Abstract: An engine includes a crankcase; an oil sump; at least one balancing shaft mounted in a balancing tunnel of the crankcase, which includes first and second end portions and a central portion extending between the end portions; and a blow-by gas recirculation system having an inlet channel communicating with the oil sump, an outlet channel communicating with an intake manifold, a centrifugal separator arranged between said inlet and outlet channels, and a drainage channel opening into the oil sump for discharging separated liquid. The inlet channel communicates with said first end portion, and said centrifugal separator is housed in said second end portion and is driven in rotation by said balancing shaft. The outlet channel communicates with a gas outlet of said centrifugal separator, whereby, during operation, blow-by gas flows successively through the central portion and the centrifugal separator in a path from the inlet to the outlet channel.

Abstract: A cylinder block assembly for an engine comprises a cylinder block having a sidewall provided with apron attachment points and an apron mountable on the sidewall. The apron is adapted to receive engine components and comprises a tray-like cover which is dimensioned to substantially conform with the side of the cylinder block, thereby avoiding the need to machine the cylinder block to receive engine components. A cylinder block may be customized by the provision of an apron having appropriate components attached to the cylinder block, so that a single cylinder block can be used for a number of different engines.

Abstract: A multi-piston assembly is illustrated wherein a cylindrical housing (A) is ported through longitudinal circumferentially spaced ports (F) and (G) carried within the cylindrical housing. Porting through piston rods is thus avoided so that their cross section may be reduced thereby increasing the area of the pistons available for contact by pressurized fluid. Even greater force may be made available for actuating a tool by the addition of an add-on unit utilizing complementary longitudinal porting.

Abstract: A powertrain including an engine and attached power transmission means has a stiffening bracket extending between the side walls of the engine block and the transmission means housing. The bracket extends under and separate from the engine oil pan and has integral ribs depending from a floor and extending longitudinally and diagonally from the power transmission connections to each of the side wall connections to add both bending and torsional stiffness to the powertrain, thus reducing vibration, noise and stress.
