New Scientist | Evolution of the Car: "They found that 90 per cent of the fuel was concentrated in a thin jet behind the V-shaped shock wave, with the densest concentration of fuel right behind the shock front. And while the gas in the chamber slowed down the leading edge of the fuel jet, the trailing edge moved several times faster, at supersonic velocity. As the tail end of the fuel jet caught up with the leading edge, most of the fuel became concentrated in a blob just behind the point of the shock cone. 'Nobody knows why that should be, but we're going to try and find out,' Wang told New Scientist."
