An exhaust gas purification system comprises an exhaust gas purification device which is arranged in an exhaust gas route of an engine, renewing devices for burning and removing a particulate matter within the exhaust gas purification device, renewal advance notifying means which is actuated in the case that a clogged state of the exhaust gas purification device becomes equal to or more than a prescribed level, and renewal informing means which informs of a fact that the renewing devices are under operation. The renewal advance notifying means is actuated before actuating the renewing devices.

Exhaust gas purification system

An exhaust gas purification system is provided with an exhaust gas purification device which is arranged in an exhaust gas route of a common rail type engine, and is structured such that a plurality of renewing modes which burn and remove a particulate matter deposited within the exhaust gas purification device is executed. One of the plurality of renewing modes is an initialization renewing (a forced renewing) mode which supplies a fuel into the exhaust gas purification device by a post injection regardless of a clogged state of the exhaust gas purification device, in the case that an accumulated drive time of the engine becomes equal to or more than a previously set time.

The renewal advance notifying means is actuated before actuating the renewing devices.

Provided is an engine device which improves a general-purpose property of an ECU carrying out a drive control of an engine and a regeneration control of a DPF. The engine device is provided with an exhaust gas purifying device which is arranged in an exhaust route of the engine, the ECU which controls a drive of the engine, and a variable memory means which stores a general-purpose regeneration program selectively executing a plurality of regeneration modes with respect to the exhaust gas purifying device and a flag table corresponding to an optional regeneration mode, and is rewritable. The ECU executes the general-purpose regeneration program in accordance with a regeneration mode which is selected on the basis of the flag table.

Engine device

An exhaust gas purification device is arranged in an exhaust gas route of a common rail type engine. At least one of an intake air throttle device and an exhaust gas throttle device are arranged in intake and exhaust systems of the engine. In the case that a clogged state of the exhaust gas purification device becomes equal to or more than a prescribed level, an auxiliary renewing mode which raises the temperature of an exhaust gas from the engine by actuating at least one of the intake air throttle device and the exhaust gas throttle device is executed, and in the case that the clogged state of the exhaust gas purification device is not improved even by executing the auxiliary renewing mode, a forced renewing mode which supplies a fuel into the exhaust gas purification device by a post injection is executed.

An engine control apparatus in which a fuel injection apparatus injects a fuel to an engine; detecting means detects a drive state of the engine, and an ECU controls actuation of the fuel injection apparatus on the basis of a detection information of the detecting means and a specific output characteristic data of the engine, wherein compensating means for compensating the output characteristic data is provided, and the ECU is structured such as to compute a limit torque value on the basis of a result of compensation of the output characteristic data by the compensating means and the detection information of the detecting means, and actuate the fuel injection apparatus in correspondence to the limit torque value.

Engine control apparatus

In an engine device provided with an engine which serves as a power source, an exhaust gas purifying filter device which is arranged in an exhaust gas path of the engine, and control means which executes a low rotation control for lowering an engine speed to a predetermined first low rotating speed at a time when a previously set low rotation condition is established, the control means is structured such as to maintain the engine speed at a second low rotating speed which is higher than the first low rotating speed, for suppressing a reduction of an exhaust gas temperature at a time when both of the low rotation condition and a previously set forced regeneration condition are established.

An exhaust gas purification device arranged in an exhaust system of an engine, and includes a renewing device for burning and removing a particulate matter within the exhaust gas purification device. The renewing device is operable in the case that a clogged state of the exhaust gas purification device is equal to or more than a prescribed level, wherein the exhaust gas purification system includes renewal admittance input means which allows an actuation of the renewing device, and rotating speed holding input means for holding a rotating speed of the engine to a predetermined rotating speed, and in the case that a turn-on operation of the rotating speed holding input means is carried out in a state in which an allowing operation of the renewal admittance input means is carried out, the rotating speed holding motion of the engine is executed in preference to an actuation of the renewing device.

Exhaust gas purification system of working machine

A hydraulic transmission () has an electric actuator () for changing its output/input rotation speed ratio. A controller () of the actuator memorizes a command current value to the actuator supposing that load is not applied on the hydraulic transmission, and calculates a value of load applied on the hydraulic transmission by calculating a difference between an actual command current value to the actuator and the memorized command current value. A command current value is compensated based on the value of load, and the actuator receives feedback to be controlled. A vehicle may have a differential mechanism (), which combines rotation powers on input side and output side of the hydraulic transmission. A detector () detects rotation speed of a main speed change output shaft () serving as an output shaft of the differential mechanism. If the detected rotation speed differs from target rotation speed of the shaft () determined based on operation of a speed change operation tool, the actuator is forcedly controlled. This difference is supposed to be caused by load applied on the hydraulic transmission, whereby the load is calculated.
