摘要： A control apparatus for an engine includes a rotation detector, a fuel injection device, and an output controller. The output controller calculates an emission amount of the pollutant and calculates an accumulated emission amount of a pollutant for a period of time. The output controller calculates a maximum allowable emission amount of the pollutant for a period of time. The output controller calculates a difference between the accumulated emission amount of pollutant and the maximum allowable emission amount of the pollutant. The output controller calculates a first output index by dividing the difference by the period of time. The output controller sets the allowable range for the output of the engine so that the emission amount of pollutant becomes equal to or less than the first output index.

摘要： A method includes operating a spark ignition engine and flowing low pressure exhaust gas recirculation (EGR) from an exhaust to an inlet of the spark ignition engine. The method includes interpreting a parameter affecting an operation of the spark ignition engine, and determining a knock index value in response to the parameter. The method further includes reducing a likelihood of engine knock in response to the knock index value exceeding a knock threshold value.

摘要： An internal combustion engine includes an intercooler configured to cool an intake gas compressed by a compressor, a cooler bypass passage configured to bypass the intercooler, and a cooler bypass valve configured to open and close the cooler bypass passage, and an exhaust gas recirculation gas is introduced into an upstream side of the intercooler. An electronic control unit is configured to open the cooler bypass valve during use of a high exhaust gas recirculation rate region, and to close the cooler bypass valve during use of a low exhaust gas recirculation rate region.
