Embodiment
To shown in Figure 8, the cylinder head of motor is provided with a water inlet and a water outlet as Fig. 1, and cooling liquid flows by them.Be formed with flow channel between water inlet and water outlet, it also is known as water jacket as the passage of cooling liquid.
The water jacket of cylinder cover for diesel engine comprises cylinder head jacket body 1, the monolithic construction that cylinder head jacket body 1 is formed in one, cylinder head jacket body 1 comprises water jacket front end 4, water jacket rear end 24, water jacket front end 4 is provided with the water hole, last water hole comprises Your Majesty water hole 2 and the inferior water hole 3 of going up, Your Majesty water hole 2 is opened in the bottom surface of water jacket front end 4 near exhaust side, and inferior upward water hole 3 is opened in the middle part of the bottom surface of water jacket front end 4.The air inlet side of water jacket rear end 24 is provided with osculum 25, between water jacket front end 4, water jacket rear end 24, be provided with the water jacket body of four series connection side by side, the i.e. first cylinder water jacket body 8, the second cylinder water jacket body 12, the 3rd cylinder water jacket body 16, the 4th cylinder water jacket body 20, water hole, water jacket body 8,12,16,20 on the primary and secondary, and set gradually and the order connection by flow channel between the osculum 25.Water jacket rear end 24 is higher than water jacket front end 4.Water jacket rear end 24 is the long narrow shape of a saddle, and the cross section of osculum 25 is rounded.
As shown in Figure 2, flow channel comprises flow channel 5,9,13,17,21, middle flow channel 6,10,14,18,22 and current downflow passage 7,11,15,19,23, last flow channel is located at cylinder head jacket near cylinder head exhaust flange face one side, the current downflow passage is located at cylinder head jacket near inlet flange face one side, in flow channel run through between the water jacket front end 4 and the first cylinder water jacket body, successively between tactic water jacket body and the water jacket body, between the 4th cylinder water jacket body and the water jacket rear end, and be connected with last flow channel and current downflow passage.Be communicated with by last flow channel 5, middle flow channel 6, current downflow passage 7 between water hole 2,3 and the first cylinder water jacket body 8 on the primary and secondary; Be communicated with by last flow channel 9, middle flow channel 10, current downflow passage 11 between the first cylinder water jacket body 8 and the second cylinder water jacket body 12; Be communicated with by last flow channel 9, middle flow channel 10, current downflow passage 11 between the second cylinder water jacket body 12 and the 3rd cylinder water jacket body 16; Be communicated with by last flow channel 13, middle flow channel 14, current downflow passage 15 between the 3rd cylinder water jacket body 16 and the 4th cylinder water jacket body 20; Be communicated with by last flow channel 21, middle flow channel 22, current downflow passage 23 between the 4th cylinder water jacket body 20 and the osculum 25,
