Ford EcoBoost: software is the secret sauce

Ford is enjoying a remarkable run of success with its EcoBoost family of engines, and there are undoubtedly many more yet to come. This press release reminds us that the ultimate success is all about software – it’s not just about slapping a turbo on the side of the engine. That approach doesn’t maximize power or fuel economy, much fewer emissions. Times have changed.

Software Emerges as ‘Secret Sauce’ to Ford EcoBoost Success

  • Powertrain control software linchpin to Ford EcoBoost® market success
  • Software engineers’ eclectic experience includes particle physics, Space Shuttle safety and laser-guided defense systems
  • Ford EcoBoost volumes, vehicle applications growing worldwide
DEARBORN, Mich., July 26, 2013 – Mike Kluzner’s experience is considered only somewhat unusual among the ranks of Ford’s in-house software engineers. Kluzner got his start designing laser weapon systems capable of disabling the navigation systems of enemy satellites.
His employer? The former Soviet Union.
Today, Kluzner designs software for onboard fuel system diagnostics on Ford vehicles sold worldwide. Kluzner holds more than 20 patents on onboard diagnostics.
“During my work for the military, I was trained very early on how to establish and maintain consistent product performance,” said Kluzner, who was born Mikhail Igor Kluzner and has lived in the United States since 1990. “This became part of my engineering DNA.
“The same process for analyzing key physical relationships works for what we do today in engine combustion, catalyst chemistry and mechanics,” he added. “These are all part of Ford’s software engineering expertise.”
Kluzner, who began his career with the company in 1996, is one of dozens of in-house powertrain control software engineers at Ford. A large part of these engineers’ jobs is to continually improve and reinvent the control strategies on Ford’s award-winning EcoBoost® engines.
Other engineers in the group have backgrounds that include designing software to detect damage to heat tiles on the international Space Shuttle, as well as work in particle physics.
The importance of these software engineers to the global expansion of the EcoBoost franchise is hard to overestimate. The software they are working on must manage and optimize increasingly sophisticated hardware in the EcoBoost engines to make Ford vehicles more powerful, cleaner and fuel efficient.
“No doubt, turbocharging, direct injection and cam timing hardware are key ingredients of Ford’s EcoBoost recipe, but the secret sauce is the software,” said David Bell, Ford global boost system controls engineer. “The hardware existed, but without our unique software and engine tuning, EcoBoost wouldn’t have been as successful with consumers.”
Secret sauce for EcoBoost
Ford’s EcoBoost engines faced several challenges when the technology first launched in 2009. One was overcoming consumers’ resistance to radically smaller engines with fewer cylinders. Another was the technical difficulty of making powerful engines while still meeting tightening emissions regulations.
Ford’s team of in-house software control engineers patented software tricks that exploit hardware advances – like the turbochargers and direct fuel injection systems – like no other car company in the world. In fact, Ford has earned or has patents pending for several of its software control technologies.
The result is a new generation of smaller, more power-dense engines that deliver the fuel economy of smaller engines while minimizing or eliminating the traditional shortcomings of turbocharged engines, including turbo lag (the delay between a driver stepping on the accelerator and the engine responding with the desired power).
“Our control software has helped us deliver a combination of power, torque, driveability and efficiency like no other automaker in the world,” said Bell. “Sometimes, the software helps anticipate demands for power before the driver even fully depresses the accelerator.”
For example, in conditions such as an anticipated transmission shift, the software tells the engine to close the throttle slightly and leave the turbo wastegate closed to maintain boost pressure ahead of an upshift. The customer never sacrifices performance.
Demand booming
Without the software engineers’ work, EcoBoost could not have succeeded in the marketplace. But by offering increased fuel economy with no zap to performance, EcoBoost has been an unqualified success. Customers are snapping up EcoBoost-equipped vehicles as fast as Ford can make them.  Sales of vehicles with EcoBoost are approaching 70,000 units per month worldwide.
EcoBoost-equipped vehicles are gaining share in the U.S. market. The take rate for EcoBoost on F-150 trucks is 42 percent, on Escape it is 89 percent and on Fusion, 52 percent.
A fifth EcoBoost variant, a 1.5-liter engine, was recently introduced to meet growing demand for powerful, more efficient vehicles globally. The award-winning 1.0-liter EcoBoost, already available in Europe, will be available this fall on the 2014 Ford Fiesta.
