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 prevent partial wearing in the journal at a crank end and reduce friction losses and the discharge of an oil pump. SOLUTION: In a crank shaft supporting structure, at least one of the journals at both ends of a crank shaft 3 is supported by roller bearings 15 and the other journals are supported by sliding bearings 17. Concretely, a first journal 1J is provided with the roller bearings 15 and the other journals 2J to 5J are provided with the sliding bearings 17. The fifth journal 5J may also be provided with another roller bearing 15 at the opposite end. The loading direction of a crank end is biased due to a timing belt load, an auxiliary belt load and a flywheel weight. Even under such conditions, partial wearing is prevented by the roller bearings 15. The roller bearings 15 reduce friction losses in a lower rotation area in normal use. In addition, since oil supply is unnecessary or let off a little amount, the discharge of the oil pump can be reduced.

摘要： PURPOSE: To reduce the sliding friction loss of a crank shaft with a number of V type or opposed-type cylinders on both its sides and reduce its size by improving the length between the cylinders of each side and the axial position of the crank shaft.
CONSTITUTION: When applied to a 4-cylinder V type engine, the length in the axial direction of a crank shaft 1 between both central lines of the cylinders 51 and 53 on one side of the crank shaft 1 and the cylinders 52 and 54 on the other side is specified below half the inner diameter (d) of the respective cylinders 51W54. Each pair of crank pins 21W24 which corresponds to the cylinders 51W54 on each side is formed on the crank shaft 1 and journals 41W43 are formed only on both sides of each pair of crank pins 21W24. Besides, the axis of the crank shaft 1 is located at the position where a piston 6 is offset toward the side force R which pushes the piston 6 on the inner surface of the cylinder for the length (a) of 10% or more to less than 45% of the piston stroke S during the expanded stroke time of each cylinders 51W54.

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.

摘要： PROBLEM TO BE SOLVED: To provide a piston cooling device capable of improving cooling efficiency.
SOLUTION: Oil S supplied in an annular cooling passage 4 by injection to an oil supply port is discharged from an oil discharging port 6 through the cooling passage 4 so as to cool a piston 2. Oil once discharged from the inside of the cooling passage 4 flows backward in the cooling passage 4 from the oil discharging port 6 with a descent of the piston 2 or the like and along a ceiling surface 4a to spread in the cooling passage 4. By shutting off the oil R with upright surfaces 9a, 10a of shut-off wall members 9, 10, hence, backflow of the oil R in the cooling passage 4 can be prevented.
