Ford Motor Company has filed more than 100 patents seeking to protect its EcoBoost engine, which promises to drive the next generation of more fuel-efficient gasoline engines. The engine combines direct fuel injection and turbocharging to get more horsepower with less fuel, allowing smaller engines to drive larger vehicles and boosting the average fuel economy of Ford’s fleet. But as the Detroit News reports, other carmakers dispute the unique nature of Ford’s system:
But other automakers have been combining those two technologies for years, albeit for different reasons. First used to boost the power of high-performance motors, the Germans began selling mainstream vehicles with gasoline powered turbo direct-injection engines before Ford even unveiled its system.
“If I were them, I’d be more worried about VW coming after me than the other way around,” said analyst Jim Hall of 2953 Analytics LLP in Birmingham, adding that Volkswagen AG had similar engines on the market before Ford. “There are certain parts of this you just can’t patent.”
Ford says that the key is in the control system that they developed, which allows fuel injection levels to be adjusted hundreds of times per second.
