Abstract

An internal combustion reciprocating piston engine is provided with a single overhead camshaft (26) which operates six valves associated with a single combustion chamber (14) by desmodromic valve gear. As viewed in a direction along the camshaft, the valves are mutually divergent in the direction from the camshaft towards the combustion chamber and some valve pairs are more divergent than are other valve pairs.
