摘要： A method of operating an internal combustion engine includes moving an exhaust valve to a first open position to enable an exhaust product to flow through an exhaust port of the internal combustion engine. The method also includes maintaining the exhaust valve at the first open position for a predetermined time period. The method also includes moving an intake valve to a second open position during the predetermined time period to enable an intake product to flow through an intake port of the internal combustion engine. Additionally, the method includes preventing at least a portion of the intake product from flowing through the exhaust port during the predetermined time period with a first blocking member and a second blocking member.

摘要： A method for predicting and correcting an impending misfire in a homogeneous charge compression ignition (HCCI) engine includes: modeling HCCI engine operation in a nominal, steady-state operating region and in unstable operating regions bordering the steady-state operating region, using a zero-dimensional model; predicting an occurrence of an engine misfire based on the modeling of the HCCI engine operation; and providing a remedial corrective measure when an engine misfire is predicted. The remedial corrective measure includes one of: (a) late injection to avoid full combustion during a trapping cycle, and a reduction in amount of injected fuel to account for residual fuel of the previous cycle; or (b) earlier exhaust valve closing to trigger combustion of residual fuel within the trapping cycle, and a later injection and reduction of injected fuel to account for residual fuel of the previous cycle.
