PURPOSE:To get easy drive, by controlling automatically operation speed based on its power output according to judgement on operation condition picked up from rack position signal of jet pump, engine revolution number signal and from pre- determined engine-load factor. CONSTITUTION:Detect rack position of jet pump which controls fuel injection pump of diesel engine ENG by rack sensor and also detect condition of throttle which is controlled by power throttle PSL using throttle sensor SSL and thus get electrical signal corresponding with torque T. Moreover, by revolution number sensor SRO, get rotation number signal of ENG and further get rotation angle signal of change speed lever 1 which controls speed change gear HST by sensor STR and send these signals to electronic controller CT. Here, by operation panel OP, make comparison with pre-set several conditions and pass judgement and outout control signal and drive electric-magnetic vale 2 to be used for PSL and HST control. |
