摘要： PROBLEM TO BE SOLVED: To suppress increase of back pressure in exhaust passages to the utmost at the time of occlusion and reduction of NOx occluded in NOx catalysts and to improve mountability to a vehicle, in an internal combustion engine having the plurality of NOx catalysts arranged in parallel on the exhaust passages. SOLUTION: This exhaust emission control system for the internal combustion engine has the two exhaust passages 3L, 3R connected with each of two divided cylinder groups 2L, 2R sharing exhaust gas. The three NOx catalysts 14, 15, 16 are provided in parallel on the exhaust passages 3L, 3R. Each of the two exhaust passages 3L, 3R is branched and connected with the three NOx catalysts 14, 15, 16, such that exhaust gas can be branched and flowed into the two exhaust passages 3L, 3R. When NOx occlusion amount of one of the NOx catalysts 14, 15, 16 is below predetermined NOx occlusion amount, exhaust gas is flowed into the three occlusion/reduction type NOx catalysts 14, 15, 16 from the two exhaust passages 3L, 3R. When NOx occlusion amount of the one of the NOx catalysts 14, 15, 16 exceeds the predetermined NOx occlusion amount, fuel is supplied while an exhaust gas flow rate flowed into the one NOx catalyst is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a technique for highly accurately measuring a cetane number of fuel, while the fuel is used for operating an internal combustion engine. SOLUTION: Pressure P in a combustion chamber is detected by a pressure detecting means, and volume V of the combustion chamber is detected by a volume detecting means. When a value near a ratio of specific heat of air-fuel mixture is a constant κ, a product PV κ is calculated as a heat generation parameter, by multiplying the pressure P by a value obtained by getting the volume V raised to the κth power. In a rated operational state of the internal combustion engine, the cetane number of the fuel is measured based on variation in the heat generation parameter PV κ after the fuel is injected into the combustion chamber.

摘要： PROBLEM TO BE SOLVED: To suppress the change of a driving force by adjusting the driving force to a desired value and by absorbing the change of engine torque, even if change occurs in the engine torque. SOLUTION: This motor generator control method is for a parallel hybrid vehicle provided with an engine that has a cylinder internal pressure sensor and a motor generator that assists power generation by an engine output or the engine output by battery electric power. Based on the detected opening of an accelerator, engine revolutions, and preset demanded torque map, driver-demanding torque is calculated (Steps S10, S11). Using the output value of the cylinder internal pressure sensor, the change of the cylinder internal pressure is detected (Step S12). Based on this detected cylinder internal pressure, the predicted amount of change of the engine torque or the predicted amount of change of the driving force is calculated (Steps S13, S14, S15). According to the predicted amount of change of the engine torque, the assist amount or the regeneration amount of the motor generator is feedback-controlled (Step S16). COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To eliminate the influence of combustion chamber pressure, in a device controlling fuel injection based on the combustion chamber pressure detected by a combustion chamber pressure detection means.
SOLUTION: An ECU 20 acquires the combustion chamber pressure P with respect to a crank angle by amplifying output E from cylinder pressure sensors 29a to 29d with an amplifier 31, calculates a PVmax and a PVbase from the combustion chamber pressure P, and then calculates an actual PV ratio = (PVmax/PVbase)-1. Further, the ECU stores a standard PV ratio of a standard engine under the same operating conditions, and corrects a fuel injection amount so that the actual PV ratio becomes equal to the standard PV ratio. The ECU calculates a corrected PV difference value = a corrected PVmax-a corrected PVbase from the corrected PVmax and the corrected PVbase, acquires a ratio α = a corrected PV difference value/a standard PV difference value that is the ratio between the corrected PV difference value and the stored standard PV difference value of the standard engine, and corrects an amplification factor G by multiplying the amplification factor G of the amplifier by 1/α.
