Direct-injected engines helped modern vehicles produce better fuel economy and stronger performance, but mechanics are ...

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 ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Turns out the old technology did a few things no computer has matched.

China Yuchai International Limited (NYSE: CYD) ("China Yuchai International" or the "Company"), one of the largest powertrain solution manufacturers through its main operating subsidiary in China, ...

Direct injection systems, in which a high-pressure fuel pump pressurizes the fuel for injection directly into the cylinder by an injector, provide greater freedom in the injection timing and volume ...

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 study reveals the mechanisms behind wall film formation, a key contributor to particulate matter emissions under cold fuel conditions The growing concerns about air pollution and its harmful ...

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 ...
