Shou L. Hou is the patent inventor for the fuel delivery technology. Ford began talks with Hou and TMC over two years after the patent was filed.
The specific direct injection technology patented by Hou is the dynamic range of the fuel injection which maximizes performance while minimizing fuel waste. This system is said to conserve fuel by 25 percent in city driving, while offering improved power when needed.
The EcoBoost engine representd 42 percent of the F-150 sales in the month of July. Ford began offering this engine in early 2011, after apparently telling TMC and Hou that it had no interest in utilizing their patent.
