摘要： Otto internal-combustion engines having one injector respectively per cylinder for the internal mixture formation can be operated at full load or high partial load by fuel injection in the suction stroke of the piston and, at medium or low partial load, with a compression stroke injection. The compression stroke injection, which is advantageous in this load range, because of low average combustion space temperatures and the tendency to form deposits in the combustion space because of residues of liquid fuel and the resulting impaired operating conditions, can partially be carried out only to a limited degree. In order to provide a process for operating an Otto internal-combustion engine of the above-mentioned type which permits an arbitrary operating period in the medium or low load range, it is provided that, in the operation of the internal-combustion engine with a compression stroke injection, as a function of the time or at least of an operating parameter, independently of the momentary load requirement, a change-over takes place to a suction stroke injection while simultaneously reducing the intake air quantity and, after the conclusion of a certain free-burning interval, a switching-back takes place into the operating mode with the compression stroke injection.

摘要： In an internal combustion engine and a method of operating the engine which comprises a compressor having an impeller disposed in a housing including a main inlet duct in which the impeller is supported and an additional inlet duct joining the main inlet duct in the area of the compressor impeller, and valving means for controlling the gas supply to the inlet ducts and an electric motor connected to the compressor impeller for rotation therewith so that the compressor is operable by the electric motor and by the pressure drop in the air intake line of the engine, a flywheel is coupled to the impeller for storing rotational energy when the impeller is driven by the intake gas and returning the energy to the impeller when the pressure drop collapses upon a sudden increase in the demand for engine power.

摘要： Switching off a fuel pump of a fuel supply system for the internal combustion engine with the aid of a signal from a retardation sensor of the airbag in the event of a crash in which the motor vehicle is involved is known. To further enhance the safety of motor-vehicle occupants, a method is proposed for an internal combustion engine which has at least one fuel injection valve, a fuel supply system for the at least one fuel injection valve, and a sensor for detecting a crash. After the crash has been detected by means of the sensor, the fuel injection valve is brought into an open position, with the result that fuel is discharged from the fuel supply system of the fuel injection valve into a combustion chamber of the internal combustion engine. The method according to the invention is provided for internal combustion engines with at least one fuel injection valve.
