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

Removing carbon build up from your direct injection gasoline engine is easier than you might think! I'd always heard that you ...

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

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 ...

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 world is looking mighty volatile these days, so there are plenty of reasons why you should be concerned with your car's engine longevity. Whether you're trying to sustain a higher-mileage car to ...

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 ...

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 ...

Flash boiling occurs when liquid fuel under high pressure enters an environment whose pressure lies below the liquid’s saturation pressure, driving rapid vapour nucleation and explosive atomisation.
