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 ...

NI DI Driver Systems come in 3-, 6-, 9- and 12-channel versions (2, 4, 6 and 8 channels, respectively, when used with piezoelectric DIs). System accessories include NI 9215 and Drivven Port Fuel ...

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 ...

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 ...

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 ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Electronic fuel injection. These three words can strike fear in even the most seasoned automotive technician. The reality, however, is that no carbureted induction system can match the fuel-metering ...

We often talk about the benefits of fuel injection on off-road vehicles. Generally, these systems run more reliably than carbureted systems, but they are, at the end of the day, a bit more complex ...
