Abstract: A method is provided for operating an internal combustion piston engine, in which fuel is injected directly into a working chamber in the form of a pre-injection and main injection by means of an injection nozzle with a plurality of injection holes. The pre-injection takes place in a clocked manner. In order to minimize the moistening of the walls of the combustion chamber, a higher fuel pressure prevails in an injection device during the main injection than during the pre-injection. Furthermore, optimum homogenization of the pre-injected quantity of fuel is obtained by restricting the range of the injected fuel jets while simultaneously maximizing the atomization of the fuel particles and reinforcing the disintegration of the fuel jets during the clocked pre-injection.

Abstract: In a method for the injection of Diesel fuel into a combustion chamber of a Diesel engine by way of a fuel injection valve with a plurality of pilot and main fuel injection ports, the fuel is injected during partial load operation only by way of the pilot injection ports such that a homogeneous mixture is formed and, under full load operation, fuel is additionally injected—after a pause—through the main fuel injection ports in such a way that a fuel jet bundle is formed in combination with the fuel jets formed by the pilot ports which is extends over the whole periphery of the combustion chamber. The fuel injection valve has the main fuel ports arranged in a piezo-actuated tappet in series in the direction of the opening movement of the tappet behind the associated pilot ports. With the piezo drive the opening stroke of the tappet can be controlled so as to provide fuel injection pauses between the pilot fuel injection and the main fuel injection.
