Abstract
(EN)
Provided is an engine cooling structure, comprising a water pump (1), a cylinder liner (3), a cylinder block (6), a cylinder head (8), and a water outlet pipe (7); a cylinder block water chamber is formed between the cylinder block (6) and the cylinder liner (3); the cylinder block water chamber is located on the side of the body (6) adjacent to the cylinder head (8); the cylinder block water chamber comprises an upper water chamber (4) and a lower water chamber (5), arranged sequentially from top to bottom, and the flow area of the upper water chamber (4) is smaller than that of the lower water chamber (5); the cylinder block (6) has a cylinder block water distribution chamber (2), and the cylinder block water distribution chamber (2) is located on the side of a cooling water chamber; the water outlet of the water pump (1) is sequentially in communication with the cylinder block water distribution chamber (2), the cylinder block water chamber, the water chamber of the cylinder head (8), and the water chamber of the water outlet pipe (7); also disclosed is an engine. The engine cooling structure and engine reduce the difficulty of casting the cylinder block and improve the compactness of the structure.

L'invention concerne une structure de refroidissement de moteur, comprenant une pompe à eau (1), une chemise de cylindre (3), un bloc-cylindres (6), une culasse (8), et un tuyau de sortie d'eau (7). Une chambre d'eau de bloc-cylindres est formée entre le bloc-cylindres (6) et la chemise de cylindre (3), est située sur le côté du corps (6) adjacent à la culasse (8), et comprend une chambre d'eau supérieure (4) et une chambre d'eau inférieure (5), disposées de manière séquentielle de haut en bas, et la zone d'écoulement de la chambre d'eau supérieure (4) est inférieure à celle de la chambre d'eau inférieure (5). Le bloc-cylindres (6) comporte une chambre de distribution d'eau de bloc-cylindres (2) qui est située sur le côté d'une chambre d'eau de refroidissement. La sortie d'eau de la pompe à eau (1) est en communication séquentielle avec la chambre de distribution d'eau de bloc-cylindres (2), la chambre d'eau de bloc-cylindres, la chambre d'eau de la culasse (8), et la chambre d'eau du tuyau de sortie d'eau (7). L'invention concerne également un moteur. La structure de refroidissement de moteur et le moteur réduisent la difficulté de moulage du bloc-cylindres et améliorent la compacité de la structure.
