Abstract:
A connecting rod is provided, which includes a rod shaft and a rod cap. The rod shaft and the rod cap can be releasably fastened through connecting means to form a connected state, and when the rod shaft and the rod cap are in the connected state, they form a rod eye configured to enclose a bore for mounting the connecting rod on a crank shaft. The rod shaft and the rod cap have contact surfaces at which they touch each other in the connected state. The contact surfaces have an interlocking section-wise serration, and the contact surfaces have an un-serrated section.
Abstract:
A control device for the selective control of a multiplicity of actuators of an internal combustion engine, comprising: - a central control unit (1); - a multiplicity of actuators associated with the multiplicity of actuator controls (2), which are connected to the central control unit (1), wherein each actuator control (2) of the multiplicity of actuator controls (2) comprises an address, so that the actuator controls (2) are selectively controllable by the central control unit (1) by means of the address and that each actuator control (2) comprises a comparator (6), which is configured to compare a signal, preferably a voltage or current signal, emitted by the central control unit (1) with the address and to emit an activation signal via an activation line (13), if the comparison has resulted in a match of the signal with the address of the respective actuator control (2) within a window, preferably voltage window (ΔV).

Abstract:
A method for detecting the quantity of gas (m) which is supplied by means of a gas supply device (4) to an antechamber (3) of an internal combustion engine (1), whereby a targeted disturbance (Au) of the gas quantity (m) supplied by the gas supply device (4) is performed and a change (AT) resulting from the target disturbance (Au) in an exhaust gas temperature (T) of an exhaust gas generated in a combustion chamber (2) connected to the antechamber (3) is measured, whereby, by comparison with a target value of the change (ATtarget) of the exhaust gas temperature (T), the gas quantity (m) supplied by means of the gas supply device (4) is deduced.
Abstract:
A combustion engine with at least one injector for the injection of liquid fuel into at least one combustion chamber, which injector can be regulated by means of a regulating device through an actuator triggering signal, wherein the at least one injector has an outlet opening that can be closed by means of a needle (6), wherein an algorithm is contained in the regulating device, which receives, as an input value, at least the actuator trigger signal (Δt), and which calculates via an injector model the mass of liquid fuel transferred via the outlet opening of the injector, and which compares by means of the injector model the calculated mass with a required target value ref (m d ref ) of the mass of liquid fuel, to correct the actuator trigger signal (Δt).
