✦ Synopsis
The ECOS-DDF system is a diesel fuel ignition type natural gas engine, which ignites and burns the mixture of natural gas with a self-ignition #ame of a small amount of diesel fuel injected directly into the combustion chamber. This engine, "tted with an EGR cooler and the new reverse-#ow catalytic converter, controls the injection timing and the supply volume of natural gas and of diesel fuel respectively with the most optimized balance. As a result, it achieved nearly equal thermal e$ciency to the base diesel engine, while decreasing harmful exhaust emissions.
