To provide a method for controlling exhaust emissions from a direct injection homogeneous charge compression ignition engine.
The method includes combusting a fuel having: a cetane number or derived cetane number as determined by ASTM D613 or ASTM D6890, respectively, of between ≥38.5 to ≤50; a total aromatic compounds content of between ≥28.7 to ≤44.7 wt.% ; and 90% distillation temperatures as determined by ASTM D86 of between ≥314°C to ≤329°C, and setting fuel injection timing to the engine to before top dead center, in the direct injection homogeneous charge compression ignition engine in which the fuel is injected during the compression stroke. As a result, the method allows the direct injected homogeneous charge compression ignition engine to operate while controlling the exhaust emissions, and allows NOx exhaust discharge to be ≤20 ppm.
