinder diesel engine with cylinder sleeve water cavity 3; Its length direction, on the body 1 in cylinder sleeve water cavity 3 outsides, be provided with a tubulose water channel 5 along body; One end of tubulose water channel 5 is a water intake 2, is provided with the water outlet 6 that is communicated with between tubulose water channel 5 and four adjacent cylinder sleeve water cavity 3 rear ends; Improvement is: water outlet 4 before between the first cylinder sleeve water cavity front end and tubulose water channel 5, being provided with; The diameter of water outlet 4 is 8 millimeters before said.
The useful technique effect of the utility model is: through setting up the water outlet between a cylinder cylinder sleeve water cavity front end and the cloth water channel; Optimize the current distribution, made the water temperature of the water that flows to each cylinder cylinder sleeve, the water yield keep uniformity, ensured the complete machine heat radiation evenly; It is identical to keep each cylinder working state; Stablize the complete machine performance, the generation of a fault such as reduce the diesel engine scuffing of cylinder bore, die prolongs machine life.
Description of drawings
Fig. 1 is the structural representation plan view of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
Embodiment:
Band cloth water channel four-cylinder diesel engine body; The body 1 that comprises four-cylinder diesel engine with cylinder sleeve water cavity 3; Its length direction, on the body 1 in cylinder sleeve water cavity 3 outsides, be provided with a tubulose water channel 5 along body; One end of tubulose water channel 5 is a water intake 2, is provided with the water outlet 6 that is communicated with between tubulose water channel 5 and four adjacent cylinder sleeve water cavity 3 rear ends; Improvement is: water outlet 4 before between the first cylinder sleeve water cavity front end and tubulose water channel 5, being provided with.
Each water outlet diameter is 12mm in four water outlets 6 of said connection four cylinders, and preceding water outlet 4 diameters are 8mm; Through five water outlets, current can cool off each cylinder cylinder sleeve through two paths.Tubulose water channel water intake 2 directly links to each other with pump outlet, and the water that water pump pumps directly gets into tubulose water channel 5, because any cylinder sleeve water cavity of not flowing through, this just can keep water temperature self-consistentency in the cloth water channel water cavity; Satisfy complete machine to the uniform requirement of dispelling the heat, eliminate the bad problem of first cylinder cylinder sleeve front end cooling.Thereby reach the purpose of stablizing the complete machine performance, improving whole aircraft reliability.
