A hybrid system which can calculate various type of more proper required torques is provided while input factors which can be used for calculating the various types of required torques are limited. A hybrid systemincludes a rotation sensorwhich detects a rotation number of an engine, at least either one of an accelerator opening-degree sensorwhich detects an accelerator opening degree and a rotation-number instruction unitwhich transmits a rotation-number signal instructing a certain rotation number to the engine, and a control unitwhich controls an operation of the engine. The control unitexecutes control of calculating a torque determining factor for determining a system required torque as the hybrid systemon the basis of at least either one of the accelerator opening degree detected by the accelerator opening-degree sensorand the rotation-number signal transmitted by the rotation-number instruction unitand control of calculating the system required torque on the basis of the rotation number detected by the rotation sensorand the calculated torque determining factor.

Hybrid system

There is provided a fluid heating device for an engine with increased heating efficiency of fluid. The fluid heating device for an engine includes: a holder; a heater; and a radiator pipe, the radiator pipe is inserted into the holder, the heater is housed in the holder, heat of the heater is radiated to fluid passing through the radiator pipe via the radiator pipe. The radiator pipe is formed by an outer pipe and an inner pipe in the outer pipe, the heat generated by the heater is transferred to the outer pipe and the inner pipe, the fluid passing inside and outside the inner pipe in the outer pipe is heated by heat radiation from the outer pipe and the inner pipe.

Fluid heating device for engine

A fluid heating device of an engine is provided that is capable of reducing power consumption of a heat source required for heating a fluid. The fluid heating device of the engine includes a heat radiation pipe through which a fluid passes and an induction heating coil. Heat of the heat radiation pipe that is inductively heated by the induction heating coil is radiated to the fluid. A whole periphery of the heat radiation pipe is surrounded by the induction heating coil. The induction heating coil is supported by the heat radiation pipe. A holder is included, and the induction heating coil is supported by the heat radiation pipe via the holder. The holder, to which the induction heating coil is attached, is detachably supported by the heat radiation pipe.

The disclosed exhaust treatment device for a diesel engine can prevent heat damage to a DPF when regenerating said DPF. If a selection device (), which selects whether to allow or prohibit an automatic DPF regeneration process, is set to prohibit the automatic DPF regeneration process, a DPF regeneration control device () is made able to start a process to cancel execution of the automatic DPF regeneration process. If the selection device () is set to allow the automatic DPF regeneration process, the DPF regeneration control device () retracts the cancellation of the automatic DPF regeneration process, allowing execution of the previously-cancelled automatic DPF regeneration process to begin.

Exhaust treatment device for a diesel engine

Provided is an exhaust-treatment device for a diesel engine, said device being capable of suppressing engine noise. In a first stage Pof an exhaust-temperature-raising process, a target engine speed is set to a prescribed first target speed Rand an intake throttle valveis set to a prescribed first degree of opening O. In a second stage P, the target engine speed is maintained at the first target speed Rand the intake throttle valveis set to a position more closed than the first degree of opening O. When a set duration Tfor the second stage Phas come to an end, the intake throttle valveis at a second degree of opening O, which is maintained in third and subsequent stages P/P. In said third and subsequent stages P/P, as a set duration T/Tfor each stage P/Ppasses, the target engine speed is updated to a target speed R/Rhigher than the target speed R/Rduring the immediately prior stage P/P, and the temperature of DPFupstream exhaust gasis increased.

An object of the present invention is to provide the exhaust treatment device of a diesel engine which is capable of prohibiting the execution of DPF regenerating processing in a situation in which the DPF regenerating processing is inappropriate. In order to achieve the object, DPF regenerating mode switch manipulation means () switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode () or an acceleration-sole regenerating mode (), and DPF regenerating selection manipulation means () switches a position to a normal regenerating permission position (), a normal regenerating cancel position (), or an acceleration regenerating execution position (). When the DPF regenerating mode is in the acceleration-sole regenerating mode (), the DPF regenerating control means prohibits normal regenerating processing by the DPF regenerating means irrespective of a position selected by the DPF regenerating selection manipulation means ().

A method and apparatus for use with an automatic working vehicle for detecting a boundary between a treated area and an untreated area. A predetermined range of working area including the treated area and the untreated area is photographed by a camera. Image data output from the camera is differentiated with respect to pixel to pixel brightness variations, which is then compared with a threshold value to produce edge image data on an X-Y plane showing, as binarized, a plurality of pixels regarded as representing a point of transition between the untreated area and the treated area, and other pixels. The boundary is calculated from the edge image data by means of HOUGH-transformation.
