Putting the Engine in Engineering

The internal combustion engine has a lot more to offer the mobility industry as an energy efficient, low-emissions powertrain option. And Mr. Mike Kaput is coming out of his recent retirement from Ford Motor Company to prove it.

“Internal combustion engines will see rail pressures of 500 bar and more to optimize the gasoline combustion process,” said Kaput. “Higher injection pressures can help engine designers reduce tailpipe emissions for upcoming EU7 and SULEV regulations. Combustion engines will also continue to play a major role in hybrid electric vehicles, while the move to full electric vehicles plays out through 2040 and beyond.”

Mike recently joined the Stanadyne team in early 2021 after working on engine programs for Ford Motor Company for 35 years. He brings extensive knowledge of global engine programs and fuel components to Stanadyne as the company’s Director of Design Engineering for Gasoline Direct Injection. In his new role, he is developing of high-pressure injectors and fuel delivery systems.

“I came back to work after three months of retirement because I feel like I still had more to give,” said Kaput. “My energy and enthusiasm for developing robust fuel systems is still there. I call it my ‘happy place.’”

Mike puts the “engine” in “engineer,” as he was Ford’s global lead engineering expert for all engine fuel injection systems, which included gasoline, diesel, compressed natural gas (CNG), and liquid propane gas (LPG) fuels. He has worked on more than 125 global vehicle applications and received a Society of Automotive Engineers (SAE) Gold award in 2010 for his contributions to developing Ford’s LPG engine in Australia.

During his career at Ford, he wrote the company’s engineering specifications for all gas-related, on-engine fuel components, which covered low pressure injector, direct injection injector, fuel rail, fuel pump, pressure regulator, pressure sensor and high-pressure lines. On many occasions, he was asked to share his vast engine expertise and experience both inside and outside of Ford. He taught engine fuel system classes at Ford for more than seven years and was a chair of the SAE Fuel Injection Committee.

“One of my proudest accomplishments during my time at Ford was my role in developing Ford’s roadmap for migrating from welded and brazed fuel rails to forged rails for high-pressure DI systems,” said Kaput. “Over the years, I also have had the privilege to guide fuel rail suppliers through the PPAP process and the creation of robust manufacturing processes to support Ford business.”

Mike has a bachelor’s in Electrical Engineering from The University of Michigan – Dearborn, in Dearborn, Michigan and a master’s in Engineering Management from Wayne State University in Detroit.

Stanadyne’s High-Pressure Pro

Srinu Gunturu

Stanadyne’s Senior Manager of Engineering for Gas Products, Srinu Gunturu has been raising the bar for high-pressure gasoline direct injection fuel systems since joining the company eight years ago. Based at Stanadyne’s Gasoline Advanced Engineering Center of Excellence, in Jacksonville, North Carolina, he and the Gasoline Advanced Engineering team are solving the pump performance, packaging, and durability issues challenging the industry today and tomorrow.

 

“We are solving the fundamental challenge of how to deliver the most fuel using the smallest package to optimize engine efficiency and reduce emissions,” said Gunturu. “Engine downsizing requires fuel pumps to be increasingly compact to fit in ever-tightening spaces under the hood. That means higher pressures and maximizing low and high speed overall volumetric efficiencies.”

Stanadyne 500 Bar PumpSrinu is one of the lead developers of high-pressure GDI pumps ranging from a 150-bar system that currently is in the market to future 1000 bar systems. He currently is testing Stanadyne’s newest 500 bar design that offers reduced noise and increased overall volumetric efficiency – even at low speeds. It has a robust pumping structure, patented floating sleeve, and separate spring design. In addition, it features a low-profile accumulator for improved engine packaging.

“Our patented floating sleeve eliminates scuffing and seizure by reducing side loading on the plunger,” said Stanadyne’s High-Pressure Pro, Srinu. “This makes for a very durable, quiet GDI fuel pump.”

Defying Expectations, No Matter the Challenge

Case Study: Engineering a single pump GDI solution for V6 and V8 engines

When you need a solution quickly, you want a versatile partner who can solve the problem, based on the unique task at hand. For decades, Stanadyne has approached some of the world’s most complicated fuel system challenges with a flexible product strategy that delivers custom fuel pump solutions.

Having access to cutting-edge technology is essential to stay ahead of the curve in the automotive industry – but it isn’t the only necessity. At Stanadyne, we understand that every engine manufacturer has unique requirements for their GDI applications, and frequently, tough challenges to overcome. That’s why Stanadyne works closely with customers to tailor customized solutions that solve the toughest challenges with innovative solutions. This approach combined with decades of experience gives you an award-winning strategy.

SP1250 GDI Pump

Customer Challenge
It was this strategy that helped Stanadyne forge a successful partnership with a well-known, global OEM. In 2004, Stanadyne was approached by this OEM to help them to develop a unique single-pump solution for their V6 and V8 engines.

To meet the fuel delivery requirements for engines of this size, most GDI systems use two high-pressure pumps. But for this customer, there were unique requirements that made it difficult to install a two-pump system without cost and efficiency ramifications.

Stanadyne Solution
Stanadyne embraced the challenge, and by 2013 launched the first single pump solution for high-displacement, high-horsepower applications on trucks and SUVs. The SP1250 not only met the displacement requirements of the engine but was designed with several features that exceeded the customer’s expectations for performance, including a patented floating plunger sleeve mount, a beehive spring design and the first generation of our QuietTechTM metering valve technology.

Our patented floating plunger sleeve mount isolates mounting loads and the plunger bore, which allows for low clearances between the plunger and sleeve. The plunger and sleeve are match fit to a clearance of less than 8 micron, which enables industry-leading volumetric efficiency and pressure rise rates at cranking for fast engine start times.

Another feature that was designed for the pump is a dual, or beehive, spring. An outer spring to handle tappet loads and a smaller inner spring to handle plunger return. Separating these spring loads led to a more robust pump due to the minimized plunger side loading and improved tolerance to spring out-of-squareness.

The SP1250 was also among the quietest pumps on the market at the time of its development thanks to our QuietTech package of technology. From the inlet valve to the control valve, the internal hydraulics of this pump were optimized to address radiated and transmitted noise.

In conjunction with this pump development, Stanadyne also developed a larger single-pump solution for high-performance engines up to 650 HP. The SP1550-200 uses similar design concepts as the SP1250-200 I, but delivers even higher output for powerful sportscars. The SP1550 can supply up to 1550 mm3 of fuel per engine revolution, making it the highest output GDI pump on the market.

Result
Since its launch in 2013, more than 5 million SP1250 and SP1550 pumps have been manufactured, and both have proven to be among the most dependable fuel injection pumps in the world.

Stanadyne continues to raise the bar for fuel injection technology by continuously developing new ideas for the future of GDI pumps. The next generation of the SP1250 pump, which is scheduled to begin production this month, is engineered to be even lighter, quieter and more efficient than ever.
