Abstract: PROBLEM TO BE SOLVED: To stably carry an oil between a crank shaft and a main bearing to improve lubrication performance and startability.SOLUTION: A journal 20 of the crank shaft 18 is rotatably supported by the main bearing 22. The oil is supplied to a sliding surface between the journal 20 and the main bearing 22 through a lubricating oil passage 30 and an oil hole 40, and the oil is kept by an oil carrying mechanism 42. The oil carrying mechanism 42 includes an annular protrusion 44 provided on an inner peripheral surface of the main bearing 22 on both axial sides of the oil hole 40 and an annular recess 46 provided on an outer peripheral surface of the journal 20. Thus, the oil can be prevented from flowing out from the sliding surface while an engine 10 stops. Therefore, high lubrication performance can be secured from the beginning of the start when restarting the engine, and the startability can be improved by inhibiting friction.

Abstract: PROBLEM TO BE SOLVED: To promptly respond to an abnormality even when the abnormality occurs in a variable valve train in a condition, such as low rotation and low speed, which makes the operation of a hydraulic system difficult. SOLUTION: An internal combustion engine 10 has the variable valve train 68, a lash adjuster 80 and an adjuster movable mechanism 82. In the state where the variable valve train 68 is normal, the lash adjuster 80 is held in the normal position by the adjuster movable mechanism 82. When an abnormality of the variable valve train 68 is detected, the lash adjuster 80 is held in the retract position by the adjuster movable mechanism 82 to reduce projection dimension T of a plunger 80B compared to the normal state. Thus, when an abnormality is detected, lift amount of an intake valve 38 can be reduced regardless of engine speed and temperature state of the internal combustion engine 10. As a result, an interference between the intake valve 38 and a piston 16 can be securely prevented. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a novel structure for suppressing flow resistance of cooling water while utilizing latent heat cooling for improving the efficiency of cooling a cylinder head.
SOLUTION: A latent heat cooling chamber 20 is formed to cover the outside (the upper face) of a heat source portion of a combustion chamber 4 or the like, and a cooling water channel 41 is formed for the latent heat cooling chamber 20 across a partition wall 43. The cooling water flows along the upper face of the partition wall 43 not along the outer face of the heat source portion. The shape of the partition wall 43 is independent of the complicated shape of the heat source portion. The existence of the latent heat cooling chamber 20 permits good cooling operation near the heat source portion, while proper shape design of the partition wall 43 suppresses flow resistance.
