摘要： The invention relates to a four-stroke internal combustion engine with spark ignition and direct injection of the fuel into the combustion chamber, with a reciprocating piston for each cylinder and a roof-shaped top of the combustion chamber with at least one exhaust valve and at least two intake valves, as well as intake ports generating a tumble flow in the combustion chamber, as well as a fuel injection device opening into the combustion chamber, and an ignition source located in the area of the cylinder axis in the roof of the combustion chamber. In order to obtain good internal flow conditions the surface of the piston facing the combustion chamber is provided with a substantially Y-shaped configuration of flow guiding ribs, of which an arc-shaped rib is positioned approximately in the center of the piston and encloses a trough-shaped recess, and a longitudinal rib is provided on the side of the arc-shaped rib opposite of the recess, and the ignition source is positioned above the recess, and the fuel injection device is positioned in the area of the cylinder wall between the intake valves.

摘要： In a method for the analysis and evaluation of measured values of an open test system, a test piece is monitored during a test run by at least one signal channel which sends a signal to an evaluation unit for further processing whereby at least one plausibility node is coupled with at least one signal channel. In order to allow a statement to be made about the value of plausibility nodes and their results in relation to a specific measuring task, an evaluated plausibility is ascertained for at least one of the measured values from the type and number of plausibility nodes as well as their possible, variable interconnection.In order to permit, in addition, statements on the reliability of the results of the test system in relation to the desired measured values, it is provided that from the type and number of available plausibility nodes in combination with the type and number of available signal channels, a value is ascertained for the confidence level of the plausibility of at least one of the measured values of the current test system.

摘要： An exhaust gas muffler comprises a double-walled casing having an inlet end receiving a stream of the exhaust gas and an outlet end for the exhaust gas, the outlet end comprising an outer tube surrounding a perforated inner tube spaced therefrom, and the tubes defining therebetween a perforation resonator chamber succeeded by a whistling sound resonator. The casing includes an outer wall and a corrugated inner wall defining a gap with the outer wall. A heat-resistant and sound-damping intermediate layer is arranged in the gap between the inner and outer walls and braces the inner wall against the outer wall. Transverse partitions divide the casing into a plurality of chambers between the inlet and outlet ends, and tubes connect the chambers and reverse the exhaust gas stream at least twice between the inlet and outlet ends.

摘要： An intake muffler, which is particularly intended for use in two-stroke-cycle internal combustion engines, comprises a stiff housing, in which a partition defines two chambers. An inlet tube extends into the larger first chambr. At least two communicating tubes extend through the partiton. The second chamber communicates with a tubular outlet port. In order to ensure an effective damping of sound even in conjunction with a high engine power, the inlet tube consists of a diffuser, which is divided into two or more passages, and the tubes through which the two chambers communicate with each other differ in diameter and/or in length.
