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 ...

HPDI 3.0 is here, promising a new era for natural gas engines. This next-gen high-pressure direct injection technology is an ...

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 ...

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 ...

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 ...

When your service adviser recommends getting your fuel injection serviced, is it just a money grab? The answer depends on how your engine was made.

A new experimental study shows that overlapping diesel pilot and natural gas injections in a heavy-duty HPDI engine raises ...

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 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 ...
