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 ...

Direct-injection engines were introduced with a promise that sounded ideal: more power, better fuel efficiency, and cleaner ...

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 ...

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 ...

Ford of Europe will install gasoline direct-injection, spark-ignition engines into some of its smaller vehicles beginning in 2003. Called Duratec SCi - for Smart Charge injection - the engines feature ...

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 ...

Chevron says its new Techron cleans GDI injectors better, plus new rewards make switching easier.

Yuchai ammonia engine uses high-pressure direct injection and onboard ammonia-to-hydrogen generation for heavy-duty vehicles.

Direct injection engines deliver fuel at high pressure directly into the combustion chamber. When the fuel spray strikes surfaces such as the piston crown or liner, a thin liquid film forms. This film ...
