Publication number: 20030005894Abstract: A radial piston engine is disclosed wherein power is transferred such that the power take-off is truly balanced, where the piston runs truly parallel to the cylinder walls. This concept reduces wear of the cylinders and piston rings. The engine provides improved gas mileage due to the reduced piston drag. One unique feature is the power take-off from the piston to the flywheels. The design takes power from inside the cylinder compartment, through four transfer arms, to cams that in turn transfer the power to two flywheels. By firing complimentary cylinders 180 degrees at the same time, almost no vibration is noticed. Also, since the cylinders can fire many times per flywheel rotation, the torque which this engine produces is greater other designs. Any number of cylinders is possible. Single cylinders and two cylinder designs with chain power take-offs are also possible for lawnmowers and motorcycles.Type: ApplicationFiled: July 5, 2002Publication date: January 9, 2003Inventor: Thomas J.

Publication number: 20030005898Abstract: In a Diesel engine with variably actuated valves, the cam controlling each inlet valve is shaped to provoke the opening of the respective inlet valve during the engine's normal exhaust phase and thus realize exhaust gas recirculation within the engine, due to the fact that during the normal exhaust phase, part of the exhaust gas passes from the cylinder into the inlet port, from where it returns to the cylinder during the next induction phase, while part of the exhaust gas that had previously passed into the exhaust port returns to the cylinder during the said induction phase due to the additional opening of the exhaust valve, in consequence of which the exhaust gas charges that return to the cylinder are subjected to further combustion in the next engine cycle.Type: ApplicationFiled: June 28, 2002Publication date: January 9, 2003Applicant: C.R.F.

Publication number: 20030005899Abstract: A system for the rotation of a camshaft relative to a crankshaft of an internal combustion engine, which includes a drive pulley connected to the crankshaft of the engine through a chain, belt, or sprocket drive, and includes an electric motor that transfers torque to the camshaft of the engine. The electric motor is flanged directly to one end of the and is a primary drive unit of the camshaft as well as a servomechanism to adjust and maintain a controlled camshaft angular shift, whereas the drive pulley is fastened to and moves about the other end of the camshaft within a defined range of rotation and is provided as a forced synchronization instrument for the electric motor within the range of rotation, as well as being a secondary drive unit of the camshaft. Further, the electric motor (7) is connected to an RPM controller (10) that synchronizes and modifies the RPM of the electric motor (7) relative to the RPM of the drive pulley (4).Type: ApplicationFiled: April 4, 2002Publication date: January 9, 2003Applicant: INA-Schaeffler KGInventor: Martin Scheidt

Publication number: 20030005900Abstract: An electronically controlled engine management system for adjusting camshaft timing, taking into account mechanical deficiencies of a variable camshaft timing mechanism and compensating the mechanical deficiencies by manipulating the amount and/or timing of the fuel injection. The engine management system enables the operator to enjoy high torque and good fuel efficiency representative of the compensated adjustable camshaft timing system.Type: ApplicationFiled: June 24, 2002Publication date: January 9, 2003Inventors: Goichi Katayama, Yoshibumi Iwata

Publication number: 20030005901Abstract: A marine drive has an engine, a propeller and a transmission to switch the propeller between a propulsion position and a non-propulsion position. The engine has a combustion chamber. An air induction system communicates with the combustion chamber through an intake port. An exhaust system communicates with the combustion chamber through an exhaust port. Intake and exhaust valves move between an open position and a closed position of the intake port and the exhaust port, respectively. Intake and exhaust camshafts actuate the intake and exhaust valves, respectively. A VVT mechanism changes an actuating timing of the intake camshaft at which the camshaft actuates the intake valve. An ECU controls the intake camshaft to set the actuating timing at a generally optimum timing. A transmission position change operation sensor senses that the transmission is under operation and sends a signal to the ECU. The ECU controls the VVT mechanism based upon the signal to move the actuating timing away from the optimum timing.Type: ApplicationFiled: July 3, 2002Publication date: January 9, 2003Inventor: Goichi Katayama

Publication number: 20030005903Abstract: The invention relates to a holder for the attachment of units, preferably of fuel-pressure injection pumps to cylinder heads of reciprocating internal combustion engines. In this case, the holder replaces one or more camshaft bearing caps and thus permits a high-pressure fuel injection pump to be installed and operated in a simple manner.Type: ApplicationFiled: June 20, 2002Publication date: January 9, 2003Applicant: Ford Global Technologies, Inc.Inventors: Detlev Kunde, Guido Bingen, Gunnar Gangel, Hans-Joachim Reincke

Publication number: 20030005904Abstract: The invention relates to a device of the build-up of pressure in supply systems (6, 11, 20, and 23) to components (19, 36) on internal combustion engines (2). The invention includes directly couples lubricant systems and pressure-generating systems (3, 8), an electric fuel pump (34), as well as a control apparatus for determining lubricant pressures. A supply module (12, 34) is provided with an independent drive (16) and supplies lubricant in the lubricant oil circuit (24) or to selected lubricating position, or fuel into a fuel supply (36). The supply module (12, 34) can optionally include a pressure converter (30).Type: ApplicationFiled: May 15, 2002Publication date: January 9, 2003Inventors: Hermann Gaessler, Udo Diehl, Karsten Mischker, Rainer Walter, Bernd Rosenau, Juergen Schiemann, Christian Grosse, Georg Mallebrein, Volker Beuche, Stefan Reimer
