    • An air-compressing reciprocating piston-equipped internal combustion engine comprises, in a piston head of the piston, a cavity being axially symmetrical about a central cavity axis and constituting a combustion chamber, as well as a fuel injection nozzle for injecting fuel directly into the said cavity. The nozzle has a longitudinal nozzle axis which encloses with the central cavity axis an acute angle. In order to generate a rotary motion of an air charge fed into the said cavity, there is provided a correspondingly designed air-feeding unit. A uniform distribution of the fuel in the cavity serving as combustion chamber is achieved by subdividing the cavity into imaginary compartments with the aid of dividing planes extending parallel with the central cavity axis, and each dividing plane through a different one of the axes through at least three orifices of the nozzle, in such a manner that the ratio of the fuel quantity ejected by a given nozzle orifice, in a specific injection phase, to the total amount of fuel ejected by all orifices of the nozzle during the same phase is about equal to the ratio of the volume of the respective imaginary compartment, following in the direction of air charge rotation after the said given nozzle, to the entire volume of the air charge in the piston cavity serving as the combustion chamber.

    • In a method for braking a four-stroke internal combustion engine having cylinders each having a combustion chamber and at least one outlet valve connected to an outlet system and controlled by an engine camshaft, wherein the outlet system comprises a choke device, the flow of exhaust gas in the outlet system is choked with the choke device such that the exhaust gas upstream of the choke device is subjected to a pressure increase.

    • A device for increasing the braking power of a multi-cylinder internal combustion engine of a vehicle during engine braking operation including a turbosupercharger and an exhaust gas turbine for each stage thereof. A respective bypass line branches off from a region of two exhaust gas header pipes that can be blocked by throttle valves. Each bypass line communicates with a nozzle bore in a turbine wall. The nozzle bores are in a plane perpendicular to a turbine wheel axis and extend either parallel next to one another or at an acute angle to and merging with one another. The nozzle bores open out into the turbine chamber directed tangentially onto the outer portion of the turbine wheel. During an engine braking operation, two partial exhaust gas streams are branched off by the bypass lines from exhaust gas retained in blocked header pipes and strike turbine wheel blades at high pressure and high speed, whereupon the turbosupercharger is driven in an accelerated manner and compressed air is supplied to combustion chambers of the engine and is there effective to increase braking power.

    • A method for engine braking of a multi-cylinder internal combustion engine of a vehicle, which is preferably an engine operating on the diesel principle. The engine has at least one exhaust-gas turbocharger with an exhaust-gas turbine and a charge air compressor, and an exhaust manifold which supplies the exhaust-gas flow from outlet valves of the engine to the exhaust-gas turbocharger.

Here, the engine has at least one exhaust-gas turbocharger having an exhaust-gas turbine acted on by an exhaust-gas flow and having a charge air compressor, which exhaust-gas turbine and charge air compressor are arranged on a common shaft. The engine also has an exhaust manifold which conducts the exhaust-gas flow from outlet valves of the engine to the exhaust-gas turbocharger, and has a device for throttling the exhaust-gas flow arranged between the outlet valves and the exhaust-gas turbocharger, and also has at least one bypass line for conducting the exhaust-gas flow past the throttling device, the exhaust-gas flow being conducted through the at least one bypass line to a turbine wheel of the exhaust-gas turbine, the exhaust-gas flow being throttled and a pressure increase in the exhaust gas thus being generated upstream of the device for throttling the exhaust-gas flow. According to the method, a measurement of an exhaust-gas counter-pressure and of a charge air pressure preferably take place. On the basis of the measurement of the exhaust-gas counter-pressure and of the charge air pressure, a determination of an optimum position of the device for throttling the exhaust-gas flow to obtain a predetermined braking action can be carried out. The exhaust-gas counter-pressure and of the charge air pressure are subsequently controlled by adjusting the device for throttling the exhaust-gas flow corresponding to the determination of the optimum position of the throttling device.
