摘要： PROBLEM TO BE SOLVED: To provide a bearing structure for an engine, suppressing the generation of unusual sounds.
SOLUTION: A clamp journal 12 of a crank shaft 3 is rotatably supported by a crank shaft bearing 14 formed of a cylindrical metal. An oil film layer is formed in a gap 22 between the outer periphery face of the crank journal 12 and the inner periphery face of the crank shaft bearing 14 by lubricating oil supplied through an oil passage 17. Grooves 20, 21 are formed in the ends of both the outer periphery face of the crank journal 12 and the inner periphery face of the crank shaft bearing 14 in their axial directions, respectively. The grooves 20, 21 are formed all over the peripheries with their widths being 0.5mm and their depths being 0.5mm (their cross sections being 0.25mm

摘要： PROBLEM TO BE SOLVED: To further restrain variation of a resonance frequency of a combustion chamber in an ignition region than conventional.SOLUTION: An ignition device 10 of an internal combustion engine comprises: a combustion chamber 12 provided in a cylinder 20 and burning air-fuel mixture; a piston 14 arranged in the cylinder 20 and moved in the cylinder 20 by combustion; and electric field generation means 16 provided on a ceiling face 24 of the combustion chamber 12 opposed to a top face 22 of the piston 14 faced to the combustion chamber 12, and burning the air-fuel mixture by generating an electric field in the combustion chamber 12. Furthermore, the ceiling face 24 has a plane shape that is not flush, and the top face 22 is formed so that a separation distance between the top face 22 of the piston 14 and the ceiling face 24 in a moving direction of the piston 14 is almost constant on the entire face.

摘要： PURPOSE: To effectively produce turbulence for improving combustion efficiency by forming a main recess and a sub-recess communicating to each other through at least two projections on the upper portion of a piston to flow swirling intake air into a combustion chamber.
CONSTITUTION: On the upper portion 20 of a piston 1 are formed a main recess 21 having the round cross-section and sub-recesses 23 communicating to the main recess 21 through three arcuate projections 22 and consisting of three arcs having curvature larger than that of the projection 22. Also, an intake path IP is formed with a helical intake port as a swirling mechanism for giving swirling flow to intake air supplied to the main recess 21 in a combustion chamber. An ignition section of an ignition plug as an ignition system is provided adjacently to the outside of the outer periphery of the main recess 21. The swirling flow accelerated and introduced into said recess 21 is made turbulence by the projections 22 and secondary swirling flow is produced in the sub-recesses 23 so that further turbulence is produced between these swirling flows.
