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.
