Abstract
A method and apparatus for controlling a fuel injector assembly of an internal combustion engine during cold operation thereof is disclosed. If a combustion-absent condition is detected in one or more of the cylinders associated with the engine, an engine control module cuts out the affected cylinders thereby preventing additional fuel from being delivered to the cylinders for a predetermined period of time, such as 4-5 seconds. During the period of time in which the cylinders are cut out, the pistons in the remaining cylinders associated with the engine continue to operate thereby heating the engine block. After the predetermined period of time, fuel is again injected into the cylinders if a combustion-present condition is detected therein.
