Abstract: An improved lubrication system for a two-stroke engine having a lubrication path from an oil sump directly to an induction valve assembly for noise reduction. The oil sump is divided into two chambers with a restricted passage therebetween to ensure lubrication of transmission gears upon startup while reducing drag during operation. A cross-drilled lubrication passage through each crankshaft throw terminates in a second passage proximate a dead-end plug, the second passage being in communication with the piston rod bearing. Each piston skirt includes at least one axial groove in registration with an oil supply passage. Circumferential grooves distribute the oil around the piston skirt from the axial grooves. The pistons may include ceramic top layers for heat insulation to increase the compression ratio possible by raising the ring positions. The engine incorporates an air/oil mixture separator within a balancer shaft chamber and air from the chamber is directed to the intake system.

Abstract: A piston for diesel engines is made of a toughness-increasing aluminium alloy containing copper, nickel, silicon, magnesium, iron and manganese. The use of this material, which can conventionally be chill-cast, and by implying special dimensions, provides a piston which, despite its relatively light construction, provides the utmost security against cracking in the stressed regions, e.g. the piston boss or the combustion chamber recess.

Abstract: A method of flexibly manufacturing engine blocks by first bonding an extruded tube liner insert, of a given thickness (1-15 mm), to a fixed configuration block, the liner insert having been coated with an anti-friction wear-resistant coating having a controlled standard thickness, and secondly bonding an extruded tube liner insert of a different thickness (again selected from 1-15 mm) to another of the fixed configuration blocks, the second liner insert having been coated with the same type of anti-friction wear-resistant coating in essentially the same controlled standard thickness. The common sized engine block can have (i) identically shaped circular cylindrical bore walls or (ii) ovoid cylindrical bore walls with the liner insert having an interior surface shape selection varying between circular to ovoid. The block and liner insert may be both made of aluminum. To promote wear-resistant and lubricant qualities, the coating may contain a mixture of hard particles (such as stainless steel, nickel, chromium or vanadium) and solid lubricant particles such as oxides of iron having controlled oxygen, BN, LiF, NaF.sub.2 or a eutectic of LiF/NaF.sub.2.

Abstract: A piston for developing compression within the cylinder of a combustion engine or other type compression generating apparatus; said piston being a two-piece assembly, whereas the topside portion, or traditionally known as the crown, being of relative disc-shape in relation to asymetrics of said piston, is connected to the lower portion, or traditionally known as the skirt, by a distinct fastening means that consist of said crown being concaved from the underside and having multiple vertically positioned ridges that align the inside perimeter of said underside. Said skirt has another set of matching vertically positioned ridges that align the outer perimeter at the top of said skirt, as said top is appropriately sized to match said underside of said crown so that said crown may be press-fitted to said top of said skirt for a rigid and complete piston assembly. Said two-piece assembly allows said piston to be comprehensively configured of two distinctively different material compositions, such as, said crown being composed of a latent-cast elemental metal and said skirt being composed of a resin-based epoxy.
