Q: Numerous articles were published (including yours) in the past suggesting that direct injection gas engines might experience drivability problems at higher mileage due to deposits building up on ...

The other day I dropped my car off at a European specialist shop, and while I was there, a technician was working in the engine bay of a Mk7 Golf R, cleaning out carbon deposits off the intake valves.

With direct injection, engines can run with higher compression ratios, higher boost, and higher efficiencies. The marvel has lead to widespread downsizing of engines, ditching large naturally ...

The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, an engine’s efficiency is dependent on a precisely calculated air-to-fuel ...

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 ...

While many of its rivals are offering direct injection technology on its engines in an effort to boost performance and fuel economy, Ford decided on skipping on the innovative technology for its ...

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.
