Modern trucks rely heavily on precise fuel delivery systems to maintain performance, fuel economy, and emissions control.

Westport Innovations Inc. on Tuesday announced a second-generation high-pressure direct-injection natural gas system usable on original equipment manufacturers’ diesels. It replaces the dual-fuel ...

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 ...

It's an amazing time when there's new technology in the industry as it forces a new rivalry in speed parts, and direct-injection is firmly in the high-performance arena whether anyone likes it or not.

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 key ingredient to maximizing the peak performance of a diesel engine is increasing the amount of diesel being burned. On old mechanical-injection engines, the only way to do this was to modify the ...

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 ...

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 ...

Sandia National Laboratories researchers (left to right: Nathan Harry, Christopher Nilsen, Drummond Biles, and Charles Mueller) show off their prototype of ducted fuel injection module for diesel ...
