Abstract
A reciprocating lens-like combustion space is formed in a piston internal combustion engine which is located with approximately one-half in a recess of the piston top and with approximately the other half in the cylinder head. By the dimensioning of the combustion space and the coordination thereof to the inlet and exhaust valve, a vortex flow is produced with a ring-shaped mixing zone of high fuel concentration, in which the ignition electrodes of two spark plugs are arranged diametrally opposite one another.
