Direct injection of both fuels in RCCI may offer a way to decrease HC and CO emissions without sacrificing efficiency and NOx/PM benefits

Green Car Congress

In an effort to decrease the emissions of UHC and CO while retaining the benefits of RCCI, the team, led by Professor Rolf Reitz, investigated the direct injection of both fuels, using separate injectors. This allows for stratification of the gasoline charge before any diesel is injected. Earlier post.) —Wissink et al.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). They found that at all loads, GDCI was remarkably clean, with the potential for no aftertreatment for NO x and particulate emissions.

Delphi and partners advancing with high-efficiency, low-emission gasoline compression-ignition combustion

Green Car Congress

In 2010, The US Department of Energy (DOE) selected Delphi, along with partners Hyundai America Technical Center, Inc (HATCI); Wisconsin Engine Research Consultants (WERC); and the University of Wisconsin-Madison (UW) for a $7.48-million For IMEP from 2 to 18 bar, engine-out NO x and PM emissions were below targets of 0.2

OPOC maker Achates Power now concept-ready; ready to develop multi-cylinder engines for competitive demonstrations

Green Car Congress

Currently, Achates has demonstrated a single-cylinder CI OPOC two-stroke engine that matches the engine-out emissions of an advanced 2010 medium-duty diesel while achieving specific oil consumption of less than 0.1% can meet emissions, and not just at one point where it is a novelty of science, but across the entire speed map.
