Fuel injection offers drivers increased efficiency and power. But there's a common problem, too: carbon buildup on the engine ...

The engine is about the size of a dime and, like all ion engines, produces tiny amounts of thrust. In fact, the researchers liken it to half the weight of one sesame seed from a hamburger bun.

The NEXT ion engine fires at peak power during testing at NASA's Glenn Research Center An ion engine has smashed the record for total thrust in a NASA test. The successful test means the engine ...

This isn't surprising, since in many ways it resembles the first ion engine that flew on the unsuccessful Soviet Zond 2 Mars probe that launched in 1964.

Most automakers use GDi engines somewhere in their lineup. They usually have special names or badges to denote that they're GDi. For example, Kia puts GDi badges on vehicles that use the technology.

Direct-injection engines improve performance and save fuel, but at a price Cars with this technology might end up in the repair shop more frequently. Published: February 17, 2015 02:30 PM.

The drawback is the very low thrust of an ion engine. That's why past satellites have carried conventional thrusters as well. Upon delivery to orbit, ABS-3A used its ion thrusters to reach a ...

It has been touted as the automotive holy grail, the ultimate marriage of better performance and greater fuel economy. It’s the direct-injection (DI) engine, the latest technology designed to ...
