Fuel injection strategy for internal combustion engine, involves injecting fuel in cylinder of engine, and discontinuing additional fuel injection after ignition process, during initial start of engine

摘要

The strategy involves injecting fuel in a cylinder of an internal combustion engine, based on a preset start injection strategy, during start of the engine. Additional fuel injection is discontinued after an ignition process, during initial start of the engine. The additional fuel injection is discontinued until detectable combustion occurs in the cylinder and/or fuel injection is detected. The additional fuel injection is performed according to a mask provided in the cylinder or a cylinder group.
