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?

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 power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, ...

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 ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...

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 ...

While Hyundai and Kia have been rolling out impressive new EVs like the Ioniq 5 N and Kia EV9 and redesigning existing models like the Sonata, the automaker still has the lingering problem of bad ...

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 ...

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 ...
