A double poppet valve apparatus is mounted in a combustion chamber wall. A port is formed in the wall. A first valve member is mounted in the port. A second valve member is concentrically mounted within the first valve member. One or more resilient members are provided for urging each of the valve members into respective seated positions. The first valve member is moved in a first direction and the second valve member is moved in a second direction opposite the first direction. The valve movement is effected by a cam operably engaged with a pair of rocker arms each of which is associated with one of the valve members.
