China-based Weichai Power’s WP15 hydrogen direct-injection engine has qualified under the China VI vehicle ...

Weichai Power (HKG:2338) announced that its independently developed WP15 hydrogen direct‑injection engine for heavy-duty ...

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

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 ...

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 ...

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 ...

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 ...

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 ...

Gas has been expensive of late. Have you been tempted to stray away from Top Tier fuels in favor of a warehouse brand’s ...

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 ...

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.
