A sliding surface of at least one of sliding members sliding with respect to each other in a sliding direction comprises a protrusion extending along a direction intersecting the sliding direction and fine dimples provided on a surface of the protrusion. In the sliding members, lubricating oil is accumulated in the dimples, and is easily extracted through a drain portion formed by dimple in a running-in operation.

Sliding members and piston for internal combustion engine

In an engine block structure in a multi-cylinder engine in which a piston is incorporated from the side of a crank chamber into each of a plurality of cylinders disposed in series in a cylinder block, cylinder axes of the two adjacent cylinders are disposed to extend in such directions that they are gradually spaced apart from each other as proceeding from the side of a valve operating chamber toward the crank chamber as viewed from a direction of arrangement of the cylinders. Thus, a sufficient crankshaft bearing area can be ensured without bringing an increase in number of parts and an increase in size of the engine block.

Engine block structure in multi-cylinder engine

A housing of a motor generator is integrally coupled to an end of an internal combustion engine. The internal combustion engine includes an oil pan and a cylinder block which have arcuate stiffener ribs and radial stiffener ribs on end surfaces thereof for increased mechanical strength of the internal combustion engine. The motor generator has a housing that is directly coupled to the internal combustion engine with a relatively small number of parts.

Hybrid vehicle propulsion apparatus

In an engine for a vehicle including a bearing cap integral type oil pan which has a plurality of bearing cap sections integrally provided thereon and which is integrally coupled to a cylinder block, connecting bolts are screwed into the bearing cap sections from the cylinder block to integrally couple the cylinder block and the oil pan to each other. An oil pan chamber, which is an as-cast bore made by drawing a die in an axial direction of a crankshaft, is defined to extend continuously in the axial direction of the crankshaft between the bearing cap sections and a bottom wall of the oil pan. Thus, the oil pan can be produced simply, at a low cost, by a casting process and moreover, it is possible to reduce the weight and size of the oil pan and increase the rigidity of the oil pan.
