Disclosed is a diesel engine comprising a cylinder head; a combustion chamber within the cylinder head, the combustion chamber being in the shape of a bowl; and a piston having a piston crown, the piston crown having a dome-shape for protruding within the cylinder head during a combustion operation near or at top dead center. The engine is preferably a two stroke crankcase compression engine. Use of a combustion chamber in the shape of a shallow bowl along with other parameter selection decreases the rates of combustion pressure rise while providing reasonable power output.
