Abstract
The present invention provides a cooling water channel structure between engine crankcase cylinders, which comprises a crankcase, a cylinder pad and a cylinder cap. The crankcase is installed with a crankcase cylinder hole water jacket. The cylinder cover is installed with a cylinder cover water jacket. A cooling water channel is longitudinally installed between each two cylinder holes of crankcase. One end of cooling water channel is communicated with the crankcase cylinder hole water jacket. The other end is communicated with the cylinder cover water jacket through a cylinder pad water hole. The cooling water channel is composed of the water channel which is communicated with the crankcase cylinder hole water jacket and the water channel that is communicated with the cylinder cover water jacket through cylinder pad water hole. Two water channels and the top surface of crankcase are arranged with an included angle. The two water channels are communicated with each other at the bottom end. Each water channel equally comprises two segments of phiA water channel and phiB water channel. The structure of the invention can effectively reduce the temperature between the cylinder holes of crankcase and the temperature of nose bridge area of cylinder cap, reduces the temperature difference of periphery of cylinder jacket and reduces the thermal deformation of cylinder jacket thereby increasing the durability and reliability of cylinder jacket and reducing the consumption amount of engine grease oil and exhaust discharge.
Description
Technical field
The present invention proposes a kind of cooling technology of engine crankcase, is specifically related to the design of cooling channel between the engine crankcase cylinders hole.
Background technique
As depicted in figs. 1 and 2, usually the cooling water channel of engine crankcase is that a part of cooling water flows to the crankcase rear end from crankcase 103 front end edge crankcase water jackets 107, a part flows into cylinder cap water jacket 113 through the water hole of cylinder pad 102,115 is cylinder sleeve among the figure, arrow is the flow of cooling water direction, and as seen it is not provided with vertical cooling water channel and cools off between two cylinder holes 114.This kind cooling structure of crankcase can satisfy the motor of less heat load.And for more compact structure, the motor that power per liter is higher and oil consumption is littler then is not suitable for.
Summary of the invention
Of the present invention at the deficiency of cooling off between the crankcase cylinders hole, a kind of cooling water channel structure between engine crankcase cylinders is provided, has connected crankcase and the cylinder cap water jacket reduces temperature between the crankcase cylinders hole by two sections Ф A water channels, two sections Ф B water channels and cylinder pad water hole.
Technological scheme of the present invention is as follows:
A kind of cooling water channel structure between engine crankcase cylinders comprises crankcase, cylinder pad and cylinder cap, and crankcase is provided with crankcase cylinders hole water jacket, and cylinder cap is provided with the cylinder cap water jacket; It is characterized in that: be vertically arranged with cooling water channel between each cylinder hole of crankcase, cooling water channel one end is communicated with crankcase cylinders hole water jacket, and the other end is communicated with the cylinder cap water jacket by cylinder pad water hole.
Described cooling water channel is formed by the water channel that is communicated with crankcase cylinders hole water jacket with the water channel that is communicated with the cylinder cap water jacket by cylinder pad water hole, and two water channels and crankcase end face all are angle and arrange that two water channels are interconnected in the bottom.Each water channel all comprises two sections in Ф A water channel and two sections and Ф B water channel again.
The component that motor need cool off are mainly by crankcase, and cylinder pad and cylinder cap are formed, and the cylinder pad mainly plays sealing gas, cooling water and regulates the effect that current distribute.Form a cooling water passage that cools off high heat load zone between the crankcase cylinders hole by cooling water flow through Ф A, Ф B cooling water channel, cylinder pad water hole, cylinder cap water jacket between crankcase cylinder hole water channel, the crankcase cylinders hole, realize reducing the purpose of crankcase, cylinder cap high heat load regional temperature.
Above structure can effectively reduce between the crankcase cylinders hole and cylinder cap bridge of the nose district temperature, reduces cylinder sleeve temperature approach all around, improves the durable and reliability of cylinder sleeve thereby reduce the cylinder sleeve hot shaping, reduces engine motor oil consumption and toxic emission.

Embodiment
Referring to Fig. 3, the present invention includes crankcase 103, cylinder pad 102 and cylinder cap 101, crankcase 103 is provided with crankcase cylinders hole water jacket 107, and cylinder cap is provided with cylinder cap water jacket 113.The present invention further is vertically arranged with cooling water channel between each cylinder hole of crankcase 103, cooling water channel one end is communicated with crankcase cylinders hole water jacket 107, and the other end is communicated with cylinder cap water jacket 113 by cylinder pad water hole.
Specific practice is, at first between 103 two cylinder holes of crankcase drilling one first epimere Ф A water channel 108, Ф A diameter is Ф 3～Ф 6mm, the first epimere Ф A water channel 108 and crankcase end face be the C1 angle, C1 is 25 °～45 °, and length L 1 is 9～30mm; The drilling first hypomere Ф B water channel 109 again in the first epimere Ф A water channel, 108 bottoms, its length L 2 is 10～25mm, Ф B diameter is Ф 2～Ф 6mm.Simultaneously, be the C2 angle from the crankcase end face drilling second epimere Ф A water channel 111, the second epimere Ф A water channels 111 with the crankcase end face, it is that length L 3 is 10～45mm that C2 is 20 °～45 °; The drilling second hypomere Ф B water channel 110 again in the second epimere Ф A water channel, 111 bottoms, its length L 4 is 10-30mm.Communicate with cylinder pad water hole 112 at the second epimere Ф A water channel 111, cylinder pad water hole 112 communicates with cylinder cap water jacket 113, and whole coolant flow direction is shown in the direction of arrow among the figure.
