An internal combustion engine comprises an engine housing which defines a main combustion chamber that is separated from a precombustion chamber by a flame communication passageway. The engine housing further defines a fuel supply passage with one end and an opposite end. A source of fuel is fluidly connected to the opposite end of the fuel supply passage. A check valve which includes a valve body with a valve seat and a valve member is positioned between the one end of the fuel supply passage and the precombustion chamber. The valve member is movable between an open position and a closed position. The valve body and the valve member define a relatively wide fluid passage that fluidly connects the fuel supply passage to the precombustion chamber when the valve member is in the open position. The valve body and the valve member define a relatively narrow stagnation region separating the valve seat from the precombustion chamber when the valve member is in the closed position.
