Abstract
There is provided a control system for an internal combustion engine. An amount of variation in the rotational speed of the engine is detected. A rotational speed variation reference value is calculated based on an averaged value of the detected amount of variation in the rotational speed of the engine. The detected amount of variation in the rotational speed of the engine is compared with the rotational speed variation reference value. The amount of fuel to be supplied to the engine is corrected based on results of the comparison.
Claims14
A control system for an internal combustion engine, comprising:
- fuel supply amount-calculating means for calculating an amount of fuel to be supplied to said engine;
- rotational speed variation-detecting means for detecting an amount of variation in rotational speed of said engine;
- averaging means for averaging said amount of variation in said rotational speed of said engine detected by said rotational speed variation-detecting means;
- rotational speed variation reference value-calculating means for calculating a rotational speed variation reference value based on an average value of said amount of variation from said averaging means;
- comparison means for comparing said detected amount of variation in said rotational speed of said engine with said rotational speed variation reference value;
- and
- correction means for correcting said amount of fuel to be supplied to said engine, calculated by said fuel supply amount-calculating means, based on results of said comparison by said comparison means.
A control system for an internal combustion engine installed on an automotive vehicle, comprising:
- operating condition-detecting means for detecting operating conditions of at least one of said engine and said automotive vehicle;
- fuel supply amount-calculating means for calculating an amount of fuel to be supplied to said engine;
- combustion state-detecting means for detecting a parameter indicative of a combustion state of said engine;
- first combustion state reference value-calculating means for calculating a first combustion state reference value based on said parameter indicative of said combustion state of said engine detected by said combustion state-detecting means;
- second combustion state reference value-calculating means for calculating a second combustion state reference value depending on said operating conditions of said at least one of said engine and said automotive vehicle detected by said operating condition-detecting means;
- comparison means for comparing said detected parameter indicative of said combustion state of said engine with said first combustion state reference value and said second combustion state reference value;
- and
- correction means for correcting said amount of fuel to be supplied to said engine calculated by said fuel supply amount-calculating means, based on results of said comparison by said comparison means.
