摘要： A combustion chamber structure for a direct injection diesel engine is provided which can increase recirculated amount of exhaust gas while avoiding generation of black smoke and deterioration of fuel efficiency as much as possible.Disclosed is a combustion chamber structure for a direct injection diesel engine having a cavity 10 on a top surface of a piston 9. The cavity is concave to provide a majority of the combustion chamber. Fuel is injected from a center of a cylinder top radially into an inner periphery of the cavity 10 to self-ignite. A depression 24 is formed at an outer periphery of the cavity 10 and is sunken relative to the top surface of the piston 9 to provide a step. The depression 24 has a bottom with an outer periphery gradually rising radially outwardly in modestly curved surface to the top surface of the piston 9. The inlet lip 11 is formed at a position lower than the top surface of the piston 9 by an inner periphery of the bottom of the depression 24 and a combustion chamber wall 12 rising from a bottom of the cavity 10.

摘要： A turbocharger (2) mounted on an engine (1) has an EGR pipe (11) through which part of exhaust gas (8) is extracted from an exhaust manifold (9) to be recirculated to a suction pipe (4), the exhaust manifold (9) being internally divided by a partition (14) for prevention of exhaust interference between cylinders (7). A turbine scroll (15) is internally divided, for continuity with an outlet flow path of the exhaust manifold (9), by a partition (16) such that one of the divided flow paths (A, B) by the partition (16) which served for extraction of the exhaust gas (8) to be recirculated is smaller in cross-sectional area than the other flow path which does not serve for extraction of the exhaust gas (8) to be recirculated.

摘要： Fuel is added to exhaust gas 9 upstream of a catalytic regeneration type particulate filter 13 in an exhaust pipe 11. The fuel added is oxidized on a flow-through type oxidization catalyst 14 before the particulate filter 13 to generate exothermic heat with which captured and accumulated particulates in the particulate filter 13 are burned off to forcibly regenerate the particulate filter 13. When the driving is being performed in light-load engine operation areas upon forcible regeneration of the particulate filter 13, a retarder 22 is activated, with an accelerator pedal retaining its on-state, and an amount of fuel injected is increased to compensate reduction of torque due to such activation of the retarder 22.

摘要： A sub-rate time switch switches a digital multiplexed signal having a basic-rate signal included in a first time slot of the digital multiplexed signal and N sub-rate signals included in a second time slot thereof where N is an integer. Each the sub-rate signals has a sub-rate which is equal to 1/N times a basic rate of the basic rate signal. A speech path memory temporarily stores the digital multiplexed signal input to the sub-rate time switch. A channel signal is read out from the speech path memory and has a plurality of channels corresponding to time slots of the digital multiplexed signal. A control part controls write and read operations of the speech path memory so that the channel signal includes N consecutive channels. Each of the N consecutive channels includes N identical sub-rate signals, and each of the N identical sub-rate signals corresponds to one of the N sub-rate signals included in the second time slot of the digital multiplexed signal.

摘要： A diesel engine comprising a fuel injection device and a controller for controlling the fuel injection device in accordance with an operating condition of the engine. The fuel injection device effects a preliminary injection for injecting fuel into a cylinder during a period from the initial part of an intake stroke to the middle part of a compression stroke and a main injection for injecting fuel into a combustion chamber in the vicinity of a top dead center of the compression stroke, whereby lean mixture is formed and a maximum combustion temperature in the combustion chamber is decreased to suppress generation of NOx and to reduce emission of black smoke.
