"What is Nautilus doing differently?
Nautilus CEO Riley has a different idea. Rather than the sophisticated and expensive sensors and direct injection system, Riley is using a single, inexpensive throttle body fuel injector at the entrance to the intake manifold. He claims that this approach ensures that the air and fuel are thoroughly blended into a homogeneous mixture by the time it reaches the cylinder. The real magic is in the cylinder with the piston and combustion chamber design."
