Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Shown in Fig. 1,2 or 3, the utility model includes crankcase 1, cylinder block 2, cylinder head 3 and cylinder head 4, it is characterized in that:
A, cylinder head 3 are provided with cooling water passage 5, and a port of this cooling water passage 5 is positioned on the lower end surface with the corresponding cylinder head 3 in cylinder block 2 upper-end surfaces, and another port is provided with water nozzle 13;
Be provided with cooling water cyclic cavity 7 in b, the cylinder block 2, the side of cylinder block is provided with and the corresponding technology opening 8 of cooling water cyclic cavity, be provided with sealing cover 9 in the position accordingly with technology opening 8, the side of cylinder block 2 or sealing cover 9 are provided with the water nozzle 6 that communicates with cooling water cyclic cavity 7, cylinder block 2 is provided with the water channel 10 excessively that communicates with cooling water cyclic cavity 7, and this upper end-hole of crossing water channel 10 is positioned at the lower end mouth of cooling water passage 5 and communicates.
As shown in Figure 6, technology opening in the utility model is the opening that is produced when empty in the cylinder block in process of production, the residing position of this opening can be on the cylinder block any can the side of opening on, the number of opening is one at least, and the effect that sealing cover is set is for the sealing to the cooling water cyclic cavity.
