The apparatus for calculating the work done by an engine establishes in advance correlation of phase between the cylinder internal pressure of the engine and a reference signal composed of a predetermined frequency component as a reference phase relation. A means for detecting the cylinder internal pressure of the engine for a predetermined observation section is provided.

The method calculates the work amount parameter Pmi indicative of the amount of work done by the engine 3 including a combustion chamber 3b, as follows: Pressure in the combustion chamber 3b is detected to obtain in-cylinder pressure data P indicative of the detected pressure. Volume data V indicative of a state of change in volume of the combustion chamber 3b is obtained. The obtained volume data V is subjected to a first predetermined filtering process. The work amount parameter Pmi is calculated based on the detected in-cylinder pressure data P, and the volume data filtered value VF obtained by subjecting the volume data V to the first filtering process.

摘要： A failure detection apparatus for preventing erroneous detection due to a degradation of a sensor and thereby accurately performing failure detection of a variable valve timing and lift control system is provided. The detection apparatus detects a failure of a variable valve timing and lift control system in an engine. The detection apparatus detects a vibration inside an engine cylinder, extracts the component of seating sound of the valve from the output signal of the sensor, determines an actual seating time of said valve from the component of seating sound, and calculates a target seating time of said valve based on at least one of a requested lift amount, a requested advance angle, and a requested open angle depending on the operating conditions. The detecting apparatus corrects the actual seating time for a stationary deviation between the actual seating time and the target seating time caused by degradation or unevenness of the sensor. The detecting apparatus determines a failure of the variable valve timing and lift control system by comparing the corrected actual seating time with the target seating time.

摘要： An ignition timing control system for internal combustion engines, which is capable of preventing occurrence of variation in engine speed and vibrations which can be caused due to variation in combustion state between the cylinders, to thereby improve drivability. The ECU 2 of the ignition timing control system 1 calculates a statistically processed value Pmi_ls#i according to the in-cylinder pressure Pcyl#i, and calculates an averaging target value Piav_cmd by weighted averaging of a minimum value Pmi_ls_min1 and a second minimum value Pmi_ls_min2 within a predetermined range of the statistically processed value. The ECU 2 calculates a correction value DIGCMP#i by performing a limiting process for setting the optimization correction value DIGOP#i for control of the ignition timing to a limit value on the advanced side, on the averaging correction value DIGPIAV#i for causing the statistically processed values Pmi_ls#i to follow the averaging target value Piav_cmd, such that the statistically processed values Pmi_ls#i becomes maximum. The ignition timing IGLOG#i is calculated for each cylinder based on the correction value DIGCMP#i.
