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 ...
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 ...

Why some engines have both port and direct injection
Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...
Most new petrol cars you see today are equipped with fuel injection systems or injector motors. These have almost wholly supplanted older carburetor motors. They are more reliable, effective, and ...
But the industry shift didn’t happen without complications; these new engines have faced three big challenges: chain wear, fuel dilution, and LSPI. In this video we’ll discuss the differences between ...
SAE International Journal of Engines, Vol. 13, No. 1 (2020), pp. 77-92 (16 pages) At gasoline direct injection, light-duty engines operated with homogeneous, stoichiometric combustion mode, ...
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 ...
