If you think direct-injection diesel engines made their debut in the 1980's, think again. The first diesel without extra ...

Carburetors are old news. We've moved on to electronic fuel injection long ago. But of the two main varieties of 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 ...

Direct injection systems, in which a high-pressure fuel pump pressurizes the fuel for injection directly into the cylinder by an injector, provide greater freedom in the injection timing and volume ...

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 ...

Direct injection engines deliver fuel at high pressure directly into the combustion chamber. When the fuel spray strikes surfaces such as the piston crown or liner, a thin liquid film forms. This film ...

A Kia driver stopped into an unconventional place to get an oil change—an Advance Auto Parts—and that kicked off a conversation about a certain kind of engine and the love that it might require.

These 3-cylinder engines have proven themselves in Hondas, BMWs, Toyotas, and even Koenigseggs, delivering performance and ...

Gasoline direct injection, or GDI, is one of the most crucial bits of technology in the modern internal combustion engine. In engines equipped with GDI, highly pressurized gasoline is sprayed directly ...
