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 ...

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

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 ...

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

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.

While significant sooty black deposits—and even, occasionally, visible puffs coming from the tailpipe—used to be a sign your gasoline car needed a tune-up, they’re a normal fact of life with many ...

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 ...

Until the early 1990s, many gasoline engine designs relied on carburetors to produce the fuel-air mixture needed to make the power that makes a car move. However, as the regulations around fuel ...

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 ...

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

Knowing the inner workings of a vehicle comes with its set of benefits. You know the risks associated with potential issues, understand the causes, and can quickly fix things DIY-style. It is ...
