  • Patent number: 8464683
    Abstract: An engine balancer system is provided in which a balancer housing (17) disposed so as to face an oil pan beneath a crankshaft is formed by joining an upper housing (29) and a lower housing (30) via mating faces (P), and the height of the mating faces (P) is lower on a vehicle front side than on a vehicle rear side. Oil discharge holes (45a, 46) for discharging oil that is within the balancer housing (17) are formed in the mating faces (P) on the higher side of the balancer housing (17) and in the upper housing (29) above the mating faces (P) on the lower side of the balancer housing (17). This enables the position of the oil discharge hole (45a) on the lower side to be as high as possible, thereby suppressing penetration of oil into the interior of the balancer housing (17) through the oil discharge hole (45a).

  • Patent number: 6443136
    Abstract: An internal combustion engine with a breather apparatus, has: a cylinder head cover having a top wall and a circumferential wall which define an internal upper space within the cylinder head cover; and a bottom plate closing an opening at a lower end of the circumferential wall of the cylinder head cover to form a gas-liquid separation chamber. The bottom plate is inclined when the engine is set in a normal posture. A recessed portion for holding oil and serving as an oil return port is formed in a lowest portion along an edge portion of a lower side of a circumferential edge portion of the inclined bottom plate in such a manner as to straddle the circumferential wall from below. Thus, a lower end portion of the circumferential wall is brought into contact with oil held in the recessed portion to thereby close the oil return port airtightly.
