Better fuel economy and lower emissions from gasoline direct-injection engines are getting closer. Most European automakers are preparing GDI engines for introduction in the next few years, starting ...

Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...

The internal combustion gasoline engine -- we have a love/hate relationship with it. It creates a lot of pollution. It is incredibly inefficient. It spews carbon into the atmosphere. It makes us ...

Trying to think green when buying a car? Whether your new fuel-efficient engine helps or hurts the warming planet depends on where you live and what you're putting in the tank. New cars aim to deliver ...

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 ...

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 ...

For more than a century, Americans have relied on gasoline to get us everywhere we want to go. Rarely do we think about how gasoline actually combusts in our engines. Most often, we’re concerned with ...

Twenty years ago, a group of original equipment manufacturers (OEMs) established the voluntary TOP TIER™ standard to enhance fuel detergency and optimize engine performance. Recognizing the ...

The 1955 Mercedes 300SL did more than introduce dramatic gullwing doors to the road. It quietly rewrote the rulebook for ...

The 5.3-liter V8 Ecotec3 might seem like the stepchild of the General Motors family, especially with the LS series of engines around, but it's a winner in its own right. This naturally aspirated ...

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 ...
