...the "new" Toyota 2ZR-FE 1.8L engine is Spark-Ignition Direct Injection (SIDI) which is combination of diesel-like injection directly into the cylinder but using normal spark ignition, rather than compression-ignition. One side benefit is that slightly higher compression ratio is possible (better economy and power) because (a) only AIR travels through intake manifold and past the values, and (b) fuel vaporization occures inside the cylinder and cools the charge mass.

...Toyota has an Japan-SAE paper out on development of this engine.

...GM implemented same thing on the 260 HP 2.2L turbo engines in HHR, Cobalt and Solstice.
