Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
All cylinders are divided into two groups by V-type diesel exactly, adjacent cylinders is arranged together with certain angle, makes two groups of cylinders be formed with the plane of an angle, from the side the motor that is in the shape of the letter V of cylinder.Height and the length dimension of V-type diesel are little, and automobile is arranged more for convenience.It is convenient to improve discharge capacity and power by expanding cylinder diameter and be suitable for higher number of cylinders.
As shown in Figures 2 to 4, comprise according to the concrete structure of the water inlet structure of the V-type diesel left and right sides water jacket of the specific embodiment of the invention: water jacket water intake 21, dividing plate 22, left side water jacket 23 and right side water jacket 24.Wherein, cooling water enters left side water jacket 23 and right side water jacket 24 thus cool the cylinder of the V-type diesel left and right sides respectively through water jacket water intake 21.Dividing plate 22 is arranged in water jacket water intake 21, thus water jacket water intake 21 is divided into two, when making cooling water enter water jacket from water jacket water intake, two strands of current are isolated into by dividing plate, enter left side water jacket 23 and right side water jacket 24 respectively, and then enter each cylinder, identical in order to ensure the water flow of the left and right sides, the position of dividing plate can adjust and determine according to water jacket CFD (fluid simulation calculating) result of calculation.Even if the resistance of left and right sides water jacket is different like this, can ensures that the water flow of V-type diesel left and right sides water jacket is consistent, thus improve the uniformity of each cylinder water flow.
