FEV to show off lean-burning CNG engine at SAE World Congress

Filed under: , ,

FEV lean burn CNG engineAdvanced powertrain developer FEV Inc. will show off its lean-burning, compressed natural gas-fueled engine concept at the 2011 SAE World Congress. The unusual mill has been modified to run on CNG and is designed for use in light-duty vehicles. FEV says that the concept engine demonstrates that a conventional diesel mill can be altered in such a way that it can achieve the same level of efficiency and power while burning CNG instead.

FEV's Advanced Turbulence Assisted Combustion (ATAC) system involves modifications to the cylinder head, combustion chambers, pistons and intake system of the base diesel engine, a Volkswagen 2.0-liter TDI. FEV's lean burn combustion setup offers improved fuel efficiency and CO2 emissions when compared to conventional CNG technology.

The key to the efficiency of FEV's engine technology is its optimized compression ratio, which is adjusted so that it falls between the normal compression ratios of diesel and gasoline engines. FEV's lean-burning CNG-fueled concept engine will be on display from April 12-15 at the Cobo Center in Detroit, MI.
