Abstract: An apparatus for a diesel engine in a motor vehicle includes a base and a plurality of ducts positioned on the base. The base is positioned about a fuel injector. When the fuel injector injects a plurality of fuel sprays into a cylinder of the diesel engine, some of the plurality of fuel sprays are directed by the plurality of ducts into the cylinder.

Abstract: A method and controller provide a corrected standard characteristic curve for a fuel injector to inject fuel into an internal combustion engine. A minimum fuel injector energizing time is determined where a predetermined parameter based upon a plurality of fuel injector energizing times and a plurality of master fuel injector energizing times is a minimum. An energizing time correction value is the difference between a reference energizing time and the minimum energizing time. The standard characteristic curve is corrected based on the energizing time correction value.

Abstract: A method and control apparatus configured to correct a standard characteristic curve of a standard fuel injector of an internal combustion engine. First and second injected fuel quantity corresponding to an energizing time which is higher than a reference energizing time are determined from the standard characteristic curve. A standard fuel quantity increment is calculated as the difference between the second and first injected fuel quantities associated to the reference energizing time.
