Definitions

  • Engine cooling is performed, for example, to suppress knocking or to ensure reliability.
  • the cooling is performed more than necessary, the cooling loss increases, resulting in a decrease in thermal efficiency, that is, a deterioration in fuel consumption. Therefore, when cooling the engine, it is desirable to increase the cooling performance of the portion where the necessity for cooling is high so that it is possible to achieve both suppression of knocking, ensuring reliability, and reduction of cooling loss.
  • the fifth W / J section 25 is provided on the cylinder head 11.
  • the fifth W / J portion 25 is provided along the longitudinal direction of the engine 10. And a cooling water is distribute
  • the fifth W / J portion 25 is provided in a portion on the opposite side of the combustion chamber E from each of the second W / J portions 22.
  • the fifth W / J unit 25 joins the second W / J units 22 together.

Abstract

L'invention porte sur une structure de refroidissement de moteur équipée de : une première chemise d'eau (21) qui est agencée de manière à faire circuler de l'eau de refroidissement dans la direction longitudinale du moteur (10) et à pouvoir refroidir un orifice d'admission (11a) avec l'eau de refroidissement mise en circulation ; une deuxième chemise d'eau (22) qui est agencée de manière à faire circuler l'eau de refroidissement dans la direction latérale du moteur (10) et à pouvoir refroidir dans une plus grande mesure, au moyen de l'eau de refroidissement mise en circulation, les parties ayant une température relativement plus haute parmi les parties de la culasse (11) qui font face à la chambre de combustion (E) ; et une troisième chemise d'eau (23) qui est agencée de manière à faire circuler de l'eau de refroidissement dans la direction longitudinale du moteur (10) et à pouvoir refroidir un orifice d'échappement (11b) à l'aide de l'eau de refroidissement mise en circulation.
