... in the engine lubricant, accumulates in the DPF. Ash accumulation leads to increased flow restriction and an associated increase in pressure-drop across the particulate filter, negatively impacting engine performance and fuel economy and eventually requiring periodic filter service or replacement. While...

... eventually resulted in misfire. It was found that the latest SOI timing was optimal for fuel economy under this “throttled-intake stoichiometric diesel” operation ( 17 ). Details of the engine operating conditions are listed in Table 2 . The engine speed was 2000 rpm in all of the experiments. Engine...

.... Engine valve timing for optimal efficiency in air regeneration and the corresponding engine speed-torque maps are established using the detailed engine model. The compressed air hybrid engine maps are then incorporated into vehicle simulation ( ADVISOR ) to evaluate the potential fuel economy improvement...
