Abstract: PROBLEM TO BE SOLVED: To provide a NOx removing device which can make an exhaust gas temperature adequate to carry out a NOx reduction, and has a high energy efficiency. SOLUTION: The device comprises an exhaust gas flow path provided with an intake air conduit 10 and an exhaust air conduit 11, a heat conductor 1 comparting the betweenness of the intake air conduit 10 and the exhaust air conduit 11, and carrying out a heat exchange between them, and an oxidation-reduction catalyst containing a NOx reduction catalyst, provided in the exhaust gas flow path. That is, the oxidation-reduction catalyst is arranged in the exhaust gas flow path, and the heat exchange between the exhaust gas warmed by the produced heat and the exhaust gas before reaching the NOx reduction catalyst can minimize successfully a new charge of heat (energy) from outside. Since the heat exchange can control the exhaust gas temperature with the minimum energy charge from outside, it is possible to suppress a vain energy charge, which is useful for both ways of an improvement in fuel consumption and an emission gas purification.

Abstract: PROBLEM TO BE SOLVED: To improve particle matter cohesion performance of an exhaust gas treating device using corona discharge. SOLUTION: In this exhaust gas treating device, by arranging two types of electrodes, a discharge electrode 2 and a dust collecting electrode 4, inside an exhaust pipe of the internal combustion engine and applying high voltage to a space between the electrodes 2, 4 to generate corona discharge, exhaust particles in the exhaust gas are charged and collected. Negative charges carried by the collected exhaust particles are recovered via a coil 5. Since an electric current is suppressed by the action of the coil 5, the exhaust particles in the side opposite to the dust collecting electrode 4 are positively charged. Due to Coulomb force by such charges, cohesion of exhaust particles which have not reached the dust collecting electrode 4 and are negatively charged is promoted. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a pressure pulsation reducing device which can reduce pressure pulsation using a simple configuration and can reduce noise emissions. SOLUTION: A guide part 22 to support a valve member 20 on the body 19 movably in reciprocations is furnished on the side nearer the fuel inlet 19b than the abutting part 20a of a valve member 20. The guide part 22 is furnished with four chamfers 23 so as to form fuel passage in the area to the internal wall of the valve body 19, and sliding parts 24 formed in the circumferential direction alternately with the chamfers 23 make sliding with the valve body 19. The clearance L between the body 19 and sliding part 24 is set to approx. 5 μm, and the damping coefficient of the natural frequency of a spring-mass system formed from the valve member 20 and a compression coil spring 30 is set to 10 Ns/m. Vibrations of the valve member 20 can be damped early using a simple configuration by making the sliding resistance of the sliding part 24 greater than the specified value, and the noise can be reduced by reducing early the pressure pulsation in the low pressure fuel passage.

Abstract: PROBLEM TO BE SOLVED: To provide a control method of an accumulator type fuel supply system for an engine which can perform a first explosion quickly after an engine starts. SOLUTION: A fuel is supplied from a high pressure fuel supply pump 104 to a common rail 105, and the fuel is supplied from the common rail 105 for storing a high pressure fuel to an injector 106. At the time of engine start, a duty control is performed to the high pressure fuel supply pump 104 when a start signal is input, and thereafter the high pressure fuel supply pump 104 is then subjected to a normal operation control when a cylinder discrimination is terminated. The fuel in the injector 106 is infected at plural times per one cycle for a period from an input of an engine starting signal to an input of an engine start termination signal. Accordingly, a pressure in the common rail after engine start is early started up to improve an fuel infection characteristic, resulting in that a startability of the engine is improved.

Abstract: PROBLEM TO BE SOLVED: To reduce a harmful matter discharged into exhaust air and to improve fuel economy. SOLUTION: A second nozzle needle 25 is stored in a hollow and cylindrical first nozzle needle 20. When high pressure fuel in a first pressure control chamber is discharged, the first nozzle needle 20 lifts and high pressure fuel supplied from a common rail is injected from a first nozzle hole 31. When a shim 35 is engaged with an end surface 27a of the second nozzle needle 25 while the first nozzle needle 20 lifts, the second nozzle needle 25 lifts with the first nozzle needle 20, fuel is also injected from a second nozzle hole 32 in addition to the first nozzle hole 31. As the second nozzle needle 25 lifts in accordance with lift of the first nozzle needle 20, it is possible to increase initial injection pressure while reducing an initial injection rate.
