Abstract: An internal combustion engine is provided which has an exhaust gas turbocharger and an exhaust gas recirculation device and in which the distribution of recirculated exhaust among individual cylinders of the internal combustion engine is different, whereby a partial number of the cylinders of the internal combustion engine receives all or most of the recirculated exhaust, and the remaining cylinders receive little or none of the recirculated exhaust. The internal combustion engine is preferably embodied as a diesel engine for use in trucks.

Abstract: An internal combustion engine is provided which has an exhaust gas turbocharger and an exhaust gas recirculation device, and in which valve control times of intake valves and/or outlet valves of the individual cylinders of the internal combustion engine are different. Cylinders which supply an exhaust gas recirculation device have shorter valve overlap times or none at all in comparison with cylinders that do not supply the exhaust gas recirculation device. The internal combustion engine is preferably embodied as a diesel engine for truck applications.

Abstract: A combustion chamber arrangement and a method for the same, having a piston with a combustion trough adjacent an end thereof and a fuel injection nozzle for injecting fuel through nozzle holes against boundary walls of the combustion trough. The number of nozzle holes is based on the specific characteristics of the combustion trough depth, diameter and a dimensionless constant representation of the spin number of the combustion air entering the combustion trough.
