Passenger car gasoline engine design has experienced a dramatic shift in fuel injection technology over the last ten years. A previously unconventional fuel injection design, called gasoline direction injection or GDI, is now used in approximately 50% of all new gasoline-powered cars and light-duty trucks sold in the U.S. and other major automobile markets around the world.
GDI is actually not a new technology, having been around since about 1900 when the first gasoline engines were invented. However, this technology did not begin to see widespread use in automobile production until about the mid-2000s.
Afton’s Road to GDI
Prior to this recent widespread GDI introduction—as far back as the mid 1990s—Afton was working on leading edge research to develop fuel additive technology uniquely tailored to these engines. GDI engines are fundamentally different than conventional carbureted and port fuel-injected engines and not surprisingly, create different types of deposits that require new types of fuel additive chemistry solutions that protect against power-robbing deposit formation and ensure clean and efficient operability.
Afton’s comprehensive work to address new challenges with GDI engine designs, frequently in cooperation with major automakers, Tier 1 OEM suppliers and major oil companies, is well documented in multiple peer-reviewed journal publications dating back to 1999. In some of this early research, Afton engineers and scientists had to develop custom engines with GDI technology in our own laboratories and workshops because commercial engines with GDI technology were not available for sale to the general public.
Since then, Afton has been providing additive technology for GDI engines, initially using a Nissan-based engine adapted to GDI and thereafter a Mitsubishi engine and various other vehicles. Our innovative product solutions, test knowledge and technology insights have shaped the industry as we know it today. However, Afton won’t stop there. Just as automakers continue to introduce evolving and increasingly sophisticated GDI engine technology, Afton continues to work on developing leading-edge additive solutions to ensure optimal performance of gasoline engines for the foreseeable future.
