Abstract

A four stroke engine cylinder head (16) has two inlet pipes (19 and 22) which contain alternate acting inlet valves (14 and 15). Fuel/air induction strokes through valve (14) alternate with air only induction strokes through valve (15) giving an eight stroke cycle under half load. When gate valve (23) is moved by a control to the dotted position, this seals the air only inlet and opens port (25) to give fuel/air induction strokes over half load and a four stroke cycle. Air only induction strokes or eight stroke cycles under half load may also be achieved by cutting out some fuel injectors or injection strokes as the load permits.
