摘要： In an exhaust cleaning system including a DPF in exhaust passages, a pair of temperature sensors is disposed upstream and downstream the filter to detect upstream and downstream exhaust temperatures. An electronic control unit estimates a downstream exhaust temperature from the actual upstream exhaust temperature when an engine is in a predetermined condition such as a cold-start condition or a high speed and high load condition, in which no catalytic reaction heat is generated in the DPF. The control unit then compares the estimated downstream temperature with the actually detected downstream temperature, and determines an exhaust temperature senor malfunction if the difference between the compared temperatures are large.

摘要： A compression ignition engine injects fuel through injection holes of an injector at a substantially constant injection rate to atomize the fuel so that the fuel can be easily vaporized and to make the fuel penetrate an atmosphere inside a cylinder. A spatial distribution of the injected fuel in which mixing of the fuel and air is promoted as the fuel recedes from the injection hole and the fuel reaches a premixing space where the fuel is premixed with the air is provided. The engine controls oxygen concentration inside the cylinder and an ignition delay so that a ratio of a quantity of the fuel injected before a start of ignition to a total fuel injection quantity falls within a range from 25% to 50% and so that the premixed gas formed in the premixing space is combusted serially.

摘要： A diagnostic device of an internal combustion engine diagnoses a condition of a differential pressure sensor. The sensor in a normal condition detects a differential pressure of an exhaust gas between upstream and downstream sides of a diesel particulate filter disposed in an exhaust system of the engine. The sensor in a fault condition detects no differential pressure of the exhaust gas. The device has a block obtaining a first signal from the sensor when the engine is operated in a low flow rate region of the exhaust gas and obtaining a second signal from the sensor when the engine is operated in a high flow rate region of the exhaust gas. A diagnostic block of the device judges from a difference between levels of the first and second signals whether the sensor is in the normal or fault condition.

摘要： An exhaust gas cleaning apparatus (e.g., for a diesel engine) uses a collector for collecting particulates contained in the exhaust gas and is disposed in an exhaust pipe of the engine. Damages in the collector are detected based on a pressure difference between an inlet and an outlet of the collector. In order to correctly detect the damages based on the pressure difference, an exhaust gas volume flowing through the collector is increased to a target volume by raising exhaust gas temperature. The exhaust gas temperature is raised by injecting fuel into the engine at a time when an engine output is not increased by such fuel injection. The pressure difference, based on which damages in the collector are detected, is measured after the exhaust gas volume has reached the target volume. It is determined that damages in the collector have occurred if the pressure difference is lower than a predetermined value.

摘要： Unless an abnormality exists in piping introducing a pressure from front and rear of DPF 22 into a differential pressure sensor 45, pulsations of pressure propagation through an exhaust passage 21 is offset in a detection value of a pressure difference of the differential pressure sensor 45, and an amplitude of the detection value of the DPF pressure difference resulting from pulsation of the pressure becomes small. If a crack exists in one of the piping 3a and 3b, the influence of a pulsation of the pressure appears in the DPF pressure difference and the amplitude of the detection value of the DPF pressure difference becomes large. The amplitude of the detection value of the DPF pressure difference is compared with the reference value and is detected as being abnormal when it is large, utilizing the phenomenon described above.

摘要： An exhaust gas purifying apparatus for an internal combustion engine includes a collector, which collects exhaust particles in exhaust gas. The apparatus computes a pressure-difference-based measured value of a collected amount of the particles based on a pressure difference, and computes a pressure-difference-based estimated value by correcting the measured value. The apparatus computes an operational-state-based estimated value of the collected amount. The apparatus regenerates the collector by burning the exhaust particles when one of the pressure-difference-based estimated value and the operational-state-based estimated value reaches a predetermined value. The apparatus computes a current pressure-difference-based estimated value by correcting a current pressure-difference-based measured value based on information related to an immediately preceding operational-state-based computing period such that the current pressure-difference-based estimated value ranges from the current measured value to a previous pressure-difference-based estimated value.
