Abstract

A method of reducing nitrogen oxide (NOx) emissions of a four-stroke turbo-charged piston engine by injecting water or steam into the combustion chamber of the engine, wherein the water injection is carried out at least substantially during the intake stroke of the engine. The injecting of water is initiated at the earliest when the inlet valve has moved through about 50% of the total range of its opening movement.
