摘要： PROBLEM TO BE SOLVED: To accurately determine a regenerating timing for a particulate filter (DPF). SOLUTION: In the computation of a PM amount executed by an ECU 51, accumulation property which specifies increase property for pressure loss to increase with the PM accumulated amount in DPF 32 is represented by a front stage property line ranging from an initial point where an inclination is gentile beyond a transition point to the transition point and a rear stage property line ranging from the transition point. The accumulated amount is calculated from the pressure loss in accordance with the accumulation property. When the accumulated amount gets to a regeneration required value, regeneration is executed. When an accumulated condition in the particulate filter is changed with the combustion of exhaust gas particulates and the accumulation property appears which tracks back an accumulated amount decaying property line from a point on the rear stage property line through the initial point toward a surface layer portion accumulation property line represented by a straight line having the same inclination as the rear stage property line, during a time before transition to the surface layer portion accumulation property line is completed, the regeneration required value is made smaller with the accumulated exhaust gas particulates being in a combustion condition, avoiding too much delay of a regeneration timing.

摘要： PROBLEM TO BE SOLVED: To provide atomization of fuel and penetration of spray in a fuel injection nozzle.
SOLUTION: A group injection hole 6 is adopted to the fuel injection nozzle, injection hole diameter of the injection hole 7 is defined as D, crossing distance from an outlet of the injection hole 7 to a crossing point of a center axis of each injection hole 7 is defined as X and crossing angle of the center axis of each injection hole is defined as θ.

摘要： PROBLEM TO BE SOLVED: To provide an engine of a compression and ignition type having improved noise and fuel consumption while reducing exhaust emission. SOLUTION: Fuel is injected from a nozzle of an injector 11 at an almost constant injection rate in an atomized and easily evaporated form and passed through a cylinder atmosphere. The space distribution of the injected fuel is formed where fuel and air are mixed more as located farther from the nozzle to the direction of injection and a premixture region exists with the fuel premixed and evaporated. The concentration of oxygen in the cylinder of the internal combustion engine and the time length of an ignition delay are controlled so that the rate of a preignition injection amount before starting ignition to the total injection amount at one fuel injection is 25-50% and combustion occurs in the formed premixture region in sequence. Thus, gradual premixture combustion is achieved. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To enhance reliability of a common rail type fuel injection system by forcefully valve-opening a pressure limiter when a suction control valve (SCV) is unable to control. SOLUTION: In the common rail type fuel injection system, it delays with respect to angle actual injection timing of an injector and injection timing of a cylinder overlapping periods of actual injection and pressure feed of a supply pump until the pressure feed period of the supply pump is completed, for example, up to vicinity of ATDC20° of crank angle (CA) when regulated valve opening reaches impossible region (NG region) in the case of the common rail type fuel injection system with 2 injection 1 pressure feed between 360°CA. Consequently, it is configured such obstacle at rising time that common rail pressure (PC) exceeds setting value of valve opening pressure of the pressure limiter. The pressure limiter is forcefully valve-opened by prompting rise in the common rail pressure (PC) without attempting to perform the fuel injection from the injector into the cylinder in the engine.

摘要： PROBLEM TO BE SOLVED: To correct variation in quantity of fuel actually injected to a pilot injection quantity (QPILOT) due to variation of injection quantity of individual injectors of the respective cylinders of a multi-cylinder engine and a change with the passage of time.
SOLUTION: The rotational frequency difference between the instantaneous maximum rotational frequency in multi-injection without after injection to perform pilot injection and the instantaneous maximum rotational frequency in multi-injection with after injection for adding after injection is compared with the target rotational frequency difference (target ΔNE). The after injection quantity (QAFTER) is increased or decreased so that the rotational frequency difference (ΔNE) substantially conforms to the target ΔNE. Subsequently, a learning correction pulse duration (ΔTQAFTER) increased and decreased according to the target ΔNE is reflected in a learning value (ΔTQPILOT) of a pilot injection command pulse duration (TQPILOT) set according to the pilot injection quantity, thereby correcting TQ-Q map previously stored in a memory.

摘要： PROBLEM TO BE SOLVED: To provide a NOx sensor abnormality detecting device for detecting abnormality of a NOx sensor with high accuracy, and an exhaust gas purification system using the same. SOLUTION: When an engine is in a steady operaton state (S300:Yes), a zero point of an NOx concentration is sensed, and an O 2 sensing section of the NOx sensor is normal (S302:Yes), the NOx sensor abnormality detecting device senses the NOx concentration and O 2 concentration from an output signal from the NOx sensor (S304), and then calculates an estimated NOx concentration from the O 2 concentration (S306). The NOx sensor abnormality detecting device calculates a sensed inclination and an estimated inclination of NOx concentration output characteristics of the NOx sensor based on the NOx concentration and O 2 concentration sensed at S304 and the estimated NOx concentration calculated from the O 2 concentration at S306. When an absolute value of a difference between the sensed inclination and the estimated slope is greater than a predetermined value (S310:Yes), the NOx sensor abnormality detecting device determines that the NOx sensor is faulty (S312).

The number of groups can be increased by preventing increase of black smoke to achieve high output of the engine by setting the distance C between groups to 0.8 times or more the distance α between injection holes in a group.
