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 ...

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 ...

Automotive engineers are very good at incremental improvements to existing technologies, and that skill will be much tested in meeting increasingly stiff fuel-economy rules between now and 2025. For ...

Diesel injectors have gotten increasingly complex over the last twenty years of diesel development, but their basic design is fairly simple. Diesel fuel from the injection pump enters the mechanical ...

Just like we predicted a few weeks ago when the specs for the new Toyota HiLux were released, the Land Cruiser Prado is getting a new 2.8-liter turbodiesel engine, a brand-new one with direct fuel ...

Direct fuel injection isn't exactly a new idea. It's actually been around since World War II, when it was used on aircraft engines designed by the Germans and Russians and has been used in diesel ...
