FEV to show compressed natural gas light-duty concept engine with ATAC combustion system at 2011 SAE World Congress

Green Car Congress

FEV developed ATAC more than a decade ago, targeting large-bore engines in stationary and heavy-duty applications. The lean burn combustion process also offers significant improvements in fuel consumption and CO 2 emissions in comparison with more conventional CNG technology as a result of dethrottling and better combustion efficiency.

New split-cycle concept to control diesel HCCI combustion

Green Car Congress

Pollutant emission behavior vs. engine speed.confirms the validity of the HCPC combustion concept. Emissions are almost independent of the engine speed. Soot and HC are orders of magnitude lower than the ones of a diesel engine. emissions are almost constant and similar to those of a diesel engine.
