Patent number: 4143624Abstract: A spark-ignited reciprocating-piston internal combustion engine is provided with a combustion chamber subdivided in the top dead center zone into two chambers. These two chambers are separated from one another by overlapping parts of the piston and cylinder and cylinder head when in the top dead center zone, such that when in this position a cross-connection between the chambers exist only at one position along the circumference of the piston. An ignition source is provided adjacent one circumferential end of a first of the chambers which forms a combustion duct between the ignition source and the cross connection. The ignition is controlled so as to take place only after the piston and cylinder are in respective positions separating the combustion chamber into the two chambers.Type: GrantFiled: December 17, 1976Date of Patent: March 13, 1979Assignee: Daimler-Benz AktiengesellschaftInventor: Karl-Walter Schmidt

Patent number: 4142488Abstract: Apparatus for preventing overspeeding of an engine is provided. In preferred embodiments, an hydraulically actuable clutch is controlled by a piston-cylinder arrangement connected to a driver operable clutch pedal. The rear side of the piston in this arrangement is selectively communicated with a high pressure air source and an exhaust space by means of a solenoid valve. The solenoid valve is controlled by a tachometer switch so that the same communicates the high pressure medium to automatically actuate the disengagement of the clutch whenever a predetermined set engine speed is exceeded. The pressure medium space at the side of the piston is also communicated with a further piston-cylinder arrangement for automatically forcing an engine accelerator pedal toward a no-load engine running condition at the same time the clutch is automatically disengaged. An emergency switch is provided for overriding the clutch disengaging apparatus so as to accommodate intentional usage of the engine as a brake.Type: GrantFiled: November 16, 1976Date of Patent: March 6, 1979Assignee: Daimler-Benz AktiengesellschaftInventors: Rudolf Steinecke, Otto Gobke, Klaus Gern
