ABSTRACT:
A fuel injection and precombustion chamber arrangement for internal combustion engines comprising a pair of concentric poppet valves. The outermost valve is arranged to open and close the precombustion chamber to the internal combustion engine cylinder. The innermost valve is arranged to open and close a chamber, formed in the outermost valve body, to the cylinder and to place a fuel-filled annular groove on the spool of the innermost valve in communication with the precombustion chamber and the chamber in the outermost valve such as to mix air flowing through the chamber of the outermost valve from the cylinder fuel and inject into the precombustion chamber the fuel contained in the annular groove in an atomized state.
