Turbo Fuel Stratified Injection technology for gasoline engines was once a remarkable innovation that has since become quite commonplace. Traditional fuel-injected engines that don't use direct ...

The internal combustion gasoline engine — we have a love/hate relationship with it. It creates a lot of pollution. It is incredibly inefficient. It spews carbon into the atmosphere. It makes us ...

There's a new acronym floating around the performance industry—GDI—and it stands for gasoline direct injection. Among domestic production engines that have jumped heavily into the GDI segment are the ...

Gasoline direct injection has quickly become a must-have technology for automakers, who are preparing to meet the 35.5 mpg federal standard for the 2016 model year. In 2010, about 10 percent of light ...

Delphi is developing an engine fuel injection technology that could improve the fuel economy of gas-powered cars by 50 percent, potentially rivalling the performance of hybrid vehicles at less cost.

The earliest and simplest type of fuel injection, single-point simply replaces the carburetor with one or two fuel-injector nozzles in the throttle body, which is the throat of the engine’s air intake ...

Automotive engineers are very good at incremental improvements to existing technologies, and that skill will be much tested in meeting increasingly stiff fuel-economy rules between now and 2025. For ...
