Advanced features include five angle intake seats and back cut valves that provide shear points for the fuel to go into suspension as it enters the combustion chamber. The spark plugs are located as close to the top and center of the combustion chambers as possible, shortening the distance that the flame front must travel and producing a more uniform pressure rise in the cylinder.
