摘要:
An internal combustion engine has a cylinder with a combustion chamber delimited by a reciprocating piston that drives a crankshaft rotatably supported in a crankcase. The internal combustion engine has an intake passage, an exhaust connected to the combustion chamber, a device supplying fuel, and a control device controlling at least one operating parameter of the internal combustion engine. The internal combustion engine is operated in that a pressure is measured in operation of the internal combustion engine, an adjustable value for at least one operating parameter of the internal combustion engine is deteremined based on the measured pressure, and the determined adjustable value is set for optimized running of the engine.

For determining the respective geometrical position, the displacement or angle of a body by capacitive sensing, a supply voltage applied to a voltage-distribution element is switched, and/or phase-shifted voltages are applied, in such a way that at least two different distribution patterns of the supply voltage, that follow each other in time, are obtained across the voltage divider.
摘要:
A road finishing machine comprising a diesel-hydraulically driven set of main wheels and at least one set of steerable wheels. An additional hydraulic companent is provided which transfers a driving force to the steerable wheels, and the peripheral speed of the steerable wheels is automatically adapted to that of the main wheels.

摘要:
A road surface finisher with a tire drive and a chassis that carries a material bin in the front and, in the rear, a transverse spreading device with an installation beam. A primary drive unit which includes an internal combustion engine and at least one main pump, which drives hydraulic secondary drives of steerable front wheels and of rear wheels, is also mounted on the chassis. The front wheels are driven by hydraulic front wheel motors, and the rear wheels, respectively, are driven by a master drive that includes a hydraulic transport motor and a hydraulic working motor. The hydraulic master drive of the rear wheels and the hydraulic front wheel motors are fed by a single shared drive pump, which is driven by the primary drive unit.
