This study investigates the formation of wall films in direct injection engines, a key factor in particulate matter generation. The results show that cold fuel adheres more to the wall creating ...

SAE International Journal of Fuels and Lubricants, Vol. 7, No. 3 (November 2014), pp. 792-802 (11 pages) ABSTRACT Ethanol direct injection (EDI) is a new technology to use ethanol fuel more ...

It has been touted as the automotive holy grail, the ultimate marriage of better performance and greater fuel economy. It’s the direct-injection (DI) engine, the latest technology designed to squeeze ...

The fuel injection pressures used in gasoline direct injection (GDI) engines have increased in recent years to improve fuel efficiency and reduce emissions. Current GDI engines use injection pressures ...

If you flip through the list of features on just about any new car or truck, you’re likely to see the words “direct fuel injection,” or DI. The concept is straightforward enough -- engineers have ...

When port fuel injection (PI) first debuted in the mid-1980s, no one knew what to make of it. With no carb or distributor to adjust, it was a steep learning curve for hot rodders and the performance ...

The carbureted car and truck era phased out by the early '90s. Carbs are still in use today on a few motorcycles, lawn mowers, and other power equipment, but electronic fuel injection (EFI) is ...
