    Abstract: A cast piston which includes a metal insert and a combustion bowl, with the metal insert defining a sharp undercut structure at an upper portion of the combustion bowl. The sharp undercut structure of the insert contains combustible gases and helps improve emissions. The metal insert also strengthens the head of the piston. The cast piston is fabricated by positioning the metal insert in a casting mold and casting a piston in the mold. The final shape of the combustion bowl is produced by a machining process which forms the sharp undercut structure on the insert.

    Abstract: A diesel engine (10) has a pre-combustion chamber (30) with an angled and tapered transfer passage (60) leading to the main combustion chamber (44). The transfer passage (60) is tapered to provide a larger lower end (62) facing the main chamber (44) and smaller upper end (64) facing the pre-combustion chamber (30). Air passing through the passage (60) during the compression stroke undergoes heating and swirling within the pre-combustion chamber. The piston has an upper surface (46) with recessed lobes (20) and (22) and recessed passage area (28). Each recessed lobe functions as a valve pocket for the respective intake valve (32) and exhaust valve (42). The valve pockets are deep enough to provide sufficient valve lifts to allow valve overlap periods comparable with spark ignition gasoline engines without interfering with the piston upper surface (46).

    Abstract: A pump has in a housing a revolvable shaft which drives a piston stroke guide body. Drive pistons are provided with piston shoes which run on the guide face of the piston stroke guide body and drive fluid supply pistons of smaller diameter. The pump preferies a fluid separator between lubricating and non-lubricating fluid, like for example, between oil and water, whereof one of the fluids flows through an inner chamber which is provided with inlet and outlet valves while the outer fluid acts in an outer chamber which is open toward the cylinder wherein the fluid supply piston reciprocates. Dead space fillers are provided to prevent losses by compression of fluid and seal means are assembled to prevent leakage of fluid from one into the other of the chambers. The fluid separator may be compressible and expandable within the plastic deformable range of the material whereof it is made. The pump includes sophisticated technologies which necessiated more than half a decade of intensive research and testing but it is now capable of pumping fluid, including water, of several thousand atmospheres of pressure.
