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 ...

If you flip through the list of features on just about any new car or truck, you’re likely to see the words “direct fuel injection,” or DI. The concept is straightforward enough -- engineers have ...

What is gasoline direct injection and how is it different from traditional methods of getting fuel into your car's engine? Antuan Goodwin Senior Writer, Electrified Cars Antuan started out in the ...

Despite advancements in hybrid power-trains and electrification technology, gasoline engines remain the predominant choice in passenger cars because of continued efficiency improvements, most recently ...

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 ...

How does fuel injection work? Everything you need to know about fuel injection! Throttle body injection, multipoint port injection, and direct injection. Injection techniques for both gasoline and ...

Direct injection. Just about every car has it now, and those that don’t probably will in the next few years. It can add power, reduce emissions, and is a big part of why just about everybody is ...

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 ...

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 ...

GM Powertrain announced today it will deliver a 3.6-liter V-6 gasoline engine with direct injection and variable valve timing (VVT) technologies in the 2008 model year. A vehicle application will be ...

So we wake up one day and decide we want to throw a supercharger on the C7, and while we are there let’s throw a cam in it, too! The supercharger is an air pump in front of the air pump and its ...
