摘要： A control device for a multi-cylinder internal combustion engine that is equipped with a variable compression ratio mechanism includes an air-fuel ratio sensor, and a controller that determines whether or not actual mechanical compression ratios in cylinders of the internal combustion engine are uniform. The controller controls the variable compression ratio mechanism by decreasing a target mechanical compression ratio from a current first target mechanical compression ratio to a second target mechanical compression ratio without changing the amount of intake air and a fuel injection amount, and determines that the actual mechanical compression ratios in the cylinders are not uniform when the target mechanical compression ratio is set at the first target mechanical compression ratio if the differences in the output air-fuel ratios from the air-fuel ratio sensor for exhaust gases from the cylinders before and after the control of the variable compression ratio mechanism are not uniform.

摘要： A control device for an internal combustion engine. An object of the present invention is to provide a control device for an international combustion engine for highly accurate absolute pressure correction irrespective of the length of an adiabatic compression stroke period. When the number of cylinders in an engine is n (n is an integer of 2 or more), an adiabatic compression stroke period of one cylinder preceding another cylinder to be corrected into its absolute pressure by a 1/n cycle (ignition timing —IVC) is compared with a threshold CATH (step 100). In the step 100, the absolute pressure correction is carried out based on PVκ=constant when the adiabatic compression stroke period is longer than the threshold CATH (step 110). On the other hand, the absolute pressure correction is carried out based on a value PIP detected by an intake pipe pressure sensor when the adiabatic compression stroke period is shorter than the threshold CATH.

摘要： An internal combustion engine which is provided with a variable compression ratio mechanism which can change a mechanical compression ratio and a variable valve timing mechanism which can control a closing timing of an intake valve. No-entry regions (X1, X2) are set for a combination of the mechanical compression ratio, the closing timing of the intake valve, and the intake air amount. Furthermore, a no-entry layer is set so as to surround the no-entry region (X2). When the demanded intake air amount is made to decrease and the operating point moves toward the no-entry region (X2), the operating point is prohibited from entering the no-entry layer whereby the operating point is blocked from entering the no-entry region (X2).

摘要： Disclosed is a control device, which controls an air-fuel ratio sensor that is mounted in an exhaust path of an internal-combustion engine. The air-fuel ratio sensor is capable of pumping oxygen in a gas. Normally (time t0-t1, time t3 or later), a positive voltage Vp1 is applied to a sensor element (FIG. 7A), and the air-fuel ratio is calculated (FIG. 7C) in accordance with a sensor current (FIG. 7B). A heater is driven after internal-combustion engine startup to heat the sensor element. In a process in which the sensor element temperature rises, a negative voltage Vm, which is oriented in a direction different from that of the positive voltage Vp1, is applied to the sensor element.

摘要： With the use of a model expression (FIG. 9C), of which inputs include a desired value of an in-cylinder air amount that is a controlled object of a system and predetermined parameters, such as engine speed (ne), a desired throttle opening degree (θref) required to control the in-cylinder air amount to the desired value is calculated. In this model expression, parameters, such as the engine speed (ne), that oscillate at a relatively high frequency are excluded from subjects of differentiation, and the desired in-cylinder air amount value only is included in the subjects of differentiation.
