Abstract
A control system of an internal combustion engine enabling effect production of hydrogen and reliable promotion of burning of ammonia by a simple structure. The internal combustion engine uses ammonia as a fuel and is provided with a fuel injector injecting fuel into an intake passage and a variable operating mechanism able to change a valve opening operation of the intake valve. In the exhaust stroke, this temporarily opens the intake valve. Ammonia for hydrogen production is injected from a fuel injector into the gas flowing back at this time from the combustion chamber to the inside of the intake passage. As a result, hydrogen is produced from the ammonia. In the following intake stroke, this hydrogen is fed into the combustion chamber together with the ammonia and is burned together with the engine drive use ammonia.
