PURPOSE:To indicate the travelling at economical fuel cost easily by displaying the condition of incomplete combustion by a slow-quick discriminating circuit when the time of the operation of an accelerator pedal is shorter than proper time in the operation of a diesel engine loaded car. CONSTITUTION:A control lever detector 1 of a fuel injection pump outputs signals VL corresponding to the worked quantity of the accelerator pedal and the signals are transmitted to the slow-quick discriminating circuit 2 of the speed of the worked pedal. Here, when the case when the speed of working is faster than the proper time to of the operation of the pedal, where the air fuel ratio enabling the travelling at the economical fuel cost is formed, in the extent that incomplete combustion is generated is discriminated, the output of the circuit 2 is made L, and the red lighting indicator 6 is lit and an alarm is given through an inverter 5 and an amplifier 3. The rise signals A of the output VL of the detector 1 and signals C, to which voltage VD is added in order to give allowance to delay gradually increasing signals B by a R1C circuit, are compared by means of a comparator CM1 and discriminated by means of the slow quick discriminating circuit 2. |
