摘要： Heat generation amount PVκ(θ) is calculated with the use of cylinder pressure P(θ), detected by a cylinder pressure sensor, cylinder volume V(θ), and specific heat ratio κ (steps 100 to 102). A crank angle θfix, at which the value of PVκ(θ) peaks, is determined as a start crank angle, at which an adiabatic process after combustion starts (step 104). A correction coefficient Kfix is calculated based on the variation of the value of PVκ(θ) after θfix (step 106). An actual heat generation amount PVκfix(θ) is calculated with the use of the correction coefficient Kfix (step 110). A cooling loss coefficient Kcool that determines a correlation between the cooling loss and crank angles may be calculated based on a water temperature and an engine speed and the actual heat generation amount PVκfix(θ) may be made to reflect the cooling loss coefficient Kcool.

For convenience' sake, a “crank angle at which dPVκ/dθ is a maximum while PVκ is increasing” is to mean a “crank angle at a combustion proportion of 50%” and be referred to also as “θCA50”. PVκ calculated for θCA50 is to be referred to also as “PVκCA50”. In addition, for convenience' sake, a difference between PVκ (which is zero in the embodiment as shown in FIGS. 3 and 4) and PVκCA50 at a start of combustion is also referred to as ΔPVκCA50.

摘要： An object of this invention is to accurately detect a sensitivity abnormality of an in-cylinder pressure sensor over a wide operating range without using other sensor outputs or the like. Based on only the output of an in-cylinder pressure sensor 44, an ECU 50 acquires a first parameter that is affected by an output sensitivity of the sensor, and a second parameter that is not affected by the output sensitivity. Specifically, the ECU 50 acquires a heat release quantity PVκ as the first parameter, and acquires an indicated torque ratio (A2/A1) as a second parameter. The ECU 50 also calculates a determination coefficient α that is a ratio between the first and second parameters, and determines that the output sensitivity of the in-cylinder pressure sensor 44 is abnormal when the determination coefficient α deviates from an allowable range. Thus, even without utilizing another sensor output or the like in an auxiliary manner or previously preparing a large amount of data or the like, a sensitivity abnormality of the in-cylinder pressure sensor 44 can be easily detected over a wide operating range.

摘要： In a control apparatus, when an engine is cranked, “an air-fuel mixture (an air-fuel mixture used for determination of fuel property) including fuel in a first predetermined fuel amount TAUm and air in a first predetermined air amount Mcm”, which generates torque that does not make the engine autonomously operate, is formed in a first cylinder (cylinder used for determination of the fuel property), and the air-fuel mixture is ignited and combusted by a spark at an ignition timing after a compression top dead center. Further, the control apparatus determines “an amount of heat generated per unit mass of the fuel” when the air-fuel mixture is combusted in the first cylinder, and determines a property of the fuel based on the amount of generated heat.

摘要： The internal combustion engine has a valve driving mechanism (VM) capable of changing the valve-opening characteristic of at least one of an intake valve (Vi) and an exhaust valve (Ve), an in-cylinder pressure sensor for detecting the in-cylinder pressure in a combustion chamber and ECU. ECU calculates the variation amount of the in-cylinder pressure caused by the valve-overlap of the intake valve (Vi) and the exhaust valve (Ve), and based on this variation amount of the in-cylinder pressure and the in-cylinder pressure detected at a predetermined timing in the compression stroke, calculates an amount of air sucked in the combustion chamber, as well as, based on this calculated intake air amount, determines the ignition timing. The amount of air sucked in the combustion chamber is accurately and costlessly calculated, and the ignition timing is optimally determined by using the calculated air amount.

摘要： The present invention makes it possible to accurately determine an EGR rate from an in-cylinder pressure. An EGR rate determination method for an internal combustion engine according to the present invention, a combustion period is calculated by using in-cylinder pressure data measured by an in-cylinder pressure sensor. An in-cylinder flame velocity is then calculated from the combustion period. Next, in accordance with prepared data indicative of the influence of an engine speed on the flame velocity, a portion of the flame velocity calculated from the combustion period that is affected by the engine speed is eliminated. Eventually, a current EGR rate is determined from the flame velocity from which the portion affected by the engine speed is eliminated.
