    摘要: A method of and apparatus for reducing smoke emitted from a diesel engine are disclosed. The apparatus comprises: a trap for trapping black smoke particles which is disposed within the exhaust system of the engine, the trap including a ceramic trap assembly having a honeycomb structure in which a catalyst which enables lowering of the combustion temperature of black smoke is carried on internal passage walls; a pressure sensor provided at the inlet of the trap; an engine speed sensor; a butterfly valve provided in the intake system of the engine; and a combination of a controller and an actuator for the butterfly valve. In this apparatus and method the controller obtains a specified exhaust pressure range in the trap on the basis of a signal from the engine speed sensor, compares an exhaust pressure signal from the pressure sensor with the specified exhaust pressure range, and controls the actuator so that the actuator controls the degree of opening of the butterfly valve so that the exhaust pressure inside the trap is maintained within the specified exhaust pressure range. By this means, black smoke particles can be controllably burned by means of exhaust gas without causing any engine trouble. Since the trap can be regenerated with the ceramic trap assembly left in place in, for example, a construction machine, it is possible to provide a diesel engine smoke reducing apparatus which is superior in both serviceability and durability.

    摘要: This invention provides a system for recording operation data of a machine, wherein a program for converting signals stored through a sensor or measuring means into operation data in conformity with the increase or alteration of the sensor or measuring means due to the operation status of the machine or to the type of the component of the machine is preliminarily stored in one or separate card-type external memory or other transportable external memory. The terminal of the system is designed to allow an connection of various kinds of the sensor or measuring means. Accordingly, it is possible to conduct processing and recording of various kinds of operation data by exchanging the external memory stored with a prescribed operation data-processing program, or by changing the writing of the program. It is also possible to record operation data in the external memory stored with the operation data-processing program after the program is read out to simplify the operation of an operator.

    摘要: A swing control circuit is provided separately from a hydraulic actuator control circuit. The swing control circuit includes a swing pump motor connected to closed circuits of a swing motor through a solenoid valve that serves as a directional control valve. A swing motor generator is connected to the swing pump motor. The swing motor generator is connected to an electric power storage device of a hybrid type drive system. An exterior-connecting passage for feeding hydraulic fluid to hydraulic actuators of a lower structure and a work equipment is drawn from a pipeline between the swing pump motor and the solenoid valve. A connecting passage solenoid valve is disposed in the exterior-connecting passage. The invention enables hydraulic energy generated in the swing system to be directly fed to the outside of the swing system.
