Abstract: The invention relates to a system (1) for analyzing an energy efficiency of a motor vehicle (2), having: a first device (4a, 4b), in particular a sensor, configured to detect a first data set of at least one first parameter, which is suitable to characterize energy consumed by at least one apparatus A, in particular a steering system or drive device (3); a second device (5a, 5b, 5c, 5d), in particular a sensor, configured to detect a second data set of at least one second parameter, which is suitable to characterize an operating state of the at least one apparatus A; a third device (6), configured to detect a third data set of at least one third parameter, which is suitable to characterize at least one driving state of the vehicle (2); a first comparison device (7), in particular part of a data processing device, configured to compare the values of the second data set with predefined parameter ranges which correspond to at least one operating state, and to compare the values of the third data set with predefined parameter ranges which correspond to at least one driving state; an allocation device (8), in particular part of the data-processing device, configured to allocate the values of the first data set and the values of the second data set to the respectively present at least one driving state; and a processing device (9), in particular part of the data-processing device, configured to determine at least one first characteristic value which characterizes at least the energy efficiency of the at least one apparatus A on the basis of the first data set and the second data set as a function of the at least one driving state.

Abstract: Various embodiments of the present disclosure are directed to methods of operating a spark-ignition internal combustion engine. In one embodiment, a method is disclosed including fuel is injected centrally into a combustion chamber via at least one fuel injection device per cylinder in at least one operating range of the internal combustion engine and is ignited centrally in the combustion chamber via at least one ignition device. The fuel is injected into the combustion chamber at an injection pressure of over 500 bar in the second half of the compression stroke before the top dead center of combustion and the internal combustion engine is operated at an air-fuel ratio λ≥1.
In at least one operating range of the internal combustion engine, the fuel is injected into the combustion chamber between 180° and 0° before the top dead center.
