Abstract
In an internal combustion engine with auto-ignition in which the fuel is injected directly into the combustion chamber by means of a fuel injection nozzle in the form of multiple fuel jets, wetting of the combustion chamber-side cylinder head surface is minimized by recesses formed in the cylinder head whereby some of the fuel is reflected by the piston towards the cylinder head when the piston is in a position adjacent the cylinder head and directed at least partially into the recesses formed in the cylinder head.
Claims10
An internal combustion engine having a cylinder, with a cylinder head and a piston having a piston trough, and a combustion chamber defined by the cylinder head and the piston, and a fuel injection device for injecting fuel directly into the combustion chamber, so that at least some of the fuel enters the piston trough, and at least one recess arranged on the combustion cylinder head surface for accommodating fuel injected into the cylinder head and the piston trough and reflected therefrom toward the cylinder head.
