Abstract: A dosing system for delivering reductant to an exhaust gas treatment system of an internal combustion engine using air driven hydraulic pumps for closed-loop controlling reductant pressure and a two-stage PWM control method for controlling dosing rate. Reductant residue in the dosing systems is purged by using compressed air after a dosing process completes, and when the air driven hydraulic pumps are positioned inside a reductant tank, dedicated heating means for the pumps is not necessary. The air driven hydraulic pumps can also use low pressure compressed air, and the closed-loop pressure control together with the two-stage PWM control allow dosing accuracy insensitive to pressure variations in compressed air. These new features enable the dosing system use a variety of compressed air sources, including an engine turbo.

Abstract: A fuel injection apparatus with a deterioration detection device that includes a volume changing chamber, the volume of which is determined by fuel pressure inside the injector. After injector nozzle opens, the time for the volume changing chamber to change from an initial volume to a target volume is measured and used for calculating changes in nozzle orifice size. The value of orifice size change can be used for both diagnosing injector deterioration and compensating fuel flow rate in a feedback control. In addition to detecting injector deterioration and failures, the volume changing device also dampens effects of noise in fuel pressure to fuel flow rate control and decreases chances of after-injection and second injection.

Abstract: An apparatus and method for controlling a device using pulse signals. In the apparatus and method, a two-stage control is used to generate pulse signals, which can be a PWM signal, a pulse signal including a PWM signal with a sleeping time, or a PDM signal. The two-stage control includes a second stage control, which generates pulse signals according to parameter values generated periodically by a first stage according to a target value and feedback sensing values. The two-stage control can be used in decreasing perturbation in a closed-loop control and accurate open-loop control.
