  • Patent number: 10914264
    Abstract: An engine includes a first injection valve, which is one of port and direct injection valves, and a second injection valve, which is the other. When operating only the first injection valve based on a base injection amount, which has been corrected using a feedback operation amount and a first learning value, an air-fuel ratio control apparatus updates the first learning value and determines that the first learning value has converged on condition that a correction ratio of the base injection amount is not more than a predetermined ratio. When the first and second injection valves are being operated, the apparatus updates a second learning value for the second injection valve on condition that the first learning value has converged and the ratio of the injection amount of the second injection valve is not less than a specified value.

  • Patent number: 10914214
    Abstract: A particle filter for treating exhaust gases includes an SCR catalyst that, when in the presence of a reductant such as ammonia, promotes selective catalytic reduction of NOx; an active oxidation catalyst that promotes oxidation of hydrocarbons and carbon monoxide; and an oxygen storage catalyst that alternately stores and releases oxygen, enhances soot oxidation, and stores NOx at temperatures below optimal SCR functioning. The particle filter may be included in a system having an oxidation catalytic device (OCD) upstream of the particle filter, and optionally includes one or more SCR converters upstream and/or downstream of the particle filter, and/or an ammonia slip catalyst downstream of the particle filter. The system may further be adapted for operation under a high frequency injection fuel control with an OCD having substantial NOx storage material content, or an NSC for improving the efficiency tradeoffs between soot oxidation during filter regeneration and NOx reduction.

  • Patent number: 10900425
    Abstract: Methods and apparatus for conducting engine related diagnostics during cylinder cutoff (DCCO) operation of an engine are described. In one aspect, changes in the amount of oxygen in the exhaust system are monitored while the engine is operating in the DCCO mode. Changes in the oxygen level are then analyzed to determine various faults. Some of the faults that can be detected using this approach include cylinder deactivation faults and exhaust system leak faults. In another aspect, the rate of change of manifold pressure within the air intake manifold is monitored while operating the engine in a DCCO mode with the throttle closed. A fault indicative of potential air leakage into the air intake manifold is indicated when it is determined that the rate of change of the manifold pressure exceeds a designated threshold.
