Method of operating an internal combustion engine

摘要

In a method for the operation of an internal combustion engine either on all cylinders (as full engine) or with only some cylinders in operation (cylinder cut-off), the cylinders are divided, in the firing order, into two groups of alternating cylinders which are selectively operative with an angular ignition spacing twice that of the cylinders of the engine when operating as full engine, the two groups of cylinders being activated alternately during engine operation with cylinder cut-off.
