Abstract
An apparatus for detecting a condition of the burning in an internal combustion engine includes a burning-parameter controlling device for controlling a burning parameter operating on the burning in the internal combustion engine. A burning-condition detecting device operates for, in cases where the burning parameter is changed by the burning-parameter controlling device, sampling prescribed information for detecting a burning condition.
Claims12
An apparatus for detecting a condition of the burning in an internal combustion engine, comprising:
- burning-parameter controlling means for controlling a burning parameter operating on the burning in the internal combustion engine;
- and
- burning-condition detecting means for, in cases where the burning parameter is changed by the burning-parameter controlling means, sampling prescribed information for detecting a burning condition.
An apparatus for detecting a condition of the burning in an internal combustion engine in which a spark timing is variable, the apparatus comprising:
- first means for detecting a timing of a latest spark in the engine;
- second means for detecting a rotational speed of the engine at a timing which depends on the latest-spark timing detected by the first means;
- and
- third means for detecting a condition of the burning in the engine in response to the rotational speed detected by the second means.
An apparatus for detecting a condition of the burning in an internal combustion engine in which a spark timing is variable, the apparatus comprising:
- first means for detecting a timing of every spark in the engine;
- second means for detecting a rotational speed of the engine at a timing depending on the timing of every spark which is detected by the first means;
- third means for inhibiting the second means from detecting a rotational speed of the engine twice or more with respect to the timing of every spark which is detected by the first means;
- and
- fourth means for detecting a condition of the burning in the engine in response to the rotational speed detected by the second means.
