摘要:
In a slew rate limiter, a slew rate is limited so as not to pass a signal varying more abruptly than a wobble signal included in a difference signal generated by a differential amplifier, and this limited slew rate is used to process the difference signal to be outputted. That is, the slew rate limiter removes a signal varying more abruptly than a wobble signal included in a difference signal DIFO, and then outputs only the wobble signal. A DAC generates an offset voltage. An adder is used to add this offset voltage to the wobble signal from the slew rate limiter. The signal obtained by this addition as a slice level is compared by a comparator with the difference signal, thereby reproducing an LPP signal.

In a slew rate limiter, a slew rate is limited in such a manner that passage of a signal which changes more steeply than a wobble signal included in a differential signal generated in a differential amplifier can be prevented, and the differential signal is processed with the slew rate so as to be outputted. That is, a signal which changes more steeply than the wobble signal included in the differential signal DIFO is removed, thereby enabling only the wobble signal to be outputted from the slew rate limiter. An offset voltage which is generated by a DAC, is also added by an adder to the wobble signal from the slew rate limiter and thereafter the differential signal is compared in a comparator with the addition signal as a slice level, for reproducing a LPP signal.

摘要:
There is provided a method for fueling a diesel engine having a particulate filter in its exhaust system. The method comprises supplying a main fuel injection to generate a desired torque. It also comprises additionally supplying a first post fuel injection after the main fuel injection and a second post fuel injection after the first post fuel injection during a higher engine load condition. The method further comprises continuing to supply the main fuel injection and the first post fuel injection and stopping to supply the second post fuel injection during a lower engine load condition, if a vehicle cruise control is performed. Therefore, a noticeable torque disturbance can be eliminated.
