Cost and complexity are discouraging Hyundai from applying direct injection to small engines. Direct injection reduces fuel consumption and emissions and in some applications boosts engine performance ...

What is gasoline direct injection and how is it different from traditional methods of getting fuel into your car's engine? You may have read or heard one of your favorite Car Tech editors talking ...

Direct-injection engines were introduced with a promise that sounded ideal: more power, better fuel efficiency, and cleaner emissions, all from a more precise way of delivering fuel. On paper, the ...

The video explains how modern direct-injected engines can develop fuel dilution, carbon buildup, oil consumption and PCV ...

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 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 ...

Discussions of direct fuel injection are almost entirely focused on diesel engines. Increasingly, however, direct injection is being utilized in gasoline engines ranging from the one in the family car ...

At ConExpo 2023, Liebherr presented a hydrogen direct injection solution for heavy-duty combustion engines. With this technology, the company aims to achieve maximum power density equal to the one of ...

Even in Mitsubishi's heyday of motorsport, when it dominated world rally stages with Tommi Mäkinen and tackled the desert dunes of the Paris-Dakar rally, the Japanese brand would not have been one you ...

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 ...

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 ...

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 ...
