Title: Fuel injection pump for IC engine - has sleeve fitted to piston to vary quantity of fuel delivered
Inventor: SCHWARZ VOLKER DIPL ING
IPC: F02M59/26
Filed: 1990-05-22
Abstract: The fuel injection pump is for an IC engine and has a cylinder (2) in which a piston (3) operates. The fuel flows into the cylinder bore (2) through a central longitudinal hole (10) and a radial hole (11). The timing of fuel delivery and cut-off is controlled by the edges of grooves (15) in the piston (3) and by the edges of grooves in the bore of a sleeve (6) which can slide on the piston (3). The interval between the beginning of fuel delivery and fuel cut-off can be varied by varing the position of the sleeve (6) relative to the piston (3). USE - Fuel injection pumps for IC engines.

Title: Rotary piston IC engine - has at least one twin piston system with two pistons rotating symmetrically round common axis
Inventor: OSTERBURG GUENTER
IPC: F01C11/00
Filed: 1990-06-01
Abstract: Two interlocking rotary piston systems (A, B) in a common housing (2) have parallel axes and rotate in opposite directions. The piston working surfaces are circular and have an area of overlap. They are linked via ducts (42, 50) to a separate combustion chamber (52) with the flow to and from the ducts (42, 50) being controlled by the pistons acting as shutoff valves. - Radially the outer circumferential area of each rotary piston takes the shape of the joint faces of a circular cylinder, which during rotation alternately form very deep sealing apertures with the housing and the other piston system. The frontal areas interact with the frontal areas of the other piston system as the two systems alternately interlock.
