Gregg Petersen's Hilborn-injected Chevette. The first thing you should understand is that direct-port, constant-flow fuel-injection—Hilborns, En-derles, Crowers, whatever—were never designed, nor ...

The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind ...

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 ...

Port fuel injection and direct injection are similar but distinct systems, so why do some engine designs include both?

Modern engines are cleaner and more efficient than the ones you grew up with, yet many drivers are discovering a new headache ...

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 ...

Gasoline direct injection, or GDI, is one of the most crucial bits of technology in the modern internal combustion engine. In engines equipped with GDI, highly pressurized gasoline is sprayed directly ...

The University of Wyoming’s Center of Innovation for Flow through Porous Media (COIFPM) is accepting proposals for research grants as part of the Wyoming Gas Injection Initiative (WGII). Oil and gas ...
