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 ...

But the industry shift didn’t happen without complications; these new engines have faced three big challenges: chain wear, fuel dilution, and LSPI. In this video we’ll discuss the differences between ...

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 ...

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 ...

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 ...

Direct injection has been considered the most effective approach to overcome the inherent short-circuiting of fuel in a two-stroke engine. A practical application of this technology on an 1100cc ...

There's a new acronym floating around the performance industry—GDI—and it stands for gasoline direct injection. Among domestic production engines that have jumped heavily into the GDI segment are the ...

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 ...

Every new car sold in the United States today uses fuel injection, but not all fuel injection systems are the same. Some cars use port injection, while others use direct injection. Some even use both.
