English term or phrase:cylinder cutout
The steps of 620 through 650 comprise the fuel system protection technique of cylinder cutout.
In step 620 a cylinder is selected (the cutout cylinder) in which only directly injected fuel will be introduced, while in the remaining cylinders only fumigated fuel is introduced.
The selection of the cutout cylinder can be made based on load conditions or on regions in the operating map of engine 100.
Fumigation system 120 controls the introduction of the fumigated fuel into specific cylinders.
In the present embodiment fumigation system 120 enables this approach by utilizing port fuel injectors.
Actuation of direct fuel injector 130 in the cutout cylinder allows fuel flow through supply system 140 and through injector 130 into this cylinder.
After the selection of the cutout cylinder the technique begins.
In step 630 when engine operating conditions change control is passed back to step 620 where the cutout cylinder is again selected.
It is also possible that the cutout cylinder can be switched in and out of fuelling with directly injected fuel only according to engine operating conditions.
