Abstract: Provided is a valve housing configured to be inserted into an insertion hole that extends in a direction approximately orthogonal to an extending direction of an oil path and configured to be freely movable along an extending direction of the insertion hole. When an oil jet switching valve is closed, the tip end portion of the valve housing is configured to be pressed to the inner wall surface of the oil path by receiving an energized force from an energizing unit.

Abstract: An aluminum cylinder block (1) of an engine has a plurality of cylinder bores (2), and intermediate marginal areas (17) defined between adjacent cylinder bores (2). A single water jacket (8) is formed in the cylinder block (8) to surround the plurality of cylinder bores (2), and a plurality of oil chutes (15) are also formed in the cylinder block (1) outside the water jacket (8) for allowing an oil to drop from a cylinder head (5) to a crankcase (14) therethrough. These oil chutes (15) are formed between adjacent intermediate marginal areas (17) so that they do not make the cylinder block (1) swell out. An air in the oil chutes (15) functions as a sound insulation layer against combustion noises generated in the cylinder bores (2). The air in the oil chutes (15) also serves as a heat insulation layer for a cooling water in the water jacket (8) so that warming up performance of the engine under a cold condition is improved.

Abstract: In an internal-combustion engine, the light-metal cylinder head 1 is bolted together with the cylinder crankcase 2 by means of bolts 9, which extend in each case through a bore hole 10 in the cylinder head 1 and are bolted into a threaded borehole 11 in the cylinder crankcase 2. In order to keep the surface pressure, when the cylinder head bolts are tightened, at a level permissible for the light-metal alloy of the cylinder head 1 without using shims that require much space, a threaded sleeve 15 of steel, on the face 17 of which the head of the cylinder head bolt 9 is lying, is screwed into the borehole 10. The bearing surface for the force of the bolt is formed by the areas of the edges of the thread of the threaded sleeve 15. Accordingly, a sufficient area can be made available by an appropriate number of threads without the need to have the external diameter of the threaded sleeve 15 larger than the external diameter of the bolt head 12, 13.

Abstract: A two-stroke internal combustion engine of the crankcase scavenging type, in which a nozzle connected to a lubricant feed line is provided in the intake passage for picking up oil from a lubricant reservoir via a partial vacuum. For simple and sufficient lubrication and cooling of the crank gear in accordance with the respective requirements of the engine, the nozzle (62) is positioned in the area of the smallest cross-section of a Venturi-tube-like part (60) of the intake passage, and an injection pump (54) is provided for fuel delivery, which eliminates the need for an oil pump.
