Definitions

  • This invention relates to a cooling structure for an engine, and more particularly to a cooling structure for a water-cooling type engine.
  • a conventional water-cooling type engine includes a cylinder with a first water passage, a cylinder head with a second water passage, and a sealing gasket disposed between the cylinder and the cylinder head.
  • the first and second water passages extend in a circumferential direction so as to constitute a water jacket.
  • the sealing gasket has an outer peripheral portion that is formed with a plurality of holes, through which cooling water can flow from the first water passage in the cylinder to the second water passage in the cylinder head. As such, the cooling water flows from a water inlet of the first water passage in the cylinder to a water outlet of the second water passage in the cylinder head through the holes in the sealing gasket.
  • the cooling water flows from the water inlet of the first water passage into the water outlet of the second water passage via a plurality of paths that have different lengths, thereby resulting in relatively uneven cooling in the engine, which can lead to quick deformation of the engine.
  • the object of this invention is to provide a water-cooling type engine that is formed with a single cooling-water path in a cylinder and a cylinder head so that the cooling of the engine is relatively uniform.
  • a water-cooling type engine includes a cylinder, a cylinder head, and a sealing gasket disposed between the cylinder and the cylinder head.
  • a water passage arrangement is provided so as to permit cooling water to flow from a water inlet in the cylinder to a water outlet in the cylinder or the cylinder head along a single flowing path. As such, the cooling of the engine is relatively uniform.
  • the first preferred embodiment of a water-cooling type engine is shown to include a cylinder 2, a cylinder head 3 disposed on the cylinder 2, a sealing gasket 4 disposed between the cylinder 2 and the cylinder head 3, and an auxiliary water conduit 5.
  • the cylinder 2 includes an inner cylinder wall 22 that defines a cylindrical chamber 222, and an outer cylinder wall 23 that is formed integrally with the inner cylinder wall 22 at upper and lower ends thereof so as to define a first water passage 20 between the inner and outer cylinder walls 22, 23.
  • the cylinder head 3 is formed with a second water passage 30 that has a water inlet 301 and a water outlet 302.
  • the cylinder 2 further includes a radially extending spacer wall 21 that has a radial inner end 211 that is formed integrally with the inner cylinder wall 22, and a radial outer end 212 that is formed integrally with the outer cylinder wall 23.
  • the first water passage 20 in the cylinder 2 has a water inlet 201 permitting introduction of cooling water therethrough, and a water outlet 202.
  • the auxiliary water conduit 5 is connected to the cylinder 2 and the cylinder head 3, and is in fluid communication with the water outlet 202 of the first water passage 20 in the cylinder 2 and the water inlet 301 of the second water passage 30 in the cylinder head 3.
  • the water inlet and outlets 201, 202 in the cylinder 2 are adjacent to and are located on two sides of the spacer wall 21, respectively, so that the cooling water can flow from the water inlet 201 of the first water passage 20 in the cylinder 2 to the water outlet 202 of the first water passage 20 in the cylinder 2 along a circumferential direction.
  • the cooling water further flows from the water outlet 202 of the first water passage 20 in the cylinder 2 into the water inlet 301 of the second water passage 30 in the cylinder head 3, and exits from the engine through the water outlet 302 of the second water passage 30 in the cylinder head 3.
  • Fig. 3 shows the second preferred embodiment of a water-cooling type engine according to this invention, which is similar to the first preferred embodiment in construction except that this embodiment includes two cylinders 2, and an inner cylinder wall 22 defining two cylindrical chambers 222.
  • Figs. 4 and 5 show the third preferred embodiment of a water-cooling type engine according to this invention, which is similar to the first preferred embodiment in construction except that the water inlet 301 of the second water passage 30 in the cylinder head 3 is in fluid communication with the water outlet 202 of the first water passage 20 via a hole 44 in the sealing gasket 4 instead of through the auxiliary water conduit 5 (see Fig. 1).
  • Fig. 6 shows the fourth preferred embodiment of a water-cooling type engine according to this invention, which is similar to the third preferred embodiment in construction except that this embodiment includes two cylinders 2, and an inner cylinder wall 22 defining two cylindrical chambers 222.
  • the fifth preferred embodiment of a water-cooling type engine is shown to include a cylinder 2, a cylinder head 3 disposed on the cylinder 2, and a sealing gasket 4 disposed between the cylinder 2 and the cylinder head 3.
  • the cylinder 2 includes an inner cylinder wall 22 that defines a cylindrical chamber 222, and an outer cylinder wall 23 that is formed integrally with the inner cylinder wall 22 at upper and lower ends thereof so as to define a first water passage unit 20 between the inner and outer cylinder walls 22, 23.
  • the cylinder head 3 is formed with a second water passage 30 that has a water inlet 301 and a water outlet 302.
  • the cylinder 2 further includes two aligned, radially extending spacer walls 21, each of which has a radial inner end 211 that is formed integrally with the inner cylinder wall 22, and a radial outer end 212 that is formed integrally with the outer cylinder wall 23.
  • the first water passage unit 20 in the cylinder 2 is divided by the spacer walls 21 into a front passage portion 203 and a rear passage portion 204 that are spaced apart from each other.
  • the front passage portion 203 has an inlet end (203A) distal to the cylinder head 3, an outlet end (203B) proximate to the cylinder head 3, and a water inlet 201 that is adjacent to the inlet end (203A) and that permits introduction of the cooling water therethrough.
  • the rear passage portion 204 has an inlet end (204A) proximate to the cylinder head 3, an outlet end (204B) distal to the cylinder head 3, and a water outlet 202 that is adjacent to the outlet end (204B) and that permits discharging of the cooling water from the engine therethrough.
  • the sealing gasket 4 is formed with a front hole 44 in fluid communication with the outlet end (203B) of the front passage portion 203 of the first water passage unit 20 and the water inlet 301 of the second water passage 30 in the cylinder head 3, and a rear hole 44' in fluid communication with the water outlet 302 of the second water passage 30 in the cylinder head 3 and the inlet end (204A) of the rear passage portion 204 of the first water passage unit 20, thereby permitting flow of the cooling water from the water inlet 201 of the front passage portion 203 to the water outlet 202 of the rear passage portion 204 through the second water passage 30.
  • Fig. 9 shows the sixth preferred embodiment of a water-cooling type engine according to this invention, which is similar to the fifth preferred embodiment in construction except that this embodiment includes two cylinders 2, and an inner cylinder wall 22 defining two cylindrical chambers 222.
