In a connecting rod of a piston machine which comprises two separate parts which are longitudinally movable relative to one another but operatively interconnected and of which one part is connected to the piston and the other is rotatably mounted on the crank of a crankshaft, the two connecting rod parts are interconnected by a fluid spring structure in which a fluid is utilized as a spring element for operatively interconnecting the connecting rod parts.

A method for the regulation of the mixture composition in a mixture-compressing internal combustion engine with an electronically controlled fuel injection system. In order to be able to dispense with a lambda probe, the mixture is initially enriched or leaned for each cylinder unit directly after the start of the internal combustion engine, the change between two successive firings of the energy pulse introduced into the crankshaft by an ignition is continuously determined thereafter and the mixture is enriched in the case that the amount of the respectively determined energy pulse change lies above a predetermined shifting-comparison value dependent on operating parameters, and otherwise is leaned down.

A process and equipment for removing toxic and malodorous gases from the fresh air for vehicle cabins by catalytic oxidation, the process being based on passing the fresh air over a heating-system heat exchanger, the heat-emitting surfaces of which form the support for an oxidation catalyst. The heat exchanger used is the heating-system heat exchanger which is present in virtually all motor vehicles. In contrast to known solutions for purifying the fresh air, for example by means of activated carbon, the process is maintenance-free and does not require any additional constructional volume.

Use of a metallic partial composite laminate body which is provided with a large number of axially extending channels and is made by expanding a large number of layers, as support for exhaust gas catalysts of Otto-engines in which the mutually oppositely disposed non-inflated edge portions of the expanded partial composite laminate body serve for a particularly stable fastening of the support in the catalyst housing.

A fuel injection system for a mixture-compressing spark ignition internal-combustion engine has a fuel-metering device having a housing with a control cylinder arranged therein, a control piston having at least two control edges being rotatably and longitudinally slidably arranged in said control cylinder. One front surface of said control piston is acted upon by fuel and its other front surface interacts with a pressure spring. Between the control edges, the control piston is equipped with a control space area. The housing has an inflow opening for a fuel inflow pipe, an outflow opening for a fuel return flow pipe in which a pressure regulating valve is arranged, and an outflow opening assigned to a fuel injection nozzle. The outflow opening connected with a control opening in the control cylinder interacts with the control edges. The control space area has at least one recess at the control piston having a circular-arc-shaped area segment forming the control edges in order to provide a fuel injection system having a fuel-metering device of the initially mentioned type which is simple to manufacture and easy to assemble, exhibits high operational reliability and ensures an exact metering of fuel. The axis of said area segment extends transversely to the control piston axis and starts from the circumferential area of the control piston in a concavely curved manner extends into the control piston. The control piston has an axial flow-through bore equipped with a throttle downstream from the recess. The fuel passes through said flow-through bore from the inflow opening of the housing to the recess and to the outflow opening of the housing.

A measuring device that is moved corresponding to the amount of medium flowing through a housing is provided for measuring the flow rate of a gaseous or liquid medium through the housing. The displacement of the measuring device represents a measurement of the amount of medium flowing through the housing and during the displacement of which, a movable part of a control valve is adjusted for metering a control medium volume that is proportional to the flow of medium in the housing. The measuring means is pivotably mounted at an upstream end to the housing and, at a downstream end, rests against the wall of the housing in its closed position. In order to provide an arrangement that is simple to manufacture and is not susceptible to momentary disturbances and which records the measured values exactly, the measuring means comprises a concavely shaped leaf spring which interacts with the flow of medium.

Arrangement for measuring the rate of flow of a gaseous or liquid medium

A drive arrangement which includes a number of internal combustion engines which are adapted to be connected to a flow of working force through free wheeling or one way clutches and gears to a common output shaft. In addition to a flow of working force the individual internal combustion engines may be interconnected by another flow of a tractive force which is formed by gearing up gears and one way or free wheeling clutches. This flow of tractive force acts only in a direction of force flow which opposes the flow of the working force. The internal combustion engines may be mechanically arranged in parallel next to one another or in series behind one another with working or output shafts of the internal combustion engines being located parallel or in series one behind the other. The working shafts are connected with parallel gear stages which transmit at different ratios and have opposing force flows. Only one gear stage acts at a time in any direction of force flow due to an alternating arrangement of the one way or free wheeling clutches.
