Abstract

A method for reducing the exhaust pollution emissions in a sliding vane internal combustion engine. First, an ultra-lean fuel-air combination is thoroughly premixed, the fuel-air combination having an equivalence ratio less than about 0.60 and a dimensionless concentration fluctuation fraction below about 0.33. After being premixed, the ultra-lean fuel-air combination is inducted into a vane cell, compressed, and it is then combusted at a peak compression plateau. The combusted fuel-air combination is purged after an expansion cycle. The combusting of the fuel-air combination may be initiated by autoignition.
