Abstract

A combustion chamber (11) shaped as a solid of revolution is arranged in the piston crown (7) or cylinder head (8) and fuel is injected in the form of a conical shell by an injector 10 having a poppet valve member (5), Figure 1 (not shown), so that the air in the combustion chamber (11) is divided into two substantially equal volumes (12, 13). Squish flow of the combustion air produces very good mixing of the air and fuel, thus improving combustion. <IMAGE>
