ABSTRACT:
An internal combustion engine comprising a piston having a top face with a depression formed therein, and a first fuel injector and a second fuel injector arranged on the inner wall of the cylinder head. Fuel is injected from the first fuel injector when the position of the piston is high, and fuel is injected from the second fuel injector when the position of the piston is low. The axes of fuel injection of both fuel injectors are determined such that fuel injected from the fuel injectors is directed to the central portion of the depression.
