摘要： An internal combustion engine control device for a dual-injection internal combustion engine acquires first and second increase values, which are fuel increase ratios according to respective alcohol concentrations of a fuel injected by cylinder injection (Dl) and a fuel injected by port injection (PFI). The control device determines a basic total injection amount of fuel (TOTAL) that should be supplied to each cylinder in the case where the alcohol concentration of the fuel is zero. An amount of fuel injected from a cylinder injection valve (EO-EQUIVALENT AMOUNT of Dl) is determined as if the alcohol concentration of the fuel were zero. A total injection amount is to correspond to an amount in accordance with the basic total injection amount (TOTAL) and both, the first increase value and the second increase value, so that the increase in injected fuel amount is borne by port injection (PFI).

摘要： A moisture adsorbent (32) for adsorbing moisture in exhaust gas and an NOx adsorbent (34) for adsorbing NOx are disposed in a bypass passage (30) for bypassing an exhaust passage (16) of an internal combustion engine (10). When an adsorption operation to the NOx adsorbent (34) is executed, inflow of the exhaust gas to the bypass passage (30) is allowed until the moisture amount that flows into the water adsorbent (32) reaches an allowable moisture inflow amount. The allowable moisture inflow amount is determined based on a residual moisture amount before the starting of the adsorption operation in the moisture adsorbent (32). The residual moisture amount in the water adsorbent (32) can be determined based on the temperature of the moisture adsorbent (32) at the immediately preceding execution of the purge operation.

摘要： The sulfur oxides detection system 1 comprises: a device part 10 comprising a first electrochemical cell 51 having a first solid electrolyte layer 11, a first electrode 41, and a second electrode 42; and a diffusion regulating layer 16; a power supply 61 supplying voltage between the electrodes; a detector 62 detecting a first current correlation parameter; and a control part 80 controlling the power supply and acquiring the first current correlation parameter. The control part 80 controls the power supply so that a first voltage is applied between the electrodes and calculates a concentration of sulfur oxides in the measured gas based on the first current correlation parameter detected by the detector when the first voltage is applied between the electrodes, but it does not calculate the concentration of sulfur oxides in the measured gas when it judges that a concentration of water in the measured gas is not stable.

摘要： The sulfur oxide detection system (1) comprises; an element part (10) including a sensor cell; a voltage applying part (61); a current detecting part (62); a voltage control part (80b); and an estimating part (80a). The voltage control part (80b) performs first control making the voltage applied to the sensor cell rise so that a voltage of the decomposition start voltage of water and sulfur oxide or more is applied for a first period of time, performs a poisoning recovery control, and performs second control making the voltage applied to the sensor cell rise so that the voltage of the decomposition start voltage or more is applied for a second period of time. The estimating part (80a) estimates a sulfur oxide concentration in the measured gas based on a difference or a ratio of a first current detected when the first control is performed and a second current detected when the second control is performed.

摘要： An object of the present invention is to provide an abnormality detection device that is used for an internal combustion engine whose operation is controlled in accordance with the properties of employed fuel, and capable of accurately detecting an abnormality in a fuel property sensor used to determine the fuel properties, and more particularly, a stuck fuel property sensor. The abnormality detection device is configured so that a measurement section of the fuel property sensor is housed in a fuel container, which is not disposed in a main flow path of a fuel flow path connecting a fuel pump to an injector, but is disposed apart from the main flow path. The fuel drawn from a fuel tank is introduced into the fuel container. The resulting output value of the fuel property sensor is acquired as a first sensor output value. Further, the fuel is discharged from the fuel container. The resulting output value of the fuel property sensor is acquired as a second sensor output value. The first and second sensor output values are then used as the information for abnormality judgment to check for an abnormality in the fuel property sensor.
