A spark plug includes: a center electrode, a ground electrode, which is side-mounted on the center electrode, and a noble metal insert, which is situated on the center electrode. The method includes the steps of: receiving fuel into a fuel rich pre-burner ; receiving high concentrations of hydrogen peroxide into the pre-burner ; converting the fuel and hydrogen peroxide into a fuel rich gas; and passing the fuel rich gas through a turbine, thereby using high concentrations of hydrogen peroxide to drive the turbine. A liquid coolant is delivered into the inlet manifold via an inlet fitting. This error condition includes the occurrence of excessive collisions or late collisions.
