Abstract:
A method is disclosed for controlling exhaust emissions from direct injected homogeneous charge compression ignition engines by combusting therein a fuel having a cetane number equal to or less than 50, and aromatic content equal to or greater than 15wt%.
Abstract:
A fuel composition for a homogenous charge compression ignition engine includes a combination of a gasoline fuel and a diesel fuel, the combination having a derived cetane number of from about 19.9 to 45 as determined in accordance with ASTM method D6890. A method for making the fuel composition provides for blending presently available gasoline fuel and diesel fuel together in a ratio to obtain the desired fuel composition.
