Fuel is injected directly into the cylinders vice the intake manifold. Allows for more accurate metering of fuel and control of AFR's. Downside is typically an increase in price due to higher temperatures and pressures the injectors must withstand.
Another issue, I've read, is carbon buildup on the valves, as there's no wash of fuel over them to clean them up.
