Abstract
Four jar diesel engine organisms with guide plate includes: organism, guide plate, the guide plate has been arranged in the oil cooler of organism internal cooling water course side, the guide plate is on a parallel with cylinder central plane direction, it extends to machine body rear end fourth jar center to follow organism front end water inlet inboard, its thickness is the same with the cylinder body wall thickness, divide into cold ware cooling cavity of machine and cylinder liner cooling cavity with organism internal cooling water course, and arranged the rectangle in per two jar middle parts of guide plate and crossed the mouth of a river, its length is 50 2mm, the width is 20 2mm, make cold ware cooling cavity of machine and cylinder liner cooling cavity be linked together through crossing the mouth of a river and guide plate afterbody passageway. Through increasing the guide plate for cooling water adequate cooling oil cooler improves oil cooler's heat -sinking capability, has improved heat exchange coefficient and surface velocity and flow, has effectively reduced the machine oil temperature.
Description
Technical field
The utility model belongs to field of internal combustion engine, relates to a kind of four-cylinder diesel engine body with guide plate.
Background technique
At present, in the widely used four-cylinder diesel engine body of China, after cooling water flow enters body, meeting cross flow is to the bottom surface of whole cooling jacket, then upwards flows and cools built-in machine cooler and cylinder sleeve simultaneously, finally flows out body and enters cylinder cap.This type of cooling can cause the surface film thermal conductance of built-in machine cooler and surface water Flow Velocity to occur the situation that height rear end, front end is low, and diesel engine lubricating oil cooling effect is not good.And cooling degree around each cylinder cylinder sleeve is uneven, cooling effectiveness is lower, brings harm to the normal operation of diesel engine.
model utility content:
The purpose of this utility model is to provide a kind of four-cylinder diesel engine body with guide plate, by changing the form in body inner cooling water road, takes into account the factor such as uniformity, cylinder block strength of machine cooler cooling capacity, cylinder sleeve cooling, Optimization of Diesel Engine cooling performance.
The technical solution of the utility model is: with the four-cylinder diesel engine body of guide plate, comprising: body, guide plate; Guide plate is furnished with in the machine oil cooler side of internal body cooling water channel, guide plate is parallel to direction, cylinder axis face, body rear end the 4th cylinder central position is extended to from the inner side of body front end water intake, its thickness is identical with cylinder body wall thickness, body inner cooling water road is divided into machine cooler cooling chamber and cylinder sleeve cooling chamber, and the rectangular mouth of a river is excessively furnished with in every two cylinder intermediate portions of guide plate, its length is 50 ± 2mm, width is 20 ± 2mm, makes machine cooler cooling chamber and cylinder sleeve cooling chamber pass through the mouth of a river and is connected with the passage of guide plate afterbody.
The utility model can reach following good effect after adopting technique scheme: by increasing guide plate, make cooling water can abundant cooling machine oil cooler, improve the heat dissipation potential of machine oil cooler, improve the coefficient of heat transfer and surface velocity and flow, effectively reduce oil temperature.Then cooling water enters cooling chamber around cylinder sleeve from the passage crossing the mouth of a river and guide plate afterbody, and make each cylinder cylinder sleeve cooling uniformity have obvious improvement, heat exchange amount is also more even.
accompanying drawing illustrates:
Fig. 1 is the four-cylinder diesel engine housing construction horizontal cross of the utility model with guide plate;
Fig. 2 is the four-cylinder diesel engine housing construction vertical sectional view of the utility model with guide plate.
embodiment:
Below in conjunction with accompanying drawing, the utility model will be further described.As shown in Fig. 1 ~ 2, a kind of diesel-engine body, a kind of four-cylinder diesel engine wet type body, comprising: body 1, guide plate 2, when existing body boundary dimension of the same type is substantially constant, guide plate 2 is furnished with in the machine oil cooler side of body 1 internal cooling water channel, guide plate 2 is parallel to direction, cylinder axis face, cylinder central position, body 1 rear end the 4th is extended to from the inner side of body 1 front end water intake 3, its thickness is identical with cylinder body wall thickness, body 1 inner cooling water road is divided into machine cooler cooling chamber 4 and cylinder sleeve cooling chamber 5, and three rectangular mouths of a river 6 are excessively furnished with altogether in every two cylinder intermediate portions of guide plate 2, its length L is 50 ± 2mm, width W is 20 ± 2mm, make machine cooler cooling chamber 4 and cylinder sleeve cooling chamber 5 pass through the mouth of a river 6 to be connected with the passage 7 of guide plate 2 afterbody.After cooling water enters body 1 from body front end water intake 3, first cooling machine oil cooler, while almost all mulch-laying machine oil cooler carries out the cooling of high flow rate, large discharge, the cooling chamber around cylinder holes is entered from three passages 7 crossing the mouths of a river 6 and guide plate 2 afterbody, enclosed cooling is carried out to each cylinder of four-cylinder diesel engine, thus effectively reduces the heat load of cylinder sleeve.
